HSL make sum bada$$ subs. The eXcursion pro is great!!!
The DVC is rated at 600RMS and in the right box with, even severly underpowered, like 100RMS
I would personally rate these among others as one of the best (budget) SPL subs - at times when I hear one I compare it to..........
Hurricane Powerstroke
Planet Audio Vector D's
Treo
DD
Shockers
Strokers
Memphis SHP's
Beyond Audio
Whilst it probbaly wont hit the SPL levels these monsters can, its price and the fact it bumps of v.low wattage, makes it a sure winner in my books. One to put alongside the ones I mentioned, i think - v.good sub!!!!
Give any of the above 100RMS and put it against an eXcursion pro in a good box and youll never buy anything else.
