Comments from Pimster:
A great sound even with a provisional crossover at 150 and 2500Hz. Tight bass, mid and high are silky smooth
with hard paper cones (SB Acoustics) and ceramic tweeter (Visaton). Good detail, but not yet as Seas Excel.
It will get a bit better once it has played more suppose.
The Coolbacks are playing great, with one already modified: no resistors (back to standard). The other one
follows this afternoon. I must admit the modified one (according to your recipe) sounds really crispy. The
Coolback II 300 does not mind low impedance at all!!
I like this kind of modern/fusion etc. Bob James, Pat Metheny. But also I like classical, Mozart and piano
(esp. Chopin). Also small classical, which we attend often “live”. Later I will try Edvard Grieg Peer Gynt,
Hall of the Mountain King, a real test for the “dynamics” of all speakers!
Hi Robert, by now they are both modified (without the resistors and the units in parallel) and all is working
properly. The sound is really nice, smooth and dynamic at the same time, even without measurement.
I have only compensated for two room modes, a mild surround resonance of the mids and the difference in gain
of the different amps. The power supply has more than enough steam for the two PA3CC and the PA1CC. I did not
hear distortion even at higher level (and the two SW182 4ohm in parallel should not be easy to drive..!) The
room is about 50sq meter.
Okay, I’ve driven them very loud for some time now. Great sound and tight bass at nearly 2Ohm!!
I just enjoy listening (Miles Davis for now!!) Great sound!
