All in all it's not just another brick in the wall;-) Yes with the New Needle WandTL, you won't make the walls vibrate! But with our BB3.5 broadband, the New Needle plays pure WandTL, without a lock circle, just about everyone else on the wall! It was not for nothing that the hobby HiFi Heft 4/2016 was: The BB3.5 by Omnes Audio impresses with excellent acoustic qualities! A sound pressure speed rate up to 20 kHz, which is almost perfectly linear, a good efficiency and the low climate factor level characterize this speaker. So then have fun with Pink Floyd and hey Teacher, leave us kids alone!
