Ajalon is a three way floorstanding speaker.

Ajalon is a bass-reflex cabinet loudspeaker with drivers of Morel .

The kit is delivered with the following drivers:
- a Morel TSCT 1044 tweeter
- a Morel TSCM 634 mids driver
- two Morel TICW 958 FT woofers

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.
- a band pass consisting of a 2nd order high pass filter (12 dB per octave slope) and a 3rd order low-pass filter (18 dB per octave slope) for the mids-woofer.
- a 2nd order low-pass filter (12 dB per octave slope) for the woofers.

The frequency response of this speaker is perfectly linear.

The decay spectrum as shown in the waterfall diagram is exemplary, free of any disturbing resonance.

At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are below 0.5% above 400 Hz and doesn't exceed 1% at 95 dB at 1 m between 300 and 15000 Hz.

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 Morel TSCT 1044 are of type polypropylen (MKP) Clarity-Cap CSA 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 4,20 excl. VAT: € 3.53 / $ 3.81

universal PCB

If you prefer to mount the crossover components on a universal PCB instead on wood
PCB 220x155 mm, order no. I-8805002, price per unit:   EUR 11,80 excl. VAT: € 9.92 / $ 10.71
We recommend one board per kit (2 boards per speaker pair)
