A simple tweek to transform the pw2200
I had the pw2200 in a large (20 x 25 x 10 ft high room, in a house) as an inexpensive attempt to extend the response and reduce the wear on the drivers of Platinum Audio Quattros driven by a Bryston 4b. The Quattros are such an excellent speaker that effect of the pw2200 wasn't all that profound. Then I happened to call an engineer at TC Sounds and got a fine recommendation for an alternate driver based on the enclosure dimensions and amp specs.
For a fairly modest investment, and 15 mins with a sabre saw and power screwdriver, this better (tc3hp) driver with more than 2 inch linear excursion and 30 lb magnet structure makes the pw2200 something entirely different including about 50% heavier. All of a sudden, extremely low frequency information is revealed on certain recordings that "just . . wasn't . . there" with the Paradigm driver, all the while retaining the musicality to 80hz where I'm crossing at. OK, you have to shim the grill out another inch as well.
This sub is now worth keeping for a while
