How do SVS subwoofers compare to REL?

I'm looking for subwoofers (one or two) that have a very "tight" natural sound and are not overly boomy. In the future I hope to pair them with some Magnepan speakers. Magnepans are known for having a natural sound, and I want to compliment that.

I've been told that the REL subwoofers (e.g.,T/9i or S/3 SHO, etc., are a good match for Magnepan speakers. However, SVS subwoofers have also been recommended to me.

I don't have any background in high-end audio, so I am interested in opinions of folks here. Are SVS subwoofers considered generally as good as REL in regard to the features I'm interested in? Is either clearly superior? (I had never heard of SVS before yesterday.)

Which subwoofer size (in REL or SVS) would be a good match for a pair of Magnepan 1.7i in an 18 foot x 15 foot room (ceiling about 10 feet) with carpet on floor?

I'm looking at these so far:

REL T/9i Subwoofer about $1300
REL Acoustics S/3 SHO Subwoofer (Super High Output) about $2100
SVS SB-4000 13.5" 1200W about $1600
Any other recommendations?

Total subwoofer budget is around $2600 max. ($2000 or less would be better.)

Also, I believe it is better to buy two smaller subwoofers, compared to one larger one, right? (I'm just not sure where I would put two. Placing one is easier in this room. And I plan to connect everything with speaker wires, not wireless.)



If you thought the PC-2000 were too big, you'll be shocked by the Hsu, about 5.8 times the physical volume.

OK, I better get out my tape measure and do some careful planning. :-)

I see the enclosure dimensions for the Hsu are 24" H x 18" W x 26" D. That is pretty big -- about 11200 cubic inches of volume.

The PC-2000 are 34" (H) 16.6" (W) 16.6" (D) . It's the height of these that makes them imposing in my room. Although their volume is a bit smaller, they still actually take up around 9400 cubic inches of room space, in my opinion, being that rooms and furniture are generally angular.

Now that I realize this limitation, which are the smallest of the recommended subs?

The B&W PV1D is only 13.5" x 10.6" x 14.1". Is that the smallest of the highly recommended subs? I do believe I have room for two of those as long as they can be close to a wall or corner.

I will also look creatively to see if I have room for one VTF 15 MKII in a corner.

In-home trial until you can come to your own conclusion. Both companies you've mentioned will work with you on making sure you're getting what you want even if it isn't their product. I just sent back to SVS their SB-2000 in favor of an Hsu ULS-15 MK2 which was better in nearly every way minus size, but that size includes a 15" driver rather than a 12" that just plain moves more air. It was also producing much more defined, musical bass whereas the SVS seemed better for HT use. I would caution you on getting a sub with passive drivers (T7i/9i). Quality is not the goal in this design, the goal is get more out of a smaller enclosure. Happy hunting!

I recently purchased the new bowers and Wilkins DB3D sub. it is one of the most musical sub I have ever heard. It is fast and iron fisted tight.( 2 opposed 8” woofer with a 1K amp. It is absolutely seamless with my speakers. I know it wont get much love here as it is expensive. There are endless software adjustments with this sub. I believe its almost impossible not to get seamless integration with any speaker.
