6. d recommendation for ideal stereo imaging is to ensure the tweeters left and right are installed in the same positions Also they are approximately at equal distance to the driver vice versa for the passenger The various positions advised should be verified and comparatives made for ideal positioning The tweeter should always be positioned ahead of the normal listening position The main prefe rences are the outer positions of the dash board fig A 1 close to the windshield fig A 2 Normally easy for installation The location close to the door mirror fig A 3 is also regarded as a good position and normally only requires a small amount of install work Lastly a position high in the doors fig A 4 is also acceptable even if it is not considered the best for optimised staging It is imperative to verify before any installation is attempted that enough space is available especially for flush mount applications Also that there will be no interference with security devices air bags door latches etc Woofer midrange K2 Power woofer midranges posi tioned ideally high in the doors fig B 1 produce optimal midrange frequencies thus integrating better into the rest ofthe system The 100 KP Slim thanks to its reduced depth feature allows easy installation into the outer positions of the dashboard fig B 2 If the woofer mids are positioned low in the doors fig B 3 the loss of midrange can be com
