I wrote Aguilar to get some more info on the specs for the GS410 cab. I was IMPRESSED because I sent the email late Friday afternoon and had an answer the next morning from PJ LaMariana at Aguilar. I'm not surprised because that's the same kind of first-rate communication that Roger Sadowsky offers. I do rank Aguilar up with Sadowsky. It doesn't get a whole lot better in my mind. Well for my question since I forgot to ask this. Does anyone know if there is a peak rating on the Aguilar 4x10" cabs? I know that the cab is rated at 700 watts so it shouldn't pose any problems running my WT-800 bridged into it. I did find out that the sensitivity is listed at 104 dB and PJ says that this is measured at 1w/1m. I also asked about the +/- dBs is for the frequency response. PJ says that it's +/- 2 dBs at the 40Hz to 16kHz and that at 31Hz it is down around -4. This is real respectable. If anyone has one of these cabs please drop me an email because I have a few other questions. Thanks!
