Product Details

Selenium 8MB4P 8" Woofer / Midbass Speaker

The Selenium 8MB4P 8" Woofer/Midbass Speaker was designed for professional sound reinforcement applications. It features high power handling capacity, smooth and extended midrange response, excellent sensitivity, and admirable durability. The 8MB4P is capable of delivering articulate, extremely high SPL midrange output with a minimum of coloration or distortion.

Engineered for maximum versatility, the 8MB4P delivers great results when installed in compact closed or vented enclosures and horn-loaded designs. General construction details include a sturdy cast aluminum frame, impregnated cloth surround, optimized spider, and a large pole piece vent channel to reduce voice coil heat and increase power handling.

Although it is intended primarily for dedicated midrange coverage, the Selenium 8MB4P will also perform well as the low frequency component in compact 2-way monitor systems that do not require extended bass output.

Selenium 8MB4P 8" Woofer / Midbass Speaker

How would this sound as a midrange speaker?

looking for a high end midrange that will be in a custom 3-way front tower to do mixed duties like music (mixed genre) and home theatre, this system needs to be able to be VERY loud for music and have accurate sound for home theatre.Your help with this is appreciated!!!
Asked by: 12c4u
This would work very well as a midrange speaker in an application like that. It will handle its full rated power as long as it is high-passed around 350 Hz or higher.
