See the ELAC ANDANTE RANGE

The Elac Andante range of speakers

Which previewed at last year’s CES in Las Vegas.  The range is comprised  of three models: the AF-GI floor standers $9,995 per pair , AS-61 stand-mounts |$-1,995 per pair, and an AC-61 center-channel $3,295. The Andante range was conceived as being an entry-level first step into high-end audio, according to Elac designer Andrew Jones, who says that all the drivers used in the Andante series were designed specifically for the series, with Elac leveraging its proprietary concentric
driver technology for the mid range/tweeter.

The Andante AF-61 harks back to Linn's 'Isobarik' speakers, where a driver hidden inside the cabinet modifies the output of another  driver that's conventionally mounted on the front baffle, but Jones refers to the particular implementation in the Andante 61 as ‘an inter-port-coupled  cabinet, where the low-pass filter comes after the driver, not before.'

In the case of the Elac Andante AS-61 stand-mount design, it's the output of a front-firing 203mm bass driver that’s being modified. The internal driver has a diameter of 165mm. Also front-filing
on this model is a 127mm mid-range driver, mounted coaxially in the center of which a 25mm tweeter.
