I need a subwoofer recomendation

Rel are good subs, but they are very clean sounding and may not have enough "grit" for home theater rumble.

Hsu might be okay, but be aware that those triangle ports have a lot of port noise.  This sounds like "chuffing" when the woofer moves a lot.

The SVS subs are nice, but I would say they have a particular sonic signature that is popular with the "consumer electronics home theater crowd".  It's sort of a larger-than-life type boomy of sound that a lot of consumers find attractive, but it is not necessarily accurate.  You may still like this sub, however.

For those who want the best sound quality for subs, I generally recommend Rythmik audio.  Ported subs have a meatier and grittier sound for home theater rumble effects.  Sealed subs sound too clean for me (almost like a bass sine wave), but many love them.  It's a personal preference.  The ported LV12F at $719 shipped is an excellent sub for home theater.  They have an accurate realistic response and do not have the port noise chuffing like the Hsu and other subs. 

Example of port noise chuffing on the Hsu:

Example of sound from Rythmik LVR12R (rear ported) using same soundtrack:

Hope this helps.

@auxinput What are you basing these assertions on?  I’ve never read any review that says SVS subs sound like this.  Further, I own an SB2000 and would not at all categorize them as “larger-than-life type boomy” sound. 

I  use two  HSU ULS-15 MK2`s, they are a sealed design and work great for music. Hard to beat for the money.

I also use a sealed Revel Ultima Sub-15 to play along with them.

I just searched for your Velodyne ad in the 4-sale section and could not find it.

Did you sell it already?

These are my own listening opinions when hearing SVS subs.  I would not say they are bad sounding, but they do have a unique tone.  I think the Rythmik are more accurate.
