To MOD Or Not To MOD ?????

Some auto sound deadening mastic between the steel plates and enclosures wouldn’t go amiss.

That would completely negate what we are trying to do.

Why?

Are you mass loading the enclosures only?

It is all in back posts.

Simply there is couple and decouple - absorb or transmit. Why mix them, illogical. The Doc mods are about coupling energy, no mechanical capacitors. You are advocating introducing them, so completely against Doc mod principles.

I see. Fair enough. I hadn't read all the info. I'll try your theories out one of these days on some speakers I can afford to scrap if necessary.
The internal bracing could still be an option but I can see the absorbing sheet contradicts the idea.

Hi Ash,
How is it going with the Genexxa monitors? I'm curious.

I am considering a cheap pair of Audiolab Minax-CD speakers for a mod experiment. They are little boxes made by a Dutch company and have a thick glass plate as the top cover of the cabinet. Still pondering.

Glass plate above a certain thickness which I would say is min 15 to 20 mm is an extremely good (but very heavy) material for speaker cabinets. Similar to acrylic but harder with a higher (and less internally damped) resonant frequency. I thought at one stage before I went to acrylic to try glass but the problems involved were too great.

Hi Fretless, Ive got the kit, I just need to make time to build them. I have recieved my LS6, SSP and P50sa now so been playing with that the last couple of days. Get modding again, I cant wait to build them. Ile keep you updated.
