Pyramid W64 6-1/2" Pro Plus Midbass Woofer
Sound quality for car door speaker?
4 ohm, Vas 0.2 cu ft, Qts 0.75, depth 2.75", 96 dB @1W 1m, all indicate good fit for my car door speaker. One review, "above 300 Hz sounds like a cheap alarm clock" is stopping me from buying these. I need 2 way woofer, XO @ about 3200 Hz. I need second opinion. No amp. 15W head unit. Thanks.
I put them in my brothers truck and they sound great off the head unit. I XO at 3500 Hz. with a Goldwood GT-1016 2" x 5" Wide Dispersion Piezo Horn Tweeter. If that helps. I like that they dropped the price form about $15 to $10 :)

Is the vas really only .o2 cu ft? I modeled it and its showing only 74db with that...
i am pretty sure that there was a mistake or typo represented in that drivers parameters, because 0.02cu ft is almost as little as the woofer itself. i think the decimal place is off by one. try modeling it with a 0.2 cu ft air space and see if that is more appropriate. thank you for taking time on this inquiry and i hope this helped.

How big of a box (ported/sealed, which ever would be better) should I build if I want two of them in one box?
I would recommend sealed for this driver, two would be best in 0.4 cubic feet.

Need Vented Port Dimensions
What are the recommended port dimensions (diameter and length) for a round port to achieve F3 of 40Hz? - Thanks
With a volume of .43 cubic feet and a 1.5" diameter, 4" long port you get an F3 of 39.8 Hz although the response does not look good. This driver is much better suited in a sealed enclosure and with its limited Xmax it won't do much below about 80 Hz.

Reading above the recommendations for a sealed box volume is: 0.07 ft.³ Is this correct? or what is the recommended volume for a sealed box? I would like to use them as a Mid-Bass, x-over from 80Hz up to 800Hz. Thank you. Derick
Yes the recommended volume sealed is 0.07 cubic feet which will work well for those crossover points.
