Would you like to know about Dunlavy mods?

I tried to lift  up my sc 4s  and help you out on the screw size ,but they are too heavy for a one man job.   I would get 8 of every screw size thats close and return the rest.. i think mine were about 3 inches long, but is been many years since i moved them.   Good luck and the bases with probably help tighten up the low end.

Hello! 

This is an ancient thread but seemed like, perhaps the best way to contact you short of trying through Star Sound Technologies...

Looking to potentially recap/refresh my Dunlavy SC-IVs and had a question or two.

Thanks
Tom

I replaced all the sand resistors with Mills and capacitors on my SC4,s years ago and your correct they ,made a huge improvement. I did the same with my Dynaudio S25,s , replaced the sand resistor with Mills, caps with Murdoff MPK and VCap CUTF bypassed with VCap TFTF on the tweeters and WOW you will get all you say u well theaudiotweek. The Dynamics's S25,s are just stunning now.

Those of you who are wondering on the bypassing of the CUTF with the TFTF is because the CUTF is smoother more magical then the detailed TFTF, The CUTF our only avail in smaller Values so I used a 0.01 CUTF bypass with a 1.5 TFTF, this will give you the SQ qualities of the CUTF rather then the TFTF.

I hope this make sinse.
