I currently have a Goliath SWR III w/ workingman 2004 amp and use a passive fender. This is a great cabinet, especially when i had the passive bass and the aural enhancer made it sing. Next chapter in the saga: I recently purchased a warwick 2003 LTD FNA Jazzman. Sexy sexy bass. Problem is it seems to get buried in the mix (I play with two guitarist, one has a jcm 2000, other has a jcm 900 w/ 2 cabs) and in general i just don't like the sound of the goliath as much with the active bass. I've been testing out some of the more powerful amps for volume such as the 750x and sm900 thru the goliath and i like them, they're great amps and make it louder as expected. But I also tried the ampeg 810e and svt 4pro. This thing destroys the goliath in terms of volume and has a tone that i like more with my warwick. The power ratings of the ampeg are only 800 RMS though. Why is there such a large difference between my 700 rms goliath and the ampeg 800 rms? From what I understand of bass frequencies, more speakers means louder vs just increasing wattage. But there surely is more to this equation? Is SWR loose with their ratings and ampeg tight or is all this sheerly part of my imagination? In retrospect I probably should have tried 2 goliaths thru the sm900 but at the price it'd cost to get that i could just get the ampeg rig anyways... Your thoughts are welcome.
