What sub under a grand?

Well the one thing iv'e learned about this hobby is no matter what you buy you're wrong in someone's eye's. this sub will be part of a ht setup as well, and what iv'e found is the small fast subs cannot handle the low freq of movies or gaming threw the ps4 without breaking up and rattling.when I game or watch movies i want the bass to be thunderous,when i listen to the red hot chili peppers i want fleas bass to thump my chest, the smaller subs don't that. i will always go for the v8 over the 4 cylinder.

It depends were you use it for, but these sub's are not that fast. I demo and compare subwoofers for timing and integration. On the other hand I want to use them till at least 120 hz. With Audyssey you can easily get a very good level of integration with a subwoofer. Above 80hz low freq. become physical. Beside this you get a more deep stage as well. In the pastI sold many rel subwoofers. We never went further than 70hz. These days some subwoofers use material and magnets so you can use them easily till 120hz or even higher. In all my tests this makes a big positive difference.

Well all I can say my rel t1 is a pooch! I have it set so low in order to avoid an extreme rattle a may as well not have it on, in fact i just turn it off while playing call of duty, watching movies and even with tv. so what good is this fast sub? with music it's ok, and that's all it is. i think the psa will be fine, if not i have a 30 day in home trial shipping free both way's. so what's to lose? do I think there are better subs? of course! am I going to pay 1500 +? nope! and this this t1 would fall apart at 120hz.

Claiming a "big positive difference" from using a sub for higher frequencies than around 50 to 60hz requires further explanation, and I hope there isn't anything of the sort forthcoming from the strange paragon of self parody that is Bo.

Yeah i'm not sure what you mean bo? But imo I think music should not only be heard but it should be felt. The best live concert I ever saw was in cedar rapids Iowa and the band was Tool 10,000 days tour,I was setting in the upper bowl straight back of the stage the bass response in this auditorium is unreal thumps your chest and rattles your seat, don't worry I could hear the pings and tings as well.my point is without this thunderous bass the concert would have been blah! this auditorium didn't use subs and amps that were just enough! they have more power and bigger drivers than what they need,just like most of our home setups.my main amp is way more than what I need my main speakers are more than what I need so why should my sub be less?
