"Explain how the Dynamat can cause such a great improvement" :-)) ...

Well, let me try, DR!! :-))

After all, not being a Yanqui, I can proudly proclaim I speak the Queen's Engerlish and (as a denizen of a very minor world power) I don't hold the opinion that my way is the only way! :-)) (It's just that I know all you nay-sayers are severely misguided/retarded! :-)) )

IMO, the mulleted midget has the right idea when he says that MDF does not take away the vibrations which the flapping mylar engenders in the pole piece. And if the pole piece - which incorporates the driver frame (not the overall speaker frame!) - is vibrating, it must be passing vibrations back to the mylar and screwing up the "pure" vibration of the mylar (the Doppler effect!). And the mylar is what is producing the sound!

Now, from my own experience (from making up a hardwood frame for my "full-size" Maggies, after reading all the the raves by punters who'd had Mr Gunn transform their mini-me Maggies) I have to agree with him. A "real wood" frame definitely makes Maggie sound much better! :-))

PG's theory that the wood sucks away the vibrations in the pole piece/driver frame appears correct to me. However, from feeling my pole pieces during music with exceptional bass transients - like "Yello" - there is still some vibration happening (after the hardwood frames). And yes, I know - I don't have "Gunned" Maggies ... I have "Andyr'd Maggies"! So PG will undoubtedly say - that's the problem! :-))

But if the pole piece is vibrating - and IMO this is a bad thing - then sticking Dynamat strips down the length of the pole piece between the pin-holes (which DR has done) can only be a good thing. And it will still be a good thing with an MDF frame - except the maximum benefit won't be achieved with an MDF frame. :-((

But, yes, it's possible that there's an optimum damping ... and not every strip on the pole piece should be Dynaf'ingmatted!! :-)) That needs experimentation, DR! :-))

But, no, I don't think Dynamat will do much good on the actual hardwood frame! :-))

Regards,

Andy
