Vance Dickason’s

LDC6 Home Theater System

Thank You….for purchasing the #300-655 Home Theater System. This system was designed by

V ance Dickason and optimized using the sophisticated Linear X LMS/LEAP speaker simulation
software. All aspects of the design are thoroughly discussed in the Loudspeaker Design Cookbook
(6th. Edition). The systems left, center and right speakers utilize the exact same drivers to maintain
identical timbe content for the front of the home theater system. Because center channels are usually
placed on top of TVs, its driver layout is acoustically oriented for horizontal placement. The system
also features unique dipole satellite speakers that add realism to Dolby Digital movie soundtracks.
The #300-655 is perfect for small to medium sized home theater rooms and comes in kit form. This kit
can easily be assembled in a couple of hours. We recommend using the #300-739 10" Titanic
Subwoofer with this Home Theater System. Also designed by V ance Dickason, the 10" Titanic

Subwoofer produces quick, accurate and powerful bass.

3) Crossover Assembly

Warning!! The correct assembly and wiring of the crossovers is critical to the proper operation of this home

theater system. In a worst case situation, an improperly wired network can damage your receiver or amp­lifier! Please double and triple check all values and wiring before installing the crossovers in the cabinets.

Tips on assembling the crossovers.

1. Place or “layout” all components on the boards before gluing down. Use the 4" x 6" boards for the left,
center and right crossovers and the 4"x 5" boards for the satellites. The satellite crossovers are on two
boards, one (1) board for the woofer (low pass) and one (1) board for the tweeter (high pass). Each
satellite speaker will need one of each.
