I would still do the battery test.
I would still do the battery test.
4406, 4412A, L100, L100t3 (3 pair), L1, L7, 4645C, 4660A, 4695B, SR4735 and various DIY JBL Pro loaded systems.
This seems to help. I took 'em off the tiny plant stands and per Giskard put the right one into the tv hole. My wife agrees this helps with the "decorating nightmare" as she so bluntly puts it. John, When I got these the setting were all +++, so I backed them all down to zero. Now will turn them all off and bring them up one at a time, to see if this help more. BTW, what settings are yours at and do you rent out that RTA?
Thx fellas...

Is it possible that what you are hearing is just a different frequency balance between the little and big guys?
If the 4312s fall off at the mids and highs compared to the big boys, especially if you have them exadurated, you end up turning up the volume further enhancing the bass and this could be perceived as enhanced bass response.
A sine wave generator and accurate sound level meter with linear weighting could tell if this were the case.
P.S. Send those 4350's over here and I'll check the bass for you compared to my L112's.
OH, and the woofs are refoams only

Hey Todd, The 50's are parked (literally) in the garage. I'm thinkin' about bringing them up to Sturgis at the bar. Just need to weigh the idiot-drunk factor

You're gonna like them better when they are bi-amped. There will be alot more control over the LF at least.
My 4315's are labeled +/- an extra line past 3 each direction. So I have UHF at - 3.5, HF at -2 and MF at 0. I'd suggest as you mentioned, turning them all down, then start with the LF at the volume you want. After that, bring each level control up to where it sounds balanced.

If we know the solid green is positive AND
green with black stripe is negative per JBL spec
AND the transducer clearly has a red and black terminal AND the wires are properly connected, what is a battery test going to tell me?
"It only costs 80% extra to go first class"
a barroom that allows smoking will destroy those 4350's faster than the drunks.smoke will get into everything.why waste a pair of those on a place where no one is listening anyway?
Jim, "thinkin' about it" are the key words. You're absolutely correct. However, this isn't your normal dark, dingy, smokey hole in the wall bar. We're talkin' 40 foot ceilings and open doors, etc. See the picture at www.oneeyedjackssaloon.com
either way, I'd have to crane them up to the ceiling and that would be a hugh effort. I could just build a new house to accomodate them however...

A battery allows you to see the cone movement and judge the polarity. If a woofer is designed to move outward when given a positive charge applied to the + terminal, you can apply that with a battery. Example: take a 1.5v battery, connect wires from the + battery terminal to the + of the speaker and do the same for the -, If you do that to both speakers and you find that one of them moves the opposite direction, you know that they are wired out of phase and that will cause cancellation, especially in the LF region, amongst other things.Originally Posted by invstbiker
BTW, this is a momentary test, do not leave the battery hooked up, just touch it for a second. And please use a 1.5v, it's scary to use a 9v IMO
Thx Steve, I'll give it a try the next time I have use of the crane
Why would the woofs be internally wired incorrectly from the factory?
"It only costs 80% extra to go first class"
I don't think that would be the case. If they have ever been removed for any reason, like a refoam, well, there is a chance, it happens to the best of us.
Well, Paul had them refoamed once to the best of my knowledge, so I do suppose anything is possible. Thx for the info!!

You are very welcome Sir, you'll get it figured out and be lovin' them soon. i went through changes setting up my tri-amped system, but once I dialed it in, WOW! .
