Independent shopping perspective
The Korena take
Darkglass combines a Class-D power section rated at 900 W RMS into 4 ohms with detailed control over the signal path. The six-band graphic EQ handles broad tone shaping, while the X circuit lets you choose frequency ranges for low-end compression and treble saturation. Cabinet simulation can retain up to three virtual cabinets, and MIDI provides programmable channel switching and muting. An auxiliary input and headphone output add a self-contained monitored-playback option.
Strong match
Who this is for
- Recording chains where cabinet simulation and six-band EQ control are part of the bass workflow.
- Practice sessions using the auxiliary input and headphone output for monitored playback.
- MIDI-based stage setups needing programmable channel switching and muting.
Consider the trade-offs
When to look elsewhere
- Speaker configurations whose total load falls below the specified 2.5-ohm minimum.
- Power sources outside its 100–250 VAC, 50/60 Hz input range.
