Test recordings of speech sample and sin sweeps made in the recital hall (see photo examples) using 2 Schoeps MK5 in omni. Each is recorded in the same position (mics 15 feet from source) with constant mic gain. Genelec 8030 and live speech included for reference.

Exciters: DAEX-25 5 Watts RMS
Amplifier: Fosi Audio V1.0G 2 Channel Class D 50W x 2
(https://www.fosiaudio.com/product-support/2-channel-amplifier/v1.0g/)

NOTE: the DAEX-25 used in these recordings is underpowered for the output level, leading to distortion. For the final installation will be using DAEX32QMB-4 Quad Feet Mega Bass Exciter (40 Watts RMS).
