Pyramid W64 6-1/2" Pro Plus Midbass Woofer is rated 4.3214 out of 5 by 28.
Rated 5 out of 5 by from Used as Midbass in Kickpanels in my carBuild boxes as per specs .07 cuft out of fiberglass, these speakers perform very well, I'm running 75 watts to each, cross over from 80 Hz up to 1 kHz. after running a RTA and some tuning I'm amazed on the output. for me this is a speaker that performs as good or even better than some high end audio speakers that I own.

Rated 5 out of 5 by from Wow - great valueCouldn't be happier for any price. All speakers sound the same and are very well built. Used them on some vintage speakers of mine and they have given them another 25 years of life.

Rated 5 out of 5 by from Great Jeep Wrangler Center Console ReplacementAs the title says - I used this to replace the blown sub-woofer in my 2003 Wrangler Center Console. The original is a tad larger so new holes needed to be drilled for mounting and only the red and gray wires from the factory harness get used since the original was a DVC sub. It works great!!! I was immediately suprised at how much kick this little mid sub has! By no means is this a competition sub - but for the money it has to be one of the best values out there!! YOU WILL NOT BE DISAPPOINTED!!!!

Pyramid W64 6-1/2" Pro Plus Midbass Woofer

I previously asked about internal volume of 0.07 cu ft it's ok for this driver! what if my internal volume is 0.16 cu ft sealed? is that ok, I'm going to x-over 80Hz to 1kHz  I'm just wondering if the extra air space will compromise sound?

Asked by: DV2015CLA
Putting this in a slightly larger enclosure will not effect the results if you are high passing these at 80 Hz.

This looks interesting...will it work as a door speaker in a 2014 Honda Accord? I have no issues with drilling new hole locations.

Asked by: Doffieboy
Yes it will work, although it will only produce upper bass and midrange frequencies. If you have a separate tweeter this will work fine.

Want to run this driver on a car head unit. 2 towers, 1 driver & a 3 way. Driver separate compartment from 3 way. Box size?Sealed or ported?Spec says .07 other guy says .2? I want decent bass.I can change htz on head unit 60 to 120 mid hi & low & db Level

Asked by: Beanbo
Using measured parameters from the WT3 I would recommend a sealed box of 0.7 to 1 cubic foot sealed. This will provide an F3 of 74 Hz with usable in room response reaching into the 40's.

I need to replace 6 1/2 inch speakers in a small Kustom PA. Each enclosure has 2- 6 1/2's and a tweeter. The 6  1/2s are 4 ohm, 30 watts (rms), 60-8 kHz , 1 inch Kapton. Will these work for my needs? If not, can you make a recommendation? Thx. 

Asked by: Finster
These will work but will be limited with overall sensitivity. I would recommend the PRV below instead.http://www.parts-express.com/prv-audio-6mb200-4-6-1-2-midbass-woofer-4-ohm--294-2703

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

Asked by: DV2015CLA
Yes the recommended volume sealed is 0.07 cubic feet which will work well for those crossover points.
