I just purchased one of these for £200 and to say I'm impressed is an understatement.

Does anyone here know how they managed to get that bottom end out of two 3.5" drivers? I've measured useful response down to 35Hz and the quality is amazing within the units volume limits. No bass port chuffing...just incredibly linear.

All I can find on the web is they use long excursion 'Atlas' woofers. There is a serious port on the rear but I cant gind any published envlosure 3D cutaways.

It's really made me wonder where small active speakers + Class-D + DSP designs are heading.

I wish JBL would let the same designers loose on a £3k active home system as they are obviously into some serious R&D.
