Temperance aus Test K+T 4/2006 The finished loudspeaker featured Stereo 3/2006 (page 60, price per pair 4400 EUR) is now available as a kit at an affordable price. The kit contains the same drivers as the finished speaker.

Looking at the Temperance it becomes clear that this speaker is produced industrially: simple and carefully thought out solutions by Harald Hecken and a cabinet that is easy to assemble despite many parts. This plus high quality crossover components result in an excellent sound reproduction.

The latest Temperance version is equipped with a tweeter Scan Speak D2604-833000 (new 9/2016) that improves the sound quality quite considerably. Midrange Newtronics M17-4 and three bass drivers Newtronics BM17-8 have high quality die cast baskets.

The kit for a pair of speakers contains:

- 2 Scan Speak D2604-833000 (ab 9/2016)
- 2 Newtronics M17-4, 18 cm midrange drivers
- 6 Newtronics BM17-8, 18 cm bass drivers

Please note:
due to the four midrange and bass drivers configured in parallel we recommend to use a solid high current amplifier, since the Temperance's impedance at low frequencies falls below 3 Ohm.
