| Re: Single or Pair of 'X' for HT use? 4.4cuft with 2 4" flared ports tuned to 20hz looks good. Thats for each driver. So 8.8ft total. 350 watts is all you need for each driver in this set-up, and you should have solid output, 110db+, from 18hz up with the pair. The 2 4" flared ports on each 12, keep the vent air speed nice and low. |
