A: YES, this is very important, when hanging either a single or a double ES1.0 enclosure, in a Left/Right configuation, the left hang should have the horn on the 'outside', port on the 'inside, similarly, the right hang should mirror this effect.
The reasons for this are that the enclosure and horn are designed to disperse the sound in a downward effect,(approx 10-15deg depending on frequency), and similarly to reduce reflections from the outside walls and perimiters.
All KV2 Audio loudspeaker units are designed with low loss, low compression horn assemblies and are low’q’.
Their wide dispersion aspects mean that physical side by side ‘arraying’ is not the correct method or way to utilize the loudspeakers in application, primarily due to the interaction effects which cause poor phase response, frequency response and in-accurate dispersion.
It is entirely feasible to utilize a combination of two ES1.0 enclosures, providing that they are located and placed as highlighted in the picture below.
Yes, it is possible to use any of the EX Subwoofers as an extension, or addition to other KV2 product ranges, however it is important to recognize and understand that the phase of all the EX subwoofers is ‘Opposite’ to the ES subwoofers, so to use in a correct manner and to achieve the desired effect of ‘addition’, a reverse phase XLR connector will be required.
* Please note: If you are using the EX2.5 MkII, then you will need to add a single passive ES2.6 to maintain full output and balance of the system.
