I have the Dayton DVC, the Titanic's little brother, with the 250 watt PE amp. The DVC is quite awesome, shakes my kidneys on medium volume. Also the DVC will play loud down to 15 Hz and still play down to 12. The DVC was playing down to 10 Hz but I shortened the port to tune it to 26 Hz to blend with my mains better. The Titanic is even better with the same amp; but it likes a bigger box. Hope this helps.
