The complete XDP4000X-List FAQ including these Usage Guidelines can be found at the following URL: http://www.matronics.com/FAQs/XDP4000X-List.FAQ.html Thank you, Matt Dralle Matronics Email List Administrator ****************************************************************************** XDP4000X-List Usage Guidelines ****************************************************************************** The following details the official Usage Guidelines for the XDP4000X-List. You are encouraged to read it carefully, and to abide by the rules therein. Failure to use the XDP4000X-List in the manner described below may result in the removal of the subscribers from the List. XDP4000X-List Policy Statement The purpose of the XDP4000X-List is to provide a forum of discussion for things related to this particular discussion group. The List's goals are to serve as an information resource to its members; to deliver high-quality content; to provide moral support; to foster camaraderie among its members; and to support safe operation. Reaching these goals requires the participation and cooperation of each and every member of the List. To this end, the following guidelines have been established: - Please keep all posts related to the List at some level. Do not submit posts concerning computer viruses, urban legends, random humor, long lost buddies' phone numbers, etc. etc. - THINK carefully before you write. Ask yourself if your post will be relevant to everyone. If you have to wonder about that, DON'T send it. - Remember that your post will be included for posterity in an archive that is growing in size at an extraordinary rate. Try to be concise and terse in your posts. Avoid overly wordy and lengthy posts and responses. - Keep your signature brief. Please include your name, email address, aircraft type/tail number, and geographic location. A short line about where you are in the building process is also nice. Avoid bulky signatures with character graphics; they consume unnecessary space in the archive. - DON'T post requests to the List for information when that info is easily obtainable from other widely available sources. Consult the web page or FAQ first. - If you want to respond to a post, DO keep the "Subject:" line of your response the same as that of the original post. This makes it easy to find threads in the archive. - When responding, NEVER quote the *entire* original post in your response. DO use lines from the original post to help "tune in" the reader to the topic at hand, but be selective. The impact that quoting the entire original post has on the size of the archive can not be overstated! - When the poster asks you to respond to him/her personally, DO NOT then go ahead and reply to the List. Be aware that clicking the "reply" button on your mail package does not necessarily send your response to the original poster. You might have to actively address your response with the original poster's email address. - DO NOT use the List to respond to a post unless you have something to add that is relevant and has a broad appeal. "Way to go!", "I agree", and "Congratulations" are all responses that are better sent to the original poster directly, rather than to the List at large. - When responding to others' posts, avoid the feeling that you need to comment on every last point in their posts, unless you can truly contribute something valuable. - Feel free to disagree with other viewpoints, BUT keep your tone polite and respectful. Don't make snide comments, personally attack other listers, or take the moral high ground on an obviously controversial issue. This will only cause a pointless debate that will hurt feelings, waste bandwidth and resolve nothing. ------- [This is an automated posting.] ________________________________ Message 2 _____________________________________ Time: 07:52:33 AM PST US From: "John Anderson" Subject: XDP4000X-List: re: ppi art amps for tweet and mid --> XDP4000X-List message posted by: "John Anderson" List members, have any of you used an PPI art amp in your installs? I am looking for an alternative to the Brax X1400 i am using in my system for tweets and mids w/out a serious loss in SQ, and someone mentioned the PPI Art series as a good alternative. I know that you can get good deals on these units on Ebay, but I would really like some feedback from someone who has heard one. I also have been told that the ADS PQ20 and PS5 would be pretty good and that Harman Kardon, Adcom, Simfoni and Genesis as well as the early Xtants are good choices too. Does anyone have specific model recommendations to look for? my amp rack space is about 9.25" wide and about 20" long. I would need 4 channels of amplification for a dyn 340 system tweet and mid-dome woof. I wanted to use the X1400 in another car b/c it is a bit overkill for the tweets and mid power-wise, but I don't want to lose a ton of SQ and I know that SQ is pretty important when it comes to tweets. I will keep the X2400 for use on the woofer and sub and hopefully the XDP4k would not have any problems w/the change in amp(s). regards, John Watch LIVE baseball games on your computer with MLB.TV, included with MSN Premium! ________________________________ Message 3 _____________________________________ Time: 09:02:25 AM PST US From: Scott Walters Subject: Re: XDP4000X-List: re: ppi art amps for tweet and mid --> XDP4000X-List message posted by: Scott Walters On Fri, 2 Apr 2004, John Anderson wrote: > I also have been told that the ADS PQ20 and PS5 would be pretty good and > > space is about 9.25" wide and about 20" long.

I wanted to use I am currently using the PQ15 and PQ20 for my dyn 340's. 4000 high pass to PQ15 bridged (2x80) to the dyn 360a xover to the tweet/mid, and 4000 low pass to the PQ20 bridged (2x160) to the dyn woofers. I've done the tri amplification to the dyns and there is more 'detail' but coherency is lost in the tweet/mid. Plus I've popped my tweeters adjusting gain (apparently the dyn tweets are sensitive to this without an impedance cap/crossover) I don't like the PQ20 bridged to the woofers. Seems at higher volumes they can 'lose control of the woofer' and I get pops. At one point I ran the lowpass from the 4000 into my JL amp and then highpassed 40-45Hz, and it got rid of the pops, but the line output of the JL can't touch the 4000 and I lost the umph. I've also tried 2x80, but the Dyn woofers need more to sing . . . . The ADS amps are great value SQ, but I don't think they shine when they are bridged. But since you are tri-amping you won't have that problem. The PQ20 might be more overkill though for the tweet/mid, but given the price (I got mine for 225 ebay), i doubt you'll stay up at night . . .
