Theebadone raises an excellent point about the difference in cabinet size between the Valencia and the Model 19....

I wonder how the 416 is gonna play crossed at 1200 with that 19 crossover, in that small of a cabinet.
I'm starting to wonder if I should leave well enough alone. Right now, my Valencias and AS-101's sound great--they just need to be EQ'd differently than my Model 19's which is really not a big deal--they sound VERY close to the 19's with the "right" EQ (I mainly have to add some "extra" high end around 14khz and above with the Valencias and 101's that the Model 19's don't need). I'm now wondering if I buy 902's and model 19 crossovers (crossovers which were designed with a larger cabinet in mind) for the Valencias and 101's am I going to lose out on my frequency response from 1200 hz down (as far down as they go) because of the reduced cabinet size compared to the cabinet that the model 19 crossovers were designed/EQ'd for? I certainly don't want a midrange "gap" around 1200 hz or anywhere in the lower range for that matter just because I'm using a Model 19 crossover in a considerably smaller cabinet than it was designed/EQ'd for. On the other hand, if I buy 902 drivers and use the stock Valencia and AS-101 crossover (800hz), will I be missing out on a lot of the high end without the high frequency EQ that the model 19 crossover provides (which Old Guy and West End referred to)? I'm starting to worry that if I buy 902's I'll be "screwing up" two great pairs of speakers (that are currently "stock" and now have a relatively flat response in their primary response range) no matter which stock crossover I use (stock model 19 crossover or stock Valencia/AS 101 crossover). Call me crazy but I don't really want to spend that kind of money to "screw up" my speakers! Any ideas out there--is it really a good idea to "upgrade" these speakers with 902's using either stock 19 crossovers or stock valencia/AS 101 crossovers? If I need to custom build crossovers or use active crossovers I think I'm going to keep everything the way it is now. Any advice is greatly appreciated.....
