Frequently Asked Questions - R 907 JAMO

How to position the Jamo R 907 speakers for optimal sound?

Place the speakers 90 cm from the rear wall and 1.20 m from the side walls. Tilt them 10 degrees relative to the rear wall. The ideal listening position is at 30 degrees from each speaker, at a distance equal to the distance between the two speakers.

How to install the decoupling spikes?

Lay the speaker on its side (protected by towels) to screw in the four spikes. You can use the supplied rubber caps or metal nuts to protect the floor. Adjust the spikes for perfect stability.

What type of wiring is possible with the Jamo R 907?

You can use single wiring (jumpers in place), bi-wiring (jumpers removed), or bi-amplification (jumpers removed, two identical amplifiers recommended).

Should I remove the fabric grilles for better sound quality?

The front grilles have minimal impact, but it is recommended to remove them for critical listening. The rear grilles have no impact on sound, you can leave them as you prefer.

How to clean the Jamo R 907 speakers?

Use a soft dry cloth for dusting. For stubborn marks, a slightly damp cloth is acceptable. Never use detergents or harsh products.

What is the recommended break-in period?

Listen to the speakers for 2 to 3 days before making fine adjustments. This allows the drivers to break in and you to become familiar with their sound.

What if my listening room has very reflective surfaces?

Add acoustic panels, curtains, furniture, or a bookshelf to dampen reflections. A damped room improves listening comfort.

How to wire the Jamo R 907 for bi-amplification?

Remove the jumpers from the terminal. Connect the two top terminals to an amplifier for the tweeters, and the two bottom terminals to a second amplifier for the woofers and midrange. Preferably use identical amplifiers.

What is the coverage of the Jamo R 907 warranty?

The manufacturer warranty is 7 years from the invoice date. It covers hidden defects, but not damage due to misuse, unauthorized modification, etc. Keep the original invoice.

Can I move the speakers with the spikes installed?

Avoid moving them by tilting if they have spikes, especially on parquet. Always move them by lifting without sliding the spikes.

INTRODUCTION

Welcome to the exclusive circle of Jamo R 907 owners! This manual will give you a quick overview of how to set up your speakers in your room. For more in-depth information about the technologies please refer to the R 907 technical description.

The first word of advice. After setting up your R 907s for the first 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 first 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 determine your best listening position and sound.

Always rely on your own judgement to determine what sounds best. We do...

Enjoy!

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 reflect 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 reflections from the side wall by varying the toe-in angle.

3 ft 4 ft 10°

LISTENING POSITION

To find 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 benefit of this is that the direct radiating sounds from each speaker will cross each other at a point behind you.

IF YOUR ROOM...

a) doesn't allow you to get the speakers the required distance from the back and side walls or...

b) has highly reflective 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 reflective surface.

SPIKES

After the initial placement of the speakers it's now time to screw in the spikes. Because 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 prevent accidental scratching to the surface of the R 907 and, equally importantly, will avoid you putting a rather large dent in your floor.

After screwing in the spikes, we recommend you fit them with the hard rubber feet and the indented metal washers we've supplied. These will spare the floor 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 floor. 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 floor 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 floor surface better.

A warning: be careful when using the spikes with the indented metal washers - you don't want to get your finger 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 floors!

CONNECTING

SINGLE-WIRING

For single-wire connections, the terminal jumpers should be attached as shown in the illustration.

AMPLIFIER

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.

AMPLIFIER

BI-AMPING

In a bi-amped system, make sure you remove the terminal jumpers before connecting 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 amplifiers for both terminals.

AMPLIFIER 1 AMPLIFIER 2

FRONT AND BACK FABRIC COVERS

The front fabric covers have been designed to have minimal influence on the sound quality. However, for critical listening we would advocate that you remove them.

The rear fabric covers have no influence on the sound quality. It's entirely up to you and your aesthetic preference whether you have them on or not.

Warning symbol with exclamation mark and magnified view of a device handle

When removing and putting on the front and back covers, however, make sure you do so gently, in order to prevent 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 perhaps 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's also worth noting that the rear fabric cover is mainly held in place by magnets. When mounting it make sure that you gently push the two fabric cover holders into the corresponding brace holes.

CLEANING

Please use a dust-free cloth to clean the R 907. 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.
