Goldwood GW-18090 18" Select Series PA Woofer
Goldwood GW-18090 18" Select Series PA Woofer is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Higher Ground SoundI purchased two of these subwoofers and was very pleased with the sound and performance. These subs go down to 20HZ and their clarity and punch are great. I put them in a 6.6 cu ft. enclosure and WOW, heart pounding sound.

Goldwood GW-18090 18" Select Series PA Woofer

Would these work well in a dual 18" PA Subwoofer, and should I port? My plans will be a 20.8 cubic foot box (48" x 30" x 31.5" with 3/4 birch plywood. I have already subtracted internal volume for the driver and internal bracing) 

Asked by: Taylor_B
I would recommend a slot port that is 28-1/2"H x 4"W x 5"D for a tuning frequency of 35 Hz.
