Factory-Location Upgrade
Fitment, impedance, sensitivity and the factory signal matter more than the logo on the cone.
FOCAL PROJECT ARCHIVE • NOT A CURRENT SUPPORTED NEW-PRODUCT LINE
SMS has documented Focal systems in the project archive, but Focal is not a current new-product line at SMS. A one-off open-box Focal item may still appear in closeout inventory; that does not mean we are carrying the current Focal lineup.
The useful part of these older builds is the system design: speaker placement, mounting, power, DSP, factory integration and tuning all had to work together.
Fitment, impedance, sensitivity and the factory signal matter more than the logo on the cone.
A woofer and tweeter still need rigid mounting, the right passive or active crossover plan and amplifier power that matches the system.
Adding a midrange can improve control over the front stage, but it also adds mounting, amplifier-channel and DSP requirements.
Independent channels give us control of crossover, level, delay and EQ for each speaker section when the installation supports it.
Flexible mounting, air leaks, reversed polarity, unsafe crossover settings, poor gain structure or a heavily processed factory signal can hold back any speaker. We build the physical installation and signal path first, then use tuning to finish the system.

This documented SMS system used Mosconi amplification with a Focal K2 speaker system.

This older SMS speaker-installation proof is kept for reference because the mounting and system lessons still apply.

Tell us the vehicle and the goal—better-than-factory sound, a sound-quality front stage, active three-way control, OEM integration, more output or full custom fabrication. We will build around the current SMS-supported brands instead of trying to recreate an old archived parts list.
