I don't know why you folks think the X's won't perform at the levels he is asking for... In my case, i too thought the R's tweeter sound like s hit, but they did get loud. If you want JUST loudness you could go with the R's for cheaper, but if you want to throw some sick SQ into the mix you should go with the X's. They can be had for around ~$200 shipped since new models are coming out in summer. Personally, having both sets i think the X's would suit you all around much better regardless of your likings. They are very versatile, and like i said doing a proper install, 99% says you will be quite satisfied.
Btw, i'm not biased just because i have the X's currently, i have had both sets of comps and completely understand their are 34296234698 billion other comp sets that would suit your needs too. It's just that you said you were a dealer, and brought this set up, so i'm just giving my $.02. Let us know what you are thinking currently, and we'll try to help steer you in the direction you prefer.
