Thank you very much for your response and wonderful history lesson on the CS3. I was 18 when my uncle purchased these and I learned most of what I know about jazz from him, and through the CS3's. Lovely memories.  

As I mentioned, the tweeter cavity is not deep enough for the Morel and I'm hoping for advice on the best method of modifying it. The long screw at the center of the cavity appears to be an important part of the structural integrity, so I imagine removing it and simply opening the cavity completely is not the best course. What would you advise? Also hoping for a couple suggestions on a repair technician for the bass equalizer.

Thanks again 

Curious if anyone here knows the CS3 frequency response without the Bass EQ? I have the original documentation that came with my CS3's but it only shows the response with the Bass EQ.

Hello to everyone on this forum. I have recently taken possession of a pair of CS3's that my late uncle purchased new 3/17/1984, serial numbers 0275 & 0276 and am in need of repair advice from this wonderfully knowledgeable group.

1) I am in the process of replacing the non-functional original Dynaudio  tweeters with Morel MDT 32S. The Morels are deeper by approximately 5mm so I need to remove material at the back of the cavity to accommodate. What is the best tool for the application?

2) The bass equalizer has a noisy (hissing, popping) right channel and I want to have it repaired. Does anyone have a recommendation other than the venerable Rob Gillum?  

Thank You,

Jim

Rob Gillum recommended the Morels. I looked high and low for the Dynaudios and placed an order with High Performance Stereo, but ended up having to get PayPal involved because they took my money and never shipped and would not respond to my inquiries. I advise everyone here to be cautious dealing with them.

I did in fact remove the 5.5" lag bolt and used a (perfect fit) 3" hole saw to remove the back of the cavity. The piece that came out was 1/2" deep. The Morel MDT32S are both in and I have the speakers playing for the first time in 20 years as I type. The fact that you were very likely the one who shaped the baffles on these in the early eighties is pretty special. 

Thank you for the recommendation on the bass equalizer repair. My uncle kept all of the documentation with these speakers and I see that the equalizer was repaired (at no charge!) on 3-8-93 for "popping and static noise on output". The RCA jacks were replaced with the CS3.5 gold type.

Hello Everyone:

I will be pulling my CS3's out of storage after the holidays and trying them in a bi-amp application, which I've never done before. I'll try SS for the low/mid frequency input and Tube for the high frequency input. Am I correct in assuming that the frequency range that the bass equalizer manages is  purely within the low/mid frequency range? Does anyone here know the upper limit of that range?

Thank You,

Jim
