    Here's what a pair of destroyed 906Tis looks like. One just has a cracked and broken frame, while the other is completely destroyed.

    The Performance Series set up in the "Two Jims Theatre" uses a PC600, six PT800s, two PS 1400s (not stacked but used as subs) and two HTPS400s. Of course, the four subs are positioned and calibrated using the Harman International white paper on multisubs, with one sub at the midpoint of each wall. All the satellites are powered by a JBL Performance AVA7, the rebranded seven channel Lexicon amp. The pre/pro is the Fosgate Audionics FAP T1+, hence the Two Jims moniker.*

    The Performance Series stereo set up is now in the music room, with two cherry PT800s mated to Fosgate Audionics FA400 THX subs with JBL LE14H-1 drivers in them. They share the room with L100s, XPL200s, L7s, and an SVA five channel set up (SVA2100, SVA1800, SVA Center).

    And with all that, there's still three PT800s in boxes in the garage. What a sickness!

    It's good to see you recognizing it as such. That said, I have realized my own condition for decades, and with the exception of a few brief moments of sanity, there doesn't seem to be any relief from it. I've even tried listening to Klipsch speakers to break the spell.

    Hi Doug

    sorry to see your loss..WOW..hope you get you money back.

    Oh no, it's not a sickness.. a sickness is an organic malfunction within a living organism

    sadly this is far worst....it's a mental ILLNESS

    There have been many studies of this particular ILLNESS at the Menninger Foundation, but so far nothing conculsive as to it's origin, or remedy has been identified

    It was first thought that maybe the problem was in the Cerebral Cortex, particualrly in the frontal lobe, but all test have failed to pin point anything difinitive. In fact all tests have had an amazing margin of error of 99.9999%, leaving all researchers baffled..

    So far the best they can advise is to just to live with it like John Forbes Nash did with his illness( A Beautifull Mind)

    of course all is not loss. It seems that "group therapy" can help. While not a cure, it does appear that groups such as LHF can help to releive SOME of the underlieing anxiety. Apparently it helps just knowing that there are others who also suffer with this illness.

    all the best Doug....

    4313B's query is both literal and figurative. Literally, when you think about stacking them, are you putting them top-to-top, bottom-to-bottom, or top-to-bottom?

    Figuratively, I think your answer is that you have (or can get) four PT800s but you only have one amp so you want to use all four up front as some kind of array.

    So, you need to answer these questions:
    How will you be stacking them?
    Are you going to try to connect them in series or parallel with two speakers running off each channel in your amp?
    Will you be using a subwoofer or running them full range?

    Off the top of my head, from the bottom of my heart, based on my experience, my gut reaction, after due consideration, is that this is a bad idea unless you have a really clear picture of what you want to do and how to do it. Even in the best of circumstances, the EOS Waveguides will make this much more problematic than flipping over an old L100 and stacking it on another L100.

    they will stacked tweeter to tweeter on top of ps 1400
    run in parallel ( i believe the ps 800 are 8 ohms) with a krell 400 intergrated amp

    Well, the proof is always in the doing. Either you'll like the result, dislike the result, or feel it doesn't make much difference.

    I'd still be concerned about the EOS Waveguides' dispersion patterns competing/conflicting/canceling out each other at various frequencies, but careful listening will reveal whether that happens or not. Also, the PS1400s may not be enough if the combined output of the four PT800s is not controlled and balanced with them.

    Source of Performance Series tweeters

    I picked up a pair of S26 speakers for $60 to harvest the tweeters based on published info that they are direct replacements for the tweeters in the Performance Series. Lo and behold, they are a perfect match, down to the part number.

    Inasmuch as the replacement tweeters list for $52 each and are also described as NLA, this is an inexpensive source of this important part.
