I am going to be ordering my 2pi kit tonight or this weekend. I was wondering do the kits come with some kind of a binding posts? I was going to order some from parts express if not. I just want to make sure I have everything I need =)
Thanks in advance.
Phil

One of the reasons my 4Pis sound better than your 4Pis Very Happy

Gold-plated tellurium copper, no nasty tin or brass in the post although the thumb nut and washer are tin and brass. One of the few tweaky things, along with vibration control I believe in 'cause I can hear the difference.

Edison Price Music Posts are unobtanium and Cardas cost twice as much.

Now this guy in Hong Kong http://stores.ebay.com/Vintage-Audio-Lab has high quality speaker terminals and RCAs but the former are only long enough for amps. He also has a killer, really killer stepped attenuator for $25 which replaced my noisy Goldpoint and then mistracking PEC Pot in my passive. SMDs shouldn't sound that good and they don't. You don't hear'm! The volume goes up and down and you don't know why! It's amazing!

You know, I spend time on the Forums reading about how good or bad this or that is, then I play, as I did today a Chesky re-issue of a Layton/Mohr RCA recording of Scheherazade and just feel like "it" couldn't get any better. HW-19, AT-1005, Soundsmith re-tipped Aurum Beta S, Caravaggio phono, George Andersons SE Pentode circuit and finally, 4 Pis, all connected with "White Lightning" cords.

I installed some big solid copper posts Percy Audio used to sell- before copper became a precious metal! Between them and the 12-ga inductors for the woofers, the speakers are getting valuable... haha Well, at least for my continued enjoyment!

I got my kit today and have a question. Are you supposed to hot glue the crossover parts to the cabinet?

I like to mount mine with screws. Make a gasket and put it underneath:

OK I see how that answers my question but I am still lost lol. The 2pi crossover is simply a big black cap and a rolled up copper thing (I know technical terms =P) that are just hanging attached to the pertinent speaker wire. Am I supposed to glue these to a board and then do as you said? Also by the length of the speaker wire I am assuming you mount the binding posts in the center of the speaker box not at the bottom. Correct?

On the smaller speakers, I usually leave the wires hanging. The coil and cap will rest on the insulation on the bottom, so they won't buzz. On the towers, I wire tie them to the braces.

Or, in the 1960's style, solder the caps and coils to the terminals (on the inside of the box Surprised

) I repaired some KLHs for a friend not long ago and, although it was done for reasons of economy, it held the components darned well.

I just drilled the terminal cup holes for some 35" tall speakers today and decided 12" above the floor was perfect. High enough to be reachable by an old fat-man bending and low enough not to influence the speaker to lean from wire tension/weight.
