Added 2 of these bad boys to my system, and by the way They Thump really well.


Introducing the Thump
TH-15A 2-Way Powered Loudspeaker

High-Performance Audio Without the High Price Tag.

Designed by the same team that produced the best-selling Mackie SRM450v2, the Mackie Thump TH-15A delivers deep low-end and real power in a lightweight design that is extremely portable. Class-D Fast Recovery™ amplification pushes 400-watts of power to the high-frequency compression driver and bass-pounding 15″ woofer. Plus, Mackie Active processing, including a precision crossover and driver time-alignment provides total optimization for maximum system efficiency.

Versatile by design, the TH-15A features a user-adjustable 3-band EQ for tone control and, since it can be pole-mounted or used as a wedge, the TH-15A represents the best value available for a complete stage solution.


The new Mackie Thump TH- 15A powered speaker cabinet proves that the race for lighter, cheaper and more powerful PA speakers is truly on. In the last couple of years there have been a few manufacturers who have managed to produce astonishing power-to-weight-ratio active speaker cabinets at really affordable prices. It was inevitable that a company like Mackie, who has had so much success already in the market place with products like the SRM-450, would join in at some point. The result is the Thump TH-15A, designed by the same team as the SRM-450, which offers 400 watts of Class-D fast-recovery amplification in a two-way polypropelene enclosure. The cabinet is extremely lightweight and portable, weighing in at just over 16 Kg or 36lb, and can be used either pole-mounted, stacked or as a wedge monitor. The carry points are moulded into the design, so there are no sharp edges or handles sticking out to damage upholstery or car interiors.

The 15″ woofer pushes out 300 Watts, while the 1″ compression driver deals with  100 Watts of high frequency. Mackie has included its own active processing, which not only provides driver time-alignment to ensure that both high and low frequencies arrive in sync, but also a precision two-way crossover and a compressor circuit to prevent overload and protect the speaker from damage. Each cabinet has a mic/line XLR input and ‘thru’ connection, as well as adjustable three-band contour EQ with a sweepable mid.


They didn’t name these speakers Thump for nothing. The emphasis is definitely in the low end, which will make them very attractive for DJ’s playing principally dance tracks. That’s not to say they don’t perform adequately for other types of music, and the parametric mid control comes in handy for fine tuning any boxiness that can occur with some music on this sort of speaker. For a house party, small gig or event, the Mackie Thump TH-15A will deliver the goods with ease. Plugging a microphone straight into the back works, but doesn’t really produce enough usable volume. With only one input, I can only think of a couple of occasions where this would be a useful feature. However, a pair of  Thumps offer an unprecedented solution – a big name PA speaker for very small money.

At this price, and with the features on offer – especially the portability, Class-D amps and the protection circuits – these active PA speakers are going to be massively popular. There’s also a compatible sub-woofer, the TH-18S, which, although not quite so reasonably priced, will give this system some serious low-end. It seems that Mackie may have just taken the field by a nose with the Thump TH-15A.
