Xover points will also be slightly different.

so other than more midbass nothing that much difference? what do you guys think? should i go ahead and try to make the 6.5 fit? or no?

If the mounting depth is OK, you can usually fit a 6.5 in a 5.25 spot with a little know-how and MDF or fiberglass.

If it's in doors, some cars, like mine, had metal brackets that you could take off, mount the speaker in the bracket, and the mount the entire thing on the door. In that case, just fashion new brackets and it works perfect. Did for me. =)

beaming effects increase as cone area increases.

Beaming has to do with degredation of off axis response.

Head to SIn and a couple of quick searches will tell You more. Pay attn to the posts by Wiggins.

can you guys explain this beaming thing a lil more it's really confusing? im still debating about the 6.5 or 5.25.

id go about it with room considerations than anything else. if you can set up a 5.25" right it will outperform by a large margin a 6.5" slapped in the doors. ever go to elitecaraudio.com forums look for c music he had a car back in the day with a 4" (boston pro 4" component set) as his entire front stage and he beat up alot of guys with 6.5's and 8's lol. its all in how you set it up. he is an iasca judge now pretty cool guy. didnt sound like a 4" and in my truck im selling a 3 way comp set to go with 5.25"'s in my kicks because it leaves me more room to tune them in

Are there any pics of the install you know of? Trying to find some info on "c music"(?) ride?

It's basically exactly like Nick said. When the soundwave of the frequency is smaller than the size of the cone, the speaker's dispersion will narrow and the speaker will begin to "beam" (really poor off-axis response). Think of it like a flashlight, with it's focused beam of light. As you start to increase in frequency, a speakers dispersion will begin to narrow like the beam of a flashlight.

There is your non-technical definition :p:

small drivers tend to have less of a beaming effect.

Thats the easiest way to explain it. :p: LOL

he is all over the elite forums and in car sound some. im sure i had pics at one time but the pics wont really "tell" you a whole lot. knowing chuck like i do he would gladly talk about it. i know he did with me at the iasca shows.

wait so your saying thats why tweeters have are more sensitive to position right?

oaky... umm dusnt that like contradict sqeaks comment?

Remember what I said about it's relationship to the size of the driver ;) The smaller the driver, the higher the frequency will have to be before beaming becomes a problem. With the small size of tweeters, you have to get very high into the frequency range for beaming to become a problem. I'd be more concerned (beaming wise) with playing a 6.5" too high than I would about the beaming of the tweeter.

oh okay, so when running a 2 way comp set, its like this:

6.5 for the lower frequencies

and 5.25 for easier aiming?

kinda like a tradeoff.
