GW-8004 Full Range Coaxial in Sealed (Four Matching Enclosures)

[MalVeauX]

Hi all,

I used the inexpensive GW-8004/8 drivers ($30) in sealed enclosures after discovering they just were not going to work out as open baffle for my intended use (surrounds in my home theater room) due to size requirements and expecting too much of such an inexpensive driver with limited capabilities. So I went sealed. Simple. I did some two tone sealed enclosures in pine & birch to mount the drivers flush in a very low profile box, only 4.5" deep.

Sealed Enclosure, 0.2 ft^3 net internal volume
15" x 10" x 4.5" dimensions external

Finished results:

DSP/EQ will cut the hump around 12khz to tame that down. The 7khz dip is inherent to the driver (in their manufacturer graph):

Very best,

Very nice……AVR sound field management should be able to EQ out some of that 8k suckout if it’s not smooth already at the LP.

And just in case it’s a manufacturing error, I’d take one and swap the polarity of the tweeter if the wires are accessible and re measure.
