SUMMO64XL

The SUMMO64XL shares vital performance parts from the bigger models in the SUMMOXL line, such as the Kevlar Fiber enhanced non-pressed paper cone and OFC direct leads. In addition, a 4-layer, high temperature voice coil, fiberglass woven dust cap, a high roll surround, and triple black poly cotton spiders with a mirror image layout. All of the DNA from the SUMMOXL line, mixed with the innovative motor design, adds up to a very strong approach to a compact subwoofer that can keep up with the big boys.

Massive Audio SUMMO64XL is a high-performance car subwoofer that delivers powerful and punchy bass. With its dual 4-ohm voice coils, the SUMMO64XL allows for flexible wiring options and compatibility with a wide range of amplifier setups. With its oversized 110 oz. ferrite magnet and high-temperature aluminum voice coil ensure reliable performance, even under demanding conditions./p>

Serious sound in small package

I ordered one of these just to test them out. I built a ported enclosure to the manufacturer specs. This little guy blew away everyone who heard it and swore it was a larger subwoofer. At one point I decided to put my 1200 RMS amplifier to it, do not recommend, it withstood two songs with only a small hint of clipping. after I let it cool down I continued to use it regularly with no issues. Wonderful little subwoofer.

Great in-home subs I'm using

These are great, I'm using them in my lounge room, they add terrific balance with my 6.5.

Massive 6 1/2 thumpers !

I am familiar with car audio, 40 years or so. I have not tried these speakers yet, but I will. I will get 2 more for a build. Decent four channel amp to push them. I will push these buggers and see what they can take.
Sonic electronics is my go-to place. I have and will continue to buy from them.
