Ultra Subwoofer Kit

Starting at   $1,300.00

The Ultra Subwoofer Kit will increase the low frequency impact and resolution of powered subwoofers significantly, helping them keep up with the rest of the system, particularly if it is already linked with Transparent Ultra interconnects, Ultra speaker cables, and Transparent Premium HDMI cables.

The kit consists of a single channel of Ultra RCA Interconnect with a network that provides superior bass frequency energy transfer, a gold-plated RCA Y adapter, and a 6″ RCA terminated piece of Ultra RCA Interconnect without a network. The 6″ interconnect spans from one of the RCA inputs on the Y adapter to the second RCA subwoofer input. Using the short interconnect jumper improves subwoofer sound quality.

Ultra Subwoofer Kit transfers more low frequency energy than Super Subwoofer Kit due to heavier solid OFHC conductors and a network design with tighter-tolerance parts and construction.

Ultra Subwoofer Kit is upgradeable through an authorized Transparent dealer to a subwoofer kit at Reference level and above.
