Thunder 4000 Series

The finest amplifiers deserve to be paired with superior quality subwoofers. MTX Audio introduces a clever mix of leading-edge technology designed to play deep, low bass in a variety of enclosures: sealed, vented or bandpass. The redesigned Thunder4000 series features Spider Plateau Venting for cooler voice coil operation and greater reliability during heavy bass passages. Instead of “pushing and pulling” super-heated air over the voice coil like conventional, rear vented subwoofers, Thunder4000s shed the heat out the sides of the spider. The result is cooler operation during all-night “crank-it-up” bass sessions. Thunder4000 subwooferss are available in 4-ohm or 8-ohm impedances. Asymmetrical Linear Drive (ALD) technology, used on all MTX Audio Thunder subs, provides high output with low distortion, thanks to flat progressive spiders and extended pole pieces. These subs are packed with features to help dissipate heat and deliver thunderous bass output. Thunder4000 subs have rugged folded-window steel baskets, 1-1/2" voice coils with Apical voice coil formers, and machined front and back plates. The unique radius venting on the pole piece minimizes turbulence that occurs during large excursions, so when you turn the music WAY up, you won't hear that "heavy breathing" sound (unless it's your own). All of these features add to the Thunder4000's cool factor - literally.
