So confusing statement..... "Test with your ears is not good advice It's about ad hoc analysis by somewhat trained ears"
? Aren't those two statements in the same sentence mutually exclusive?? What is it you are really after?? There are many speaker modeling and box design programs available with some of the most commonly available drivers already programmed in and you can add your own driver specs for those less common drivers. No one here can give you the exact build specifications so you only have to build one perfect unit which satisfies all of your requirements. EVERY SPEAKER box and driver has trade-offs, some more severe than others. I personally hate the sound of the very common 15" woofer / Horn mid range tweeter units that everyone makes (JBL, EV, PEAVEY, ETC)!!! The woofer is total mud in the mid range area and the horn tweeter just doesn't come far enough down into the mid range area to add announciation to the woofers muddy mid range. But, guess what most small bands use as their front of house system.....The very system I think sounds like hammered shit!! So get behind this idea, there is no perfect combination to satisfy your perfect requirement. With all of the near field monitor cabinets and all of the monitor designs available why are you trying to reinvent the wheel? As for amplifier class, it doesn't matter as long as the specs are good. I recently gave away one of the shitty 500w Class D plate amplifiers and kept the 250w pure analog amplifier because it simply sounded better and the 3dB power loss was insignificant for the venue.

Because, depending on the soundfield caracteristics of a non acousically threated room, a front firing woofer can be a desastrous design (monitors are designed for damped rooms)
The small FR that have been choosen by the author is not affected by the nul and peaks (phase shifts
) of the low frequencies in a normal room... it is good choice

Clearly not. One is about the signal content judged with help of a (hopefully soon to be) verified listening device, and one, that device, aka DIYed special purpose monitor - at the stage of not yet tested veracity, which I cannot meaninfully rectify by playing some music album and feeling "sounds good" - which tells me almost nothing about this except it's not outright broken. These two things are not at the same time. You're expecting to pull oneself in the air on the own bootstraps, as they say.
And a trained ear doesn't mean a miracle device that can do this, this was contextual, as in, trained for the purpose of the analysis of particular types of signals. I did not say "ear of god".QuoteEVERY SPEAKER box and driver has trade-offs
Hence chosing one that works especielly well (according to manufacturer... seem reputable, though) for a limited scenario at hand seems like a good move, no?
Having a 100..12k range is a nice limitation.
And your gear is for improving the economy, specifically in the hearing aid sector - totally different animals than what I'm after.
Next to the fact that your electromechanical instrument amplifiers aren't amplifiers per se, they are tone shapers, too, and the commonly used speakers and cabinets there are total crap for anything except those purposes. That stuff has maximal subjectivity.
Anyway... I'll look again at this stuff ~ on the weekend. -

Interesting! Need look into, for other purposes... Laaaater. -

Have you envisaged the possibility to integrate a small cheap DSP on the AMP board? it can gives you a lot of headroom if there is an unexpected problem with the soundfield... later.
