    If your getting the 198's do what i did. I put 1 in & listened to it & compared. It took me 20 seconds to shut it down & put the other one in quickly. I didnt think id notice. Was i wrong. You will thank yourself latter :)

    im excited, cant wait to get the new tweeters. my refurbished and upgraded carver 1.0 will be here in about two weeks. If you ever get a chance to get the 1.0 you will love it. I bought the adcom to tide me over until it gets here.

    They are nice speakers. Currently have then in my HT set up. Got my Monitor 5s in 2 channel duty.

    Enjoy friend!

    I had a Adcom 555 hooked to the 15tl's for 2 weeks or so & i tried the Yamaha & now the Adcom is in the closet. Adcoms pair excellent with SDA's but to me it didnt with the rta. I had a Carver receiver & loved it. But i used it on Paradigms. Pure bliss

    yeah, you are probably correct. It's just strange that the other speaker does not trigger the relay. Thanks.

    That is the key to solving the issue. What is different between 2 seemingly identical speakers.
    If one speaker does it for sure and the other does not for sure, you have narrowed down the possible or potential issues at hand.

    Ouch....way too much man. If sticky fingers on the volume dial is a hard to break habit, maybe Pro speakers are up your alley.

    Ha! Why is that too much? the amp is 100 watts per channel and it is not clipping/distorting. The speakers are rated at 250 watts.

    An amp will begin to square off waves before you hear audible distortion.

    Oh, there's a ton of reasons, many of which we've gone over a gazillion times. Do a search here on properly powering speakers or clipping, grab a sandwich and a coke and read up a bit.

    Are we missing one huge issue?

    He said only one speaker causes the issue, when he switches to the other speaker, the issue goes away..........

    So logically, that would put the issue entirely with that one speaker, rite?

    That or the one channel in the amp. Need to know specifics on how it was tested. The only thing I can think of is a speaker terminal short or internal wiring. Both would require inspecting the tweet and two mid drivers.

    Yes it would, and most likely a poly switch. My comment was aimed at the 2 0'clock volume he said was used.

    Maybe he's expecting to use 100% of the volume dial, I dunno, but I can see he needs a better grasp on things or this problem will continue for him. Just tryin' to save the man some coin down the road.

    he said the other speaker does not do it on EITHER channel of amp a page or two back though.

    Regardless of his issue he's turning the volume dial up too loud, that's what we're talking about.

    Ha! you guys are funny. You are telling me that im turning my **** up to loud based on a little white dot on a knob. Trust me its not too loud. The amp is no where near clipping. The speakers sound clean and tight. You have no idea what the output of my turntable is or the preamp. That is like saying your amp is louder because it goes to eleven and mine only goes to ten. LOL!

    It's obvious you have a LOT to learn about audio gear and we are trying to help you do that, but you're not listening.

    Hi derwood,
    It does sound as though the amp is reacting to a short since it is happening as soon as you reach a certain level with no audible distortion. If you have access to a fairly good volt/ohm meter try measuring the DC resistance of both speakers. One might be considerably lower than the other.
    The point about the volume control is that under normal circumstances with a line level source, such as a CD player, a preamp's volume control when set to around 12:00 o'clock will produce enough output voltage to cause most power amps to reach full output. So, as a general guideline it is recommended that playing volumes be kept lower than 12:00 o'clock to avoid harmful distortion.
    When considering phonograph sources there can be many variables that make this difficult to equate to volume position, cartridge output being the main one. Then listening for harshness or a brittle quality to the way upper frequencies are reproduced is the best method to detect distortion.
    I hope this is helpful.
    Regards, Ken

    Trying to get back on track.

    @derwood Don't give up yet! :) Sometimes threads can get off track and things get overlooked especially when there are some trigger words. Its the internet. :o

    I thought you checked the resistance, but I can't find that post. If you have not checked the resistance, that is the first thing to check. If the resistance is the same, I would vote that it could be the polyswitch as well. If you had an amp without the protection circuit then if I recall only the tweeter on the speaker would cut out. The tripping of the polyswitch won't harm an amp, but it could be fooling the Adcom for a split second. I believe you can jump the polyswitch, at least for testing purposes.

    You have some great speakers and are on the right path with the RDO-198 tweeters and the crossover upgrades. Some people replace the polyswitch when upgrading the crossovers just in case there is an issue, and some eliminate it because it becomes the lowest quality part in the crossover. If you eliminate it, then a resistor value in the circuit needs to be increased to compensate for the missing polyswitch. resistance. Stick around there is good information and enjoyment to be had here.
