Epic Driver

$0

Epic™ drivers deliver our trademark high-displacement, low-distortion deep bass, yet are still lighter, compact, and more affordable - all without sacrificing excellent efficiency ratings.

Driven by just a few hundred watts, these woofers kick out impressive music or movie audio, deep into the lowest octaves. And Epic packs in many of our most costly innovations like 1″ synthetic rubber surrounds, stainless steel voice coil formers and oversize spiders with our pioneering integral power leads.

Grasp our nearly nine pound FEA-optimized magnets and our overachieving Epic’s will impress even before you fire it up. Spanning 8, 10 and 12 inch sizes, the fact you invested in TC Sounds will be obvious from the first note.

What people are saying

Epic 8” – Top Notch Performer

“Bass is powerful, distortion is low and it mates easily with the full range speaker with which it is paired. It’s expensive, but worth its price….”

Mr. Speaker – PA, USA

Epic 10” – Big Sound Little Package

“Wow! This thing ROCKS! Best of all it is tiny. Pound for pound I would put this up against the store-bought Paradigm Servo 15 I have in my media room.”

Prometheus – LA, USA

Specifications

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.
