    I want to build this tower but I was wondering how hard it would be to build the crossover?

    Have you built crossovers before? I built the Proac 2.5 Clones and the xovers require soldering and placement on a board of some kind just like any other speakers' xover. Depending on your needs, there are other (better) designs out there. If I had it to do over again, I would have built these - http://www.ellisaudio.com/1801.htm

    Search the Madisound Board for past discussions on the Proac Clone. -

    Kevin, I appreciate the post VERY much. Can you give me a little more info on the 1801 and how it performs or why it is better? I'm very interested! Thanks!

    Also, how does it compare to the GR Reseacrh A/V-1 or 2?

    I think the 1801 requires you to have very good upstream electronics or it will reveal how poor they are. The speaker, from what I have read, is very precise, measures flat, and maybe even clinical in nature. This may not appeal to some. Read the reviews here:

    On the other hand, the Proac clone is a nice speaker, but I had issues with the upper end being very sssibilant. I had to pad down the tweeter with a resistor which may have moved the xover point and ruined the xover integrity. The original Proac 2.5 was designed to be used with tube equipment and I am using Solid State for amplification. I didn't know this before I built the Clone. The speaker images well, but I feel fatigued after longer listening sessions. It kind of sucks knowing that the xover is compromised to make it listenable(for me)after spending almost $600.00 in parts.

    I don't know how it compares to the av1's.

    I'm now looking for an open baffle speaker design which uses passive xovers.

    YMMV

    Kevin,

    I was looking at the PHOENIX open baffle, but I don't know how much it will cost to build such a speaker. I also don't know how hard it would be to build the kit in general.

    The Phoenix will cost a small fortune.. If you build it to
    spec then you need to buy the amps, active crossovers from
    Linkwitz and it all gets very pricey coupled with the fact
    that it uses some fairly pricey drivers also.

    You may want to look for posts from Stephen Dobbs(I hope I
    got that right?) he built his own Phoenix Clones and used
    DBX DriveRack Active Crossovers and different amps.
