ISP Technologies BASS VECTOR PRO - Manual (Page 2)

INTRODUCTION
Tired of the limited performance of 4 x 10 bass cabinets? ISP Technologies has
taken a different approach to the modern bass guitar system. Combining the
low frequency extension that only an 18” driver can achieve with the natural,
extended (but not brittle) highs of dual 8” drivers, the Bass Vector cabinet
achieves a balance of depth, impact, and definition that makes 4 x 10’s sound
lifeless in comparison! At low frequencies, a single Bass Vector exceeds the
output of a typical 4 x 10 cabinet by 4 dB or more at 40Hz.
Available in active and passive versions, a single active cabinet delivers 600
watt RMS to its speakers. When an additional passive cabinet is connected, the
amplifier delivers a total of 1000 watt RMS to the two cabinets. Adding
additional active and passive cabinets can further increase the total system
power. There is a limit of one passive cabinet per active cabinet.
The ISP Beta Bass Preamplifier is the ideal ‘head’ for the system, or the active
cabinet can be used with other bass heads when driven from their line output,
and the passive cabinet can be driven from virtually any powered bass head.
The high performance 18” driver is complemented by an advanced cabinet
design featuring optimum volume and a large, deep tuned port. This helps to
minimize the non-linear behavior and reduced low frequency output that small
ports produce. The cabinet is tour grade, with Baltic birch plywood
construction, dadoed joints, extremely durable rubberized polyurethane finish,
metal handles and casters.
PRO VERSION
The ‘Pro’ version takes this concept to the ultimate by the use of a cutting-edge
technology, ultra-high excursion, 1100 watt rms 18” driver, and dedicating the
entire 1000 watt amplifier to driving a single cabinet. The output is increased
by 2 to 3 dB over the standard Bass Vector, and simply leaves standard 4 x 10’s
in the dust, typically exceeding their output at 40 Hz by 6 dB or more at high
volumes.
Want more output? The total system power can be further increased by adding
additional active cabinets. The line-array topology allows for stacking up to 4
cabinets, keeping the 8” drivers in a vertical line for the best horizontal
dispersion of the highs.
