Jamo A 7 6·7

The inner and outer qualities

Cabinets

All four models are made of solid, resonance-dead MDF board and

come in several nishes. Except for the SUB 650, which features a

closed cabinet design, the other subs feature an integrated slotted

port cabinet. This allows for deeper tuning, superior power handling

and distinct sonic delity. Last but not least, the integrated port design

ensures great rigidity and stability in the cabinet design.

Ampliers

All four Jamo ampliers feature highly ecient BASH® amplier tech-

nology, which combines the musical quality of class A/B ampliers

with the eciency of class D ampliers. BASH® technology translates

into more ecient, yet more powerful amplication without the heat

associated with conventional ampliers. All four subwoofers feature a

convenient on/auto/o switch and built-in limiter, which means that

sound reproduction will always be clean and as well dened as in-

tended.

Drivers

At the heart of these powerful subwoofers are new, long-throw super

drivers, capable of moving large amounts of air with incredible speed

and precise control. The 8in and 10in drivers feature Ø 38mm/1.5in

four-layer voice coil and the 12in driver from the SUB 650 is equipped

with a Ø 50mm/2in, four-layer voice coil. The heavy magnet systems

feature a vented pole piece in order to avoid over/under pressure

behind the dust cap (mechanical damping) when the cone is moving.

These units are an important part of the reason why the four subs all

oer top specications and peak performance.

Test tones

To get the full benet of your new subwoofer you have to adjust the

phase and optimise the sound in relation to the room in which you

place your speakers. To make this process easy we have placed two

dierent modulated tones in the download section of www.jamo.com.

Placement tone

This is a modulated tone that sweeps up and down in the lower

frequencies. This will help you nd peaks and dips in your room. The

perfect spot for your subwoofer is where you hear the least peaks and

dips – or put another way, the attest response.

Phase adjustment tone

This test tone will help you phase your sub correctly and hence create

the perfect integration between the subwoofer and your frontspeak-

ers. This adjustment is extremely important if you want harmonious,

well-balanced sound from your speakers.
