I'll have to disagree with Rick though. These are pretty tough to top even in DIY.

The low 1,000Hz to 1,200Hz crossover point of the planar magnetics is a huge advantage of ribbon based designs that must be crossed much higher. They are a lot tougher too. The true ribbons can be very fragile. Just blow on one and see what happens. The planar's are a new W version Neo 3 not available anywhere else at this time.

The Speed and detail level of the four inch woofers are hard to match with any other woofer and nearly impossible with any larger ones. They are a proprietary woofer that was built to my specs.

Low end extension is given up to gain the advantages of the smaller woofers. My personal pair of 20/21's will only -3db down in the mid to low 30's in my room. The 12/12's -3db in the upper 30's to low 40's. The 6/6, mid to upper 40's. So a sub is needed to cover the bottom end. But these were the design goals dictated by the owner of the company. He intends to sell his large subs with the speakers.

There are some deals that can be made on a few select pairs right now that can put the price down into a range where it would be nearly impossible to match even in the DIY market. If serious contact me.

If there is anything else you want to know, just ask.
