"I sat down to test and listen to a couple songs, but the sound quality was so engaging I ended up listening to music for the next 2 hours" - says it all about the speakers! And you have discerning taste. So, making a note about these speakers. Using a 5 inch midrange instead of a 3 inch I think is what brings out the best in this speaker. I hate 2 way speaker designs. They always sound "thin" to me. If you are going to take the time to build something, build it right.I'm surprised about the plastic speaker housing though for the midrange. But it works apparently. cool build. I just would have gone for a darker (midnight) blue. lol But they still look decent and are at least not "black". But it's what the speakers sound like that matter.

Nice build. I've heard DIY floor standing open baffle speakers taller than I am that image well with 15" woofers in an WMTMW configuration. They have a compression driver with 10" wavegiude that helps with imaging. I think large baffles can do very well if designed correctly. Also with what you experienced with the bass notes, perhaps having a larger woofer is more important for clean bass notes. If you think about it that 12" woofer only has to travel a couple millimeters to produce bass notes at a decent volume compared to say a 6.5" woofer that has to spend more time moving 3x that distance creating more distortion to make the same volume. Also your not driving an amplifier as hard with those more efficient larger woofers so that is less distortion again. For critical listening its those minor improvements that make some difference. I'm glad you hear such a great result with them.

I made these and thought they were ok. The dc130 is quite a good IMO, as if the woofer, the tweeter I do not are for at all and don't think it was a great choice here. The midbass dip is mostly what I consider to be a result of inadequate data set for the filter design state. Paul's sim shows effectively opposite response in the 300hz region, with a difference of about 5db, quite a lot. It can be tough to get accurate information to work with in the lower band of a 3 way speaker so this different isn't that uncommon. You can fill it back in with EQ or change a few values on the stock xover which also gives better phase tracking between the woofer and mid. I also replaced the Peerless D27 with the Dayton nd25fw and found it to be a considerably better match in terms of on and off axis response, the xover needs modification for this but it is cheap. I'd love to see Paul utilize virtuixcad in the future, I think it would help him out a lot.

Perfect timing, I just got 2 10" Dayton designer woofer and they are monsters, I'm going to be using difference mids and tweeter and build my own design. I pulled of a 2 way with a Dayton 10" reference paper cone woofer. Which a lot of people said you can't build a 2 way with a 10" which was hard to pull off but it sounds amazing, so now I'm planning a 3 way. As far as imaging, you are 100% if you design and plan the crossover to cross before the drivers are beaming etc. They don't have a problem. I think you need a 10" or 12" woofer to really get that mid bass and hear those kick drums sound live. I sit and can't stop listening to all the new things I hear in songs that I have heard a million times. Unfortunately I haven't seen the Dayton reference 10" paper cone woofer on PE website, but I got an open box with a 25% on top of that off on a pair of Dayton designer 10" woofers with aluminum cones for a song. So it looks like I'm designing another speaker . The problem is I have 3 other projects I need to finish ahead of it , full time job and a relationship. Last time I picked the speakers over the girl. Let's see how the new one goes 😜.

Off centering drivers is a great idea. It wouldn't be tied directly to distortion. Distortion is a product of driver non-linearity. This is handled in the crossover. Off centering the drivers would help with surface reflections. These reflections create nulls & peaks in the frequency response. Tying it more to tonality. Thanks for watching!

@@DIYhyfy I think he was thinking of diffraction. But I am in the process of designing something similar, I am going to use MDF and then a 2" thick piece of maple for the baffle. That was with the 2" thickness I taper the top making it narrow with a 45° angle down to the woofer which I want to make wider. It's a little extra work and money, but I have been thinking about the best way. I was going to move them to the outside (t+w) and then I saw a pair like that and liked it. I have a pair of 2 way I designed with a 10" Dayton reference paper cone and I think that's the only woofer I found I could crossover at 1400 without breaking up and after hearing a 10" woofer you can't go back.

Looks outstanding. I've always wanted to build a 3-way "party speaker," like the ones I had in the 70's. What is the black material that was laminated to the sides, and why only the sides? How were the corners of the MDF sealed before painting? MDF is notorious for soaking up paint and preventing the creation of a smooth, shiny surface; yet you managed to give the corner paint the same quality surface as the rest of the cabinet.
@DIYhyfy
22 күн бұрын
Hi, the laminate is Formica. It's only used to cover joints. Hence it only needs to be used on the sides. (Assuming you've designed the joint to be on the sides only, like me). The primer is sandable rustoleum primer. I would recommend 2-part epoxy automotive primer for easier sanding, but it's more expensive in a rattle can.
@bruceandt

The jointing could be improved with miter lock jointing. Also cutting grooves in the cabinet to receive the internal bracing. It did however look like a solid build. I have thought at length about the external finish of a cabinet. With what people are doing in the car industry? I thought it might be bad ass to finish the cabinets in a rap.

Is the PVC midrange hood part of the original design? I’m guessing that its resonant frequency wouldn’t be excited by the mid driver, but would by the woofer, since they share the same larger cabinet. Have you noticed this to be the case? Either way, it’s a beautiful-looking speaker! I respect and envy the heck out of your rattle can skills!

Hey, I did wonder this myself. The inside of the pvc is damped with dacron, but the cap itself isn't damped apart from being rigidly mounted to the baffle. Paul Carmody used the same setup, so I just trusted his judgment. There's no audible resonance from it, that I can tell. Thanks for watching!
@practicalguy973
22 күн бұрын
Considering the size of the PVC hood I would assume the resonant frequency is higher than the crossover point of the 12" woofer. On Paul Carmody's DIY speaker site, the frequency response of the woofer starts tapering off at 300hz. There might be some energy that excites it but probably very little to be audible.

As far as port noise, none so far at any level. I modeled the response myself since I actually changed the port diameter. Air velocity was a bit higher than the rule of thumb, but not bad enough to be audible in any listening I've done so far.
