I keep thinking I am going to try this to satify my own curiosity. I talk so much shit about PA drivers that I want to get some cheap ones and try to get them to sound good. No way I can do super tweeters though.
Maybe just some cheap, cheap mids.
I beg to differ.
Even untrained listeners could pick out small details from one driver to the next. Besides source unit/processing, drivers are the most important piece of the puzzle. Of course.... crap drivers in a good install would robably trump great ones in a crap install though.
Like Sundownz said, there is a very small, yet very expensive jump from say.... $600-700 comps to $2.5k comps. But a huge leap from $200 to $700. We could definitely hear the latter, but would struggle with the former. But SQ is much like SPL. Top guys can add another $2,000 amp for a few tenths of a gain.
I have about $1k (used) into my front stage. And I think it's pretty freaking awesome. I sat in a couple world championship SQ vehicles at finals and they were unbelievable. But they have probably $10k into their shit. Is the difference worth $9k? Not to me.
