Nice job! Glad they sound great. What is the Howards product you use? I might do my Model 19's and 14's this spring--they could use a little oil (or whatever that Howards stuff is--I think AB recommended it once in a thread here too). I was also wondering, are you using the Model 15 crossover in it's "stock" configuration with the 414's or did you customize it at all to compensate for switching the stock woofers with 414's. Or was no tweeking to the crossover necessary--did it just sound great as is with the 414's?
