Are big subwoofers viable for 2 channel music?


In thinking about subwoofers to get for a large future listening space (30' x 30'). So far there seems to be a lot of great options for smaller subs for music.. such as the rel s812. Now my main focus will be music but I do plan to do some home theater on the system and I do enjoy subs that reach low and have strong but clear sub-bass. Would a large sealed sub still be able to provide clean tight bass that digs low and thus satisfy both duties. Can it ever match the speed and precision of a pair or more of rel 812s? Something like PSA S7201 or Captivator RS2?

A realize a smaller sub has a smaller moving mass and thus for a given level of power would be faster than a bigger sub with a bigger moving mass (driver mass). But a large sub would have to move less to achieve the same SPL and would reach lower.

Anyhow what do you guys think? Thanks.

Honestly I have thought of this same issue. I also have a large basement setup that is 95% two channel and 5% home theater. I have looked at large home theater subs (JTR captivator etc.) online and read up on them but almost no one uses them for two channel. I think they would be just as good for two channel but have no idea. I think there is very little crossover between the crazy custom HT crowd and the highend two channel crowd. I think you should let us know how it works lol.

Some subwoofer processing have multiple customizable EQ presents that can be set for HT and two channel as well as inputs for HT and two channel. While both systems can be connected only one system can be used at a time. 

I'm curious if anyone has tried having a multi-way sub array with several small subs throughout the room and one big one that only plays the lowest notes.  If you give a big sub a gradual rolloff starting at 30 or 35 hz it's less likely to have negative interactions with the room in the higher frequencies that tend to have the most problems.  Then add a bunch of smaller, cheaper subs that rolloff above 30 or 35hz.  It'd be a hassle but might get the most bang for the buck.  

I've got a tiny psb subseries 100 that sounds fantastic but has very limited dynamics and extension.  There's a used one on ebay for around $100.  I might be able to buy 10 small subs for not that much money.  Having a whole bunch would even out room response everywhere but the lowest bass.  The limited dynamics would be greatly improved by having a whole bunch of them.

@jon_5912  That is sort of like a rel six pack except you have different sizes and types of subs. I bet it would work well if it was properly setup.
