sq amp selection

Briefly: 2 TC-1000 15" in a sealed enclosure. I want this to be a pure sq setup and now I am looking for an amp. I've browsed the forum and seen that audiobahn gets crapped on while mtx and others get a lot of praise. I am wondering why this is...audiobahn has comparable SNR, and a 24dB/oct roll off versus others that have 12. Don't you always want the highest roll off possible? Any advice on amps or how to select for sq would be greatly appreciated. On another note, do you guys advise using polyfil? If so where do you buy it?

Anybody know anything about the Kenwood KAC-X1R?

Numbers don't tell the whole story. S/N can be the same, but the amps will sound completely different. This is due to several differences: IMD, or intermodulation distortion, a spec RARELY supplied, and determines how badly a fundamental is damaged when a second fundamental (or even a harmonic) is introduced to the same signal path. Damping, or how well the amplifier damps (or shorts) the back-EMF generated by the voice coil. THD. Frequency response, linearity... Power supply capacity, a crappy power supply will not be able to keep up with the current demand, and this can be audible. (I might add that the power supply is ususally (or at least SHOULD be) the most expensive part of an amp. jville hit on it... SQ=MONEY! Slew rate, or how fast the amplifer's devices can turn on or off. There are other specifications that will come into play as well, but numbers (especially JUST S/N) will not tell the whole story. Oh...! And chrome (and flame facsimiles) is (are) ALWAYS damaging to an audio signal, this is why you should NEVER allow chrome, flames, and ESPECIALLY chrome flames near an amplifier... This includes speaker baskets, rims, bumpers, rear-view mirrors, etc...It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Dave, how  about the Alpine PDX-1.1000? It seems to meet all those criteria? Cough, cough......There is no such thing as free installation!

LOL Yep, it meets them all quite nicely!It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
