1Introduction

The R7 loudspeakers have been designed to be

effective, easy to use, and above all to reproduce

music.

The R7 features a new three-way driver system

developed from our flagship loudspeaker the R9,

incorporating a quarter wave transmission line and

a single 7" side firing drive unit fitted with a 6 layer

voice coil in aluminium rather than copper, it needs

no additional crossover. This unique design

creates a natural bass extension, without

compromising any of the midrange and treble

which Rega is renowned for.

Siting of the R7’s.

The R7 loudspeakers use a 7” side firing bass

drive unit with a side firing port. Having a side drive

unit and port on the speaker would suggest facing

the two drive units outward, away from each other.

This can prevent mid range frequencies from

being directed at each other and causing potential

sound deficiencies that could occur if the two

speakers were in close proximity with each other.

However, there is really no written rule so on

installation you should experiment with different

positions to find the optimum placement that best

suits your needs.

The R7 is suitable for all room environments due

to it's ease of positioning and may be used with or

without grilles.

Bi-Wiring and Bi-Amping

The drive units in the R7 have been designed with

great care. The crossover needs no additional

filter networks to compensate for drive unit

problems. Unlike most manufacturers who boast

about the complexity of their crossovers, Rega are

proud of the simplicity of theirs. This simplicity

means that bi-wiring will offer no advantage, and

will often give worse results at an additional cost.

Bi-amping will improve the performance of both

mid/bass driver and tweeter units.

For normal use simply use either pair of +/-

terminals to drive the tweeter and bass/midrange.

For bi-amping, remove the bridging connectors,

and use the left HF +/- terminals to connect to the

high frequency tweeter, and the right LF +/-

terminals to connect to the low frequency

bass/midrange driver.

Plugs and Cables

We recommend using good quality speaker cable

such as our own, 'Quattro' or 'SC42', terminated

with mechanically sound 4mm plugs. Very

expensive leads claiming to use special materials

and technologies are not recommended. Cable

lengths to either speaker must be kept to a similar

length. Never join cables together to increase their

length.

Power handling figures are quoted as a guide.

Amplification between 30w and 500w can be used

safely depending on the quality of amplification.

Assembly

After unpacking the speakers from the box, fit the

spikes to the plinth. Please pay attention to the

warning in the spike pack. Ensure that the spikes

are secured tightly in the speaker plinth.

Please do not re-tighten the screws on the drive

units. They are fitted to a measured torque and

over tightening will strip the thread.

The grills are easily removed and applied, we

recommend their use to prevent damage and long

term build up of dust especially on the high

frequency unit.
