The room is 2100 cubic feet. Listening habits are 50/50 movies/music. I'm dazed and confused on this one. :frowning: Any feedback is appreciated.
From looking at specs alone, I'm not so sure that a PB2-ISD would have an advantage over the 2039 PC+ w/ the PB2-ISD port plugged to 20 HZ. The PC+ will still have all three ports firing and the ISD would be down to two. Both subs have about the same size amp (600 vs 525) but the ISD will lose a db or two once you drop the tune by plugging a port. It would be close for sure and in your size room it proably wouldn't matter.Hi Zack:
My post was lifted almost verbatim from Tom V., and I should have so stated initially to avoid conjecture.
I would have agreed with your reasoning and it's rock solid, but Tom has tested the two and says otherwise. Probably the coupling effect of the dual co-located woofers making up the difference.
With all ports open the PB2-ISD will lose out to the PC+ below about 22 Hz. But the advantage of the PB2-ISD over the PC+ above 22 Hz will then become even more significant, probably another 1.5 dB as you state.
