French-Fries,
I have not heard the Alexandria's but when you mentioned the $ 135,000 price tag I thought I would have a look at the reviews. I have heard other lower priced Wilson's before and thought they sounded very good, although a bit too much harmonics (resonance) for my taste.
I was shocked to read that Wilson still uses ordinary commercially available driversin these exceptionally priced speaker; drivers that are used by many other speaker manufacturers.
Reasonably priced speakers naturally use third party drivers. This reduces construction costs by outsourcing the most significant components and leaving only cabinet design and driver integration to the speaker manufacturer.
I would demand unique higher quality drivers for that kind of price....not just good "modified" commercially available drivers.
