T-Desk 315 is a compact speaker with a fullrange driver.
T-Desk 315 is a bass-reflex cabinet loudspeaker with drivers of Tang Band.
The kit is delivered with a Tang Band W3-315 fullrange speaker
The loudspeaker has been developed by Bernd Timmermanns.
The crossover consists of two RCL circuits in series to the fullrange driver.
The frequency response of this speaker is linear at 20 degrees off axis. The decay spectrum as shown in the waterfall diagram is free of any disturbing resonance. At a volume of 80 dB or 90 dB at 1 m, the nonlinear distortions are mostly lower than 1% above 300 Hz.

Kit without cabinet, price per speaker EUR 75,00 excl. VAT: € 63.03 / $ 72.48
The high-end kit comes with MKP capacitors for the fullrange driver. The inductances for the full range loudspeaker are baked varnish air core coils 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.

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).
If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:
Universal PCB RA140, order no.. str-RA140, price per unit: EUR 4,20 excl. VAT: € 3.53 / $ 4.06
We recommend two boards per kit (four boards for a speaker pair)
