Im doing a mini PA system with 4 of these and 2 subwoofer

Let compare to Wiim Amp, which one is the better choice? Thanks

Please try / review the V3 mono. They are very good.

checking the build plan and the driver's data Sd, Fs, Qts- it's obvious that the TL length should be 18 cm longer to effectively apply the driver. What's the Ftl you got?

4:40 you don't need a bigger amp for bigger speakers, it's the other way round. Bigger speakers are usually more sensitive so they play louder for 1 watt than a small speaker.

The Dayton sounds best as a midrange.

The Aiyima sounds much better! More totally accurate and better bass!

0:25 No, no, zed is quite all right. The Yanks can ruddy well learn to speak English proper like.

I found it very painful watching someone with a dangling hoodie tie cord leaning over the blade using a table saw. This is two years after, I hope you have not been sucked into the blade. It looks like a time factor though.

I could hear a difference but I would like to be present and hear them again before picking one over the other. I have the CHR-70 in a double mouth horn enclosure I built. The bass isn't great even with that cabinet. On the Madisound site where I bought the drivers, they recommend a 100 hour break-in period which seems excessive to me. I am a fan of both Markaudio and Aiyima. I hope that Aiyima will listen to customers and start to send gaskets as well as better screws like Markaudio does. Thanks for your hard work on this, Paul!

I can see following the use of the golden ration in planning the front layout. But as the ratio is normally applied to an image created in 2D. How does one asses the depth of the cabinet for a golden ratio. Ok, its simply using the front size as one multiple of the wanted enclosure volume size to give the depth. But is the depth to be related to the golden ratio also. Therfore giving a golden ratio application from all perspectives not just the speaker front, which is the golden ratio but it can still be varied in size depending on what is needed for the depth. Is there any relationship between the area of the golden ration front and the depth? or just work it out from the box volume and a random front golden ratio size and that will do?

0:40 If you build speakers yu an audiophile.

I got 2 of ZA3 ( working as mono power amps) upgraded by installing Sparkos Dual opp amps SS 3602 and all works great :-)

Thank you for showing this. BUT: Whatever this constructions is: It's not a transmission line. I don't know if it's the correct english Word, but I would say it's a kind of "Horn"

The optimal volume is 26 liters (bass reflex) to which you must add the volume of the magnet and the volume of the tube. The 5 cm tube (real diameter 4.8 cm) must be 8.2 cm long It is advisable to also try a shorter tube 7.2 cm or longer 9.2 cm The tube should resonate at 43Hz In a closed box without bass-reflex con12.5 liters you have the best transient. The zobel network (RC series) sufficient to make it work with class D amplifier must be made with 2 non -polarized capacitors from 0.82 UF 100 volts and 2 resistance from 4.7+3.9=8.6 hom 20 Watt (10+10)

Is all that necessary for such a small driver, or is that what makes it so a small driver can sound much bigger?

How did you calculate the TL air volume and length.

Would love to see a measurement of the frequency response of this design. Klippel measurements would really be fun to see the dirty details of how the golden ratio worked out for this. Great concept!

Great Video! Having said that, would you please use a shadowed font next time? It was hard to read the comments. But the rest? Excellent job!

Le gruyère du milieu ne peut être qu'une mauvaise idée vibrante.

great looking pair , and sound great too.. Kudos.

Aiyima's seem way brighter

How this compare to V3 or to za3?

Great build, great video. I am just missing the final measurement of your speakers. Would be nice to see the curve

Very nice build but I bet you were disappointed with the finish on the wood? RUclips is fantastic for learning how to build things but woodworking youtubers never finish any projects well. As a French polisher it is easy to get a flat mirror finish to any woodwork and you are never going to rest a hot cup of tea on these or put them out in the rain so why not use French polish? Follow these steps, 1) sand flat 2) mix thin french polish with pumice powder and work the area with a fad/rubber in a round motion, the very fine sawdust will fill the grain 3) sand with 400 grit 4) apply many coats of french polish with mop brush in long strokes leaving time to dry in-between each coat (on a hot day less than 10 mins) 5) use the fad/rubber with thin french polish to smooth out any brush marks and leave a very shiny finish 6) use 0000 wire wool and very lightly go over the finish to take off the bright shine then use wax polish and buff after. This sounds long winded but using other methods is longer because drying time with french polish is so quick, first timers don't be afraid of trying french polish, it's cheap, long lasting, robust (unless getting wet) easy to repair, and if you mess it up easy to remove and start again. Oh and it looks amazing. I will leave a link to a guy on youtube who has how to videos on french polishing, he is the best, ... www.youtube.com/@theenglishpolisher

Nice job, but I have one query which relates to why you wanted to be able to screw down the backpanel. I would build a screwed panel for protyping if say I had a crossover and I wanted to quickly swap in and out components, but you have a full range driver that at best might have a resistor for the top end. Just curious as I think that screws always betray the fact that it is DIY..

What a great video and stellar job! Great instructions!

Great build although I don't like the glossy veneer at all.

Very nice. A couple thoughts: 1. I just opened up some old Bose 301s. Instead of solder, they used wirewrap. 2. If someone wants to solder to anything, first make a mechanical connection (i.e. twist the wires together) and then solder to make the permanent electrical connection. 3. Those positive and negative tabs: If the top tab gets loose after a could years of service, it looks like the tab could possibly swing down and make contact with the other connector. Maybe not, but that's something youtube DIYers should look out for. This video has motivated me to make my own soundbar. Again, very nice video.

What is the cross sectional área or dimensions of the channel?

I wish there were more videos of people taking old speakers and rebuild them with new speakers/crossovers. I don’t want to build the cabinet.

Beautiful!!!!

If only I have those tools and space I would like to make a pair myself. I love full range driver that does not need cross over. Clean sound.

Which power supply would you recommend to upgrade to. I am currently using 24v 4.5A supplied in box but at high volume it does not work properly

Ficaram muito lindas

Hallo, are all fullrange project with ayima drivers without zobel filter? Grazie

Really well built!!! Respect, and the speaker also seems to be very good in the upper range for a full-range driver. Very interesting! Great video! 👍

Hello. No explanation about the filters and bass reflex. Good job anyway

Video volume was very very low, had to crank my volume way up.

😮😮 alors là je suis épaté de votre travail au départ je pensais que vous allez montrer comment monter des autres par heure et toutes les systèmes😊 pour le haut-parleur mets pas le carcasse que je pensais p j'adore qu'on s'est muet par contre ça m'intrigue pourquoi vous avez dit chaleur chaleur chaleur chaleur plusieurs fois dans la vidéo vous avez répéter ça deux fois de suite😊😅😅p CDTI défaut ça arrive mais je suis un peu étonné que vous passez du fer à repasser sur du bois

You should try using Rubio Oil + 2C for your wood finish instead of veneer :). Better finish, BIO and quick dry. And with 1 liter you can make almost 30m² of surface area. Very very good product.

Merecem sim um amplificador valvulado!😉

Great Job! Thank you so much for this video.

I hate tiny drivers 😒

Absolutely magnificent speaker design and build! Congratulations.

😆Like soviet sound from 1960

you need an electric screwdriver with preset torque.

Master piece

Beautiful work

Beautiful work but sooo much work for such a little pair speakers and no tweeters 😊😊😊😊😊
