Naim Ovator S-600 Loudspeakers
All prices in US dollars.
Although it might look like a conventional three-driver
floorstanding loudspeaker, the technology that lurks within Naims new three-way
Ovator S-600 is anything but.
The trick part of the Ovator is Naims new Balanced
Mode Radiator (BMR) driver. This proprietary device reproduces the midrange and high
frequencies. As Naim describes it, the BMRs operating principle is that of "a
practical implementation of the theoretically wide bandwidth and linear acoustic output of
an unconstrained vibrating diaphragm." Not only is the driver unique, but so is the
way it is mounted to the cabinet.
This vibrating diaphragm, essentially the "cone"
of the driver, is loaded into an aluminum cylinder that terminates on the rear of the
enclosure with a back plate. The entire cylinder is suspended in the tube with leaf
springs, just as the driver itself is on the front of the enclosure. Naim says that this
system decouples the BMR driver and its enclosure from the rest of the cabinet above 4kHz.
The Naim rep pushed on the back plate to show how this sub-enclosure moves freely from the
rest of the enclosure.
There's also another leaf-spring decoupling system on the
bottom plinth that decouples the main cabinet above 12Hz. There are other features, too
many to get into here, but the brochure for the Ovator S-600 does a good job of
illustrating everything that goes on with this speaker, both outside and inside.
Naim rates the Ovator's sensitivity at 88dB, impedance as 4
ohms, and in-room frequency response from 28Hz to 35kHz. The innovative Ovator S-600 is
priced at $10,450 per pair and certainly deserves further investigation.
