- This video shows recording of my DIY loudspeakers. It's a two-way closed-box active loudspeaker. I used Faital drivers: HF1440 compression driver for high frequencies and 15FH500 15" mid woofer for mid and bass frequencies. On this recording the compression driver is crossed to mid at 1000Hz using 2nd order Butterworth filter.
Speakers are powered by two Hypex FA123 amplifier plates.
The enclosure is about 60 cm wide and was made triangular to be placed in the room corners. Wide baffle should make the sound more dry. My room is very lively: there are a lot of reflections. Drier sounding speakers help to reduce the hum of the room.

Ten film pokazuje nagranie moich głośników DIY. To dwudrożny głośnik aktywny o zamkniętej obudowie. Użyłem przetworników Faital: przetwornik kompresyjny HF1440 dla wysokich częstotliwości i 15-calowy głośnik niskotonowy 15FH500 dla częstotliwości średnich i niskich. Został użyty filtr Butterwortha drugiego rzędu przy 1000Hz.
Głośniki zasilane są przez dwie płytki wzmacniacza Hypex FA123.
Obudowa ma szerokość około 60 cm i została wykonana w kształcie trójkąta z przeznaczeniem do umieszczenia w narożnikach pomieszczenia. Szeroka odgroda powinna była sprawić, że dźwięk będzie bardziej suchy. Mój pokój jest bardzo żywy: jest wiele odbić. Bardziej suche głośniki pomagają zredukować szum w pomieszczeniu.
В этом видео показана запись моих громкоговорителей, сделанных своими руками. Это двухполосный активный громкоговоритель закрытого типа. Я использовал драйверы Faital: компрессионный драйвер HF1440 для высоких частот и 15-дюймовый среднечастотный динамик 15FH500 для средних и низких частот. На этой записи компрессионный драйвер пересекается с средними частотами на частоте 1000 Гц с использованием фильтра Баттерворта 2-го порядка.
Динамики питаются от двух пластин усилителя Hypex FA123.
Корпус шириной около 60 см был сделан треугольным, чтобы его можно было разместить в углах комнаты. Широкая перегородка должна сделать звук более сухим. В моей комнате очень оживленно: много отражений. Динамики с более сухим звучанием помогают снизить шум в комнате.
Sounds great! They look beautiful. Nice job!
Thanks!
Hi Ivan, I recently got the FaitalPro HF1460 (Textreme/Carbon membrane) and can only wholeheartedly recommend them:
- They are very linear in the ES600 horn
- They sound slightly softer but also smoother than the titanium SB Audience 65CDN-T (and much, much smoother than most titaium drivers)
- The high frequency detail that I hear in them is just astonishing. Things happening way back in the soundstage that I never heard - I hear them now. And it's not because of a wonky frequency response or "false detail" from too loud upper frequencies. The Textreme driver can just resolve better.
Some may insist in a metal dome driver because they like the "zing" that they have. This Textreme driver goes more towards a really good soft dome tweeter like Dynaudio Esotar, while covering a broader frequency range and having much more punch.
I love the HF1460 from FaitalPro. Took a few weeks to be delivered, but not months like originally indicated by BlueAran. Was worth the price.
Thanks for the review!
Tell me more about them, i want to load them in JM Lecleach 425 horns, what are you using for higher frequency
Hey Ivan I built these speaker as well! Also used the FA123 from Hypex, and in my case the woofer is the SB Audience 15OB350 and compr. driver is 65CDN-T.
I eventually 3d printed the ES-450 horns and they work much better at 600Hz crossover and first-order filters than the ES-600.
Those real wood horns look gorgeous though! Will test a bit more and who knows, maybe find someone who can machine me the ES-450 horns here in the UK.
I thought about ES-450 as well! However, these are wider than the woofer section.
How much polishing did the 3D prints require? Did you use some kind of glue to smooth the surfaces?
@@IvanNikitin1 One ES-450 horn was 8 parts on the printer, so naturally there are small gaps and steps to fill/sand away, as much as the general surface. Lots of sanding and filling and still only acceptable with matte paint. I'd guess around £100/horn in materials and many hours of finishing. But then the wooden horns would be so much more money...
Hello! the SB Audience you use in OB or sealed/BR enclosure? Thanks!
@@demerzzel 75 L sealed. My enclosure is screwed, not glued, so I could take of two panels and have OB configuration after all.
Hi Ivan! gorgeous speakers
Did Joseph Crow design these cabinets? I just built his 1786 cabinets for my horn speaker build and am so happy with the outcome! Beautiful speakers man!
These are inspired by Crow. Mine have much more bracing inside and another driver.
Потрясающая работа! Интересно, как далеко разнесены срезы фильтров что бы встретиться на 1000 гц
I need more and more demos.
Interesting microphone setup. I wonder how eqing with measurments for separate right and left channels would affect the resulting correction
Separate channel equalization doesn't sound right, if we equalize mid and high frequencies. Separate equalization sound well when equalizing bass frequencies.
I have a particular interest in your speakers since I built a 3 way using FH500 bass, mid is an 18 sound 8nmb420 8 inch driver) and smaller 1 inch horn, Faital HF 108r. I also used a Hypex Fusion FA253 amp. I'm very happy with the results but my bass is ported in a 115 Litre box. Your horn looks very nice in wood with smooth round edges. Does the bass mid sound ok up to 1000hz? , no off axis issues? I bet the midrange phase response is excellent with that horn from coming in so low down. Nice job !
I have no complaints about FH500 playing that high. I suppose, that in a direct comparison smaller mid may sound better, but the sound I get from FH500 is very satisfying.
This compression driver can play lower. In a HF950 horn it can play down to 450Hz and still have lower distortion at this frequency than 12” Beyma midwoofer.
The idea behind a 15" driver playing 1000 hz is that the directivity is similar to the horn. When you use a smaller midrange driver you will get much wider dispersion of the midrange. It is counter intuitive but the matching of the woofer to the horn is very deliberate and it is about directivity. If you use a smaller midrange the dispersion might not match in the midrange.
Can I get the dsp file for miniDSP since I don’t have hypex
I'm looking for a new horn speaker project. Do you have a preference over your last design. It goes without saying, beautiful build and congratulations.
Yes, I feel that these speakers sound better. I have a quite lively room and 60 degree horn seems to work better in a such room that 90 degree horn I used to have previously. I'll make a video comparing 60/90 horns.
Иван, какой вы молодец, продолжаете экспериментировать:) скажи а почему от открытых систем ушли?
Сделал закрытую систему (ЗЯ) потому, что руки чесались. При включении в том же помещении оказалось, что ЗЯ на тех же динамиках звучит натуральнее, чем ОЯ. Я 2 или 3 года жил с той закрытой системой. Сейчас просто сделал ещё одну ЗЯ "на богато".
@@IvanNikitin1 кстати, хорошая новость хайпекс выпустил новый платы усиления , но пока просто платы не для актива, который в 10 раз превосходит НС, как они сами заявляют, через год обещают делать новые модули на этих платах, так что в скором думаю у вас будут изменения:)))
@@user-nf8yr9ke7n к сожалению, они и по цене мощно ncore превосходят.:(
have u compare to 18sound 1.4"? or beyma 755nd. Im looking for the best 1.4" driver and it seems i just need to buy each to test lol. so many drivers!
I never personally heard these two. I did own RCF ND950 though and heard ND940 on several occasions. These are also very good drivers sounding great and with very low distortion, but I personally don't like the slight sound color the titanium diaphragm gives. My room is quite lively though (not enough sound absorption): it amplifies the effect the titanium diaphragm gives. If your room is well damped, titanium will be fine. ND940 and ND950 are also priced very reasonably.
Wow. Great. Btw how did you decide to use that woofer in closed box the ts params don't seem it should work but atleast from what I can hear it surely does. So does this qts & vas really don't matter that much? What's the internal volume of the box?
I chose that woofer due to its capability to play well at lower volume. Most pro-woofers are designed to play at very high output levels and they tend to lose music details when playing at lower volume. Since my system was built for home use, I needed a woofer that plays well when playing quiet. The woofer needs a relatively lowish moving mass (Mms), soft suspension (Cms) and yet strong magnet (BL). This woofer series fulfill these requirements. Also, they have the best acceleration of 15'' woofers currently produced by Faital. Acceleration can be estimated by dividing BL by Mms.
My system is an active one. This means that I can correct frequency response and Vas doesn't matter that much. Instead, Xmax and max power are of a higher importance. I needed a woofer that will survive 95dB level @ 40Hz.
How are both of the subs connected and how do you influence their frequencies? I have a peerless XXLS10 here, which has similar parameters and I dont like the built-in (manual) filtering option
@@MrSl1x subs aren't connected yet. They were part of the previous system and serve as lamp stands at the moment,.
How do you find the Joseph Crowe horn vs. the RCF HF950? Also is the Faital Pro tweeter in your opinion better than RCF ND950 and if so, what's the difference?
RCF loads the driver much better - you can cross it at 450Hz vs 800-1000Hz when using ES-600. The RCF has much better directivity control: at 1000Hz the ES600 vertical directivity control. The RCF maintains directivity control down to ~500Hz.
I didn't hear any honkines from both horns.
The ES600 has a narrower directivity which makes the sound in the room drier. For my room this is a plus.
The ES600 looks much better than RCF. RCF was already scary before, and the new batches are made of some spotted plastic.
I can compare Faital HF1440 to RCF ND950 and ND940. I owned both ND950 and HF1440. I decided to keep the HF1440 because I can't hear that ketone diaphragm resonance at 14KHz. When I had RCF, I was constantly paying attention to the resonance of the titanium diaphragm. However, I think the RCF ND940 is the best option of the three because it has a more even frequency response than the HF1440, can be used with a passive crossover, and it is much cheaper. The HF1440 is definitely not suitable for use with a passive crossover.
None of these drivers can match the best dome speakers in reproducing the 10th and 11th octaves. They make up for it with dynamics and realism.
@@IvanNikitin1 I have now Sica 95.44-poly in my DIYs with 1500 Hz dsp-crossover, but been contemplating how much better as a point source it would be if more would be reproduced with the tweeter than now. Would allow also using larger bass-midrange, and could have enough capacity for small scale PA in addition to the hifi use, my current DIYs are not loud enough for that.
@@karoliinasalminen i liked how it sounded with lower crossover point. There is another option to get point source though: get a coaxial like Sica 12 C 2,5 CP.
@@IvanNikitin1 Well my idea all along was to make coaxial benefits without coaxial and without compromises of a typical coaxial. Would buy Genelec 8361 if I wanted coaxial without compromises. A low curoff horn is a more reasonable project as DIY and also will work better in actual PA-use. As can use 15" bass-midrange and bigger than 1" exit compression tweeter that can put out seious SPL. Anyway, our home has walls that are windows from floor to ceiling and fixing their acoustics is kind of impossible, so will need very directive speakers to not listen mainly to the room. Currently Genelec 8050s in living room which sound good, but the amount of room in the sound is more than a low cutoff horn would enable. Even my 1500 Hz horn with my DIYs don't solve the problem because the critical 1 kHz region is still reproduced by the bass-midrange and that happily bounces in the windows. Need controlled directivity as low as possible. And in the search of perfect compression tweeter. Sica 95.44 does not have the titanium reaonance but it is quite soft. A bit like a soft dome. When compared to Genelec 8050 in near field, the 95.44 loses to the Genelec's aluminium dome at the highest register, it lacks some shine and sparkle.
И как в сравнении с RCF рупором? Больше всего интересует тот момент, что у HF950 дифракционный слот есть, а он как многие пишут дает призвуки, хотя здорово расширяет диаграмму.
RCF значительно лучше нагружает драйвер - можно резать при 450Гц. У RCF знаачительно лучше контроль направленности: ES600 теряет контроль по вертикали уже при 1КГц, а RCF сохраняет контроль и до ~500Гц.
Я не слышал призвуков от RCF.
ES600 имеет более узкую направленность, звук в комнате суше. Для меня это плюс.
ES600 значительно лучше выглядит. RCF и так страшный, а новые партии сделаны из какого-то пятнистого пластика.
Если внешний вид устраивает, то Hf950 лучше из этой двойки
@@IvanNikitin1 а пластик какой? Полиэтилен, поликарбонат? Покрасить чем то можно?
@@user47859 экструдированный полиуретан. Красится автомобильными красками, но трудно. Лучше спрятать за сеткой как это делает Клипш.
Sounds pretty naturally but too soft for me. A super-tweeter would fix this I think. However with an existing configuration I don't hear Hypex. That's a big thing
Are the subwoofer engaged?
Nope. They are just lamp stands at the moment.
@@IvanNikitin1
Don't need them from what I can hear.
Я так понял, что тянуть драйвер как можно ниже не всегда и нужно?
Эта дудка плохо нагружает драйвер ниже 1 К, а направленность по вертикали теряется при ~1.5К
А почему 3к долларов? Судя по всему, вы же не готовый рупор купили у него, а модель и сами заказывали изготовление.
Усиление - 1К, драйверы - 1К, корпус и дудки - 1.5К
Прям двухполоски, ага.. А сабы на полу типо тумбочки и не играют, а тупо держат лампы?) а все низы вот эта шляпа хлопает, даже не двигаясь?) ну-ну...)
сабы на этой записи даже без усилителя. они не могут играть. Если динамик двигается при игре - это перегруз и искажения.
@@IvanNikitin1 а ты поноси микрофон во время игры мимо них, и мимо колонки? Чтобы без обмана? Особенно хочется во время партии ударников это услышать))
@@imiafamily мне что делать нечего, чтобы какому-то анониму без единого видео что-то доказывать?
@@IvanNikitin1 правильно, ничего не делай.. Всегда найдутся тупые лохи, которые будут верить на слово...
Косые особенно любят это дело - пихают мастеринговую запись, якобы она так звучит))
There is too much distance between the main speakers between them, I preferred the old version with RCF + RCF Horn HF950, these have too closed dynamics in the middle gamma , probably the material of the horns , beautiful , but not musical, the Great Mr. Shindo said to me, wooden horns there is none that sounds uggual to the other, but they are good for the fireplace in winter.......
I agree that OB speakers sound nicer on the recording. Mics greatly influence the recording quality. I used to have €1600 omnipolar mics + €300 audio interface. This recording was made using €300 cardioid mics + €150 interface since i don’t own the expensive equipment anymore.
Distance is OK IMO: musician images are between speakers and they are palpable. So that 4m distance between speakers is ok for them.
