I am considering installing a pair of these in my rear seating riser, DLS HOME AUDIO-INFLOOR SUBWOOFERS #300-445 from WWW.PARTSEXPRESS.COM I really want some significant BOOOOM in the room. In addition I will be using three pair (six total) AURA PRO SHAKERS in my Berkline CinemaSeries seating, along with a VELODYNE 1200 sub....which I may upgrade to a SVS subwoofer soon. These look rather unique and would be easy to install as I have not yet carpeted my riser project. The INFLOOR subs ($100) plus a 125w Sub Plate amp ($80) sounds like good deal for a speciality sub unit that would blend seamlessly into my dedicated HT. What do you think? Are these quality drivers? Specs seem to be fair enough. Any advice aprreciated!
