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 would like to replace the 6.5 mb quart midbass drivers that came in their 3 way set up that are in my doors. would these work, or would you recomend to go with a larger driver like an 8"  75watts rms from an xtant amp

Asked by: TEAMRAD

The specs show an Optimum cabinet size of 0.07 ft3 for Sealed as well as for Vented. I believe both are too small.  1) Can you recommend a size for Sealed 2) And also for Vented w/port dimensions?

Asked by: GusCusi2
Using parameters I measured on the WT3 the volumes are quite a bit different. I would recommend 0.7 sealed for an F3 of 75 Hz. Vented is over 2.2 cubic feet and not recommended for this driver.

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.

Will this Pyramid W64 6 1/2" Pro Plus speeaker be a suitable replacement for the midrange in my 3-way AR 610 speakers? The crossover frequencies are 700 Hz and 5000 Hz.

Asked by: curious62
Yes this will work for that application.

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.
