Original Owner of these Planar Ribbon Hybrid Speakers.  Speakers are in Very Good condition.  Speakers Treated with Respect, not abused.  Looking for Local Pickup and audition.  

BG, the world leader in planar ribbon loudspeaker technology, announces two exciting new models from its critically-acclaimed Z-Series. The three-way  oorstanding Z-92 ($1249.50 ea. MSRP) 

Re ecting BG’s latest design technology, both models utilize an advanced three-way design with unique, coaxially-mounted mid and high frequency planar ribbon drivers. This unique approach delivers an ideal solution for accurate sound reproduction with  exibility in placement. The driver’s wide yet controlled dispersion is especially critical for center channel applications to ensure smooth, even coverage for all listeners.

Complementing the three-way design are twin 6.5” black aluminum cone woofers featuring double-gap motors and neodymium magnets. This high performance design delivers high power handling, excellent dynamics and tight, clean bass to rival the amazing clarity of BG’s innovative planar ribbon driver.

> Patented planar-ribbon drivers provide amazing detail and lifelike clarity

> Aluminum woofer cones provide quick response and compatible resolution > Patented double-gap motor technology provides much lower distortion

> Lifetime parts and labor warranty

My speakers are a light maple color, not black ,  Below info is from review


The BG Corp Z-92s are floor standing speakers just under 4 feet tall with the included spikes. The speakers are a 3-way design with anodized black aluminum 6.5″ low mass woofers in their own separate enclosure. BG Corp claims that these woofers have redesigned voice coils and motors to reduce the mass from the previous design and allow the speed of the new woofers to more closely match the speed of the planar-ribbon midrange and planar-ribbon tweeter.

The planar-ribbon drivers are very thin and light weight diaphragms that are printed with an aluminum conductor overlay and these diaphragms are suspended between two very powerful magnetic assemblies in the front and rear of the suspended printed diaphragms. Therefore, the midrange and tweeter drivers are push-pull devices and completely under the control of the amp at all times. The planar-ribbon tweeter is mounted directly in front of the planar-ribbon midrange.

I assume this configuration is to maintain proper phase coherence and as close to a point source as possible.

The two 6.5″ aluminum bass drivers are in their own ported enclosure and cross over to the planar-ribbon midrange at 500Hz and the planar-ribbon midrange crosses at 2.3 kHz to the planar-ribbon tweeter.

The Z-92s are available in a real wood finish of either maple or black ash. They are furnished with rubber feet or metal spikes. I only used the metal spikes on my carpeted media room floor and all listening was done with the spikes in place. They also can be bi-wired by removing the gold-plated jumpers on the back of the speakers.
