DECWARE / High Efficiency speaker model NFX

Single Driver Loudspeaker featuring the DFR8 full range driver in an ultra-flex cabinet design.

Crossoverless wide range performance from 50Hz ~ 25kHz.

A true 99 dB 1w/1m efficiency!

Incredibly big and open sounding with no midrange shout.

Uncanny speed makes it comparable to a good electrostatic panel.

Good weight and balance make it more than usable on it's own without a sub.

If you've steered away from single driver speakers because of the typical tipped-up response and in-your-face sound, this is the exception you've been looking for.

The Nibbelin Ultraflex are similar in sound to an open baffle but have bass with good weight and tone. In the midrange the cabinet design acts like a one-way valve (check valve) over a large band of frequencies. Sound inside the cabinet exits instantaneously leaving little to no sound to reflect back to the driver.

High band frequencies are handled by foam spheres placed inside the cabinet in a vertical line to eliminate all parallel surfaces. The actual number of spheres can be adjusted to taste.

The result is simply the most non-congested sounding cabinet you've ever heard next to an open baffle. Very nice balance, non-peaky, non-beamy, great tone and an absolutely huge wall of sound with excellent depth and no holes.

The efficiency is conservatively rated on this speaker making it a great choice with fine low power tube gear. At the same time it does some pretty impressive things with bigger amps.
