Independent shopping perspective
The Korena take
Two-way 12-inch passive PA cabinet, 65-degree coverage, fly points included. For installs and rigs that already have an amp and processing.
Strong match
Who this is for
- Fixed installs where a rack amp lives in a closet
- Bands with an existing amp rack and a mixer
- Rooms needing a tight, controlled 65-degree pattern
Consider the trade-offs
When to look elsewhere
- Anyone without a power amp — there's no amplifier inside
- Outdoor use, since it isn't weather-rated
- Solo acts wanting one box to carry and plug in
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
98 dB sensitivity, 127 dB max SPL
Efficient. It gets loud on modest amp power compared to a lower-sensitivity cabinet of the same size.
Detail 03
200/400/800 watts continuous/program/peak
Match an amp to the program rating around 400 watts per side. Sizing to peak invites blown drivers.
Detail 04
65 x 65 degree coverage
Narrow and symmetrical. Throws down a defined area rather than washing the room — good for rows, less so for wide side seating.
Detail 05
60 Hz to 20 kHz (-10 dB)
Full-range down to 60 Hz. Kick drum and low bass will want a subwoofer underneath.
Detail 06
Parallel NL4 connectors, flyable, 32 lb
Two NL4 jacks let you loop to a second cabinet. Fly points are built in for permanent hangs.
Final check

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Do I need an amplifier for this?
Yes. It's passive, so it has no internal amp. You'll need a power amp rated appropriately at 8 ohms plus speaker cable with NL4 connectors.
02Can I use these outdoors?
It isn't rated for outdoor use. Weather exposure risks the drivers and cabinet, so keep it under cover or indoors.
03Do I need a subwoofer?
It reaches 60 Hz, which covers most vocals and instruments. Add a sub if you're running kick drum, bass guitar, or recorded music.
04How many can I run off one amp channel?
Two cabinets in parallel drop the load to roughly 4 ohms nominal, with a 5.6 ohm minimum per box. Confirm your amp is stable at that load first.
