    Pioneer HPM100 vs HPM200

    Besides the wattage rating, what is the difference between Pioneer HPM100s and 200s. Are the drivers rated differently or is it just the crossovers that are different. Apologies if has already been covered, I performed a general search on HPMs and there were many, many posts. Thanks in advance.
