Hybrid Speaker M 420 F

The M 420 F column speaker is much more than a conventional column speaker. The special hybrid construction of this speaker allows it to simultaneously function as a passive stereo speaker and an active subwoofer.

Two 130 mm carbon fibre woofers and a 25 mm neodymium tweeter have been implemented in each speaker using the tried-and-tested D’Appollito configuration. Flanked by a 250 mm side-firing subwoofer, the M 420 F has a full-bodied response with incredible bass – and all in an ultra thin design!

The remarkable bass performance of this speaker is made possible by a separate 175 W amplifier which is solely responsible for the subwoofer channel. The tweeter/mid-range driver is located above, and is passively decoupled to handle frequencies from 90 Hz upwards. This driver can easily be seen from the front and is acoustically isolated within the column.

The universal design of the integrated active subwoofer allows it to be connected to the ‘Sub Out’ of your AV receiver or the speaker terminals of your stereo amplifier. In any case, this relieves your amplifier/receiver from bass duties and frees it up to concentrate more on the other frequency ranges.

With a pair of M 420 F speakers, you will dramatically improve the quality of the bass response in your stereo system. When used in a surround sound system, these two column speakers essentially add two subwoofers to your system.

A three-stage volume selector switch allows you to select how much bass is split between the subwoofer and tweeter/mid-range drivers and thus match the system to your listening environment.

This active/passive design delivers bass all the way down to 35 Hz and can generate sound pressure levels as high as 103 dB/m!
