A brand new product from Sunfire that I've used 6 of are the HRS series subs. Stunning, given their price point. After using these we probably won't be going with any other entry level subwoofer that either doesn't come in a pre-built 5.1 package (YUK!) or that we can buy in bulk to offer a huge discount below what these go for. This is just my opinion gathered from personal & professional experience, but I don't know if I've ever heard anything that comes close to these little subs in the price category of $1K and down. You want to go up in $ another couple of hundred to say a $1500 piece, sure there are things that are better performers, but under that I think the HRS line holds it's own, easily.
The HRS line, to me, is INCREDIBLE for the money. They absolutely pound & without being muddy or sacrificing. The finish is a really nice piano black and these subs are absolutely tiny, having no right to sound so big. If you can audition, go try one out. I have not used the HRS-8 (the 8" in the line) but the HRS-10 (10") & HRS-12 (12") were both great and I would expect the HRS-8 to follow suit.
A great example of a WOW moment was our first time using the HRS-10: Client had a fairly large basement (60" plasma but PLENTY of room to have done a front projection system in a wide open room) and we demo'd the movie 300 as his first "experience" with the new system. We used 1 HRS-10 and had the volume @ a level just under the "no more" thresh hold. That single HRS-10 destroyed us. Deep, clean, tight, and detailed. Fast starts & stops and, most important (to me), NO waffling/chuffing. That's tough for any sub, save for the higher end, to really pull off @ high volume levels and in such a big open space. We never once heard the sub... we just felt it. That's when I knew it was a great piece.
@ the end of this week I will be done with a system that uses two of the HRS-10's & will post photos (along with the Sunfire Trio pics that I need to put up.... we just aren't done with that project yet).
