Blue Start 5 TQWT is a floorstanding with Omnes Audio and LPG drivers. The initials TQWT are an abbreviation for Tapered Quarter Wave Tube. This is a mixture of transmissionline loudspeaker an bass reflex loudspeaker. Blue Start 5 TQWT has been developed by Blue Planet Acoustic.
The crossover consists of a 2nd order high-pass filter (12 dB per octave slope) for the tweeter and a 2nd order low-pass filter for the woofer. A parallel RC circuit is smoothing the impedance of the woofer.
The frequency response of this speaker is linear. The decay spectrum is nearly perfect. At low volume, i.e. 85 dB at 1 m, the nonlinear distortions are lower than 0.5% above 300 Hz and rarely exceeds 1% at 95 dB at 1 m .

The high-end kit comes with an ClarityCap SA capacitor instead of an Audaphon MKP capacitor. Two electrolytical capacitors are replaced by foil capacitors. All inductances are baked varnished coils 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.

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).
If you prefer to mount the crossover components on a 140 x 102 mm universal PCB instead on wood:

We recommend one board per kit (two boards for a speaker pair)
