This manual will give you a quick overview of how to set up your speakers in your room. For more in-depth in- formation about the technologies please refer to the R 907 technical description. The fi rst word of advice. After setting up your R 907s for the fi rst time, please allow yourself a couple of days to listen to them before you start fi ne-tuning the sound. This will serve two purposes. Firstly, you will get a sense of what these speakers sound like. Secondly, it will give time for the speakers to run in: the tonal quality of this design changes slightly after the fi rst couple days of playing music. Please remember the guidelines in this manual are only recommendations. There are no hard and fast rules about setting up a pair of speakers as unique as these. When you get down to fi ne-tuning their performance in your room don’t be afraid of experimenting: any speaker will sound different when moved a few inches. Feel free to change the speakers’ positions and move them around the room to deter- mine your best listening position and sound. Always rely on your own judgement to determine what sounds best. We do... Enjoy!7 PLACEMENT As a starting point, we suggest you initially position the R 907s 3 feet from the back wall and 4 feet from the side wall. Angling the speakers 10 degrees to the back wall will refl ect the generated sound off your back and side walls, which will give you the acoustic impression of a much larger room. Also remember that a dipole speaker emits virtually no sound from the side. You can take advantage of this trait to cancel refl ections from the side wall by varying the toe-in angle. 3 ft 4 ft 10˚8 LISTENING POSITION To fi nd the best listening position, place yourself at a 30 degree angle from each speaker. Doing so means that you will be seated at about the same distance away from the speakers as the actual gap between them. The benefi t of this is that the direct radiating sounds from each speaker will cross each other at a point behind you.

a) doesn’t allow you to get the speakers the required distance from the back and side walls or… b) has highly refl ective surfaces (ie. glass windows or bare plastered walls) or… c) still doesn’t sound quite right …we strongly recommend that you damp your room’s critical surfaces. This can be done by the simple expedient of adding curtains, furniture, bookshelves and so on. A damped surface is almost always preferable to a hard refl ective surface. 30˚ 30˚9 SPIKES After the initial placement of the speakers it’s now time to screw in the spikes. Be- cause of the weight of the R 907, we recommend that you gently lay it on one side and screw in all four spikes together. Before you do this, however, be sure to place a couple of thick towels or similar underneath the side of the speaker. This will pre- vent accidental scratching to the surface of the R 907 and, equally importantly, will avoid you putting a rather large dent in your fl oor. After screwing in the spikes, we recommend you fi t them with the hard rubber feet and the indented metal washers we’ve supplied. These will spare the fl oor from damage and allow you to gently bring the speaker to its vertical position. Once upright simply adjust the spikes to give optimal support. Floor surfaces vary considerably so we have given you 3 different choices when it comes to spiking options. You can keep the hard rubber feet on the spikes, rest the spikes on the four indented metal washers, or place the spikes directly onto the fl oor. Always choose the option that gives the most stability for your speakers in your domestic environment. Using the spikes without the hard rubber feet or indented metal washers will give the very best support and sound quality. If you want to spare your fl oor surface from being punctured however, the rubber feet or indented metal washers are a good compromise. Sonically, there’s really very little difference between them - use whichever one suits your fl oor surface better. A warning: be careful when using the spikes with the indented metal washers - you don’t want to get your fi nger trapped between the two! Whichever spiking option you choose, avoid “walking” the speakers if you need to move them to a different position… especially on hard wood fl oors!

CONNECTING SINGLE-WIRING For single-wire connections, the terminal jumpers should be attached as shown in the illustration. BI-WIRING If you’d like to use a bi-wiring arrangement, make sure you remove all the terminal jumpers before you connect up your loudspeaker cables. BI-AMPING In a bi-amped system, make sure you remove the terminal jumpers before con- necting up your cables. The top pair of terminals drive the tweeter while the pair underneath drive the bass and midrange units. If you choose this option, we recommend you use identical amplifi ers for both ter- minals.

FRONT AND BACK FABRIC COVERS

The front fabric covers have been designed to have minimal infl uence on the sound quality. However, for critical listening we would advocate that you remove them. The rear fabric covers have no infl uence on the sound quality. It’s entirely up to you and your aesthetic preference whether you have them on or not. When removing and putting on the front and back cov- ers, however, make sure you do so gently, in order to pre- vent scratching or marking. We recommend placing your hands level with the two top hooks on the front cover when lifting it, for optimal balance. We recommend placing your hands level with the two top hooks on the front cover when lifting it, for optimal balance. Please note that the front fabric cover, like the speaker itself, isn’t of conventional design. When putting the cover on, make sure all four metal hooks on its frame are resting securely on all four screws. If not placed correctly, it could fall off and per- haps even be damaged. If you choose to remove the front cover for longer periods of time, the four screws onto which you mount the cover can be unscrewed, for a more attractive aesthetic appearance.

It is also possible to use a slightly damp cloth for more stubborn marks. Under no circumstances should you use any kind of cleaning agent on, or in close proximity to, these speakers.
