Tyne is a two way compact speaker.

Tyne is a bass-reflex cabinet loudspeaker with drivers of Celestion .

The kit is delivered with the following drivers:
- a Celestion FTX0820 coaxial driver

The loudspeaker has been developed by Dennis Frank and Daniel Gattig.

The crossover consists of:
- a 2nd order high-pass filter (12 dB per octave slope) for the tweeter-part.
- a 3rd order low-pass filter (18 dB per octave slope) for the woofer-part.

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 0,8% above 300 Hz and doesn't exceed 2,5% at 95 dB at 1 m between 300 and 15000 Hz.

Our kit consists of

Kit without cabinet, price per speaker   EUR 228,10 excl. VAT: € 196.64 / $ 230.07

Kit with high-end crossover

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 Celestion FTX0820 tweeter part are of type polypropylen (MKP) Clarity-Cap ESA 630 V.

Impedance correction

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 8,04 excl. VAT: € 6.93 / $ 8.11

universal PCB

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 150x115 mm, tin plated, price per unit:   EUR 4,58 excl. VAT: € 3.95 / $ 4.62
We recommend one board per kit (2 boards per speaker pair)
