Looking at the Quilter MicroPro 200-8 that's equpped with a Celestion TF0818 & wondering how it can hang with acoustic drums in a loud rock band. The speaker is rated at 100 watts with a 94dB rating, which seems really inefficient compared to most guitar-centric speakers rated anywhere from 98-102. Wouldn't this inefficiency 'de-rate' the amp's 100 watt output ? Or is the amp rated at 100 watts despite this inefficiency ? I'm guessing the latter, but just wanna make sure I'm not missing anything here. Also, the frequency response of the TF0818 is listed as 70-6000Hz. Would this slightly wider-than-average range compensate for it's size as compared to a 10"/12" with regard to low end ? I also read that this speaker has a dispersion of 130 degrees - is that a result of this extended frequency range ? Lastly, if one of these Celestion speakers doesn't do the trick, would adding an extension cab with another TF0818 make up the difference ?
