What sub under a grand?


Looking to replace my rel t1 which is having problems. My current setup is Parasound a21 amp and the Parasound p5 pre amp,Marantz sr 5007 avr and the Marantz sa8001 sacd. Main speakers Vienna Acoustics Mozart grand. 70% is for music and 30% movies, gaming and tv.

pulled the driver and amp off did not notice any obstruction or anything that looked unusual. I have the isolation feet coming in the mail we'll see if that works? my gut feeling is that it wont.either something is wrong with the sub or it just can't handle the low freq. think i'll be going with the psa sub not sure which model yet.
well the rel went back to the rattling when the frequency gets to low the t1 cant hang, its a wimp! so I went with the psa xs15se which has a 15 inch driver with a down firing driver and a 550 watt dsp. I would think in my room this sub will dig deep! and the customer support at psa is second to none, so far.i'll have the psa by tue so i'll keep everyone posted on how it performs.
Try a Monitor Audio Radius 390. It is one of the fastest sub's under 1 grand. In reviews people are very positive. The timing and control is awesome. It is fast as a rocket, with stunning looks!
