Default Reducing tweeter volume on Usher s520

Hi,

I'm not sure if this question belongs here as I have little to no experience in such things...

I have a pair of Usher s520 speakers, on which I would like to reduce the volume outputted by the tweeter. I find the tweeter a bit too obvious and would like to "pull it down" a bit without changing its sound.

Is this possible without opening the speakers by connecting a resistor across the terminals on the back or some such solution?

Any suggestions or advice would be very welcome!

Thanks

Try mount a piece of thin single layer toilet paper in front of the tweeter
Doesnt look good
But if you use front cloth its no problem

For experimentation, maybe you could try bi-amping and controlling your tweeters that way.

I have the same speaker and biamping let me control the amount of tweeter volume.

Unfortunately Bi-amping is not an option for me. Id also rather not resort to a piece of toilet paper!

I was reading about L-pads and wondered if I could use one of the L-pad calculators on the internet to give me resistor values and then connect one between LF and HF terminals on the back of the speakers and one between the + and - HF terminals?

Would that work to reduce tweeter volume?

Those speakers are bi-wireable, correct? I would try removing the strap between the two plus inputs and connect a 1-2 ohm (a few watt) resistor in its place. (Make your speaker cable connection to the woofer inputs.)

That will pad your tweeter minimally and effect the crossover minimally.

Give that a try.

Cheers,

Dave.

Excellent, that sounds simple and cheap to try! Is it not necessary then to connect another resistor between the tweeter's binding posts? I read on a few websites that if you just put a resistor in series then you will effect the crossover frequency.

Actually when connecting the speaker with one set of cables to the woofer terminals would it not be incorrect to place a resistor in parallel with the tweeter terminals? In this case would the resistor not be in parallel with both speaker drivers and effect both rather than just the tweeter? My circuit theory is a bit rusty....

If you put the resistor before the xover components you won't affect the xover freq

That solves it

Hmm, maybe thats the point of having biwire terminals

Lets us know how it turns out
