6-1/2" Poly Cone Midbass Woofer 4 Ohm
How would 4 of these in 1.24cu tower react with a 4" wide x 4" deep aero port? Should be tuned close to 62hz.
Hi, im looking to replace my speakers in my BMW. The ones in the BMW are 6.5 inch 2 ohm and the amp is max 40w. Would these woofers be a good option for my BMW even though they are 4 ohm and the amp is 2 ohm?
In most cases the amplifier can drive the rated impedance or higher. a 2 ohm amp should be able to drive a 4 ohm load with no issues at all.

I am building a tower speaker with 4 of these and it will be 1.47 cubic feet. What port tuning frequency would be best for these to provide the loudest bass I can get?
A 4" diameter port that is 10" long will tune the enclosure to 45 Hz. This will provide a big peak in the response around 100 Hz, similar to turning up the bass knob, but it will not play very low.

I plan on running these in a .50 cu. ft. ported cabinet tuned to 45Hz no matter the out come. I like all my completed speaker boxes to be very boomy. What is the lowest frequency this sett up will produce? I am hoping to be able to hit 60Hz or lower.
These will have stronger output at 60 Hz if they stay sealed. Porting them in that volume tuned to 45 will result in a huge peak around 80 Hz, rendering frequencies below that to be virtually inaudible.

Thinking of running 4 of these per cab, series-parrallel, in a 2 way design with the Goldwood GT-520 tweeters crossed at 3k. Could you recommend enclosure size for best overall output and extension? Thanks
These will only really work well sealed and the optimal volume is about 3.5 cubic feet. You can get away with 1.25 heavily stuffed which will reach into the 40's in-room.

I have used some 6-1/2 woofers in a custom Dual Reflex Bandpass box in the past. Very impressed with the output. Any help on box specs would help. I would like to use 2 or 4. Thank you.
