TLS guy, checked out your system.
Lots of very cool stuff (transmission line speakers, reel to reels, ..).
It still seems like the rules of physics still count more than marketing ads.
I did some DIY stuff in the late 70's and early 80's.
Had the tandberg 10" reel to reel, the microsieki BL 51 turntable w/ sme tonearm, grado cartridge, bi amped system with Halfer amps.
The DYI audax/polydax speakers had a cylinder for each midrange with minimal front surface area, with styrofoam cone on the inside back to minimize internal reflections.
The paper cylinders were sealed, wrapped in lead and then covered with felt.
The tweeters where adjusted back to provide phase alignment is the crossover area.
The speakers had two external crossovers one for low power (6db / octave) and one for higher power (18db / octave).
And 2 10 cu foot sealed subwoofers with 3 inch voice coils and 3 lb magnets tuned to 20hz -3/db slow rolloff.
BTW, just ordered 2 av123 MFW-15s to replace these subwoofers, downsizing from 21 cu foot to 11 cu foot and removing the last halfer amp doing subwoofer duty.
My last piece of legacy equipment is the ritcher scale 1/3 octave subwoofer eq which was a necessity with low subs.
Probably going replace subwoofer eq with a multiband Behringer parametric equalizer or equivalent.
It seems that alot of these older audio concepts still exist today.
And the upgrade of my college / post collage budget system is almost complete ...
