Project Description

Challenger M-85 was the first speaker in the new Dynavoice series and it has been a bestseller since its release.

We are now very proud to introduce the EX version. The sound through Challenger M-65 has always been of excellent quality where we have not found anything to improve. In EX version, the energy has been spent to create a speaker that looks as good as it sounds. We are confident that it will remain on the throne, now safer than ever.

The Cabinet

Cabinet to M-65 is created for maximum stability. This is to provide a tight “hifi sound” without box resonances. All walls, including the top and bottom are in 18mm MDF and sits on several internal braces to stabilize even better.

The tweeter and midrange are completely in separate boxes so that the elements do not interfere with each other. Make a simple “knock test” and you’ll understand what we mean.


At the top of the terminal thus you can find the 3 extra gold-plated contacts.

These are used to fine-tune the critical midrange area for your own taste.

You can choose between -2 dB / 0 dB / +2 dB / +4 dB.

The fact that this area is changed, accordingly changes the whole character of the speaker. You can avoid contriving to change the bass / treble controls on the amplifier to the sound you prefer.
