So, I decided to run a little experiment with the basement system with left over equipment I have accumulated over the years.
This discussion is for the sub system only. I have an Onkyo m282- rated at 125w RMS @ 6 ohm...not rated at 4 ohm per the manufacturer.
This amp is powering 2 poineer premier ts-w120c subs (12" 150 rms @ 4 ohm) in an enclosure that I built. I modeled the enclosure after my Velodyne DPS 12. The basement is approximately 20x30. The only thing I have not done to the box is to fill it with polyfill. Pioneer recommends 1.4 cu ft per sub in a ported atmosphere. The box I built is approx 1.5 cu ft per chamber. Using a tuning program ala winisd, I tuned the box to 31hz after requesting the spec sheet from pioneer.
The problem: When I get close to the sub enclosure, it is obvious that it is putting out deep, clear bass. The aspect that I am not satisfied with is how the subs fill the basement space. You can notice a difference in that deep bass has been added, but it does not hit(and fill the space) the way my Velodyne does in my 13x20 living room. What can I do to rectify this problem? Bigger amp, different enclosure, or both?
My intuition tells me that I need higher powered subs and a higher powered amp to fill the space, but I have sentimental memories of these subs and want to make them work.....opinions??? advice???
Thanks in advance.
