High value, giant killer speakers?

Fritz.

Very high quality parts, unique crossovers with minimalist parts. I've seen Wilson and Gamut put similar quality parts in, achieve less and charge more.

achieve less

how do they achieve less?

@kenjit ,I believe Fritz is trying to say that despite using the best parts, they don't achieve the greatest potential.-Only a talented designer can make full use of such parts and implement them far beyond what they offer at face value.
-Kind of a 'Pearls before swine', situation.

The Fritz “secret sauce” is his “series” crossover designs that provide a benign load for amps to drive which gets more bang per buck out of the amp.

It works! I’ve heard not particularly efficient Fritz Carerra run off a flea power headphone tube amp rival most anything else heard at same show. Very impressive!

Check his his website for charts that demonstrate.

Perhaps search for a high quality USED speaker for 1/2 price when new.
