Hello. I can buy a MTX Jackhammer subwoofer for $5000 us. For the same price I can buy 50 MTX 12 inch Thunder 4500 single voice coil woofers. You might have seen the MTV series "Pimp My Ride". It is used in a full size van. See it? Assuming you are using the same amplifier, lets say a Rockford Fosgate T15kw (15000 watts RMS) at $20,000. Which system will produce more sound? SPL. Bass?
