Summary:
This is a good sub for music only!!!! Do not try to use this sub in home theater applications in a relativly large room it really loses something w/ dvd. Yet when playing an audio cd it has good extension and sound. I have my db set to -20 when listening to music and -5 when listening to dvd and it still isn't loud. I thought it was my decoder but I believe the lack of a croosover really hurts the potential of the sub. It plays low, not real well but adequate for dvd but the higher more explosion type / gunshot bass is just not there. It may have something to do with a low crossover point but since it is not adjustable I can't tell. The soultion I'm getting another 10 or 12 inch sub to play with the solid. The solid has a low pass output to hook up to another sub (thank god). With two subs in the house I believe it will be up to par. Overall good musically but be warned about home theater.

Strengths:
Good for the size, very musical and smooth.

Weaknesses:
Do not get for home theater not enough output

Summary:
The PB100 comes from the little known Solid stable but claiming B&W design influence expertise. In fact everything about the PB100 from packaging to performance smacks of B&W and comparison of the specs of the latest B&W ASW offering, the ASW 500, shows they're identical.The PB100 is solidly made (no pun intended) and whilst sparse on features offers smooth, pleasant bass enhancement. Principle omissions are a signal dependent power supply (ie you have to switch it on or off or have it linked to an AC outlet on your amp). It also doesn't have a variable frequency cut-off filter. It has in line bypass filtering if you wish to drive effects speakers less bass output.
I have tried it with the Yamaha 995 receiver with x4 B&W 602 speakers for front & rear and a Jamo 100 centre speaker in a medium sized home living room with lots of sound deadening soft furnishings.
The sound is smooth, smooth, smooth and dovetails beautifully with the B&W mains and complements rather than detracts from music listening. In practice the bass cut-off of the the Yamaha receiver at 90Hz and its obvious compatibility with other B&W speakers makes a variable bass cut off filter redundant. To my suprise and delight I find I want to incorporate it when listening to non-effects audio such as classical, folk and non-heavy music.

From the earth shaking point of view it seems to deliver adequately on the Richter scale when planes, trains and miscellaneous aliens strut their stuff in the demolition stakes. It neatly delivers the punch in the bass rock line classics such as John Entwistle in My Generation or John McVies pulsating bass heartbeat in Fleetwood Mac's the dance DVD.

In conclusion I didn't set out to buy it, it was loaned by a kind HiFi dealer (DJL ELectronics of Caloundra, Qld) pending receipt of the ASW1000 (but at nearly a $AUS1000 difference) - but there's no way short of a direct hit in a Zeppelin raid that I'm going to part with it! Shortcomings ? well if your receiver is set up differently you might miss the variable cut-off filter and if you have an auditorium or need to dislodge next-doors ear wax you might need more than the rated 70W power, but for me it suits perfectly.

Summary:
There is really not much to say about this subwoofer, except that it's GREAT. For music use and/or for DVD with a Dolby Digital track. You have to hear Face Off on this thing to believe it ... amazing !

Summary:
