REL Acoustics HT/1003 MKII – Performance Home Theatre

REL’s home theatre-focused HT/1003 MKII subwoofer is designed specifically to answer the challenge of an affordably priced, highly dynamic pure home theatre powered subwoofer in a handsome, compact package. The HT/1003 MKII combines a lightweight, modern 10” CarbonGlas™ (250 mm) driver, coupled to a powerful 300W Class D amplifier that runs cool, producing startling dynamics. Internally, REL designed specially adapted home theatre input filters that produce extremely flat bass down in the 20’s.

Purpose Built

The HT/1003 is designed to deliver the best bang (quite literally) for your buck when building a home theatre system, featuring compact cabinet dimensions and finished in an attractive, yet purposeful, line grained black aluminium-look and topped by a 12mm thick beautifully polished top that serves to damp vibrations on the critical top surface of the cabinet.

300w Digital Amplifier

To accomplish their goal of exceedingly high output in a such a compact footprint required a special amplifier. REL’s NextGen5 Class D amplifier frees up interior space whilst running cool, this results in more cabinet volume and that translates into ultra-deep bass despite its modest footprint. 300 watts means the driver is never starving for power ensuring high output, delivered effortlessly in a long running, reliable design. Within HT/1003’s input filter, REL designed specific inverse filtering to permit the CarbonGlas driver to extend much deeper than conventional designs.

Optional Wireless Connectivity

By adding the optional HT-Air module you can connect the HT/1003 MKII wirelessly. Unlike other wireless subs, the HT-Air uses unique zero compression technology. Using a state-of-the-art chipset, the HT-Air wireless transmitter offers flawless signal quality with zero compression, delivering a latency (lag) figure of just 16-20 milliseconds, it’s hugely superior to the more common Bluetooth method of wireless connection. Put simply, the bass keeps up and stays in time with the action.

Fantastic Product & Even Better Customer Service!
Fantastic Product & Even Better Customer Service! I don’t usually write reviews, but I had to take a moment to rave about this phone mount. Not only is the product itself sturdy, reliable, and exactly what I needed—it exceeded my expectations in terms of quality and functionality—but what really stood out was the incredible customer service. When I had a small issue, the team responded quickly, professionally, and went above and beyond to make sure everything was resolved. It’s rare to find a company that truly stands behind its product and values its customers like this one does. I would highly recommend this phone mount to anyone looking for a dependable solution—and if you ever do need support, you’ll be in great hands. Five stars all the way! 👏📱

Perfect Fit for My Tesla!
Size: Upgrade - For Model Y Juniper/Model Y/Model 3
I’ve tried a few phone mounts for my Tesla, but this one stands out. It attaches securely without any wobbling, and the magnet is strong enough to hold my phone even on bumpy roads. The sleek design blends in well with the car’s interior, making it look like it was built for it. Installation was super easy—took just a few seconds. The charging feature works great too, so I don’t have to fumble with cables while driving. If you’re looking for a reliable, stylish phone mount for your Tesla, this one is definitely worth it!
