Blew a pair of tweeters on my PSB Image -T65

[3db]

I think I know the couple of events that caused the initial damage and they were completely accidental. Pisses me off. I really would like to get stalk tweeters for them.

It sounds like, you will have something to do on your spare time. Have some fun and enjoy the new sound!

This tweeter doesn't seem to be the same unit as the one shown by @3db. Unless it has the same or very close Thiele/Small parameters as his, there's not much possibility of a successful match with the other drivers in each cabinet.

I think those speakers are still current, so they should be able to send you replacements. My guess is that these are Audax titanium tweeters fitted with a waveguide.

I would think PSB will send you replacements. If not see if they will give you the TS parameters of the tweeters. Modifying the crossover to take an Audax Titanium tweeter should not be all that difficult.

By the way, fessup! How did this happen?

The back looks identical, except for adding G in the model number. $35 as far as parts-cannon-diagnostics goes, it is pretty cheap if you ask me.

If you really want to know, I was running emby directly from the AVR and for some reason, it started playing the music at max volume of the AVR. This happened twice and after that, I decided never to run Emby directly from the AVR again. I have to get a Roku in that system so I can use Emby instead of the cumbersome Iomega media player.

I'm in a better mood and somewhat less stressed out after reading an email from customer support. I wrote them early this afternoon (12:30ish) inquiring about replacement tweeters for the PSB Image T65s. I had a response by 3:24pm today. This what they said,

"The original tweeter is no longer available. We have a replacement tweeter for it , part number is PSB IM 11CN/INT, you cost is $60.71/each. Shipping is $10.00."

I asked them if the frequency response and impedance matched the original drivers. I also asked for the frequency response and impedance curves for the replacements just to see how close the replacement parts are.

Thank you for that info. Not really your fault. I had never heard of Emby. I just stream from my HTPC, DAW and the odd App on the smart TV.

I highly doubt the crossovers won't need a mod if the tweeters are not the same. If you can get the data on both tweeters and the crossover circuit, I can help you with a mod. That was a strange event and it is amazing what can happen in the digital age.

I did look at the data on those speakers on Erin's site. One problem is a significant FR issue in the 1000 Hz area that Erin said definitely affects speech. That is not surprising given the location of the problem. The also have a slightly recessed mid/HF range above that and then a rising response at the top end of the tweeter range. The latter is common with very hard metal domes.

The bigger issue is the peak centered around 100 Hz. That I would not like at all. I think this arises from the bass tuning. I am sure they used an extended bass alignment so they could advertise a lower F3 which is in the 40 to 50 Hz range. Then the LF does fall off slower to give a fairly low -10db point in the low 30 Hz range.

So in essence those speakers are in need of revision in my view. I do wish commercial speaker manufacturers would kick out there darned marketers. A lot better decisions could have been made. However I suspect that serious issue in and around 1 KHz is a cone break up issue. So that would not easily be put right without a driver redesign.
