RARE Mackie Analog SR1521z & SWA1501 - Set of 4 Active Cabinets

Turnkey, club-shaking PA rig ready to deploy – a matched pair of Mackie SR1521z active 2-way tops stacked on a pair of SWA1501 active 15" subs. This classic Analog Mackie SR/SW series combo delivers that legendary tight, punchy sound that dominated small-to-medium venues, DJ gigs, bands, and mobile setups back in the day. All four cabinets are fully active, no external power amps required!

• Built-in active circuitry provides precision crossover, accurate electronic time correction, phase alignment and equalization
• XLR I/O
• Linear response from 40Hz to 20kHz at high SPLs
• Full electronic and component protection circuitry
• Weight-balanced with side handles for easy carry and set up
• Top and bottom handle for easy repositioning
• Subs (SWA1501): 
• 500W RMS each, high-output 15" driver with 3" voice coil

Condition: Excellent – These were used for watching movies and listing to music at home. Grilles are available, drivers have no rattles or issues, amps run cool and clean. All controls and connectors tested and working flawlessly. No blown drivers or repaired components.

This is a complete stereo system: 2x tops for mids/highs, 2x subs for earth-moving low end. Ideal for DJs, live bands, mobile entertainers, or as a killer house/club install. Mackie discontinued these years ago, and matched sets in this condition are almost impossible to find.

Active analog electronic crossovers all the way. Precision filtering, phase alignment, time correction, and EQ are handled by the onboard analog circuitry – no DSP or digital processing. Seamless integration between tops/subs with the subs' built-in 120Hz high-pass outputs.

These are true old-school active designs: rock-solid, road-proven analog electronics that deliver that warm, punchy Mackie tone without any digital conversion artifacts.

Used market for clean SR/SW series pieces is scarce these days, making solid matched rigs like this even more valuable for that vintage analog vibe.
