Car Stereos: Best sound for a convertible, part 2, rear speakers, range drivers


Question
Thanks for your excellent response to my first question Brian, much appreciated.  I have a follow-up question.  If I'm going to use a midrange driver in the rear as you suggest, then I have two options.  1) I can use the DLS UP6i 2-way system (midbass & tweeter) in the doors and simply add the DLS up 2.5 midrange in the rear, or 2) I can use the DLS UP36i 3-way system (midbass, midrange & tweeter) putting the drivers in the same locations.  In Option 1, the crossover divides the signal between midbass and tweeter, with the midrange overlapping both to an extent using the filter you described.  In option 2), the crossover divides the signal between midbass, midrange and tweeter (no overlap).  Which would be the best for my situation?

Answer
Hi Patrick,

If I'm understanding your question correctly, then I'd go with option 1, hands-down.  

I realize that imaging is less important to you than a clear high output level, but if you divide your frequency range between front and rear drivers, you'll be destroying your imaging entirely. The source of the sound will seem to shift all over the vehicle, in a way that's likely to be very distracting.  

I think you're much better off with a full-range output in the front, and just using the mid-range drivers in the rear for a filling effect.  I suspect that once you start listening to the system, you might decide to step down the rear speaker output until it just contributes to an illusion of more depth in the sound field.  You also mentioned in your first question that you might choose to drop out the rear speakers entirely when driving with the top up.  If the rear speakers are solely responsible for the mid-range output, then shutting them off won't be an option.

Hope this helps!

Brian
