CT 308 (Empor SL) is a two way floorstanding speaker.
CT 308 (Empor SL) is a TQWT-loudspeaker with drivers of Omnes Audio .
The kit is delivered with the following drivers:
- a Omnes Audio T25 H tweeter
- a Omnes Audio LoCo 6.1 woofer
The loudspeaker has been developed by BaurAkustik.
The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofer.
The frequency response of this speaker is nearly linear.
The decay spectrum is nearly perfect.
At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0,3% above 400 Hz and doesn't exceed 0,7% at 95 dB at 1 m between 300 and 15000 Hz.

Kit without cabinet, price per speaker EUR 120,00 excl. VAT: € 100.84 / $ 120.00
The high-end kit is delivered with baked varnish air core coils on important parts of the crossover for minimizing microphonic effects. - The current flow through the coil creates a magnetic field which sets the reel of wire in motion. This motion induces a voltage in the coil which adds itself to the signal. The stiffer the reel of wire is, the less the signal will be altered. The capacitors for the Omnes Audio T25 H are of type polypropylen (MKP) Clarity-Cap SA 630 V.

If you want to use a valve amplifier with this speaker an impedance correction should be employed. In this case the component quality is less important; therefore, we offer only one kit (upon request higher quality components are available).
Price per impedance correction for one speaker, to be mounted on a small wooden board. EUR 15,20 excl. VAT: € 12.77 / $ 15.20
If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 150x115 mm, tin plated, price per unit: EUR 4,70 excl. VAT: € 3.95 / $ 4.70
We recommend one board per kit (2 boards per speaker pair)
