bkwa1959 Posted February 7 Share Posted February 7 I have a pair of Klipschorns that have alk-crossover and I want to install the original Klipsch ak-4 crossovers, the crossovers have a +t and -t on one end of the crossover and on the other end has lfin- and lfin + W- w + m- m+ hfin - hfin + has anyone had experience connecting these to the terminals on the trap door. Trying to get my ak-4 Klipschorns back to original crossovers .Any help will be appreciated Quote Link to comment Share on other sites More sharing options...

I believe it has already been pointed out that there is a "T" next to these and they are the wires going to the Tweeter Binding Post for the crossover. To confirm this you should see that the (-) wire which should go to the (-) Tweeter Binding Post should be electrically connected the 100 ohm 25 watt resistor on the network circuit board. On the other side there are four sets of wires: "W + and -" which connects to the woofer Yes "M + and -" which I presume connects to a separate biding posts for the mid horn Yes + and - HFIN which I take to mean High Frequency In and would go to binding posts for the tweeter No.. These go to the HF IN Binding Post and are either directly connected to a second amplifier if Bi-Amping or are connected to the LF IN Binding Post via the external Jumper wire otherwise. Note: you can hook these wires to the LF IN Binding Post if you never intend to Bi-Amp and save the cost of one set of binding post. + and - LFIN which I take to mean Low Frequency IN and I have no idea if I should need a fourth binding post for that. This would be the connected to the LF IN Binding Post which is were you will connect the Amplifier wires to. So do I need four sets of binding posts and how do I hook this all up. Also since I won't be bi-wiring these, do I have to run jumper wires between three sets of binding post (in other words everything but the posts for the audio in) You need four binding post if you want the option to BI-Amp at some point in time otherwise you can get by with Three binding post by connecting the LF-IN and HF-IN to one set of binding post (For Amplifier Hookup) and thus eliminating the necessity for a jumper wire(if using a single amplifier) for the original BI-Amp option. miketn I borrowed this post about an AK-5, by @mikebse2a3 from a while back. It is good guidance but, try to find some pictures of the OEM AK-4 and study them. 1 Quote Link to comment Share on other sites More sharing options...
