QED Speaker Cable (1.5m)

QED Speaker Cable 1.5m

This QED speaker cable connects an amplifier to a pair of speakers over a 1.5 metre run. Speaker cable is the final link in any hi-fi or home cinema system: every note the amplifier produces travels down this cable before it reaches the speakers, so the connection needs to be sound, secure and the right length for the room. QED is a British brand with a long history in audio cables, and this 1.5 metre length is sized for compact systems where the amplifier sits close to the speakers it drives.

Key features

• Speaker cable from QED, a specialist audio cable brand
• 1.5 metre length for compact amplifier-to-speaker runs
• Connects an amplifier or AV receiver to passive loudspeakers
• Sized for desktop, bookshelf and small-room systems
• Short run with no excess cable to coil or hide

The role of speaker cable in a system

An amplifier and a pair of passive speakers cannot make sound until they are joined, and the speaker cable is that join. It carries the amplified signal, at real electrical power, from the amplifier’s speaker terminals to the terminals on each speaker. A cable that is properly made and firmly connected keeps that path clean and consistent for both channels, so the left and right speakers receive the signal as the amplifier intended. It is also the part of a system that stays in place the longest, often outliving several changes of amplifier or speakers, which is why choosing a cable from an established specialist brand is the usual practice.

Why 1.5 metres suits compact setups

Cable length should follow the room, not the other way round. A 1.5 metre run fits the arrangements compact systems actually use: a desktop amplifier driving bookshelf speakers on the same desk, a small hi-fi on a shelf with speakers either side of it, or the front channels of a home cinema setup where the receiver sits in the unit between the speakers. In each case the cable reaches comfortably with a little slack for positioning the speakers, and there is no leftover coil to hide behind furniture. Excess speaker cable coiled on the floor adds nothing to a system, so a length matched to the setup is both tidier and more sensible.

Connecting amplifier to speakers

Speaker cable runs are installed in pairs, one run to each speaker, and the essential rule is polarity: the positive terminal of the amplifier channel connects to the positive terminal of its speaker, and the negative to the negative, on both sides. Systems where one speaker is wired in reverse still play, but the bass thins and the stereo image loses focus, so checking polarity at both ends is worth the minute it takes. Connections should be firm at every terminal, with no stray strands bridging the gap between terminals. Once connected, angle the speakers toward the listening position and let the system settle into the room.

A foundation part of a small system

Whether the system is a first hi-fi built around bookshelf speakers, a desktop setup for nearfield listening, or a compact home cinema front stage, the speaker cable is a foundation part: invisible in use, but responsible for the last stretch of every sound the system makes. This QED cable covers that duty at the length compact systems need, from a brand whose entire reputation rests on audio cabling. Matched with secure connections and correct polarity, it lets the amplifier and speakers perform the way they were designed to.
