Indeed! Even Sony's mobile audio coax's were built like tanks and performed well enough that after my cache of used Motorola, etc., components dried up it's all I would use to replace vehicle speakers and DIY inexpensive kid's rooms, apt., etc., speakers.

I still have one pair of 6" coax that have frozen up over time, but with wintergreen having skyrocketed in price way more than inflation, doubt I'll try to soften them up unless something cheap will do it.

Is an elliptical oblate spheroid or super elliptical oblate spheroid not an 'OS' profile?
