## Description

Massive Audio 6" 400 Watt Subwoofer Dual 4 Ohm Shallow Mount SUMMO64S

## Features

- 🏅 6 INCH SUBWOOFER THAT SOUNDS LIKE A 12 INCH | Double Stacked High Energy Strontium Ferrite Magnets, Customized Vented Cast Baskets and Bolt-To-Box Machined Hex Screw on Magnet Backplate for Maximized Bass via Reduced Box Flexing are a few features that make the SUMMO64S a highly popular and unique subwoofer.
- 🔊 NEW SUBWOOFER DESIGN | Most subwoofers vent via a pole piece on the back of the magnet. The SUMMO64S has a new design that vents from the basket and allows a closed back design allowing you to bolt the back of the magnet to the back of the box to reduce box flexing. This means the extra energy can be used for higher SPL and more bass.
- 💪 AMAZING DEEP BASS FOR ITS SIZE | "Sounds Good" is an understatement. The sound that comes out of this 6 Inch Subwoofer will simply turn heads. This 6 Inch Subwoofer has a power handling of 200 Watts RMS to 400 Watts MAX, 1.5 Inch 4 Layer Voice Coil and 100% Copper Direct Input Wires for Connection.
- ✅ SLIM SHALLOW MOUNT OR FREE AIR | Looking for a free air or a shallow mount subwoofer? With a low profile depth of only 3.6 inches and a sealed back magnet this subwoofer only requires a 0.57 ft3 sealed box. For a bigger sound the optimum ported box designs are only 0.9 ft3
- 💯 MASSIVE AUDIO QUALITY GUARANTEED | Since 1999, Massive Audio has been an industry leader in high performance audio products. Massive Audio laid its roots in high quality audio reproduction through in-house engineering and a dedication to customers.

En la foto viene una bocina de una sola bobina y te van a mandar uno de dos. Le doy cuatro estrellas de cualquier manera por que el sonido es muy bueno es limpio. Lo uso en un hometheater en un cuarto mediano y cumple su función bien
