GENERAL DESCRIPTION
The Q 115 is a full-range, 2-way bass reflex loudspeaker system. Equipped with a single neodymium 15” woofer (3” coil) and a 2”
compression driver (3” coil) coupled to a constant directivity rotable horn with 60°H x 40°V coverage. The outstanding performance of
this speaker depends not only on the use of high quality transducers but also on precise design of passive cx-over. Designed for high
sound levels (131.5 dB SPL), the Q 115 is perfect for every type of situation, from disco to concert venue.
With its controlled dispersion, low distortion and bass extension, the Q 115 is ideal in fixed installations in night clubs, pubs, theatres
or sound reiforcements in live performance.
The cabinet is constructed fro 18mm birch polywood finish in a durable and scratch resistant paint. Dual-mode passive filter with
facility for full-range or bi-amp operation with external processing of the signal.
4M10anchoring points for suspended installation and full compatibility with dedicatedmounting hardware.
The connector panel’s have dual Neutrik NL4 speakon for reliable input and loop through connections.

The 2-way full range loudspeaker shall incorporate one 15” LF transducer
and a 2” HF driver.
The HF driver shall be loaded on a rotable horn with a nominal coverage
pattern of 60° (H) x 40° (V).
An internal dual-mode passive filter with HF protection shall provide
acoustical crossover and system equalization.
Input panel shall easily change from passive to biamp operation via internal
connector.
System frequency response shall vary no more than +/- 6dB from 45Hz to
18kHzmeasured on axis.
The loudspeaker shall produce a sound pressure level (SPL) of 131.5 dB on
axis at 1 meter.
It shall handle 400 watts of amplifier power long term (AES standard) and
shall have a nominal impedance of 8 ohm.
It shall be constructed of 18mm Baltic birch wood with internal
reinforcement.
Input connectors shall be two NL4 speakon.
