The Lancetta as described by Bernd Timmermanns:
"The Lancetta exceeded all expectations. Nobody expected such an impressive
bass displayed by this slender frame. Based on a deep and cleanly structured
bass is a clear and three-dimensional midrange, finished off by a really decent
high frequency resolution. Sure, in this area the Lancetta cannot compete
with loudspeakers equipped with top-quality dome or ribbon tweeters. The attention
to detail, however, is astonishing and produced without any unpleasant harshness."...
Miracles by the Lancetta's power handling shouldn't be expected; this speaker
is well suited for a moderate volume, not for much more. The Tangband W 3-871
(pictured left) is just 9.4 cm in diameter, using a aluminium phase plug
for cooling, while the cone is made of paper.
The Tangband full range driver possesses a relatively high Q factor, meaning
that on paper a larger cabinet could be used or the bass is slightly emphasised,
similar to CT 209 With this
in-house competition Bernd Timmermanns wasn't happy. Looking for more suitable
application he came up with the logical idea to put the Tangband in a transmission
line, where relatively weak driver magnets are required. Additionally, in
this type of enclosure the Tangband operates far below resonance frequency.
To achieve a more even frequency response two Helmholtz resonators were put
into the enclosure, just above the driver. The Lancetta consists basically
only of exterior walls, since there is only one channel, ending near the base.
Our standard kit consists of:
Lancetta kit price without cabinet per unit: EUR 51,10 excl. VAT: € 42.94 / $ 47.24
Please note: Per cabinet 2 x drain pipes with
46 mm diameter and 60 mm length are needed. Available at the local hardware
store or from us for EUR 10.00 (pipe for 4 pipes / a pair of speakers).
Money saving hint: Marginally cheaper is a 1.0
mm coil instead of a 1.4 mm. As result you get a bit more kick bass and save
EUR 2.40 per cabinet.
Optional: impedance correction for valve amps:
- 1 x 15 uF audio frequency ELCO or ELCO unetched
- 1x 10 Ohm MOX10 resitor (brown-black-black)
Lancetta Medium-End kit price without cabinet per unit: EUR 63,00 excl. VAT: € 52.94 / $ 58.24
The High-End version only uses top-quality components:
- 1 x 0.56 mH cfc-14 coil instead of air core coil
- 1x 6.9 uF foil, consisting of (according to suggestion in building instructions):
2.2 uF Mundorf-Supreme MCAP in parallel to
4.7 uF Mundorf MCAP 400 V
- in addition to impedance correction (costing a mere 2 EUR)
- gold plated brass binding posts instead of spring loaded terminal
- additional 0.5 metre sealing tape
- silver plated wire 2x2,5 mm instead of copper2
Lancetta High-End kit price without cabinet per unit: EUR 103,00 excl. VAT: € 86.55 / $ 95.21
This speaker kit contains 1 x 8.2 uF MKT (=C1) instead of 6.8 uF
and instead of 2 x 22 Ohm resistors just one MOX10 with 8.2 Ohm
All other components are the same.
Lancetta AL kit price without cabinet: EUR 61,60 excl. VAT: € 51.76 / $ 56.94
