I haven't been keeping tabs on the subwoofer situation recently, so I was surprised (and impressed) to see the wood finish box subs that SVS has recently introduced - looks stunning! I currently have an SVS PC+ 25-31 that I've been very happy with ... but since we're going through a remodel, thoughts of upgrading have been flitting through my mind The wife has never been crazy about the "garbage can" aspect of the PC+ cylinder sub, anyway ... admittedly, it has a certain appeal all its own, but not terribly high WAF The new box subs, however, look like they could be an excellent compromise since they're avail in quality finishes (in particular, it's interesting that they're offered in rosewood, to match the Rocket speakers!). My concern, naturally, is whether this would be worthwhile upgrade, audio-wise? I'm leaning towards the PB12 Ultra, but the dual-woofer PB12-Plus/2 is also intriguing. Would appreciate any info/suggestions, particularly from people who may have gone from SVS' cylinder to the box subs! The room size, btw, is approx 15'x20' (8' ceilings).
