Best Subwoofer To Use With A Two Way Speaker System

I own the least expensive 12" sealed subwoofer made by SVS--the SB 1000 (just 1...not enough room for 2). It cost ~$500 + shipping. The sound is excellent in every way: powerful, deep, impactful, tuneful bass (sealed is obviously the way to go for music listening). This sub is quite a bargain.

The same basic sub but with more max output power (500W vs 300W) is available as the SB 2000. It's a big bigger and said to put out a lot of powerful bass. Neither the SB 1000 nor SB 2000 have room correction software. You have to adjust them by ear--old school (fine with me).

As you go up SVS' line, subs get bigger & far more powerful in the Ultra models. The 13" ultra has 1000W, DSP sound contouring, and costs ~$1,600 each. The 16" ultra, their newest model, has been getting a lot of attention in audio circles. It has app-controlled room correction software said to be very effective. Power is 1,500W and it costs ~2000 each. This unit has been compared to audiophile subs costing 2-5X as much, and it is said to be more than competitive.

If I had a big living system & needed subs, I wouldn't hesitate to get a couple SB 1000's or SB 2000's. You get great sound at bargain prices.

I have the Wilson Benesch Arcs and I pair them with a REL Strata III, picked up on CL for $400. Great combo, easy to dial in, and they blend together well so the REL isn't intrusive.  Sounds like I have floorstanders instead of monitors, but without overpowering the room.

I'm using a JL Audio E110 sub with the 2 way Lawrence Violin SE speakers. My Primaluna Int amp has only a mono sub output but it is more than enough in my 13 x 18 room. Since the speakers go down to 38hz, my dealer suggested I run the speakers at full range and crossover the sub at 45Hz. Both the speakers and subs are about 48" from the front wall. I was told to invert the speaker wire and adjust the phase on the sub until there was a null in the bass. I switched the speaker wires back to normal and then adjusted the volume on the sub to where it can't be hardly heard and doesn't overwhelm the sound of the speakers. As a result the bass is tight and no boom. If your room is larger you might consider the E112 or 2 E110.

Ive had very good luck with REL.  A pair of Subs has worked far better than one.

I have a pair of REL Strata IIIS with Decapos. Agree with Chlv0ter, adding a 2nd sub was as significant as adding the 1st one and not just for bass performance but overall smoothness, dynamics and clarity, just more musically convincing. These RELS integrate so seamlessly, they never impose as I have heard with other sub systems.
