The 8MR500SEAL PRO offers very smooth midrange response to the upper midrange up to 7,500 Hz. Designed to provide definition and high output on midrange frequencies, perfect for use in any high output 3-way system.

Now you can pair this 8" speaker with any 10" or 12" speaker from our PRO Series, to build the ultimate custom Chuchero® or PRO Audio systems.

  • A sealed back basket simplifies cabinet manufacture, eliminating the need for a separate enclosure for other speakers.
  • Capable of handling 500 Watt RMS this midrange has enough output capability to keep up with the most powerful drivers, suitable for use in 3-way cabinet systems ( Midbass + Seal Basket + High Frequency Driver or Tweeter).
  • Its naturally damped paper cone is coated with a waterproof coating, ensuring high performance even in harsh damp or wet weather conditions.
  • Optimized to deliver detailed reproduction of mid-range frequencies from 300Hz to 7,500Hz. A powerful output peak at 400hz reaches 104dB of sensitivity at 1w/1m.

A light paper cone is mated to a large 2" voice coil for great power handling of 500 watts. A durable spider suspension, woven cloth surround, and closed back
pressed steel basket are combined for durability over many hours of use.

Cabinet builders gravitate towards this driver for use in their systems when looking for a powerful sealed basket midrange, to keep up with high sensitivity low frequency speakers.

Using a closed basket design in a speaker like the 8MR500SEAL PRO offers several advantages. Firstly, it prevents interference from a woofer or midbass in a shared cabinet design, 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.
