How much of a difference?

They are both great subs but I believe the VTF will dig a little deeper and give you more tuning options.

How about the Epik Legend?

The Empire would not sure about the Legend.

The only thing i can compare my Epik Empire to was my preveious duel Klipsch RW-12d's, and it dominated both of them, so i would think the Epik Legend would be great also.

If you've got the upgrade fever it likely won't stop with a mid level offering. Both of the subs you mentioned would be noticably better than the BIC PL-200, and will tide you over till you hear better. :P

Either of those subs would be a huge upgrade. Check out this chart and compare the Bic to the Outlaw (the HSU would be comparable to the Outlaw). It is not even close. At 20hz, the Outlaw is up 20Hz!

save up and get a SubMersive! that stopped my addiction........I think it would stop yours as well.

There's no love for other brands here. Just Internet direct. Nothing wrong at all with them (they're great!), there's just others out there.

Try velodyne DD plus, and JL fathom!

Its not that there is no love for them its just for the money they charge you can match or beat them for less money.

Umm.. You do realize the OP is talking about $600 subs here, right?

The DD+ series of subs start at $2800 and goes up to $4800........

Ummmm......he's an addict.....as he himself stated. His addiction won't stop till it's fed....properly! IMHO a Seaton would be a junkies finest score.

Keep saving and stop wasting.

I would just grab the hsu vtf3-4 and call it a day. I had the 3-3 version and it was plenty for my 3300 cu ft room. I sold it and grabbed the VTF-15. Don't beat yourself up, this will be a huge upgrade over the Infinity and Bic subs. I have a Bic H100 in my bedroom and that thing wouldn't even be an appetizer for the 3-3. It will put a grin on you like nothing else. Plus with all those tuning options you can tinker for the next several months. What else is there to do in life but work, tinker, and enjoy your home theater?

Let me/us know on which way you decide.

Eat good food, drink good booze and have sex. Not necessarily in that order.

This ^^^ I also went with the VTF-15H one of the best decisions I made in my HT purchases and would do it again for the money its just hard to beat.

you cant go wrong with either one. Designed by the same person.

I believe the HSU has more tuning options, and well, it is in stock

I think that sub would be a great fit for an addict in that size room. seriously. its not too much. its a great choice. that or a svs pb12-nsd.

Just a note, not sure what your electronics are, but my VTF3-3 in a ~4000 room just barely cracks the volume pot and is still at -10 on an Audyssey setup. So if you have Audyssey and normally efficient speakers, be ready to rinse and repeat if you set it too high to start. Umm, that's with one plugged if it matters.

I think he meant start out with low settings a little goes a long way I know the instructions say the sub gain set at 9 o'clock and then the AVR should be around -3 or 4 so as not to be over bearing I ended up somewhere between 8;30 and 8;45 on the gain.
If I ran it at 9 the AVR had to be set at -7.5 which will still get you there but it may take a strong bass scene to wake the sub if set to auto on.

Mostly just don't set it too high to start like he said above. Audyssey people like to say to start half way or something, but on mine that might as well be infinity - I never get close. I have it in a front corner, so that might be part of it, and maybe Hsu made a running change to get a more refined volume control or reduce the gain (mine is a few years old.)

Just saying - I don't see people talking about this with Hsu subs, but a lot of people run their subs way too high, so they wouldn't know there was a problem. Side note, my calibrator was here a few weeks ago, he also does Audyssey Pro audio cals, and he laughingly said that what he mostly hears is turn up the surrounds and turn up the sub!

Just for the record, I love Hsu subs (Dr. Hsu was the first person to tell me how to put an addy in a browser - I was using a library computer, on the phone with him, and he kept saying "just type it in" and I kept saying, "type what and where?" It was pretty funny, he was so patient and kind and we finally figured it out If I ever do another system upgrade, the sub is one thing I won't half to think about.

I don't think there's such a thing as too much sub... there's a volume knob for that. Too little sub... that is definitely real. No easy button for that...
