Efficiency balancing

[invstbiker]

This probably looks strange to you guys, but I'm wondering if there is an easy way to balance the efficiency so both speakers are putting out the same volume without going to multiple amps? Any ideas are appreciated!

Dunno...

But, you should also determine if each element in a like-frequency range is of the same phase.

(ps - I think that beautiful JBL blue looks great! Sure don't see any touch-up needed!! :thmbsup:)

The SDB series have volume controls

[Ian Mackenzie]

Try stacking two L100's atop close together in parrellel..in theory that would work if your amp does not mind .

The 4312's and 4333A's are currently connected in parallel (one set per channel)

The 4312's are louder than the 4333A's

Is it a simple matter of placing a potentiometer in line on the 4312's to get equal volume out of each speaker? (tone down the 4312's) I'm looking for a radio shack type of solution.

PS BO, The right 4333A (not shown) is the speaker that the bottom trim piece literally fell off. I re-glued it, however there is a small (tiny) area needing blue touchup paint.

Thx for any help here...

Is it a simple matter of placing a potentiometer in line on the 4312's to get equal volume out of each speaker? (tone down the 4312's) I'm looking for a radio shack type of solution....Yes. Purchase an L-Pad speaker volume control for each 4312, 8 Ohms. Connect per diagram provided therewith.

Once you do that, and get everything running and balanced correctly, hopefully you'll recognize what a bad idea this was, sonically speaking.

When it comes to loudspeakers, multiple systems playing the same program material in the same listening space is problematic. There's little harm in finding that out for yourself, of course....

Assuming your power amp is happy with the load you've already put on
it, you could try:

high wattage L-pad (e.g. partsexpress.com) which will keep your amp seeing
more or less the same load as you change the volume...

putting a power resistor (or high watt potentiometer) in series will
also drop the level... and drop your damping factor (may get sloppier bass...
or may not notice this at all). The higher value you choose, the more important
it is to make sure it doesn't get hot/smoke.

or a tapped transformer, but nice ones are more $$$.

I'm laughing ZILCH b/c yes it's probably a bad idea (at least my wife thinks so)

"Honey you've created a decorating nitemare" :blink:

But the ever experimenting person that I am will give it a try, and so we'll see what happens. Thx to all!

[grumpy]

might try 'em in four corners if you have a place to set them (while you're in the
experimenting mood), & turn the 4312's -way- down :D ... seriously...

I knew my "tower" would provoke a few good laughs :applaud:

[pelly3s]

nothing like getting really god damn loud for no reason at all. although it is looking to be a phase nightmare

[invstbiker]

If there is a "phase" issue here, it would be new to me. +=+ and -=- on both sets. Actually, sounds pretty darn good :D AND I can think of plenty of reasons to get loud :band:

[pelly3s]

i meant phase as in relation to allignment of the drivers
