Hi, I just bought 1 week ago a brand new alesis command drum kit and i have a P.A (15 inch speaker) and (10 inch tweeter) but when i plug the drum on it the bass drum and other drum sound are pretty bab, or is the command module is not good to play with speaker??? because on earphone is sound good or i really need to buy a pa for electronic drum like the vdrum amp from roland or the one alesis strike amp 12 or 8. because i think to buy there flagship drum kit the strike pro 11 piece but if is sound like the command when i plug on my p.a or we really need a specific P.A to have a good soun.
Thanks and i hope to find the good P.A
Depends on a number of things.. Freq range and frequency response.. on paper.. is not conclusive enough on it's own..
Look for drum amps that are specifically Voiced for drums in the 20Hz - 30kHz range...majority of PA,keyboard,guitar,bass amps etc aren't in that range and the ones manufacturers claim are doesn't mean they sound very good...headphones also.You'll find quite a few of those don't work well or color the sound.
Most of the newer drum amps will be in the 50Hz -20Khz range like the Alesis etc...and specifically voiced for drums.
