DIY NS-10 Speakers. DIY NS-10 Speakers It's probably more a sign of being a contrarian than anything, but just when the Yamaha NS-10 was hitting its peak of popularity I was busy messing around with Dynaudio raw drivers.

DIY NS-10 Speakers

Back then they were freely available to the DIY market and I eventually settled on the 17W75XL mid/bass and D-28 AF tweeter in a configuration very similar to that which would later be used in the BM6 passive near-field. For better or worse, that was my "monitor" setup for the next decade or so and like anything I eventually got used to the sound and could make fairly good judgements by them.

Neolev magnetic levitation dampers are our latest development. Placed under near-field monitors, home stereo speakers, turntables etc., they eliminate acoustic feedback and mechanical distortion to bring out the full potential of your gear. Cancellation of contact induced resonance is very effective as forces perpendicular to the device are stopped from being transferred. Based on two repelling Neodium magnets one single NeoLev lifts up to 8kg. NeoLev's are adjustable to ensure perfect levelling.

Sonic improvements from NeoLev damping feet NeoLevs eliminate direct coupling and lower related distortion, we like them under near field monitors or Hi-Fi speakers but the effect is clearly audible with any device they are put under.
