THE CABINET RANGE
Using the finest materials, construction techniques and specially custom designed loudspeakers, we have
created a range of extraordinary bass cabinets which perfectly complement the power and performance of
the Dynamic Bass System.
The loudspeakers required highly specialised research, to enable them to handle the high continuous power
levels and awesome power peaks that the Dynamic Bass System is capable of producing.
These custom speakers all feature specially reinforced cone systems, high temperature voice coils and
massive magnet assemblies, all housed in ultra rugged cast chassis.
Connections to the cabinets are via heavy-duty locking sockets to ensure a safe, no loss high powered
termination.
Each cabinet is ported and carefully tuned to its matching speakers and integrates perfectly with other
models in the range to cover the entire spectrum of bass sounds.
Model 7410 4x10 with Horn (800 watts RMS -4 Ohms).
This cabinet has an unusually deep bass response for it’s type. Superb transient attack is provided by the
high frequency horn which features a 6 position attenuator control, from the horn fully off at one extreme to
the horn fully on at the other extreme.
The 7410's tight and punchy performance totally suits upfront modern styles of bass playing.
Dimensions - Height 698mm x Width 698 mm x Depth 380mm.
Model 7412 4x12 (800 watts RMS -4 Ohms).
Recognising the enormous potential that the 4x12 cabinet has to offer for bass, considerable engineering
time was devoted to the specially designed speakers and cabinet of the 7412.
Combining many of the best characteristics of the 2x15 and 4x10 cabinets together, the 7412 has plenty of
bottom end with rapid transient attack. This is the ideal cabinet for playing situations requiring a single
speaker cabinet with maximum tonal response.
Dimensions - Height 1000mm x Width 698mm x Depth 489mm.
Model 7215 2x15 (600 watts RMS -4 Ohms).
The model 7215 features drive units designed to achieve superb, high sensitivity bass response.
In addition to forming the foundation of a serious bass system when combined with either the 7410 or
7412, this unit’s complementary balanced high end provides enough presence and attack to allow it to be
used on its own.
Dimensions - Height 1000mm x Width 698mm x Depth 489mm.
Note: (The RMS power handling figures are for comparison only when used with non Dynamic Bass
System amplifiers. The peak capacity of these cabinets is individually matched to the performance of the
Dynamic Bass System amplifier).
23. D.I. Level Selection Switch
Selects 0dB or -20dB D.I. output levels for
maximum interfacing flexibility.
24. Balanced D.I. Output
For direct connection to recording or PA mixing
desks and switchable pre or post EQ (16).
The D.I. output is fully transformer isolated to
guarantee against problems with earth loops and
hence an earth lift switch is not required.
25. Tuner Output Jack
Instrument level buffered output for direct
connection to an electronic tuner.
26. Effects Send Jack
Jack socket to connect to the input of an external
effects processor.
27. Effects Return Jack
Jack socket to accept the output from an external
effects processor. Note: (The output level of the
effects loop is nominally centred around + 4 dB
which makes it compatible with most rack effects
processors).
28. Line Level Control
Rotary control providing level control of the line
out from zero to +4dB.
29. Line Output Jack
Jack socket ideal for connection to home
recording equipment.
