i don't think i was hammering it. i have another pair of acoustas and i don't think i was playing as loud as i have before. before you ask; one of the other pair went intermittent - the solder joint on the cone seems to have gone it will play if you touch the joint but stops when you let go - i cannot get it to solder i think i maybe I need an aluminum iron and solder. but back to the other lowther i was hoping that it was just rubbing inside the gap, after all if i had blown it it would not work at all?
Older Lowthers chassis could be adjusted to center the voicecoil
Dont know about the new ones
But when you say #acoustas# I guess they are quite old
How old are the drivers
xperts may know how to improve with reconing
Do you have any pictures, might help
btw, have you ensured its not something else, by say connecting to other amp channel

distortion is in the bass. all bass lines sound very, very fuzzy. mid and treble dont appear affected. i must say that the driver was not distorting when i got it...well certainly not as bad as now which is extremely obvious. i have attached pictures of the driver.
the guy i bought them from says that they where reconed at some stage. but it appears to me that the surround is facing the wrong way...is it? all the other lowthers that i have seen have a inverted surround when viewed from the front

Lowther America website used to have description of alignment process .I don't see it now but I'm sure it's there somewhere. Contact Ion and he'll help you out . It's not that difficult and I aligned my DX4 without any problem. You just cut a few strips of tick paper , lose the cone basket, stick the paper shims carefuly in the VC gap between center pole and VC coil around the perimeter so they "force" symetric position of VC assy in the gap, tight the screws, carefuly remove paper shims and check pushing gently cone if there is any rubbing . Good luck!
+1, can't say i did it with a lowther but have with other vintage small gap drivers.
btw lowthers have had a long reputation as notorious for this. referenced in sound practices issue 12, "lowther: another opinion marc s. wauters pp. 20 - 25
not sure if i can put the following here and please remove if i can't. another thing mentioned was a scratch shortly after use due to the former's inner winding being off of the vc. in the gap.
i suggest getting a copy, it's a very informative read telling which older models to avoid and why, problems and fixes, etc.

thanks for the advice limono. i cannot find any reference to realigning on the lowther america site or an Ion...but your description makes sense. just one question when you say "lose the cone basket" do you mean to remove all the little screws that sit in the circumference of the front plate? or the larger four screws that hold the magnet?
Would this help?
Refurbishing the Lowther
But, it may be something more serious than misalignment or dirt in the gap (which usually cause higher freq scratching noises, I think). The driver may require recone, but I no expert.
