2241 has a relatively low motor force product (BL*BL)/Re) it may "wheeze".
hi neo dan
can you please explain "wheeze"
english is not my mother language and the translation doesnt help
thank you
Dan,"wheeze" is Art's term, he tried another driver with low motor force, the Kappalite 3015LF
The sound seems compressed or restricted, no balls
I don't recall using the word "wheeze" in describing the effects of low motor force, and have not actually tried the 3015LF.
In describing the sound of the Keystone I wrote: "The very stiff cones of the Lab 12 and the B&C18SW125-4 can take (that) stress and sound clean, when pushed hard the 4015LF (and probably the lighter 3015LF even more) sounds a bit distressed." The "probability" was speculation after looking at a distortion test JBell performed on his SS15 using 3015LF.
By "distressed", I meant distorted, as in well over 10% harmonic distortion at relatively low drive levels, bad enough I didn't bother measuring the distortion when pushed hard.

Making me doubt my memory, I don't need any help with that Art!
Apparently the following was about the 4015, another with lowish motor force BL²/Re...
Almost everything is WEAK when compared to the 18SW115
Subjectively, with the same drive level the Keystone using the B&C18 seems a bit more “punchy”, more stuff falling off shelves in the shop, and more feel in the feet of the sidewalk vibrating outside. It takes full power from a bridged Crest CC2800 effortlessly, while the 15 seemed a bit “wheezy” at a lower drive level, the 2x12 in between.
Sorry ..Making me doubt my memory, I don't need any help with that Art!

We'll let it slide this time, next time however we're going to have to start taking that thinko' ginkgo...
are those 18sound 18nlw9600 ?Well well well. What do we have here
lol... its far from perfect, I had to pull the front panel about 3/8 of an inch in when attaching side 2 (got off square). THankfully clamps helped me do that.
The braces are me, a handful of explitives and a compount mitre saw lol. as you can see I broke that back brace into 2 pieces (2nd piece not pictured) to make the cuts easier.
