The new and improved version of the 6MR300SEAL offers very smooth Mid Range response to an upper Mid Range of 7 kHz and is a perfect option for driver replacements in three way cabinets. The design results in outstanding durability and a smooth punch of Mid Bass and Mid Range for small Hi-Fi enclosures in home or pro audio.

The 6MR300SEAL v2 has a sealed basket design, permitting it to reside in the same space as larger woofers without causing distortion to the Mid Bass driver. The large magnet assembly is attached to the sturdy reinforced steel enclosed frame completes the 6MR300SEAL v2 to ensure a solid support structure, for long lasting play in most any environment.
