K40 PRO 380W High-Power Stage Combo Amplifier – Dual DSP Professional Monitor Speaker for Band Gigs, Large Live Shows & Outdoor Events
The W-KING K40 PRO is an upgraded high-power professional combo stage monitor amplifier built for medium-sized live band performances, outdoor stage events, wedding receptions and large-scale karaoke parties. Equipped with dual woofers, eight tweeters, dual DSP sound chips and five independent audio channels, it outputs powerful wide-range sound with ultra-precise frequency tuning, while its massive 21700 battery pack with charge-while-playing function supports all-day off-grid professional performances.
Powerful 380W Three-Way High-Fidelity Sound System
Delivering a peak power output of 380W, the K40 PRO upgrades to a dual 8-inch woofer configuration, generating deep, punchy, distortion-free bass that fills medium-sized venues with rich low-frequency resonance for rock, pop, EDM and full band performances. Eight premium 2.5-inch tweeters evenly spread mid-high frequency sound across a wide listening area, restoring crystal-clear vocal harmonies, guitar riffs and percussion details without treble harshness. Matched with a tilted wedge monitor cabinet design, this multi-driver setup provides both powerful audience-facing playback and clear performer self-monitoring, separating bass, mid and treble frequencies perfectly for layered, studio-grade sound at maximum volume.
Extra-Large 21700 Battery Pack with Charge-While-Playing
Powered by a heavy-duty 22.2V 12000mAh lithium battery constructed from durable 21700 cells, the K40 PRO offers industry-leading extended playback time for all-day outdoor events with no fixed power supply. Its core charge-while-playing feature lets you recharge the speaker during ongoing performances, eliminating the risk of power cut-offs during concerts, wedding live sets and multi-hour festival shows. The high-voltage stable power supply maintains consistent full-volume output throughout long performances, with no volume drop or tone degradation.
Stage-Grade Full Professional Functional Suite
Loaded with advanced performance-focused hardware for professional musicians and event hosts:
- 5 independent channel inputs: Expandable dedicated jacks for multiple microphones, acoustic/electric instruments, backing music and auxiliary broadcast audio, supporting full band simultaneous connection and separate volume/tone control per channel
- Premium professional control panel: Independent physical adjustment knobs for master volume, bass, treble, microphone reverb, echo and channel gain, allowing precise real-time sound tuning for any venue acoustic condition
- Dual DSP sound processing chips: Dual independent DSP modules automatically optimize frequency division, suppress background noise and reduce playback distortion, greatly improving dynamic response for live vocals and instrumental performances
- OTG lossless live streaming recording: Built-in high-fidelity sound card transmits clean studio-quality audio to mobile devices and computers, ideal for recording live band performances, concert live streams and original cover creation
- Dual UHF wireless microphones included: Long-range anti-interference wireless microphones support duet singing, stage hosting and event emceeing for medium-sized crowds, free of cable restrictions
Spacious Reinforced Wedge Monitor Cabinet
Measuring 50.6cm (Width) × 33.4cm (Height) × 41.8cm (Depth), the K40 PRO features a larger reinforced wedge monitor cabinet with thick shockproof casing and wear-resistant metal mesh grille to fully protect internal high-power drivers during frequent transport to stages, wedding venues and outdoor festival grounds. The classic angled wedge shape doubles as floor monitor for performers and main playback speaker for audiences, with sturdy integrated handles for easy lifting and loading into transport vehicles.
Designed for semi-professional bands, event planners, street performers and large karaoke lovers, the K40 PRO 380W combo amplifier combines dual-woofer powerful full-range sound, dual DSP audio optimization, multi-channel professional inputs and ultra-long battery life with charge-while-playing convenience. It is the ultimate all-in-one portable stage audio solution for medium-sized live performances, outdoor festivals and commercial entertainment events.
