Lowther's and the B200 have the same characteristic. Toward the upper end it's outside our most sensitive region of hearing, so it'll likely just make it seem detailed. For myself, I'd stick with the standard version though.
I'ld agree for the most part (that's why the delayed roll-off is only a slight benefit) but the low treble region where it already goes wrong (4-6khz) can cause more nuissances. Lowthers aren't really famous for their non-shout character either; strange I haven't read anything bad about the B200 although the rise in response is very obvious. Maybe FR graphs aren't that determining after all........

but when that messes up the higher mids than I don't see the point.... (there was the same discussion on forum.zelfbouwaudio.nl, same result....)
True enough. Still, some people like a slightly hot upper midrange as it subjectively gives more forward vocals. Not something I like, but to each their own!
Hi,
did someone really try listening off axis to the spectrum-L8?
A 8" FR driver, with no whizzer, has a very directional response from the mids on. If the driver is set up to have a linear response on axis, you will have less mid/high frequencies energy in the room, than bass and low mids (which are radiated into 1/2 or even fullspace). So in theory, as the reflected waves do also have an influence on the overall timbre of the sound in room, a rising MF/HF response can compensate for that while you still have a linear reponse when listening with the speakers not tied in (off axis 20 - 30°).

Doesn't make sense to me. If the aim is to have a radiation pattern of which the sum is as flat as possible in all possible directions it would seem beneficial, say at a supermarket. If you're sitting in your couch on-axis with the speakers as most critical listeners probably do I can't imagine a reason why you should sacrifice on-axis FR. I think you'll need lots of imagination to turn the better off-axis behaviour into a benefit that outweighs the loss in on-axis response, in the listening environment I suspect most people here inhabit. I never heard people champion the Lowther high-mid shout as a benefit that makes for better off-axis response, some do tilt their speakers to make it more bearable ---- but that's only a remedy after the harm has been done.
Groets,
Simon
