Good point.

While out upgrade steps will be clear, concise and distinct.

he individul can of course decide on the degree of enhancement to his/her 4343 system

Be aware however that it will not be a 4344 (spec) and some juggling of the crossover will be necessary if you mix some of the drivers and not others.

Part 9 of the upgrade will also discuss use of modern drivers!
