Lowther speakers for Fisher X-202-B?

I second Eldartford's recommendation. Other than Fostex, Supravox also offers spkrs without a whizzer.
But you'll need a (super)tweet to reach +20kHz (unless of course you opt for the expensive 215/2000).
If you must go the Lowther way, see if you can afford the EX series. The response is somewhat tamed.

My advice... listen for yourself in your own room. From there you can decide which way to go.Response graphs won't and can't replace a good pair of ears. Everyone has an opinion but the only one that matters is your own!

Good Luck!

For those who have not heard the latest Lowther changes to the whizzer cone, it is a significant improvement over the old whizzer that had no stiffening gusset on the unsupported edge. The new whizzer has a completely different edge shape now, and is not subject to the "tizziness" that was related to the old whizzer shape. It has also significantly reduced the characteristic "shout" in a narrow band of frequencies in the upper midrange, so that the new Lowther versions are a dramatic improvement over the older series. Not perfect, mind you, but much improved. There is also a change in the suspension roll, which also improves the sound over the older series.

While I agree that the whizzer cone does impart some anomalies to the sound in the upper mids(now primarily a small response hump), due to the mechanical characteristics of the interaction of whizzer and main cones, it is still providing a pretty good sound up into the high frequencies(22kHz on axis), without resorting to a crossover and supertweeter.

Whether any particular listener likes the sound of the Lowthers is up to their personal tastes. I will say that virtually all of the available Lowther cabinet designs have serious flaws regarding the baffle-step compensation, and they either use an electronic baffle-step compensation network(which kills off 5db of efficiency in the system, and introduces filter problems), or they have a 5db dropoff in response below the baffle-step frequency of the cabinet being utilized. Either way, the performance that is expected from the driver is compromised, either by losing the direct-drive and high-efficiency benefits if you use a compensation filter, or by losing midbass and bass response if you don't(and use typical narrow cabinets).

Many of the typical Lowther problems that get attributed to the drivers, are really problems in the cabinet designs which were not properly addressed. IMHO.

Short comings and all---about as good in mid-magic as it gets.---Lowthers sound better being driven a receiver than any speaker I know of(also being driven by a receiver).---On the cheap; most will be impressed.--- Yup, my Lowthers are driven by a receiver--- got their center as well.---On voices and most instruments--- will put to shame many big buck cones---But I guess that is subjective and you gotta hear for yourself.

Not to be a contrarian, but I have heard several Lowthers, and was quite smitten with the sound. It is much better than I expected; "sounds" more full range than it measures. The sense of being alive was almost shocking. These speakers had so much presence that I was blown away. Perhaps more like live music than anything else I have come across.

On the other hand, it is definitely a love it or hate it sound. Put it this way, if you like Coincidents, you'll love these. They make my Coincidents sound like they have horse blankets on. Conversely, if you are a Vandersteen guy, like my good friend Scott (Sdcampbell), I would definitely look elsewhere. What I consider live, others will find horrifically upfront and bright. It's all about your tastes, like most things...
