The day I brought home my new SVS-PB12+ sub-woofer from the store, my wife almost died.  The box it came in was approximately 3.5′ high by 4′ wide and deep.  “We could use it as a coffee table” was all she said.  Well, I cannot even begin to think about the WAF (wife approval factor) with this sub-woofer…

Big ass sub-woofer

 Royal Direct states the following about their low frequency behemoth:

“SUBWOOFER horns are built underneath the floor in a cavity of 1 meter deep. Each horn is driven by 8 x 18″ (47 cm) woofers. A total of 16 woofers. Each horn is 9.5 meters long and has a floor mouth area of 2.2 square meters and reproduce starting from 10 Hertz FULL POWER. The real mouth area IS NOT the one on the floor. The real mouth have to be considered together with the side vertical frontal panels. The total horn is calculated onto the listening point considering the side walls and the ceiling loadings. This reduces the floor mouth that is not in open air.  Total efficiency of the all AUDIO SYSTEM, not of the SUBWOOFER by itself)) is more than 110 dB/1 watt/1 meter.”

While I do consider myself something of a home theatre geek, this takes it to a whole new level…and I love it!  More information here
