I had never considered that bass (distortion) harmonics would be more audible due to the F-M curve (I don't recall this ever being mentioned in any subwoofer description [magazine tech article or product brochure]).

Digital pre-distortion could be an economical way to lower the harmonic distortion of entry level subwoofers w/built in amps.


Got AT&T fiber ~1 year ago, been cruising thru YouTube videos/audios, found this:
(I don't know how accurate the frequency display is, but my PSW108 seems to slightly exceed its spec)

Getting back on topic!

Progress stuff
This is what the new speaker is looking like, using the good ol SM2 for scale:

And the box insides looks like, noting we are keeping the panels as light as possible with one central step-up box

The boards and stuff is in prototype manufacture now. If you buy 2 sets you get quad!!!!!!!!!

Is the angled part causing the speaker to stand specially designed to route the sound out of the back toward the front?

Nup, it really starts to throw the sound to the sides, when you measure the polar response the thing is virtually an omni, like our previous Nakamichi dragon

I'm still intrigued by the combination ES speaker stand and sound diffuser, in the picture. it looks like a flat surface, maybe a curved surface would better diffuse the sound from the back of the ES speaker, getting even closer to true omnidirectionality.

Trying to keep it as simple and cheap as possible while retaining the slim profile. Also doing a flat pack "ikea" style 4 screw assembly. In practice the frequency response is flat at all points around but there is an overall level shift. If I get time next week I might do some plots

I payed $30 - $35 for each of my Polk T15s, I'm hoping the Involve Audio ES speakers will be in that price range (my friend has 2 Magnaplaner speakers which I've listened to often, I've rarely heard ES speakers though). :)
