The Stage, Premium and Professional Series cabinets are all the same. Since a woofer and cabinet should be matched, this is not always possible. In fact, it is rare that you can swap woofers in cabinets and stil retain an optimal match. However, there is a certain about of goal setting evident in the designs of each of the woofers used in these cabinets - Many manufacturers produce 15" woofers designed to work well in cabinets from 2.5ft³ to 5.0ft³ tuned to 40Hz.

Crossovers are slightly different, but quite easy to configure. You'll find a chart that shows the components required for each model in the plans.

As for your amps, your 50 watt McIntosh amp will work well with any of them. For that matter, so will your ASL 8 watt amp. I have used each of these with the 2.5 watt Bottlehead Paramour and the 9 watt Stoetkit Ultralinear amp and both sounded great.
