The Peerless XT25 (really all versions, but the double-magnet one is best) in the Visaton W148 Waveguide is known to perform exceptionally well.
Although you do need a 3D printed adapter to mount clean and flush.

Glad you never gave up. It's really fun seeing the community rally around someone struggling with their project.
Heissmann sells an adapter https://heissmann-acoustics.de/en/produkt/adapterplatte-waveguide-hochtoener/
Why are you guys suggesting something that doens't fit my baffle cut outs lol. Going off topic keep it focused please.
Had to hook the speakers up again to active setup, man I really missed this dynamic range. You just can't get this clarity at higher SPL's from a single 6.5" Amigas really lose energy in the woofer where these just don't care. The mid range detail is just great.
Been playing stuff from Sohn's latest album on repeat, you can really hear each vocal very distinctly.

Steady on. At this point, nobody has a clue what you're intending to do other than saying you wanted a waveguided Peerless.
And folks have been more than patient and helpful, IMO, even when you were saying you were going to scrap them, build a 2-way, then rebuild the cabs, then change the bracing, give up on them again, use different drivers. I'm out.
^^×Yes, it's lot of fun to plug in big speakers. There is no return to smaller ones after that. Even though listening level was modest it's just different, smile on the face even if the system wasn't flawless.
Well, better not generalize too much, perhaps mighty fine small speakers exists.

Been looking around but does anyone know the filter orders for EQ APO's high and low pass filters? To my eyes it looks like one filter results in first order 6db slope, and stacking another gives you 12, but not entirely sure.
Using two filters per HP and LP task seems to give me pretty good looking response in the real world, but curious if there would be benefit to using fourth order filters. The ND25FW doesn't seem to be complaining with two filters.
This is what the slope looks like with two 2500hz hi pass filters in EQ APO

Surprised people are so responsive after I basically felt like I had wasted my time and was stuck in perpetual flip flopping mode. It's just one big learning experience. Hopefully in the near future these will be finished. I'd like to order some Walnut veneer for them.
You may need to upgrade your tweeter. The DX25 has quite a high odd order distortion profile:

compare with my current experiment (SB Acoustics SB26ADC) - which has similar T/S params. This is at a slightly higher voltage to offset the nominal 2dB sensitivity difference to try and be fair:

Re Equaliser APO you may be better off with a new post in the Source and Line -> PC Based forum
We've all been there. It's coming back that's important. I once couldn't look at my project for a week because I stripped a screw so badly and it was stuck.
Ok - so I had made a mistake. visually scaling port and nearfield woofer response is not very scientific!
Using the formula
20*log(Area Port / Area Speaker)^0.5
I get a scaling factor of -8.09dB. This provides ~ 3dB more gain from the port than I applied.
I'll redo the sequence, but you are welcome to do the same on the MDAT I shared

I'd like to get a DXT, but that's a ways off. Not sure how warranted it would be as I find the nd24fw totally acceptable. I really have no complaints with this tweeter.
Yeah with continued listening I see no reason to move beyond the ND25FW, sounds fantastic. I think a lot of my complaints on imaging were do to my placement. Not really hearing any problems with the 3k region on the dc130 as someone mentioned. Kinda hard to really confirm but I feel the bracing I added tightened up the woofer region a lot and the additional changes in mid stuffing had helped.
I really want to get some filtering on them where I know more about what's going on and using more standard options like BW and LR. Not to mention coming out of 3.5mm mobo sockets introduces a good bit of PC thinking noise. A simple DSP408 seems affordable to be able to test out filters.
If anything gets a tweeter upgrade it will be the Amiga. I might have to test them with an active xover to see what could improve with the current drivers. Going from something tuned neutral to the Amiga kinda annoys me. That's for another thread though.

Then who are we to advise you otherwise. Cross it at 2kHz, I guess you have a directivity match. The only concern I would have is it's distortion pattern. Our Italian friends measured data that not really convince me. The DXT, a SB26STWGC-4 or the H2606 do a better job.
Huh? Not sure I follow, I cross the nd25fw at 2.5khz. The CSD on the SB looks considerably worse to me than the ND25FW so I don't see that as an option. I don't really hear any distortion at high levels either.

I wouldn't discount the importance of directivity in a build like this. It's one of the fundamental advantages of using the midrange. Lobing doesn't seem like a huge problem when your sound power is clean and flat, but we listen in rooms and the effect of that shouldn't be underestimated. Are you using VituixCAD yet? It's very helpful.
