A Speaker Doozy!! - Page 2

If you look at Ohm's website, you can see that they are selling the Ohm B as a kit for just about as much as they used to sell it for assembled. No wonder they're willing to give you 25% off.

From the Ohm Website under "Speaker Basics": If a loudspeaker has a crossover (where one part plays part of the range and another the rest) in this area, just the different size of the drivers will be audible on voices even with ''perfect'' design. Anything less than perfection will be even worse. The solution we found is that no crossover creates no problems.

I would assume that they would actually implement their solution in their speakers. Since they do use a super tweeter, there is probably some minimal xover work but not nearly the same full blown thing as in a conventional speaker. Their new speakers are probably very efficient.

But this isn't the speakers from today's manufacturing! These speakers are almost thirty years old.

I think they changed their designs a LITTLE over the last thirty years. The newest speakers don't have crossovers, but the Ohm B's were the first ones EVER manufactured by them, and I think they do have crossovers. Afterall, it's part of the kit for 55 dollars.

Are you suggesting, however, that I replace the tweeter instead of getting new speakers? I would do this, but I am not at all skilled in this area (never taken apart a speaker before) and for all I know there could be a million things wrong with the speakers. Would this be an easy thing to accomplish without any dangers of hurting myself or damaging the speaker even more?
Thanks!!

should be a cakewalk even for a beginner if you use the proper tool for the job.Can't tell from the pics if the tweeter has panel mount screws or if you need to open up the back also nothing bad or difficult as long as you dont strip the screws.
All you need do is pay attention to the polarity (red dot or +) of the speaker and which wire went to where.A simple two wire connection and usually with quick connects for easy on and off unless soldered-ask man.

Buying new will also be good and you will not have to worry if the woofer foam surround is up to par or one the verge of self destruction and caps do age and they ARe there in the crossover.

Option #3-buy the new speakers and keep these for a possible surround system.Always a good idea to have voice matched systems in a multichannel set-up and being from the same company they should play well together.


options man,always the options with me

Check your speaker cables for continuity and move them around while you do this. I have a feeling one of your cables is frayed inside..maybe even completely broken.

It wouldn't be a bad idea just to go in there are replace all the old cables and caps. If you have a friend who can solder, it should be a snap. Not hard, might take a bit of time's all.

So if the distortion is still happening on that one speaker, and I have switched around both the input channel and the speaker cable, it's the speakers and not the amp.. right?

Thanks!

It make logical sense. Have you opened the grill and check the speaker? For old speaker, the surround sometime will disintegrate.

The other things to check is the connect. Deoxit the binderpost. Check if it's loose. Sometimes they'll make intermittant short from the vibration of the speaker. Are you using spade or banana plug?. Banana plug has a tendency to be streched and not make good contact. Lastly check the crimping of the connector.

Well no wonder!

The speaker connectors are broken I think! I just looked, and I had hooked them up so that the wires were just touching, and there is absolutely no way to secure the connection, because the little circular objects you're supposed to screw to get it tight are broken! They turn the actual post instead of securing the wire. I think that is probably causing the distortion.

It doesn't matter the cause anymore, though, because if it IS the speakers's problem, a speaker upgrade would probably just be more worth my while.

Thanks!
