Care and Cleaning

To maintain speaker appearance, we recommend wiping them down with a clean damp soft cloth. To clean dust from the grille cloth, use a vacuum with a brush attachment.

Features

At the heart of the TK Series speaker system is a proprietary fiberglass cone bass/midrange driver (speaker). The fiberglass cone resists flexing better than typical speaker cone materials, thereby providing highly articulate and accurate reproduction of the audio signal. The stiffness and lightweight characteristics of fiberglass, combined with the driver’s large motor structure, give the drivers high excursion capability. This high excursion capability prevents compression or distortion of the audio signal, which leads to higher overall sound quality. The smaller drivers and tweeters in the TK speaker system are video shielded to cancel any stray magnetic fields which may cause interference with video equipment such as CRT televisions.

A high quality soft dome tweeter is used for high frequencies in the TK Series. Higher power handling is achieved through the use of Ferro Fluid® liquid cooling in the tweeter. To protect the tweeter against being over driven, a Polyswitch (a DC current limiting device) is incorporated in the crossover network.

Each TK Series model features an extensive crossover network. The use of these high quality crossover networks allows each speaker to operate at its optimal performance. Steep acoustic crossover slopes are used to integrate the drivers; the use of steep crossover slopes allow higher power handling, minimizes driver interaction irregularities, and maximizes the ability of each driver in their respective band of frequencies. Large 5-way binding posts ensure a good, solid electrical connection to these crossover networks.

The TK Series cabinets are constructed of ¾-inch medium density fiberboard because of its inert properties, thereby preventing sound coloration due to cabinet diffraction. The thickness of the front baffles also prevents excess acoustic radiation.

Attaching Speaker Wires

When using a banana jack to attach speaker wires to the binding post terminals, remove the black and red plastic protective inserts from the terminals. To do this, loosen the binding nut from the terminal by turning the nut counter- clockwise until the nut is completely removed from the terminal. Remove the plastic inserts by pulling them straight out, then replace the nut to the terminal and turn clockwise. Insert the banana jack into the hole provided in the top of the terminal, and then continue to tighten the nut until secure. Repeat for the other speaker wire(s) as necessary.
