    Fantastic woodwork on that baffle! Looks gorgeous.

    What are dimensions of the baffle? I know that the Eminence Alphas are the favourite driver due to high Qts (hence low mass corner), but will the relatively narrow baffle lead to an early baffle roll off?

    I was just at Axpona and heard the Trio 15 Horn1 with the Whammerdyne tube amp. It sounded fantastic. How does your implememtaion compare to the Trio 15TB as that model uses the full range driver? I would like to build something similar.

    Wonderful. This is the project I was looking for. How can you get the dimensions of the OB and the assembly diagram of the crossover?
