I feel directing a fart through a concrete pipe is a better option than a BOSE system.
I mean, let's INJECT deliberate phase issues into as few drivers as possible. Aweful stuff. I'd call it crap, but it's just a compliment. They've managed to make SINGLE small speakers with the entire sytem out of phase with itself by DESIGN. WTF? We're talking about deliberate efforts to screw things up from the get go, sort of a "well, if you've done everything good up until the output stage and you want to f*ck it up with your final set of transducers, then we gots the product for ya right here".
Bose speakers are some of the most over-hyped and over-marketted trash on the planet. Quality? Oh sh*t no, there ain't none of that in any product they've ever made, at least not that I cant tell.
I'm also not saying a DJ needs to get the best speakers, but to then whatever they choose to use, play COMPRIMISED AUDIO, well, you're just saying "I don't give a damn" from the get-go.
Garbage in=garbage out.
I mean, for $300, you can get a certain Behringer unit that has RTA functionality in it. Hit your system with some pink noise, sniff it out and correct to the room. Instant improvement, especially if you're using cross-over. Or, even better, for a little bit more, use an affordable dBx Driverack system processor. Sure, maybe you can't spend $4k per cab like I did, but you can still maximize the stuff you do have with some well thought out purchases. But if in the end you just want to push crap through it, well, at least your crap will sound more like the crap that it is, instead of just crap pouring through a crap filter into a craphole.(that, just for the record, would be a BAD thing).
But hey, I hear ya. Buy crap, expect top dollar. Why put in the effort for quality when frankly, at least around where I live, nobody gives a flying load of crap. They want cheap, and damn the rest. And then they get what they pay for: crap. So, when you don't care enough to do the very least, we see and hear and suffer as a result.
But, at the very least you can do is provide the best SOURCE material you can. If you can do THAT, there's a LOT of other things you can do for FREE to improve your sound. Well, maybe not FREE, but you can control your costs better. Multiple amps, subwoofer, cross-over and/or RTA and/or system processor(could replace a system EQ, RTA and more).
Then again, maybe I'm just too old school after dealing with A-listers and their tours for like 20 years. I'm paid to BRING the best, USE the best and DO my best, and anything LESS means I'm out on my ass.
So, unless you're going to do the best with what you've got, then yes, you're cheating everyone, INCLUDING yourself. You can't IMPROVE a crappy source, and it's only going to go down rapidly from there as each weak link will only help increase the amount of this problem.
One last slam on BOSE:
It stands for:
Bring Other Sound Equipment.
I won't work at a place that carries Bose. I can't stand behind it except to press the detonator on the explosive I strapped to it. A local Guitar Center wants me, but I can't take the job because I gotta sell BOSE(not mandatory), but I can't say anything positive about any of their products ever made outside of "I sure am proud to say I can't stand BOSE products".
So, my point is, clearly, many DJ's don't give a crap, and it shows, and it shows really bad. I guess it's more about money than caring about quality. For me, it's quality first, money second(maybe 3rd, 4th or 5th, money is never my top priority). I can do fantastic things with cheap gear as long as my source is good. Without GOOD quality soure(and MP3's ain't it ever), you got nothing.
But I also won't do DJ work. Not that I won't stoop to that level, but in part because I won't. It's mainly because I don't know what people want and most pop tunes are poop tunes and they make my bowels want to explode in an effort of self preservation. I'm an audio engineer and I mix bands, that's what I do.
