I think the talon's are one of the best speakers I've heard. They have outstanding bass response. Their high range and upper mids are 1/2 a notch below the very best (which are in the 20-40k range or have limited bass), but the overall sound is excellent. They fill in the lower registers better than any other speaker of their size and price (the 15k retail one). They are also fairly efficient so they allow you to use a medium sized tube amp (like the tenors). There is nothing quite like having the foundation of a full range system.
I think they just had rocky start with some of their model/manufacturing changes and pricing strategies. Some of the models on the market were kind of 'interim' models. The old style khorus cabinet with the khorus X crossovers for example. There were quite a few of those on the market once the full bore Khorus X was out. I think quite a few dealers were scrambling to get rid of them which in turn hurt the value of the entire brand.
I think they are one of the very best sounding speakers out there. For a full range, they are in the top 4-5 models that I would consider for myself. I hope to see them around for many years to come. Their products deserve it.
