Acrylic covers for your amps would be nice and would not react with the transformers as compared to metal covers......

Salamat sir... Mixed ng  solid wood, plywood & MDF. front panel plywood used in cargo shipping, maganda lang yung outer layer. Side panels & woofer enclosure made form old furniture. Base from local furniture shop but not good quality so wood grain not clear on varnish.

Same wood used in the crossover box...

Just delivered...

Electro Voice 15" EVM-15L






Magnets bit soiled and no markings to ID the drivers. Cast frame and cone look in very good condition and works perfectly. My source gave me this info, Electro-Voice EVM-15L.

Detailed specs:

http://www.electrovoice.com/downloadfile.php?i=971123


- Any recommendation of type and size of enclosure. Frequency range where it will work best based on specs link above.

Those EVs are great for midbass horns!

Not so much LF, IMO, because of high Fs.

I thought the usable frequency response is 60-6000hz.

Inlowsound, if I'm not mistaken. designed before a midbass horn based on the EVM15l. It's the one pictured below where the JBL tweeter sits.


These midbass horns are actually what I'm using at home but with Altec 803 woofers as drivers. These, in my experience, are best mated with midhorns for coherency and vice-versa.
