Like the cork did it quiet the enclosure?

 

[adason]

I do not think so. It may be just for looks.

..It may be just for looks.

Cork looks good!

-the look of bubbling tar for the baffle, not so much.

 

[adason]

Good enough for cheap project

 

[ScottG]

just because it doesn't cost much, doesn't mean it should look cheap!

I mean - I've done cardboard baffles that looked better.


..besides, cork is actually quite expensive (..even if you got it in "inventory", it's one of those "things" where you question if it's worth it.)



This is what I have on (baffle) supply for a *project like you've got here:

https://www.amazon.com/BalanceFrom-Puzzle-Exercise-Interlocking-Tiles/dp/B074J6Y2JL

-works great to cover-up baffle "sins" and can even help a bit with a grill-cloth (panty-hose) and diffraction!

It's also fairly cheap on a square-foot basis.


*really - who has the time or energy to countersink drivers these days?

 

[adason]

Thanks for the tip.
Beauty is in the eye of beholder.
Sound is what matters first, looks second.

 

[adason]

due to popular demand (ScottG whose cardboard boxes look better) here are some "tar" speakers

 

[ScottG]

^oh no.. lordy no. A visual travesty!

..are there any dead dinosaurs in there? If so, can you sink a well and get rich?

 

[adason]

You are just jealous, aren't you

 

[ScottG]

You are just jealous, aren't you

-if there is real money there!

Ugly? Hah! Amateurs!

 

[ScottG]

-makes me think there should be a "sticky" FUGLY thread for this forum!

I had to comment. That brought back the memory of the styrofoam cooler I had in the back of my 1972 AMC Gremlin. A pair of 6 x 9's mounted in the lid with a good bit of duct tape to avoid the dreaded "cooler hum".

Actually, if you cover Styrofoam surface with fiberglass or similar, you will end up with light but strong material.

I hate to admit it but they actually sound not too bad, they're a bipole, another 8" full ranger on the back.

The Eikos FR1 was a type of foam I believe and that received good reviews back in the day.

I resserected my build and put it in a 4" x 4" x 12" PVC fence post. I lined the inside with Sonic Barrier lightweight vinyl damping sheets. Stuffed it with bonded dacron from Meniscus. I originally kept it (prototype) open as adason did, but this new build is now sealed. I'm loving it.

I used a 0.2 mH and 3.3 uF and no resistor. For bass duty it sits on top of a single RS225 BR cabinet. I originally had 2 RS225's in a Z-frame but prefer a single in a BR. Pics and new measurement attached.

Fence Post.. Nice!


-the whole treble range looks elevated though. Perhaps you listen off-axis?

Thanks. Yes, I listen slightly off-axis.

 

[phivates]

The elevated treble is "air" for some, error for others. Our MMV.
