looking for a speaker posts tighting "wrench"?

There are a plethora of binding post styles out there.
Some manufacturers have their own
design of tightening tool, or design their posts to be
finger-tightened only. Many 5-ways have a hex type
tightener/nut. ie: I have always installed Vampire 5-
ways(BP-HEX),
on my amps and speakers, which take a 7/16" wrench. An
ordinary open-end wrench will provide more than enough
purchase, to obtain a gas tight connection, with any decent
hex 5-way. It's easy to over-torque a speaker post and spin
it(in it's mount), so- proceed with caution.

I like the AudioQuest Postman. While there may be some non-standard posts that it will not handle, this has proved to be ideal for almost all the standard ones. Also, its design allows it to fit closely-spaced posts where open-end wrenches cannot.

I second the Audioquest. I've had mine for years and it
wells very well.

My speakers have Cardas binding posts, which are recessed into a cutout in the (very thick) rear panel, and which have hex tighteners. An ordinary automotive ratchet/socket/extender combo did the trick for me. I was of course very careful not to overtighten, as Rodman sagely advised.

I like the AQ Postman due to the fact that it is insulated, therefore, reducing the possibility of shorting the two terminals.
