Yes, you'll need an amplifier. For an adequate subwoofer amplifier of that size, you'll probably be looking at a Class-D type.
Help with inwall sub amp
Hello! I need your collective help with a small room sub. In the room today I have a Bluesound Power Node connected to some in-ceiling Bowers and Wilkins CCW 7.3 speakers. Overall the sound is good, but I wish the base was a bit nicer.
So I was going to add the B&W ISW-6 in-wall sub. This is a passive sub, but I'm being advised that it needs it's own amp....
1) Does it?
2) If it does, what's the smallest footprint amp I can find for it? Something around the size of the Power Node would be best...the B&W solution is a rack mounted amp. Here's a photo of the current audio stand - a cocktail table that nicely fits the Power Node. Trying to maintain this type of profile.
Thanks for your help!
