I had Focal K2p's in my M3. Sounded great on the board but could not get any mid/low end out of them at all. Not a very full sounding speaker at all. I know it's all in application too, with our bikes and being that there isn't a lot of room or any type of enclosure, you'll need a driver that sounds good in open air. I've got 5.25 Rockford's in my bike, were in it when I bought it, and they don't sound all that bad for a 5.25". I'm in the same boat..looking for a 6.5" that's a budget speaker and going to sound good.

Granted, it's a bike. It's never going to sound like the 6.5" ZR series JL Audio's in my truck and I get that..so I can't see dropping $500+ on speakers. Not going to notice the difference of a high end speaker or a decent sounding $85 pair of coaxials going down the highway at 75. JL has a budget line..can't remember the name right now...it escapes me. But they're made by JL under a different name. I had a set in my last bike and they sounded pretty good..and weren't very expensive.

 

so what is a good $85.00 6 1/2 coaxial speaker?

 

Not sure on that..just throwing that out for a guesstimate meaning I wouldn't and am not gonna spend 500 bux on a set of high end components cause you're not going to notice/get the benefits as you would if they were in a vehicle other than a bike.

 

i disagree very much with not noticing the difference, because i notice a major difference between my bike and several other similar setups as far as power, but having less expensive highs... just telling the truth, based on my experience with having high end audio on my bike...

what i will say is that, you will get good sound, better than stock, by upgrading the speakers, so in that respect, most people are satisfied with way less expensive speakers... i normally get great deals on the stuff i buy, so the answer is very obvious to me... i am willing to pay the extra money to get what i want, when i am convinced that i want it...

with that said a pair of firecaps 6.5s are way less expensive than what i run, but they will sound good and be sufficient for what your goal is...

 

i have a 03 rkc and have one of those ebay windshield boxes but installed my own stereo,,, i bought polk audio marine rated speakers that fit 6.5" ,,, the awesome part is the tweeter pivots so sound can be focused at the rider,,,great sound 99 bucks at circuit city

 

I agree with you if the bike's parked...going down the highway at 65 with all the windnoise/engine nose you're not gonna hear SQ. But way better than stock yes!
