High-Performance 12" Active PA Speaker With 1000W Class-D Power & Premium Sound – Mackie SRM450

The Mackie SRM450 is a high-performance, active 12" powered loudspeaker delivering 1000W of Class-D power in a compact, road-ready package—ideal for live bands, DJs, events, installations, schools, churches, rehearsals, or portable PA needs.

The rugged ABS enclosure with steel grille withstands touring abuse, while dual-angle pole mount, M10 fly points, and ergonomic handles offer versatile deployment—pole-mounted, flown, monitor wedge, or ground-stacked. Flexible combo XLR/TRS inputs and thru outputs make it easy to connect mics, instruments, or daisy-chain multiple units—perfect for professional sound reinforcement where reliability, punch, and clarity are essential.

Snark SN1X Clip On Guitar Tuner - Blue

Ordered guitar strings which arrived in two days, inside package was an offer for a guitar tuner which also arrived in two days. Excellent customer service.

Terence Hamilton
Audio Direct

At the offer price this was very good value for money. I have generally found Snark tuners to be very good although with the low tunings I use I often find they can take a little time to give an accurate reading moving from string to string. Otherwise, Great!

The Snark SN1X clip on guitar tuner is a very handy and accurate tuner, very easy to use and at a great prices too! 👍🌟🍺😸

Jason Davey
Snark SN1X Clip On Guitar Tuner - Blue

This is my second Snark Tuner, there are various versions, this one is for use at home the other is RF shielded and has rubber protection incase dropped. Both work excellent and are the best clip-on tuners I have used. The service given by Audio Direct was first class, Dave even telephoned me to discuss a query I had not something many online traders would do so overall 10/10

NUX Loop Core Stereo Looper Pedal

It sounds like it's supposed to sound, easy to shape the tone on each of my electric guitars. Yes, each of the amplugs is a one (or two) trick pony, but they do what they're supposed to well, and they each sound like the amp they emulate.
