The 6MR250SEAL offers very smooth midrange response to the upper midrange up to 6 kHz. It is a perfect option as a seal basket speaker replacement in three-way cabinets.

  • Seal back basket simplifies cabinet manufacture, eliminating the need for a separate enclosure for other speakers.
  • Very compact model with only 2.20″ of mounting depth, suitable for use in 3-way cabinet systems ( Midbass + Seal Basket + High Frequency Driver or Tweeter).
  • Optimized to deliver detailed reproduction of mid-range frequencies from 400Hz to 6,000Hz.

A light paper cone is mated to a 1.5″ voice coil for great sensitivity and a 250 watts power handling. A durable spider suspension, woven cloth surround, and stamped steel frame are combined for durability over many hours of use.

Cabinet builders gravitate towards this driver for use in their systems when looking for a lightweight seal basket midrange.

Using a closed basket design in a speaker like the 6MR250SEAL offers several advantages. Firstly, it prevents interference from a woofer or midbass in a small Hi-Fi cabinet, resulting in a cleaner and more accurate midrange response.

Additionally, the closed basket design contributes to a smooth punch of midbass and midrange, enhancing the overall audio performance of the speaker.

Technical Details


*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range.

**Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to provide a clean signal without clipping or saturation.

***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
