Denovo EOS-8S

Manufacturers Info

Brand: Denovo

Model: EOS-8S

Style: Elliptical

Coverage (H x V): ----

Minimum Frequency: ----

Throat: 1"

Mounting Type: 1-3/8"-18 TPI

Dimensions: 7.8" W x 5.85" H x 3.25" D

Additional Notes:

This waveguide is a larger version of the EOS-6S, it was never used in a design.

The Celestion CDX1-1731 did not screw into the threads so the Blast King driver was used instead.

Measurements:

Test Notes: Off axis and polars measured using a Blast King compression driver.

Mic distance 1m, measurements gated at 5ms and are smoothed at 1/48 Octave.

Final Notes:

Dispersion pattern of this waveguide appears to be roughly 90 H x 75 V with some narrowing at the top end. I would say the loss of pattern control starts just above 2000hz horizontally and 3000hz vertically. Minimum usable frequency should be well under 2000hz.
