    Just returned from Richard's house -

    I was very impressed with the sonic differences with the modifications! :)

    I will give a more detailed review after a week or two of "burn-in". However, initially I am very pleased. I spun my reference vinyl (Miles Davis - Kind of Blue) and immediately noticed new highs and deeper lows. In particular, I am very happy to hear the cymbals much more clearly. Also, both piano and cymbal notes have longer trails. I have a set of Larry's rings that have yet to be installed.

    This is a must modification. Thanks Trey!

    Did you re-use the stock internal wiring between the terminal plate and crossovers? It looks brand new and so cleanly installed if it is in fact stock wire.

    Also, change out those old shotty jumpers.

    Gosh I want my new crossovers sooo bad!

    That is the stock wiring, the last generation of SDAs I believe used all white wiring which was completed extremely neat! :)

    Me and Richard talked about this - it is on the list! :)

    Gosh I want my new crossovers sooo bad!

    Soon! :-P

    Larry - let me know man! :)

    Richard - I am glad to hear you are enjoying them and cant wait to hear your thoughts as they burn in! :)

    The whole tweeter network - roughed in - caps not connected

    Test mount - top plate where all of the molex connections will go - this is just a test fit - don't like the stand offs on the corners, most likely will scrap that as they are not needed and it bends the bottom board - will look into alternate mounting... :)

    This is definitely a mod that looks cooler in person. It is such a large crossover...
