RELs are designed for speed and articulation, as well as bass response. The T/5i uses a lightweight alloy driver more bracing, and even faster input stages to keep up with the best speakers on the market
1) REL subs are designed to be fast and articulate above all. This allows them to keep up with modern loudspeakers and blend better with them. REL subs offer realistic bass extension… there’s no point in adding a boom box for bass in a good system. Real life bass is quick and dynamic, it takes your breath away. RELs offer deep but fast bass, textured and organic, just as it is on the recording.
2) RELs use a high-level input, also called a speaker-level input. This means that they connect to the speaker output terminals on your amp, and share the same signal and are subject to the same damping factor and timing as your loudspeakers. Don’t worry, they don’t add to the load on the amp–they just see the signal.
3) Many REL setups are scaleable and they offer a separate input and gain setting for LFE/.1, so it’s easy to share your music sub with your cinema system.
The result is a subwoofer or pair of subwoofers that seamlessly takes your loudspeaker bass performance down to extremely low frequencies, but keeps all of the speed, detail, and dynamics of the signal. When done right, it’s not just about bass performance–soundstaging improves, there’s more weight to all frequencies, and there’s a tremendous sense of the recording space.
