Hi All,
I’m selling my 7 channel Performance Series, it’s listed on US Audio Mart. My system was posted here on post #1243.
Has anyone ever compared the PT800/PS1400 to the Studio 590 speakers (also a work of Greg Timbers)? People seem to rave about them online, so I'm tempted to add a set to my collection. I'm curious how they compare. I'm very interested in how the low crossover point of 1.5kHz affects vocals and imaging but I wonder if I can live with the high-frequency rolloff shown in the measurements of the review below, though it appears shallow and minimal or maybe I'm misunderstanding something. Take a look at the frequency response graph in this review.

If anyone is looking for parts or complete speakers, here's a deal, (no affliation):

2x PT800 and a PC600.
Edit: already gone.
I think I've damaged one of my PT800's tweeters. It measures 6 dB lower in output vs my other 3 PT800s, so I opened it up to swap it with another to make sure the tweeter is the culprit, and when I did that, I discovered that all my tweeters have the part number 050625 on their backs. Has anyone found out what was going on with the two different part numbers? Is one better than the other? I was about to buy one of the S speakers to harvest the tweeter, but now I'm thinking I'll need a pair or two so that they'll all match, and I'm wondering how they'll sound different.
Anyone have any success buying the tweeters by themselves? What's their list price? I read that someone was able to buy them from a Canadian distributor. How does one go about doing it that way?
The S-Center uses the 335663-001 tweeter right? I looked it up, and this service manual gives a part number 40DT25BC-DT01. Does this mean that I can buy that tweeter and use it in the PT800? Has anyone taken a tweeter out of an S-Center and confirmed that it is the right tweeter?

My recollection is that there are 2 versions, but the only difference is in the way they mount into the waveguide. With a little finesse they should be interchangeable. Maybe someone else will chime in, but I think there's a sort of a spacer that gets added or subtracted. Been quite a while since I had one apart.
Your memory serves you well, RD. I've harvested those Ti tweeters from S Series units and a little finesse is all it takes for a correct mount. I've used both metal and steel small washers to do this, and I've noticed no difference between the two. Early on, I used plastic so as not to add any metal near the magnet, but of course the screws are metal, so...
Out.
Here's something that adds even more confusion. I found an S-Center for sale (the one with the copper-colored cones, not the Series II model), and the seller was kind enough to take a picture of the back of the tweeter, and the model number is 338059-001, and when I searched that up, it came up as a tweeter for their Series II speakers. I've read that people say the Series II tweeter is incompatible or inferior?
The ones I have, one from a PT800, and one from a S38, both say 335663-001, which is all I can tell you. In that picture, only the mounting strap is visible, the actual driver is underneath. You take that out and pop it into the plastic bracket from the PT800. Though I will also point out that the bracket from the S38 looks just like the one from the PT800, neither one looks like the above photo.
I also have a dead tweeter, is there a place to buy them (Canada?) or is it harvest season only?

Does anyone have experience with the ebay plate amp repair service. They claim to have refurbished many PS1400 plate amps.

I would caution against this for a couple reasons. 1st, shipping an amp has its own set of risks. 2nd, its my feeling that a competent repair person would ask for the entire sub, not just the plate amp. The reason for that is for testing purposes. If they have an actual sub in house for amp testing, that's fine.
My advice is to locate a local shop that does electronics repairs. I've had some array subs repaired that way with good success. Still, they do have good feedback so if you're willing to risk the $190 plus shipping, let us know how it goes.
i do. Totally got scammed. Guy was in the Phx area, out of his house when I looked up the shipping address. But I was desperate. He held onto it for months with no feedback. I had to press constantly and he finally started giving BS about expensive components he’d need to fix it, then finally said he couldn’t fix it, total mess. Didn’t end well. I’ll never do that again through ebay. Problem is I couldn’t and still cannot find a shop locally to work on it. Ended up getting new amps from a forum member on both ps1400s
