SKU agallo-tr3d Category Brand:

The Gallo TR-3D subwoofer is a high-output, dynamic subwoofer which offers top notch performance and amazing bass equalization. It features an array of capabilities and precise bass control, with the rear panel providing continuously variable phase and low-pass frequency, as well as bass EQ from 0 to +3dB and +6dB, which transforms any room into a multiplex or an arena. This is a heavy piece of audio equipment as well, with a hardened steel housing that makes its build quality apparent.

The new Class D amp (with enough precise bass control to satisfy your exact tastes) is coupled with the Ceramic Anodized Aluminum Cone Long Throw 10” Driver and features our panted S2 bass loading technology. But we can throw out numbers and specs all day long – the proof is in the sound. And the TR-3D delivers. It sounds amazing – the bass is rich and deep, but never intrusive (unless, of course, you wish it to be – you “Bass People” know who you are, and you’ll love tweaking your new TR-3D to shake the room.) Bottom line: the TR-3D is a high quality subwoofer which sounds great with both music and movies, regardless of room size.

This speaker won a 2015 Editor’s Choice award at the Absolute Sound
