The flagship model of Magnepan four-band isodynamic speakers. The kit includes two main three-band panels and two separate bass panels.The main panels (MID-bass, middle and high) include two quasi-ribbon radiators and one (on HF) ribbon with a vanishing aluminum ribbon of low mass.
Magnepan 20.7 three-band quasi-tape speakers over the entire frequency spectrum are now at the very top of the company's lineup – the loudspeakers use rod magnets on both sides of the frame and radiators with dacron membranes. A consensus on speaker amplification has already been found – this is VTL Wotan MB-1250 with a power of 1,250 watts per channel, just as much will be optimal for the most severe combination of low resistance and sensitivity.
In terms of physical parameters, the 3.7 model is identical to 3.6. except for the sensitivity, which has become slightly higher. The i index indicates that the speaker radiators have undergone in-depth refinement, the results of which can be heard in a direct comparison of the new and old versions.
The three-band intermediate model is between 3.7 and 1.7. It differs from the latter by a real TrueRibbon ribbon RF emitter with a length of 1041 mm. The bass and midrange parts are traditional quasi-ribbon dacron-based.
The model generates a record-breaking stable localization of the sound stage, which is weakly dependent on the location of the listener. This effect is especially pronounced when the speakers are installed with RF sections facing out, in contrast to the recommendation generally accepted for Magnepan panel speakers (RF sections facing in).
