5.25" driver, 90Hz low-end limit

1/8
Independent shopping perspective
The Korena take
Compact 150W powered speaker with a 5.25" driver and a two-channel mixer built in. For small rooms, spoken word, and low-volume acoustic sets.
Strong match
Who this is for
- Solo acoustic act in a coffee shop or small bar
- Presenter needing a mic and playback in one box
- Mic-stand mounted monitor for a keyboard or backing tracks
Consider the trade-offs
When to look elsewhere
- Bands needing kick drum or bass reinforcement below 90Hz
- Outdoor gigs or rooms over about 100 people
- Anyone wanting stereo from a single unit
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
110dB continuous / 120dB peak at 1 meter
Loud enough to cover a room of conversation, not loud enough to carry over a live drummer.
Detail 03
Two mic inputs plus stereo line input
Runs a mic and a phone or laptop at once without a separate mixer in front of it.
Detail 04
Mic-stand socket on the bottom of the cabinet
Goes up on a standard stand at ear height instead of firing at your knees from a tabletop.
Detail 05
7.6 lb, 8 x 11.2 x 6.8 inches
Carries in one hand with the top handle. Fits in a backpack or a car footwell.
Detail 06
Class-D amp with convection cooling
No fan, so nothing hums under quiet passages or between songs. Runs on wall AC only.
Final check
Know before you order
- 01No stand, mic, or cables included — budget for those separately
- 02AC power required; there is no battery option
- 03One speaker gives mono coverage; a stereo pair means buying two
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this for a full band?
Not for drums or bass. The 5.25" driver rolls off around 90Hz. It works as a vocal or acoustic instrument speaker in a quiet room, or as a personal monitor.
02Do I need a mixer with it?
No. It has two mic inputs with gain and a stereo line input, plus three-band EQ. A mic and a phone plug straight in.
03Will it mount on a speaker pole?
It mounts on a mic stand via the socket on the bottom with the supplied adapter. It is not built for a standard 35mm speaker pole.
04How many people will it cover?
Comfortably a small room — a cafe, a classroom, a corner of a bar. Past roughly 100 listeners or outdoors you will want a larger powered speaker.
