Product Descriptions

Panaray® LT 6403 and LT 9403 Full-Range Loudspeakers

The Bose® Panaray LT 6403 and LT 9403 Full-Range loudspeakers are full range, three way devices. They use a 15" woofer, a V2 mid-frequency driver and a 1.0" compression driver mounted on a 60 x 40 (LT 6403) or a 90 x 40 (LT 9403) constant directivity horn assembly. This horn assembly can be rotated 90 degrees to allow sideways placement of the speakers.

These loudspeakers can be operated in passive or bi-amplified mode.

• In passive mode, the internal passive crossover network is utilized and a single amplified signal is connected to the loudspeaker.

• In bi-amplified mode, the low-frequency and mid/high-frequency drivers are accessed through separate pins on the NL4 connectors.

Panaray LT 6400 and LT 9400 Mid/High Frequency Loudspeakers

The Panaray LT 6400 and LT 9400 Mid/High Frequency Loudspeakers are essentially the same as the LT 6403 and LT 9403 full range versions, but without the 15" woofer. They use a V2 midfrequency driver and a 1.0" compression driver mounted on a 60 x 40 (LT 6400) or a 90 x 40 (LT

9400) constant directivity horn. The horn assembly in the LT 6400 and LT 9400 can be rotated 90

degrees as in the LT 6403 and LT 9403.

Active equalization of all four loudspeakers can be provided by using the ControlSpaceTM ESP-88 or the Panaray Digital System controller which has presets for each Panaray speaker and combination of speakers. A parametric equalizer can also replicate the active equalization curves on the previous pages, along with high-pass and low-pass filters as shown.

All of these speakers have sixteen steel threaded inserts - four top, four bottom and four on each side. Threaded inserts are SAE 3/8 - 16 thread, with at least 18 usable threads.

Hanging hardware for these speakers can be purchased from ATM Flyware at http://www.atmflyware.com.
