    offense? not at all; and this is probably the simplest of the SDA xovers, with only one tweeter.

    I am not sure about the solens without a bypass; you might try and see if you like it.

    HTrookie,

    I hope I did not dig up a hornets nest. Your input is invaluable because 3.1's info can be hard to find. Congrats on the sale.

    Thanks for the help,

    Where is the crossover inside of the speaker. Is it near the binding post?

    If thet are like the other sda'a you will need to remove the passive radiator,and it should be mounted on the on the inside of the binding post cap,or therby,,careful when you remove the passve fluid filled radiator,so as not to spill any liquid. ;) :rolleyes: :D

    Looks to me like it's on the terminal cup. Never oepned a pair of 3.1TL's so couldn't say for sure, but the 1st photo in the 1st post that's what it looks like to me.

    Hello HTRookie:

    Your post is very informative. I have 3.1TL's with crossover issues, however my crossovers have a 2 ohm 5% 25W resistor you make no mention of.

    This is connected on the board connector just above R3 and just left of the 55UF cap. The schematic you posted does not show this! Do I have some odd 3.1 xover? I attached a pic below.


    Now I'm more confused than ever. :eek:

    That's odd. I wonder if someone added those resistors in an attempt to tame the SL3000's.

    That resistor was not on my crossover. The rest of the components are the same, so if you are having issues you might as well remove that resistor and see what happens.

    All's well that ends well. I tok out the resistors and it was much better. Then my neighbor came over and saw them. He owns 'em now. I got back my investment, and he can rebuild the crossovers. Life is good. Next time out I'm gonna find some real minty 1.2TL's with no issues and just cut directly to the chase! :p
