Tired of the limited performance of 4x10 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 speaker cab achieves a balance of depth, impact, and definition that makes 4x10's sound lifeless by comparison. At low frequencies, a single Bass Vector exceeds the output of a typical 4x10 cabinet by 4dB or more at 40 Hz. A single powered cabinet delivers 600W RMS to it's speakers. When an additional passive cabinet is connected, the amplifier delivers a total of 1000 watt RMS to the two cabinets. The total system power can be further increased by adding additional active and passive cabinets with a limit of 1 passive cab per active cab. 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 speaker 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 ISP Bass Vector is tour grade, with Baltic Birch plywood construction, dadoed joints, extremely durable rubberized polyurethane finish, metal handles, and casters.
