Who are some of elite sub woofers?

@jji666

they make vocals sound real.

You are crossing over way too high if you can hear vocals from your subwoofer.

It’s a subwoofer, impossible for it to have soundstage depth, unless talking stereo use with each sub playing either the left or right channel.

Rythmik, HSU, and PowerSoundAudio.

SVS if you are limited to BestBuy or want financing.

REL and Vandersteen don’t even come close to Rythmik and HSU in terms of bang for buck. JL Audio also isn’t as good for the money.

As for ported or sealed. Ported gives you louder output in the deep bass but cuts off below what it’s rated at, sealed gives you less output in the deep bass but extends deeper (meaning at 20Hz a ported may be louder but at 15Hz a sealed may be louder), transparent companies will post frequency graphs (all 4 I mentioned do).

Ported subs can be “looser” if they aren’t designed great (<$500 ones for instance, but that’s a budget constriction), high end ported subs are no less musical than ported, and they have less distortion usually as well.  
  
If you don’t have DSP/room correction nor tons of bass traps, I would go with sealed, as the room gain would help make that more neutral than ported speakers.

Crossing over? I just have subwoofers. I'm supposed to have other speakers? 
 

Uhh...your speakers?
