L = 483 mm
P = 453 mm
consumer load 8 ohms = 1000W
Likes:
- The filter to 160Hz pass-bas/haut
- The input level selector (775mV/-10dB; 1V/0dB; 1.44V / +4 dB)
- The mode (stereo, parallel or bridged)
- Connections XLR / Speakon
- The Dynamic Bass (103dB 100dB against category)

I dislike:
- Weight 33kg announced on the record but ~ 20-25kg on the scales (!?)
- The integrated limiter and multiprotection that does not trigger!
- The sound of two fans
- No ventilation grille on the front, only on the sides and rear
In terms of reliability I use it for a subwoofer that works every week -60/-20dB, no problem.

The price / quality ratio is good for € 359. After testing a good sub, frequencies below 60Hz are very limited, but hopefully stronger and more dynamic over the 80Hz.

I compared it to a Yamaha P5000S: the Yam to over fishing in the lower and better Deffinitions everywhere. The SLX is mainly used in the bass.
