Summo 64

Excellent mid-bass drivers to fill in the needed audio that the factory sound could not accomplish. Pay close attention to enclosure design and these are a powerhouse.

Perfect Punch

I already had ported old school 15" Alpine Type Rs in the back running all the filthy lows, but they were missing that quick punch and couldn't reach those bass guitar riffs. Bought two of these and threw them in a sealed .82 cubic ft box and they sound outstanding. I often times find myself turning my large subs to their minimum and cranking these Massives up to their max because of their clean and crisp response to any and all bass. If you want lower bass, you'll definitely need to port them as others have done. However, if you're just looking for a punchy, low cost, and easy to make remedy to fill the gap, I'd highly recommend sealing them!

Made my own sub box and added the SUMM064 6" SUB WOOFER and the bass it great. Sounds like I have 10s. Great buy!

Very good

You have a smaller car, this thing is perfect! One heck of a punch for a small sub. Dont sit on the fence, just buy it.

Little Beast

This lil beast is amazing. I have it in a center console box, built to spec, in a large 4 door sedan. The output absolutely blows me away. It has no problem reproducing good solid lows. Nobody can believe the sound is coming from such a small speaker. The longer I have it the better it sounds. Couldn't be happier with my purchase.

Great sub

Got these for mid bass i have them in a fiberglass enclosure on my truck doors. The enclosures a tad small. But they still sound good. I just put in the budget nvx 12s and these little 6.5s hit harder and louder than the nvx 12s.. (Pulling the 12s, junk)

Awesome Woofers

I have a set of these 6.5 massive Sumo subwoofers and the mini amp combo and holy cow these things pound harder than my 12s absolutely love them I give them 10 out of 10 I would definitely recommend a subwoofers to everyone and don't let the small size full you these Subs produce insane amounts of Bass

Fast service

These subs seem to be quality speakers, I haven't been too hard on them yet, but they sound great as my mids in my door.

Little Hammers!

Awesome performance for the money! I put 3 of these in a 1.6cf enclosure tuned to 37Hz in my 2012 F-150 Super Crew and they flat out pound. The pair of 8's they replaced simply weren't cutting it. They are being driven by an NVX 1000 watt mono amp and will dig into the upper 20's frequency range with the cabin gain. Couldn't be happier with these subs as my space is limited. For $150 (3 subs) they cant be beat. Output is better than the JL Audio stealthbox in my friends 2015 similar truck. Guess who is selling the JL box? :)

Cant go wrong for the price!

I wanted to try out one of these little 6.5" subs and decided to go with this summon based on specs and price. I built a ported enclosure .7 cu ft net tuned to 35hz and it sounds amazing. You wont believe the output coming out of this little guy when put in a proper ported enclosure. I have nothing bad to say about it.

Massive Audio SUMMO64

So I originally bought these to go in my s10 i got 4 of them. After my s10 project was put on the backbone I threw them in my camry. I have twin girls and needed to fit a stroller in my trunk so I made a custom 1.25cb ft box for all 4 of these tuned to 32 hz and I can still fit a stroller in my trunk. I have them on a Rockford Prime 750.1 so these subs are getting over their recommended RMS but they love it. They sound great but you have to give them a chance to break in and it takes a while I've had them 6 month and Im noticing they are getting louder and louder. Didn't sound this good 3 months ago for sure but these things rock. Ive been in Car audio for over 10 yrs and I am an installer and I have had at least 10 different systems and Installed many and these things for their size are impressive. Sound very clean too only downfall to these is because of their smaller size they don't hit some of the low notes with authority like some good 10s or 12s will do but hey everytime I open my trunk and show these things off everyone just smalls and says all that bass from those little things. Get them now

Good bass small space

Nice bass from a small package. Couldn't get an 8 in this tight spot under my seat. This 6.5 was perfect.

Great sub

I would definitely recommend this subject they are small but sound great
