Challenger M -65 was the first speaker in Dynavoice series and has been a bestseller ever since. Challenger M -65 has been upgraded in several stages and now we're up to version 4. The difference between version 3 and version 4 is the only design, when it comes to the sound, we have not found anything to improve. M -65 EX version 4 have rounded corners and a new design on the front and cloth grille. We think this is by far the best looking version of the M- 65 EX so far and we are sure that Challenger M -65 will remain on the throne, now even more secure than before The Cabinet
The cabinet to M -65 is designed for maximum stability. This is to provide a tight hifi sound without cabinet resonances. All the walls in the cabinet are 18 mm MDF, a plurality of struts are fitted in the box to give even more stabilizing. Treble and midrange are located in a box so that the elements will not interfere with each other. If you do a simpleknock test" on the box you understand what we mean...

Overall, this gives a really solid speaker with a weight of 27 kg. The new EX version has been equipped with piano lacquered front to give the speaker the upscale look it deserves.  

Dynavoice X-Change
At the top of the terminals are three gold-plated connectors. These are used to fine-tune the critical midrange area as desired. Choose between -2 dB / 0 dB / +2 dB / +4 dB. Modification of connectors means that you change the speaker's character. Then you do not have to adjust the bass / treble controls on the amp to get the sound you want.

By placing the bracket in the various X-Change - holes you make changes in the 4 kHz - 20 kHz range. On the picture you can see how the sound is affected when you move the bracket. Without the bracket the level drops by 2 dB, with the bracket mounted the level changes with the number of dB written between the holes.  

Elements
All elements are developed together with the crossover and cabinet to optimize for best sound. The tweeter is a Super Audio tweeter that is capable of playing very loud and clean. The midrange speaker is made of carbon fiber and provides good power and clarity to voices and the basses are made in kevlar, it gives the speed and the pressure that you desire. Together the elements give a very neutral sound and a sensitivity of less than 93 dB! The high sensitivity is a major advantage, especially for smaller amplifiers.

The speaker is equipped with 4 port tubes. The speaker acoustic characteristics can be adjusted whit the bass dampers that are supplied whit the speaker.
