Trenner & Freidl ISIS Super sale! Excellent speaker, excellent condition.

In excellent condition, original boxes, no marks, 2 owners. MSRP $40,000.

This has sweet midrange, clear highs, and deep, strong bass. It will provide a big soundstage. An amazing speaker. Read the reviews.

Amazing speakers at a fraction of the price.

This was a trade in. Both owners were smoke free, dedicated audio rooms. Both owners moved up more expensive speakers.

Worldwide shipping $1,000
US Shipping $500.

Some of the reviews

High praise here.

To be honest, let me say that in many respects the Isis were the best speakers I’d ever had at home. For example, I’d never heard such a good soundstage. The speakers offer outstanding holography, showing a fully credible soundstage.
