    interesting email from PG about the rsd's

    i sent them this email last night:

    hi. i am running a set of your RSD65CS comp set, but i am running them active with a Pioneer 880PRS HU and some amps with very good results so far. i don't see the FS of the tweeters published anywhere and was wondering if you'd give out that information as that kind of helps when setting a crossover point for the tweeters. i heard that i can take the FS and double it as the crossover point at a 12db slope. i have tried them at 3.15k/24db and at 4k/24db and both seem to sound fine but was just curious if you'd give out the spec on them. thanks, Jason.

    just got this as a reply:

    Jason,

    Try 1200 to 1500 kHz for your active XO.

    _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

    now, when i first read it i was thinking they meant 1200hz or 1500hz but they say 1200 to 1500 Khz. khz not hz

    i emailed them back asking what they meant and if that was a typo.

    12k or 15k seems crazy high, even if they meant 1.2k or 1.5k that seems a bit low.
    is there even much material above 15k for the tweet to play, do they really expect the mid to play up to 12 or 15k?

    i'm lost.

    these guys are quick, just got this back already...

    No sorry the Fs you are asking about is 1200 to 1500.

    You can cross the tweeters around 2500 to 3000 Hz.

    You may want to add a blocking cap to eliminate any turn on/off thump.

    at that low, 1.2 or 1.5, I'd keep the slope steep.

    ^ no, they are saying thats the fs, they are saying the fs is somewhere in that range. he says try around 2500 to 3000. i have been between 3.15k and 4k. i guess now i know i can try even lower to see the results. i'll now have to try my mids at 2k and the tweets at 2.5k. i am shocked they recommended that low. i was guessing they would say 4-5k to be safe.
