******************************************************************************
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.

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

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 . . .
I am looking to go brax/zapco 4 channel . . .
