I'd still like to know how Danny "brought the low end down" on these speakers without using an inductor with significant DCR. That info is not in his video.
If you can explain that one to me (without speculating) it would be appreciated.

Dave,
If you look at the plots, the 1.7 bass is down by @ 3dB @ 200Hz and @ 5dB @ 300Hz, but the rolloff at 65Hz is still @ 2.5KHz suggesting the bass panel's slope rolloff is shallower after the mod.
Is it possible he also changed the bass panel's XO ?
Tim, in the video DR states he left the bass/midrange driver filter slope stock. A call to him may answer every question one has.
Like everyone else here, I know only what's in the video. Anyone who buys DR's mod kit for the 1.6 and 1.7 will get a pair inductors, and be free to provide it's value to any interested party, assuming DR doesn't remove any value designation on the part, as do many other modifiers. For that same reason, a call to DR asking for that value may have his request denied. ;-)
