Axis Driver


Redefine music and theater sound  in tight spaces with TC Sounds Axis™ woofers.

The  Axis line  features high motor force, long excursion and very high power handling.  The result is world-class power, clarity and depth for any mobile cabin, theater or studio application where small enclosure size and reference sound pressure levels are demanded.

TC Sounds Axis drivers start with a whopping 40+ pound motor, add pro-grade flat-wound 8-layer conductor voice coils and triple reinforced stainless steel formers.  All this technology work harder and smarter than lesser woofers.

Finally, room left over to enjoy music again.

What people are saying

Excellent performer

“I use a pair of these little monsters in a stereo system crossed over at 60hz to my full range main speakers. I use very high end Von Schweikert speakers so needed something to add that last octave and sound good ….The only subs that I own that are better are my LMS Ultra’s in the home theater.”

Best woofer ever

“If you are searching for absolute lows, with little to no distortion, and high power handling, then your search has ended.… Special effects hit hard, and mixing at sub frequencies (20-35hz) is MUCH quicker, as I can hear the actual tones, and not the sounds of the cone flapping…. The price, worth every penny.”

Standard small parameters, power and motor specifications listed below. These parameters are only a guildline to system design and expected response. Some of the parameters such as the Qts will shift with heat or excursion by more than 20%. There is no reason to model or expect exact constant parameters because of these natural non-linear shifts.
