This model was the first GROVER NOTTING® Principal Audio Monitor to be developed, therefore the benchmark for the entire range, with regard to common voicing and imaging characteristics.  The Code 4 is the quintessential multi-purpose monitor, designed for use in near to mid field listening environments. At an enclosure capacity of 16.6 litres, it is small relative to its performance capability. It delivers 105dB at 1 metre with a frequency bandwidth of 38Hz to 32kHz. Like the Code 1.5 it is remarkably linear through the Audio Information Band©, with Low Frequency reproduction tight and musical, thanks to the control and management capability of the Bandwidth Extension Module.  The Code 4 will be popular in all audio production disciplines. The Code 4 is designed for free-standing, but can be soffit mounted in some environments.

A Note on Loudspeaker Specifications -

It is a fact that while technical specifications are definitive; performance specifications are not. A speaker will perform differently subject to the constraints of its acoustic environment. When producing performance specifications, we believe they must represent the ‘real world’. We also suggest they be used as a guide only to the potential of a specific system. Therefore our performance specifications are produced, as a result of ‘real world’ testing, conservatively and with the goal of publishing useful data as opposed to marketing hyperbole.
