The Quick, Cheap and Dirty Speaker Challenge

[jonnoshore]

I have some loft board which could qualify and some 2 way car speakers I've had in the loft for a while..

Is using a jig saw allowed.. or can I only use these loft boards whole ...

If only whole it may have to be an open baffle with loft board sides and FC centres to hold the drive units .. May make nice garden speakers for the summer..

Another entry in foam core - back loaded, rear firing, floor standing horn

This may remind you of another certain speaker, which I have been banned from mentioning by name since it deviates significantly from the speaker which it pays homage to...

I will enter this speaker as it took about 6 hrs and costs under $20.

This my entry. I don't think I spent a nickel on it. And I made most of it in a phone booth with my teeth

Bigun,
Nice! Do you have measurements or sound clips? Would love to hear it...

You have some very talented and straight teeth that do amazing cuts!

Ok, if Cal is entering the Cornu, I want to enter my (0.4x) Karlsonator I built in 4.5 hours, see post 178 on this link for proof. The cost: $10.00 for the driver, $1.00 for the binding posts, $1.50 for the foam and about $1.50 for the instant glue for a total of $14.00. Now I just have to post a sound clip. Mini Karlsonator (0.53X) with Dual TC9FD's

Cornucopya's don't qualify, but the Penthorns do if you don't count the two cuts at the top of the baffle wood to make the point. I won the CSS woofers in a raffle Creative Sound - Product Details, the tweeters were a gift that look to be automotive in nature, there are no binding posts, the insulation came from the attic, the wire I took from a toaster cable, the caps came from someones computer, the coils are old transformers, the baffle wood are cut offs from a Cornu. Total cost is the $1 raffle ticket plus things like half an old tube of caulk, a few pennies of wood glue and some glue sticks, so less than the $20 limit.

EDIT: I guess I cut the holes in the baffles for the drivers with power tools also. Damn, I thought this was going to be a darn good entry. Also, you don't say it has to be FR drivers but this is the FR forums so...

Cal,
I think your Pentahorn entry probably is a leading contender at this point. Although it really is front loaded with some premium "free" drivers. to make your submission complete, another video posting of how it sounds would be awesome. The last one you posted of the big RS 40-1354 Cornu was great. Really enjoyed that.
