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.

There was a recent discussion about this in another thread where the OP was an owner of a Gotham V2 SW:

Here’s a link to a YT video featuring 2 line arrays of the baby brother in the REL performance lineup which is the 510 and an introduction to the REL philosophy by John Hunter REL CEO.

REL lineup goes

Reference series
1. REL 25 Reference
2. G1 v2

Performance series
3. 212se
4. 812se (replaced the S5 SHO which replaced the REL S5)
5. 510se (replaced the S3 SHO which replaced the REL S3)

T series

Be sure to listen to the part of the Demo @ 10:45. It’s a quite impressive demonstration of the REL’s ability to integrate with the main speakers.

I have a single S5 SHO which was recently replaced by the 812se. It’s a fantastic performer and I would say the value champion in the REL lineup is the 812se.

Based on my experience with REL, I’d think you’d be elated with the 2 channel performance and also quite satisfied with home theater as well.

I am thinking of 2x 2 stack of REL 812se for your room.
You can call REL directly and they will help you with recommendations.

Besides eliminating room nodes with multiple subs, you also want to integrate seamlessly with mains in both presentation and speed. Your mains will determine where you need to be in terms of sub-woofer sizing.

GLHF!
Hello smodtactical.

     There are many advantages to using 4 subs in what's called a distributed bass array (DBA) system.  Using 4 subs, that are each rated to have a capacity of outputting bass down to 20 Hz, results in no single sub being required to operate anywhere near its limit, the cumulative bass produced will effortlessly and accurately reproduce whatever the music or HT source content demands down to the deepest audible bass frequency of 20 Hz and the bass will be fast, smooth and detailed enough to seamlessly integrate with any pair of main speakers you choose to utilize. This high quality bass will also exist throughout your entire large room and not just at a single designated listening seat.
     You have the option of either creating a custom 4-sub DBA system with 4 subs of your choice or buying a complete 4-sub DBA system kit such as the Audio Kinesis Swarm system for $3K reviewed below by the Absolute Sound:

     Due to the large size of your future room and your desire for high quality deep bass performance, I suggest you utilize a minimum of 2 good quality subs, if you're mainly concerned with high quality bass performance at a single designated listening position and 4 good quality subs if you prefer even higher quality bass performance throughout your entire room.

Best wishes,

OP must have missed the very first post. Tim and I are on the same page. In fact we have almost identical subs. https://systems.audiogon.com/systems/8367 Main difference is I built mine, with help from him and Duke, while he bought Duke's Swarm. Also I have an additional 5th sub, the Talon Roc. Which is how I know the more the better.

Like the first post said, its not a question of which, its how many, and the more the better. 

Subs in a system are like horsepower in a car- more is always better.
