If you guys were to choose between one of the dual 7" woofer + a7/10/12 designs or an OB setup with a 15" woofer + a7/10/12 per side what would you pick?

I’m no big fan of OBs. All i have heard have had something common i did not like.

I have a pair of Alpair 12pw. I think I like the look of the Woden design folded MLTL for the A12pw. I am now trying to figure out what to build for the midtweeter. I have a pair of the A10.3 and a pair of the Eikona 2 that I can use. I also plan at some point to tryout a Heil AMT and possibly an A5.3 on top of the A12pw MLTL. Since I plan to swap out the midtweeters, would I need to make dedicated midtweeter enclosures for the A10.3 and the Eikona 2? Or could I build a Trapezoidal Mar-ken for the A10.3 and use it upside down for the proper driver elevation ? I could build a different monitor for the Eikona 2. I have other locations to use the monitors when they are not on the A12pw MLTL. Would this be too much of a compromise? All the midtweeter/fullrange boxes I have seen would have difficulty playing fullrange musical content on their own.

You could try both on an OB above the A12pw.

Do you have Heils already? The ones i heard were lovely. If you can get the XO right these could be fantastic. Alpair 5.2/3 (very little difference) might actually have the edge, particularily with a lower XO.

I’d suggest something like 4th order 1kHz for the AMT. Depending on how loud you want to play, the A5x could go as low as 250 Hz with a lower order XO. This is the range where many of the evils of XOs become much less problematic.

The 2 larger drivers have decent bass on their own, where do you XO them?

The Mar-Ken10.3 would make a fine satellite, as a nidTweeter greater levels than w smaller drivers coud be attained, and one could experiment with adding dampin gto the vents to push the box even more towards aperiodic.

There are also trapezoidal miniOnkens for A5x, and the Eikona. And for the A6.2m/p that often get overlooked for this duty.

I don’t have the Heils yet. May be a while. I don’t finish things all that quickly. Currently building 15” Rythmik subs for my home theater. Then I can work on the stereo speakers (the A12pw). I was thinking about putting the Eikona in a OB. Should be simple to implement. I intend to play around a bit with the crossovers. I have a Hypex DLCP unit which I can use to try out different crossovers. I can always implement with an analog crossover later. I will have a multitude of different amps to try out once I finish building them.
