93. Rear speaker upgrade

Entry:2019.09.16 / Work:2018.06.24

Added acoustic network (for BOSE 501X shadow base box) to rear speaker (BOSE 301 woofer). The backward speaker above the head is the tweeter of the BOSE 301... this is a just extra.

Photos & Making

It looks the same, but it sounds better.

Connect the lines for the original pair of cube speakers to the rear-facing 301 full-range speakers.

Port this attenuator to the speaker box under the seat.

When I opened the back cover, there was an attenuator.

Woofer unit of BOSE 501X.

This is on the left, on the side of the sliding door.

301 full range speaker, leave it as is.
