    azzd, time alignment is hard to get it right down to a sample either way. I think you will find your IACC will increase with time alignment. For sure, a 5 way is a daunting task, but it should pay off. I agree with Rod's assessment of time aligning drivers: http://sound.whsites.net/ptd.htm

    I have to tell you it took me three tries to get it in the ballpark of understanding what was going on. My book in the sig has a much more detailed step by step than he article you read. However, I am happy to assist if you want to PM me, when you are ready. Really nice speakers, would be a shame not to have the drivers timing nicely integrated, especially since you already have the digital XO.

    That is a very nice collection of speakers in an impressive enclosure!

    Would you share your final crossover points and slopes of your setup?
    Why did you choose that tweeter over a JBL 2405 for example?

    Have you considered to put your cabinets on some speaker-stands?
    Raising them a little of the ground would prevent the 2235h from sounding boomy...

    why was the horn not mounted internally inside the cabinet did you not make the back
    baffle removable.

    those looks awesome, small for their space but very domineering. nice work.

    Thank you Dr.db. Sorry for the late reply. Have not got chance to check the forum recently. Got Mitchco's book for months, no time to do further measurement yet.

    The crossover points are: 193, 915, 3200, and 10000. Linear 2nd order Neville-Thiele. I am not experienced. Setting the points based on what Westlake does and the drivers measuring result.

    Since I couldn't find good price 2406 as Westlake uses. There was a good deal of the RAAL last year; and I found they may go higher frequency. So, tried the ribbon tweeters; and there is no special reason

    They are too heavy to put on stands for me right now. Thanks for the great idea! I may add the stands in the future.

    Bests,

    Thank you bldozier!

    Mounting on the front baffle is the only way I know This is not good if 2450 and 2425 drivers having problem. The back baffle is removable, but those many screws will be a big pain. I will make only the upper part removable want need to open it.
