SPH-135/AD
DISCONTINUED BY MANUFACTURER - SOLD OUT.
This 135mm / 5¼" unit is used in the Sterling Broadcast LS3/5a.
Featuring a mineral loaded (carbonised) polypropylene cone with a high internal damping factor, this unit offers a flat extended response with non of the large midrange peaks that plagued the majority of bextrene coned B110s.
A great replacement for a huge range speakers including various models from Mission, Castle, JPW, Rogers and others.

Used in a DIY LS3/5a project, with Morel CAT 298 tweeters and custom crossovers using ClarityCap CSAs. Super pleased with these woofers! I think they synergize well with the “live” thin-wall LS3/5a cabinets. The sound is neither bloated, nor thin, just revealing, spacious, and with very lifelike tone. I’m so happy with the results of this project and had a great buying experience with Willy’s. Thank you!!
Thanks for the review - that's a great looking project !
