I think for image, anymore than two speakers up front will only degrade. it's hard enough to get two right . . . the car is a horrible acoustic environment, so i think speaker placement becomes even more critical, which is tough because there are usually very limited choices. i got pods which moved my JL650VR from the doors to my feet. made nearly as much improvement to overall sound, as going to the CD90/4000x from a clarion/kenwood eq. although the previous post does peek my ears about raising the soundstage with some small rear fill. i finally got a nice tight image but soundstage is right at the steering wheel. i figured to tackle that one with custom enclosures on my next ride. does anyone separate their mids/tweeters up front more than 6", and then adjust with the 4000? i've thought about trying it but worry about phasing. > > Center Channel?? only if i was doing theater in the car. personally, if i want mobile DVD i'd get a portable. more versatile. -- Scott Walters -PacketPusher ________________________________ Message 2 _____________________________________ Time: 05:23:24 PM PST US From: NOTGSXR@aol.com Subject: Re: XDP4000X-List: Center Channels and Rear Fill. --> XDP4000X-List message posted by: NOTGSXR@aol.com In a message dated 12/29/02 3:37:30 PM Eastern Standard Time, scott@packetpushers.com writes: > does anyone separate their mids/tweeters up front more than 6", and then > adjust with the 4000? i've thought about trying it but worry about > phasing. > As it stands now, my 4's and tweets are about 15" apart.... I havn't had that much time really with a laptop to play yet.... But what i did find is that you should have some overlap with the frequencies they are x'd over and the slope needs to be no more than 24db/oct... ( alot of this depends on speakers used as well). Something i really wish i could get a list of is the Available frequencies for the A, B, C, and D outputs.... since i got my unit 2nd hand, i am not sure i am getting all the available options. As far as my midbass, i find it hard to believe that 500hz down is the lowest i can cross over the top side.... i would like this to be no more than 300hz, and ideally 200-250 range.... and allow my midranges to take over from around 200 and up..... As far as worrying about proper phasing etc, its best to temporarilly place the speakers and listen...... do it for a week, 2 weeks.... (also play with the 4k to try to get the best sound also when you move it) and then do it again till you find the permanent place. Trial and error will always yield better results in my opinion. Every car is different and as you said, they are not ideal acoustic environments so this may take some time, but i am sure you can come up with something that suits your needs very well :) Don't be afraid to play :) hope that helps... And please, someone give me a list of all available frequencies to Xover at!!!! Thx Dan
