Nice work! I'd have countersunk the mid and woofer as well, to get a flush front, doubling up the front board if neccessary to have enough thickness to set the screws. Also, I don't like the protruded cable terminals on the back too much. None of that has and influence on sound, so it may just be my OCD talking.
How did you do time align drivers in crossover?? Midrange is like 1" I front of the other?? Did you measure phase response? I learned that never have reflexport close to a wall. Always leave space around it. So it can breath.
Time alignment isn't really an issue there. An inch would result in a 0.07 ms delay i.e. not audible. Any phase issues would come from the crossover but from what I can tell there's no issue. The thing about ports is generally true; they're definitely too close to the walls here as they're completely blocked off (essentially creating leaky closed boxes). You can get away with having them 𝘤𝘭𝘰𝘴𝘦 to a wall as long as you design them with that intention and that goes for all types of boxes.
I'm waiting to hear back from the Hivi company. I need to be sure the dome midrange is still available before making plans available. I'll post an update in the community tab when they get back to me.
Please note that schedule 40 2" PVC pipe has an ID of 2.067 which results in an area of 3.36 in sq, which is larger than using a nominal 2" ID calculation. Always shoot for accuracy
@@mikerick6955 - Most DIY'ers are fanatical about using accurate calculations and using the nominal 2" as the diameter arrives at an 11% miscalculation. To me an 11% error is intolerable. I spent 15 months on an M60 main battle tank and everything above 12khz is a mystery to me, BUT, I still perform the most accurate calculations possible and always attempt to arrive at a full range solution with a decent tweeter.
I don't remember exactly what I used here, but either hot-glue, or a type of super glue. It's admittedly risky if you need to pull the xover back out. More safe play is to use velcro strips on both board & cabinet for easy removal.
I've loved watching your builds. I've been planning on building a higher-quality copy of the Wharfedale Lintons. 3-way with 8" woofer, 5" mid, tweeter. Using hardwood box or hardwood plywood for box. May use MDF for front panel. I'm considering using Datyton Reference series 8 ohm for woofer and mid. Also might use Dayton crossovers. Unsure about which tweeter. I would appreciate any feedback, and maybe this is a speaker you might consider building?
The Wharfedales would be a great speaker to take inspiration from. Dayton Reference Series are great value, and great sounding drivers. Using hardwood or mdf is really up to you. Some hardwoods can be great for speaker cabinets, other not. Just do your research. The most important thing you mentioned is the crossover. A pre-built xover will take the nice drivers, and turn them into something you don't want. If you have the budget, a measurement microphone is would be most useful. If you can't afford one, maybe you have a friend with one. Crossover design relies on having measurements from a microphone, taken from the speakers in the box they will live in. Without this, it is a total guess what will happen when using a pre-built xover. I hope this helps. Please ask more questions if you have them.
"Was not compensated for this video" Yet you got a free 3 way setup, 6 drivers, which do have monetary value. Aside from that, wonderful video, and beautiful work on the speakers.
That's a fair criticism. I could think of a better way to word that. I'm always transparent that things were sent to me, but want to be clear that I'm not being paid to create a video, or say anything nice about them. They get no pre approval of my content. I'll work on how to talk about it more clearly. Appreciate the watch!
Without DSP it can be tough to do sealed drivers. Lower efficiency, and higher roll off without EQ. There are benefits, but mist people are looking for lower F3s these days
I'm a little surprised that these studio monitors are so approachable. Most people who go out of their way to build a set of studio monitors will also use 3-way integrated amplifiers with DSP correction for absolute in-room linear neutral response. The SEAS KingRo4y mk.III DIY studio monitors call for this kind of setup, which makes them quite expensive to build. Seems like the sound quality is worth it, based on the reviews I've seen, but it's still a steep price increase.
@@DIYhyfy DSP correction combined with durable drivers, powerful amplification, and a suitably rigid cabinet are really the only effective means to cheat the rule that there is no replacement for displacement. Combine all of those things and you can get much more powerful bass response out of a speaker than it should really be capable of through conventional means. But the kind of design you used is far better for the average person considering a set of DIY studio monitors, since the barrier to entry is significantly reduced by the conventional speaker design. Fairly simple crossover, standard amplifier requirements, and the drivers aren't even unreasonably priced. I think the only thing I'd bother investigating an alternative to is to find some appropriately sized flared ports to reduce chuffing at high excursion on the woofer. Any other changes would either increase the cost too dramatically or would inherently modify the sound signature (like using a mid-woofer and tweeter with better extension so you can use a dedicated subwoofer driver for the woofer instead of a conventional woofer that just happens to have acceptable low end extension). This is to say that your design looks very good for the intended purpose and audience, so there's little room to improve it without detriment to one or more aspects.
Excellent work!👏 i only have a slight criticism of the lacquer painting technique, use the spraygun at a fixed distance as you spray (robotic movement) ,there is no need to make a circular movement that changes the distance and thus the amount of material coming out so the result will be much better😁
It looks like one woofer speaker suffered a damaged surround in transit. It will have higher harmonic distortion during operation than an unspoiled unit due to asymmetric Kms, and may even present uneven compliance from side to side, resulting in coil rocking if the woofers ever really get hopping. You'll want to replace this unit to get consistent performance and the best longevity from the speaker.
I would definitely agree for the long term. I did also do a listening test in free air to listen for coil rub. Ironically it was the protective cover that slipped sideways and was pressed against the surround for some time.
10 seconds into the video and all i think is: fine looking speakers, but those first reflections and resoances from the table will destroy all your efforts.
A from the ground up speaker build video. Great job!!!!
Bet those would sound good with a passive radiator on the back fully sealed a la ESS.
Nice work!

More to come!
Love your content. Pls include a playback demo.
Great video as always! You killed it!
Why is the veneer orientation different?.

@Undecid just like most polk rear ported speakers with wall hangers from factory.
Awesome video , really made this feel approachable , are the building & crossover plans still available ?

@@DIYhyfy i believe parts express has them, thank you ill be on the look out

awesome build!! amazing work i subscribed
How did you anchor your crossover board in the cabinet?

More safe play is to use velcro strips on both board & cabinet for easy removal.
@DIYhyfy the best way is to buy some circuit board standoffs from parts express.

Do an acoustic suspension build!
Without DSP it can be tough to do sealed drivers. Lower efficiency, and higher roll off without EQ.
There are benefits, but mist people are looking for lower F3s these days
@DIYhyfy AR used to do it without all the fancy computers we have now. The newer KLH series is acoustic suspension.

There are definitely ways to improve with DSP. It really is hard to beat when it comes to low end extension, and linearity.

The midrange is from Hivi. I'm waiting to see if this model is available for purchase. This is not the same model you can find online.

Yes, they certainly would. I mentioned later in the video that they wouldn't be well suited for use directly on a desk against a wall etc.
