Long Tall Sally Geviertelt is a two way compact speaker.

Long Tall Sally Geviertelt is a bass-reflex cabinet loudspeaker with drivers of Monacor .

The kit is delivered with the following drivers:
- a Monacor MPT-165 tweeter
- two Monacor SP-60/4 woofers

The loudspeaker has been developed by Bernd Timmermanns.

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.

Our kit consists of

  • 2x Monacor SP-60/4
  • Monacor MPT-165 piezo tweeter
  • 2x Bass reflex tube HP50, 50x145 mm, black
  • 0,5x PE sealing tape, 5x2 mm, 7.5 m

Kit without cabinet, price per speaker   EUR 132,00 excl. VAT: € 110.92 / $ 116.47

In this kit are no plans for the cabinet included. There is only a recomment for the cabinet sizes and the bass reflex port data.

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 Monacor MPT-165 are of type polypropylen (MKP) Audaphon MKP CAP Superior.

Kit with high-end-crossover without cabinet, price per speaker   EUR 151,00 excl. VAT: € 126.89 / $ 133.24

In this kit are no plans for the cabinet included. There is only a recomment for the cabinet sizes and the bass reflex port data.

universal PCB

If you prefer to mount the crossover components on a 159 x 127 mm universal PCB instead on wood:
Universal PCB RA160, order no.. str-RA160, price per unit:   EUR 5,90 excl. VAT: € 4.96 / $ 5.21
We recommend one board per kit (two boards for a speaker pair)
