DIY speaker mod- Newbie Needs Advice.

There is a simple mod I want to try on my Snell speakers. It involves removing the attenuation knob on the rear of this speaker and bypassing the fuse. The tech said to replace this with a 1 ohm resistor. I am not kit builder but, thing I should be able to do the soldering. I do not know anything about the part. Can I just get any 1 ohm resistor at radio shack or is one type better than another?
Thanks in advance.

I have no clue on resistors. I generally just burn in anything by listening regularly (sometimes I'll leave the system running at a low volume while taking care of things in the other room). When I've got about 200 hours on whatever I'm burning in, I sit down for some in-depth critical listening, but generally I find things don't sound terrible during burn-in.

Someone else may have a better idea about the typical break-in regarding resistors. It might be a good idea for you to post the specific resistors you're going to use.

I am not replacing the fuse with a resistor. I am removing the fuse and replacing the potentiometer that controls the rear firing tweeter with a resistor.. The factory setting is 12:00 for a neutral setting and the 1 ohm resistor is supppose to match that value when the potentiometer is removed from the circuit. The dirty deed was done yesterday and sounds ok. My techie friend says this resistor will take about 20 hours to burn in. Will report back when burn in is complete. The mfg. is ok with this mod.

If that 12:00 setting your referring to is actually at the center of its full rotation, using a resistor that's 1/2 of the the potentiometers full value will most likely give you a more neutral setting. For example, if it's a 8 ohm pot, use a 4 ohm resistor, for a 20 ohm pot, use a 10 ohm resistor. This is the way a lot of speakers are wired.

You said you've done it and it sounds OK. So if it does seem too bright, try the half of the pot value method.

Make sure you use a wirewound, non-inductive resistor. Make sure it has a rating (wattage) as high as the pot itself. For a tweeter, I'm guessing a 10-20 watt wirewound resistor. Don't use a carbon, or a film type, unless a manufacturer says to for some reason.

Burn in complete and initial brightness has gone away. All is sounding good.
