The SA-155T-PA Package delivers a complete four-speaker PA system for bands, DJs, and venues needing serious coverage without the complexity. This ready-to-run package combines four passive dual 15" speakers with a professional 4-channel power amplifier and all necessary cables.

Each speaker cabinet handles 1400 watts peak power and features dual 15" woofers paired with titanium compression horns for full-range sound projection. The included 4-channel amplifier delivers 4 x 500 watts RMS at 8 ohms or 4 x 850 watts RMS at 4 ohms, with bridge mode capability pushing 2 x 1600 watts RMS at 8 ohms for maximum flexibility.

The dual 15" configuration provides the low-end punch needed for live music and DJ sets while maintaining vocal clarity through the mid and high frequencies. These passive speakers offer 8-ohm impedance for efficient power handling and reliable performance across extended use.

This system handles mid-sized venues, outdoor events, and club installations where you need to cover 200-400 people with full-range sound. Perfect for bands running monitors and mains from one amplifier, mobile DJs working larger events, or permanent installations in churches and community centers.

The package includes four 25-foot Speakon cables for immediate setup. Connect your mixer to the amplifier inputs, run the Speakon cables to your speakers, and you're ready to perform. All components ship together for convenience.

Frequently Asked Questions

What size venue can this PA package handle?

This four-speaker system comfortably covers venues with 200-400 people, depending on the space and music style. The dual 15" speakers provide enough output for outdoor events, medium clubs, church sanctuaries, and school auditoriums. For smaller intimate venues under 150 people, you might only need two of the four speakers active.

Do the speakers come with all necessary cables?

Yes, the package includes four 25-foot Speakon speaker cables to connect the amplifier to all four speaker cabinets. You'll need to provide audio input cables from your mixer to the amplifier, but all speaker-to-amplifier connections are included and ready to use.

Can I run monitors and main speakers from this amplifier?

Absolutely. The 4-channel amplifier gives you flexibility to run two main speakers and two floor monitors, or use all four channels for main PA coverage. You can also bridge channels for higher power output if you want to run fewer speakers with more watts per cabinet.

Do I need a subwoofer with these dual 15" speakers?

The dual 15" woofers provide substantial low-end response for most live music and DJ applications. However, if you're playing bass-heavy electronic music or want that extra sub-bass impact for large crowds, adding a dedicated subwoofer will enhance the bottom end. These speakers work great as full-range mains on their own.

How do these compare to active powered speakers?

These passive speakers require the separate amplifier (included in this package) but offer more flexibility and potentially better longevity since the amp and speakers are separate components. Active speakers have built-in amplifiers for simpler setup, but if an amp fails, the whole speaker is down. This system lets you replace or upgrade components independently.
