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.

twoleftears,

    You can do this with the AK Swarm and Debra DBA passive subs, front firing but terminals on the bottom and controls on the amp/control unit.member hleeid has a Swarm in his small office with 1 sub on the floor and 3 on shelves near the ceiling and firing toward it. He’s stated it saved a lot of floor space and sounds very good.  He posted fairly recently on this thread.

@oldhvymec: Why is the rule of thumb, 2 to 1 with a Passive radiator, system? Not so. 4 12s and 1 15" active, can be tuned with a single 15 passive.
Just need a larger enclosure, that's the problem enclosures are 
way too small, and way too short.  Big BASS big enclosure.. about
a ton or so will do..4 500 pounders rubber lined. Yea...

Not sure what you mean but my little 12" kills my 15/15 passive in every way. I'm guessing its the much newer technology.

I'm saying 4 ea 12" active drivers,  and 1 15" active driver, can be tuned with a single 15" passive radiator, without over excursion of the passive. The reason, column can have a much larger volume, like 8-12 cf. or more.  It's easier to tune to a given room, and the roll off is much quicker mechanically. It's much more controlled, like an infinite baffle, but can go very low, without the ever present noise from ports.

Columns are just better, but they are not usually partner pleasers and they cost more to build, The units I've seen and built can be very heavy, 3-500 lbs. BUT you get what you pay for, when it comes to bass.

Just because there is a lot of it, and it's everywhere, doesn't qualify it as good bass. I've heard a lot of that over the last couple of years, now all of a sudden it's the big craze. walk on subs through a room. LOL

What I don't see is the blending, between low mids, MB, Bass and Sub
ALL are very important to address, not just squat and grunt out a sub/bass unit,  like a pile of dung.. Geezzz. That's "a way" though.. for sure..
