OB my way

Marmotus · 31st July 2008, 10:17 PM

What can I say?.....
. around 99 db SPL
. benign 8 ohms load
. not bass compensation needed at all (some settings in the room needed a few minus clicks for bass!! )
. Baffles completed in two days
. One 8x4 ft phenolic coated plywood sheet (used to cast cement) cut in four to make two 4x2 ft baffles (1.5" section)
. 2241H exact replica (except for little higher Qts, he he!) 18" really an Iron fist in a silk glove...
.10MB1P Selenium 10" Mid felt chassis treated (e x e p t i o n a l)
.D220TI (Flat, from 1k to 21K) (e x e p t . . . . . )
.300 - 2K Xover (from other set, not it's own yet)
the little 30w/ch AIWA used to test no lit 2w led and it was seriously loud
Sorry, no more words... Music waits for me....
Cheers

Awesome.

Tell us about D220TI. This is the one used by Physics CS2... Does it sound NICE ?

Hi Gainphile! Thanks for your comment! I'll tell you that is the first driver I find that is truly transparent, seamless integration with the other drivers.... even without any CD EQ!! Here I can't talk any more about Low-mids and highs.... only a huge Caterpillar of music coming... (or an Aston Martin driven by Bond, yes James Bond, if you like!!!)
More pics coming....
Cheers,
Marcelo

How about a closeup of the crossover - it looks like you did a real clean layout on it.

Also, standing in between the speakers is not the optimal listening position!

Hi sdclc126! Here you can see... They are from a good prject I made some years ago, an interesting 3 way "multi" (It could be used as BR or Sealed and many degrees between) it has LPG titanium tweeters (ruler flat, no nasty breakups), Vifa P13MH (astounding mid), and..... a 12" JVC n.o.s. replacement for ZERO 6 of the 80's (YES, JAPAN!!!)
It seams a tube amp near the speakers.... I'll put some led....

more.
Felt treated Mid Chassis innards, Time aligned (being there done that)
Cheers

Some (!...!) Circular cuts re-used and (in theory, hehe) shaped to break standing waves, lol ....

Hi Marmotus,
congratulations!
Being very fond of OB myself, I see you have got it right.
