My latest dumb idea

herm · 26th October 2006, 02:53 AM

I've been listening to my Fostex F200A full range speakers
for a week or two now. For Music, the bass is fine. For home
theater, it is not enough (of course).

So here is dumb idea #9,724 :

Sealed F200A (f3 of about 70 hz), with a Dayton Reference
12 incher (RSS315HF) for the bottom two octaves. Active
crossover.

Box based on Troels G.s "Poor Mans Strad"

Heres a picture. Any comments? Insults and sneers are OK too,
as I havent thought it through yet. This is really just a combination
of 1) Not enough to do at work, and 2) Trying desperately to find
a reason to buy two of those delicious looking subs!

P.S. Those are ports on the bottom.

I have that same driver in PartsExpress 3 cu ft sealed boxes.

With Qts: .44 I'm thinking sealed sub box is the way to go.

No input Herm (I have lots of dumb ideas too), but just wanted to say I'm happy to see a fellow San Diegan on the forum!

Nice cab concept. Go for it. Sealed subs, biamp/active xo.

Qts = .44 ?!?!?!

Boy, you guys are right. Sealed makes sense.

Daveis, do you boost at low freq or is room gain enough? The
3 foot box you use models to a beautiful .6 Qtc using Unibox.
Or possibly linkwitz transform?

Here's a link to my box inspiration:

Poor Man's Strad looks high in WAF, just dont introduce it as P.M.S

I am using F200A with 45L sealed enclosures + Sealed Bass modules, Active XO at 80Hz.

In my case, I found it important to have steep High Pass XO for the F200A, since I like to play at high volume

The design reminds me a bit of the Ayon Dragon.
