Talon khorus vs. Nola Viper iia

sonically which of these speakers is better with solid state? what are the strenghts and weaknesses of each?

should i look elswhere on the used market?
I would do a lot of research on the Khorus. From what I recall, there were several iterations on this speaker and some had pretty significant flaws that were discussed by the original designer in published articles - hence so many iterations. I am not pointing this out to you to disuade looking at these speakers, just perhaps something you should be aware of.

Alon (now known as Nola) made some great speakers for many years. I am not 100% clear on the differences between the Alon speakers and the Nola speakers and whether they follow the same tradition.

It seems surprising to me that of the two speaker brands you seem to have it narrowed down to, they both have interesting and somewhat storied company backgrounds. But that may be why both products can be had at what seem like very good prices.
The Khorus is a mess of a speaker. No bass, a muffled and distant midrange. Serious phase issues. Everything sounds like a blanket was thrown over them. Have to be cranked to max to sound good and by then you are deaf.
Funny thing is that there was a reveiw of the Khorus' when they came out, driven by class D amps. The "professional" reviewer gushed all over them and the amps.

Less than a year later both designers reported that the designs of these reviewed products were flawed and hence the poor performance that consumers were reporting. Seems funny the professional reviewed raved about both flawed products - makes one wonder if the "professional reviewers" have any integrity whatsoever or are just plain old deaf.
The Khorus has some of the best bass i've ever heard, fast and deep. Have you ever owned the speaker, I have. For the price they are selling for now there a steal.
My Rel subwoofers have great bass, but that doesn't make them a good speaker, just good at bass.

What I can suggest is that anybody even considering this speaker is to listen and listen long and do your research. When the designer of the speaker admits all the mistakes with the design and implementation and reports that they are flawed speakers, that to me says a lot.

I have not heard them, and I also never said they didn't sound good, just reported what the designer admitted. There were many changes, apparently often haphazard and untested prior to unleashing the changes on existing and new owners - only requiring even more changes The one thing nice was they were designed by an individual who seemed very humble and open to admitting his mistakes and the major flaws he reported in the speakers. It would be nice to see this more often, and not just when it's time to sell a new and improved model.

The company has a storied past. If one loves the sound, they should buy them (if they keep speakers for many, many years), as is true with all equipment. Just don't complain to anybody when you can't re-sell them or can only get pennies on the dollar you paid for them, after already getting a 75% discount off of list price when you bought them.
