The RF-35 uses a 1-inch titanium dome compression driver tweeter for the high frequencies, loaded by a 6-inch square 90 x 60-degree Tractrix Horn molded into the front of the enclosure. The horn raises the driver's efficiency and controls its radiation pattern to minimize detail-blurring reflections from walls, floor, and ceiling. Dual 6-inch Cerametallic cone woofers with rigid, low-resonance castpolymer frames generate powerful, dynamic bass. All drivers are magnetically shielded to prevent interference with direct-view television sets. The RF-35 also has a flared rear port to minimize turbulence noise.

The RF-35's crossover network ensures life-like performance with its top-of-the-line internal wiring, polyester film-type capacitors and an air-core inductor all mounted on a high-quality fiberglass epoxy circuit board. These premium components ensure lifelike performances. The speaker features two pairs of binding posts, which are linked with jumpers for normal wiring. Removing the jumpers allows the speaker to be bi-wired. The speaker's floating grille minimizes diffraction, and its feet can be fitted with rubber pads or spikes.
