BMB CSP-612 High-Power Home Karaoke System with AC S-800 & CH-300
The BMB CSP-612 High-Power Home Karaoke System is designed for larger home KTV rooms and entertainment spaces where a smaller 10-inch system may not provide enough scale, bass, or output.
This package combines BMB CSP-612 12-inch Professional Series speakers, the AC S-800 800W × 2 karaoke DSP amplifier, and the AC CH-300 dual wireless microphone system.
With larger 12-inch speakers and substantial amplifier headroom, the system delivers stronger music impact, clear vocal projection, greater dynamic range, and more room-filling sound, while keeping the equipment setup simple and easy to operate.
Complete Karaoke System
- BMB CSP-612 12″ Speakers – Pair
- AC S-800 800W × 2 Karaoke DSP Amplifier

Recommended Room Size
Recommended Room Size: approximately 300–500 sq ft (28–46 m²)
This system is especially well suited for:
- Large living rooms
- Dedicated home KTV rooms
- Large entertainment rooms
- Private karaoke rooms
- Private dining and entertainment spaces
- Restaurant karaoke rooms
For a typical enclosed room with standard ceiling height, one pair of CSP-612 speakers can provide powerful music, clear vocals, and strong coverage throughout the listening area.
Rooms around 500–600 sq ft may also work depending on ceiling height, room layout, speaker placement, and desired volume.
For very large open-concept spaces or rooms requiring more even coverage, additional speakers and amplification may be recommended.
BMB CSP-612 – 12″ Professional Series Karaoke Speaker
The BMB CSP-612 is a 12-inch two-way bass-reflex speaker from BMB’s Professional Series, designed for applications where strong vocal reproduction and higher output are required.
Speaker Specifications
- 12″ Woofer
- Two-Way Bass-Reflex Design
- 400W Continuous Power
- 800W Program Power
- 1600W Peak Power
- 8Ω Impedance

The larger 12-inch woofer gives music more weight and scale, while the professional-series design keeps vocals clear and present.
For a large home KTV room, the difference is easy to hear: music feels bigger, bass has more authority, and the system maintains its energy when the volume increases.
AC S-800 – 800W × 2 Power with Built-In Karaoke DSP
The AC S-800 delivers:
800W × 2CH @ 8Ω
providing substantial amplifier headroom for the CSP-612 speakers.
The S-800 also integrates advanced karaoke DSP processing, eliminating the need for a separate DSP processor and power amplifier in most home installations.
Key functions include:
- 15-Band Microphone PEQ
- 7-Band Music PEQ
- Echo & Reverb
- 4-Level Feedback Suppression
- Main Output DSP
- Center Output Processing
- Subwoofer Processing
- HPF / LPF Control
- Output Delay
- 6 Programmable Sound Presets
- 4.3″ Touchscreen
- Bluetooth 5.0
- PC Tuning
This gives the system the power of a larger karaoke setup while keeping daily operation much simpler.
AC CH-300 Dual Wireless Microphones
The AC CH-300 provides two wireless handheld microphones for karaoke, duets, family gatherings, and parties.
Combined with the S-800’s dedicated microphone EQ, Echo, Reverb, and feedback suppression, vocals can be adjusted for different singers and room acoustics.
The result is clearer and more comfortable vocal performance without requiring users to understand complicated professional audio equipment.
Bigger Sound for a Bigger Home KTV
This system is a strong choice for customers who have a large living room or dedicated entertainment room and want karaoke to feel substantially bigger than a typical home setup.
The 12-inch CSP-612 speakers provide more scale and impact, while the S-800 supplies enough power and DSP control to keep the system clean and controlled.
At home, you can expect:
- Powerful room-filling music
- Clear and focused vocals
- Stronger bass and musical impact
- Greater dynamic range
- Smooth Echo and Reverb
- Detailed microphone tuning
- Enough output for larger parties and gatherings
- A more immersive KTV-style experience
This is especially suitable for customers who want the sound of a serious dedicated KTV room without building a large rack of separate processors and amplifiers.
Powerful, but Still Simple to Operate
One of the advantages of this package is its simplicity.
Instead of using a separate karaoke DSP processor and power amplifier, the AC S-800 combines both functions in one unit.
A typical setup is:

BMB CSP-612 Speakers
The CH-300 wireless microphones connect directly into the karaoke system.
This keeps the installation cleaner while still providing advanced tuning control.
Easy to Expand

A compatible subwoofer can be added for customers who want deeper bass, while larger installations can be expanded with additional speakers and amplification when more even room coverage is required.
