rehab old genesis II's

genesisII · 13th January 2006, 03:11 PM

Hi,
I have a pair of Genesis II with toasted woofers and passive radiators. since I already replaced these for in-house use, I don't really want to dump a bunch of $ into them for rehab, but thought it might be good build project with no woodworking required. anyway, I know of the original parts available from human speakers, but they aren' t cheap, and I was even considering changing the stock set-up anyway. originally it had an 8" woof and 10" pr. the tweets are intact..obviously I don't want to just slap things in there without any modeling or planning.
dimensions (interior) were: Genesis II 25h 13w 9.5d 1.79 volume in ft3
what are your thoughts? how hard is it to design backwards--i.e. starting with box and backing up to drivers vs. other way around. any suggestions about "mid-line" drivers (not cheapo, but less than the $60 per that human has, unless human's are just that good), as well as modeling. thanks

Huh ? how do you toast a passive radiator ?

Judging by the pictures and info at http://www.humanspeakers.com/
the surrounds are foam, is it that the surrounds are gone ?

If this is the case get the kits to repair the surrounds.

actually, the woofers actually got, um, heated, and caught on fire ! (long story, great party, though), with resultant damage to both woofers and pr's, from the plastic-foam melting and dripping. no one was hurt, luckily, except the speakers. they were of the green foam generation

any ideas?

Hi,

the basic driver layout severely limits your options and the
likelyhood of finding a design that would suit I'd rate as nil.

I'd suggest a new front baffle and the Lyra :

or one of the many 2 x 6.5" midbass / 1" tweeter designs.

I don't mind redoing the baffle, since it is an open-ended project, I was just wondering about starting with the dimensions of my box pre-determined, and not being familiar with the software programs, nor with any similar rehabs of this enclosure. I'm a bit surprised no one has really made any comments, either for new design or for going with the human replacements. I mean, if they were endorsed, I could still do that; it just seemed like a hefty investment in drivers that might not better a well thought-out new design.
thanks sreten!
