Cumulus Maxx is a three way floorstanding speaker.
Cumulus Maxx is a bass-reflex cabinet loudspeaker with drivers of Redcatt .
The kit is delivered with the following drivers:
- a Redcatt CX8.01X8 coaxial driver
- two Redcatt Exclusive 8 woofers
The loudspeaker has been developed by Bernd Timmermanns.
The crossover consists of:
- a 3rd order high-pass filter (18 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 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% above 200 Hz.

Kit without cabinet, price per speaker EUR 549,00 excl. VAT: € 461.34 / $ 493.64
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 Redcatt CX8.01X8 are of type polypropylen (MKP) Mundorf MCAP EVO Öl 450 V.

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 17,80 excl. VAT: € 14.96 / $ 16.01
If you prefer to mount the crossover components on a 159 x 127 mm and two 140 x 102 mm universal PCB instead on wood:
Universal PCB RA160, order no.. str-RA160, price per unit: EUR 5,90 excl. VAT: € 4.96 / $ 5.31
Universal PCB RA140, order no.. str-RA140, price per unit: EUR 4,20 excl. VAT: € 3.53 / $ 3.78
We recommend one board RA160 and two boards RA140 per kit (four boards RA140 and two boards RA160 for a speaker pair)
