The RSG-15 portable PA speaker delivers complete sound reinforcement for performers, DJs, and event hosts who need professional audio without the complexity of traditional PA setups. This rechargeable 15-inch system includes everything you need in one wheeled package: two wireless VHF microphones, Bluetooth connectivity, and a built-in mixer.

Powered by a 150-watt RMS amplifier driving a 15-inch woofer with 75 oz magnet, the RSG-15 produces full-range sound from 45Hz to 18kHz with 96dB sensitivity. The Class A/B amplifier and 4-ohm impedance design ensure clean, powerful output for live vocals and music playback. A built-in 12V, 7.5Ah rechargeable battery provides 4+ hours of runtime, eliminating the need for AC power at outdoor events.

The RSG-15 handles venues up to 150 people indoors or 100 people outdoors, making it ideal for karaoke nights, small concerts, DJ gigs, school assemblies, and tailgate parties. The five-band EQ and multiple input options accommodate various audio sources simultaneously.

Connect instruments to the dual XLR/1/4" mic inputs, stream audio via Bluetooth, or play MP3s from USB drives or SD cards. The included wireless remote controls playback functions from across the room. Two wireless VHF microphones are included for immediate use.

All RSG-15 speakers ship free within the continental US and include Seismic Audio's one-year warranty. The injection-molded cabinet features integrated wheels and a retractable handle for easy transport between gigs.

Frequently Asked Questions

How many people can the RSG-15 reach effectively?

The RSG-15 covers venues up to 150 people indoors or 100 people outdoors. The 150-watt RMS output and 96dB sensitivity provide sufficient volume for karaoke nights, small concerts, DJ sets, and school presentations. For larger crowds, consider pairing two units or upgrading to a higher-wattage model.

What cables do I need to connect instruments and audio sources?

The RSG-15 accepts XLR and 1/4" cables for microphones and instruments through its dual combo inputs. For line-level sources, use standard RCA cables to connect to the line input. The included wireless microphones work immediately without additional cables, and Bluetooth devices connect wirelessly for music playback.

How long does the battery last during events?

The built-in 12V, 7.5Ah rechargeable battery provides 4+ hours of continuous use. Battery life varies based on volume levels and input usage. The speaker can also run on AC power while simultaneously charging the battery, making it suitable for longer events with power access.

Can I use this for outdoor events without power outlets?

Yes, the RSG-15 is designed for outdoor use with its rechargeable battery system and rugged polypropylene cabinet. The integrated wheels and retractable handle make transport easy across grass, pavement, or gravel. Weather resistance is suitable for covered outdoor areas, though direct rain exposure should be avoided.

Do the wireless microphones work reliably for live performance?

The included VHF wireless microphones provide dependable performance for vocals and speaking within typical venue ranges. VHF technology offers good interference resistance in most environments. For mission-critical applications or larger venues, consider upgrading to UHF wireless systems for extended range and frequency coordination capabilities.
