Long Tall Sally is a two and a half way floorstanding speaker.

Long Tall Sally 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 midrange / bass drivers
- 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 mids-woofer.
- 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 medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are below 1,2% above 300 Hz.

Our kit consists of

  • 4x 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
  • 0,5x Damping Sonofil 100 x 35 cm for 20 litres
  • Audaphon Damping 10, 970 x 470 mm, adhesive
  • Binding Post PK31, gold plated (one pair, red and black)
  • 3m Speaker cable 2x1.5 mm2, transparent
  • 2,5x Pan screws 4x20 black, torx, 8 pieces

Kit without cabinet, price per speaker   EUR 166,00 excl. VAT: € 139.50 / $ 154.84

For a better power rating we deliver a 1,0 mm air coil for L1 instead of a 0,7 mm air coil and for R1 a MOX10 resistor instead of MOX5.

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 190,00 excl. VAT: € 159.66 / $ 177.23

For a better power rating we deliver a 1,0 mm air coil for L1 instead of a 0,7 mm air coil and for R1 a MOX10 resistor instead of MOX5.

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 3,28 excl. VAT: € 2.76 / $ 3.06

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.. I-2766, price per unit:   EUR 5,10 excl. VAT: € 4.29 / $ 4.76
We recommend one board per kit (two boards for a speaker pair)
