Installation Dimensions
Wire Configurations
Dual voice coil - Series: 2Ω + 2Ω = 4Ω
Top Assembly The motor and top assembly are shipped in separate boxes. Assembly screws and a hex key are included with the motor to bolt on the top assembly. DO NOT REST TOP ASSEMBLY ON VOICE COIL. Install the top assembly slowly onto the motor to avoid scraping or scratching the coil against the steel gap-plate. The TC Sounds detachable top assembly makes potential repairs a simple five minute process. This proprietary procedure is by far the easiest and fastest way to recone or repair a broken, damaged or destroyed driver. The entire frame with all of the soft-parts can easily detach from the motor and be replaced without glue, shims or any risk of unaligned coils or user error. The top assembly should fit snug over the steel gap-plate. Hand tighten the hex screws with the included hex key and use the included locking washers to prevent screws from loosening.
Dual voice coil - Parallel: 2Ω || 2Ω = 1Ω
Warranty Includes: • • • • • • • •
All manufacture defects All obvious cosmetics Improperly glued surrounds, suspensions, formers or misaligned coils Detached or unglued surrounds Broken cones from any forces from the driver itself not related to the impact of bottoming out the voice coil Voice coils that collide with the gap or t-yoke under normal conditions where no preexisting abuse has occurred Alignment of the voice coil or top assemblies/motors which don't fit each other Motor glues
Not Covered By Warranty: • • • • • • • • • •
Misuse or over excursion Thermal abuse to the voice coil or glues around the voice coil Thermal abuse to the lead wires on the spiders Mechanical damage due to over excursion or excessive acceleration Dents in the cone from bottoming out the driver or inadvertent force Spider sag due to gravity in a down or up firing position for long periods of time Damage due to moisture Shipping damages Cosmetic damage Consequential damage on other components
