Oh well. Se la vie. Worked for me very well with a Philips AD W12100 full range in a 120 litre double bass reflex w Fostex bullet tweeters & Silver Fute 5 1/4inch tl hybrid 14 litre w XT25 tweeters. But your negative experience with it is noted for future reference.

Well, c'est la vie ;-)
I made some further experiment today, removing the wool from behind the driver and put a mix of wool/dacron between driver and slot....what an improvement over dacron.
Bass are now powerful...only downside the music seems to flow slower.

Mmm interesting. The stuff Ive always used was the 50/50. I made the assumtion (my bad & always dangerous) that pure wool would be better. Perhaps it is pound for pound more effective and damps higher frequency better than the others therefore less is more effective. That makes sense. The Philips 12 in FR I used it in reqired a notch filter that was reduced in value after adding damping. The XO for the TL was just north of 2.5K very nice life like tone from that one that also features a wool damped cone material (Silver flute 5.25 in) a surprisingly good driver for very little money.
I gots to know why is it so? Works fantastic just behind the drivers in my Peerless 12 in 125 litre bass bins the rest of the fill is polyester & acoustic insulation batts.

If you don't mind wearing some gloves while handling it, acoustic fiberglass (or the type used in HVAC ducts) is extremely effective.

hi Dave,

what i meant is , after lining the speaker walls with damping material, should I still stuff the enclosure with Recron kind of poly filler? the reason i asked is because- my HiVi Swans 1080 monitor speakers have this kind of material stuffed in each of the speaker cabinets.

If it is a bass reflex usually not. In the case of the Mar-Ken no additional damping besides the lining is required.

Thanks, must try.

I nerver thought that damping can be so complex, I use this set-up mostly for night session, very low listening level.
I feel the need to adjust damping to level volume, meaning more volume, more damping.
For night session, less damping...I'm driving crazy or....

Mr Clean Magic Erasers. Same material as BASF professional sound abatement foam liners. Works very well to line area adjacent to driver back side to reduce coloration. Glue with hot melt.
