open baffle revelator

[then_dude]

hello,

i have read a lot on this forum and it is very interesting.

i have seen beautifl designs.
i'm intrested in an open baffle construction for the midrage;
ATC is a brand which does it well, but it's very expensive.
scan speak does it also good in this construction; the 8535, of 8542, 8460; but at this moment i can get rather cheap the 8530 revelater, would this be a good dirver for the open baffle, i can get it a 100 euro ( i live in europe)

as a tweeter i would go for the 9700; (9900 is more, but is it also better )

as a woofer i would go for a paper scan speak; or has anybody something betters to offer (that doesnt cost a fortune?)

thanx guys

My suggestion would be to keep it simple and use the Ciare 'full-range' driver (49 euros) and then later add some dipole subs if you need the extra bass.

Will your proposed woofer be on the baffle or in a box?

[then_dude]

the woofer would be in a closed box

here i found inspiration

I can't comment on the choice of drivers but it is a sensible enough design although I would rather do it with active crossovers.

I saw a similar design with active crossovers and the bass box had two drivers firing front and rear with a little EQ.

My rule is unless you have enough experience with designing a ctossover, it is always best to use the same drivers of a tried and tested design (unless you want to do a lot of experimenting).

that's completely true,


but you suggest to buy a full range, and put it in an open baffle ?
indeed, it's not that silly. I never thought of that, i always thought of a single driver in an TQWT;

i'm gonna look a little bit around, thanx alot allready

Pretty good price. Where can you get that? Diyparadiso?

hello, now its not www.diyparadiso.com
but this is one of the cheapest stores in europe, and it is in belgium, yeehaa.

you can get it on ebay; in America its now for 170 euro for two of it, i suppose, that it wil cost about 30-40 euro to get it here;(looking at the german post-prices)

Thanx nuuk, i'm going to read it very good

[capslock]

Could you post or email me their address (web or real)? As a colleage of mine is from Belgium and goes home regularly, it would be easy to mail-order stuff there.

Thanks,

Eric

For midrange you might consider the new Excel driver from Seas, check this: http://www.seas.no/excel_line/excel/E0037.pdf

Also check at the german magazine Klang & Ton, I believe. They've tested a new open baffle design, built by I.T. electronic, if I don't remember wrong.
