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.)

Thanks

With SVS you have a 45 day in home return for full refund.
Thanks for the info. FYI, I don't tend to read private messages.

Also, thanks for the info about room modes & issues I might face in solving related issues. I do intend to get an Antimode 8033.

Using the SVS SB16-Ultra myself, but have no experience with REL. From what I’ve read of the latter they’re very musical subs, and integrate extremely well with the main speakers - depending of course also on ones ability to properly setup the sub - but all things being equal, and in that regard, I’ve heard mostly positive things on the REL’s.

As has been mentioned already though I do believe SVS is the better value in all aspects of the performance arc when considering the combination of integration, musicality, extension, sheer force, radiation area, ease of setup (with their new app), etc. There was a time, I gather, when REL was the go-to brand of subs if you sought the most successfully integrated, musical sub, but with the advancements in subwoofer development and technology these latest years I’d say you can have your cake and eat it too. And by that I mean they can be both very musical and immensely powerful as well - at a fair price, that is. REL, from what I can understand, somewhat lacks the second and third part here compared to other brands, like SVS.

Do you really need more power and radiation area, at the same price, than what a REL can provide? My opinion is that you can never have too much capacity, but you can overload a room with subs dialed in too hot, be they large or small. The more capacity you have however - all things being equal - the more ease, inherent power and proper fullness you have. Perhaps REL’s still have a smidgen of a lead in overall musicality and integration, I couldn’t say, but when you consider the other traits mentioned with a sub like SVS at a similar price, my bet would be for the latter to take home the price, so to speak.

JL Audio has also been mentioned, and they appear to be excellent subs. Still, these latest SVS models like the 16-Ultras and the new 4000-series I believe you’ll get an overall similar performance envelope, though at a much more reasonable price (sometimes even by factor 2). Another brand to consider would be Funk Audio (which I would favor over JL Audio), but prices may be too steep here.

My advice would be for you to invest in a single SVS SB-4000 to begin with, try it out thoroughly within the 45 day "trial period," and if you’re convinced of its merits I’d save up some extra coins and buy a second one at a later date. Buying two to begin with however I believe you’re granted a $200 discount, but that’s $3,000 to shell out at once.

I would have bought a second SB16-Ultra had space permitted, but sadly that’s not an option as is. Still it’s wonderfully capable being the lone brute (with velvet gloves) in my setup. Here’s the Stereophile review to give you an idea of the quality level and performance scope:
