I keep pulling the same driver from commercial home theatre systems SAMSUNG / SONY / LG. Volume-wise it must be the most prolific 6.5" sub on the planet. From my subjective tests it seems pretty good.
I now have four of these drivers surplus to requirements. I'm considering building a pair of compact subs with twin drivers but I can find no technical information.
Anybody?
My bad: 6.5" woofers/ subwoofers east tech/Sony /JVC lot of | Reverb

Errr, measure it. I do it the easy way with an old Smith and Larson Woofer Tester, but with a precision resister, you can do it with Limp and a PC. A lot easier than the old days where we did it with a signal generator and a VTVM.
Without basic measurement skills, you won't know if your design is valid or is you achieve it.
Second requirement is a mic. You can buy one or hope a Panasonic capsule is good enough. I got by with a DIY capsule for years. More than good enough to build a sub.
I do not understand why so many are obsessed with trying to defy the laws of physics with tiny subs. Not saying it can't be done somewhat successfully, but the right tool still does a better job.

Dayton DATS V2 or V3 will do all of the TS parameters along with a ruler and 50 grams odd for the "added mass method" is the easiest way I've found.
Although I like my WT-II ( DATS basically a copy) please look at this software
ARTA Software
Read the manuals and it will teach you a lot about what you need to measure and why. If doing a single one-off, you may not want to invest in a lot of tools.
Review Siegfried's pages and trad about how to make a good quality capsule mic really cheap. Parts Express also sells a USB mic darn cheap.
Linkwitz Lab - Loudspeaker Design
I use the WT-II a Behringer 8000 mic and a Focusrite IO box, but I have been doing builds off and on for decades, so investment was worth while. DIY is not always cheap, but a lot of fun and frequently we can do things you can't buy. I tune my crossovers not for free air 1M flat response, but for in-room response. in MY room.
If you intend to build more than one project , about $200 in tools is worth the effort. If just looking at some scrap drivers, e-bay may be the smartest option.

I need to push back on your assertion. I have a couple of 2.1 systems in my apartment. On my desktop system there's an 8" sub which is literally 6" away from my feet. In my bedroom system there's a 6.5" sub under the bed, separated from my head by the width of the mattress and a pillow.
My home theatre system contains two 8" subs and the front and a 6.5" under to sofa. The front subs haven't been powered on in 6 months - I'll just get evicted.
