Birch vs. MDF test (spl results inside)

[PSturmer 10+ year member]

two identical box's were made. one out of mdf, and the other birch. the specs on them are 1.25 cubic feet net with .75

'' wood thickness. each had a 12'' type R. both box's were sanded in the interior walls with the same grit sand paper. both speakers were brand new. voltage was held constant on battery.

mdf:

1100 watts: 139.8

2800 watts: 143.7

birch

1100 watts: 139.8

2800 watts: 143.7

both had the same output. this may change when larger box's are used, but when small box's are used one does not have the benefit over the other in terms of spl.

here is the birch box

and here is the equipment. i am still in the process of making the bus bars for the my car so thats why the amps are not in there.

Very nice Test man and good results.

2800 watts on a type R? crazy.

This test confirmed my suspicions, though - thanks. Didn't think there was any SPL benefit between birch and MDF, and I was correct.

Interesting results.

Although I never considered one over the other for SPL reasons.

Thanks for spending the time though.
