Marcus,
The larger drivers in the FRS 15s and taller cabinet compared to Walsh 2 should provide more "meat on the bones" and have more impact in the low end in a larger area like yours and bass extension beyond the Walsh 2s down into the 30hz range according to the ohm site specs.
The taller cabinets might make a difference in the height your ears must listen from for best results.
With a well matched amp, the Walsh drivers tend to sound most balanced and detailed when you listen from a vertical position in front of or somewhat above the can as a result of the shape and orientation of the Walsh driver inside .
The tonal balance can change and sound less bright and detailed if listening from a lower position than the drivers, I have found.
FRS series are less common than Walsh series I believe in that they were produced during the period when OHM was shifting away from the audio store distributor business model they used to have going into the 90's and to their current buy direct model.
I think I read somewhere the shift from pyramidal WAlsh series cabinets to more recent more rectangular cabinets was to help keep production costs in line.
PErsonally, I like the look of the older pyramid shaped cabinets but the newer cabinets appear to have a smaller footprint which may be of benefit to some.
