Sure it is. Damping and current play a bigger role than rated wpc. However, since you have no problems, then other issues are the more likely cause. Another possibility would be he's cranking the volume too high.

True... but as I said, I run an identical amp Jesse with no problems, even when the volume is maxed out and have no control issues in my setup. It would stand to reason that he should not have issues from his amp, and drivers are most likely the cause. Phase issues could also have something to do with it, but my bet is a couple drivers need to be replaced.

I was pulling your chain about the 'stickler'. I would hope no one would be wanting to spray Karylin on these.
Sorry Vmax for the derailing.

I thought you must be messing with F1, no apologies neede...I needed the laugh..I am getting a bit frustrated. I know it will be worth it when I get there....

I appreciate all the input from everyone a lot!!

vmaxer, didn't you say you had two bad tweeters when you got the speakers home?

I still have 2 bad tweeters, working on getting a couple more SL 3000's until I can upgrade to the RDO 198-1's?? That wouldn't cause this would it?? By the way, I am now bi-amped, 405 to the tweets and 405 to the low's. No difference??

The problem is when I am cranking the volume, but certainly not as loud as the LSi 15's have been cranked?? I am sure they should be able to put out more volume than I am able to get. I played each driver at reasonably high volumes connected directly to my speaker output and they all sounded okay???Not sure what to listen for except a difference?? The drivers all checked about the same resistance..the 6511 are about 3.5 and the 6503 are about 7.0.

I am going to assemble the left unit and try again...I am at a loss, unless I have an amp issue??

I am open to any ans all suggestions.

Thanks a lot.

The tweeters that are dead are the loudest of the four in each channel. I would think that they could definitely cause your problem.

That would make my larger drivers pop?? By the way I swapped the bottom 2 tweetrers out, not the one not working is the very bottom one.

Are you sure there are no air leaks?

I'm confused. Is it the third tweeter from the top that are bad?

Nope, not sure. What's the best way to check for them??

It was, but I swapped them out with the bottom tweeter. Now the bottom tweeter is dead.

Press in gently on the passive radiator and hold it in. The mids should come forward and slowly return back to normal over a 2 1/2 to 3 second time period.

That checks out good, about 3 sec maybe a bit more or less??

I unhooked the input for the tweets and they still pop...

vmaxer

I'm going to take a break...getting too frustrated and that won't help anything.

nooshinjohn

take a look at the outside drivers, second from the top... I had to replace these drivers before on my original set of TL's...

When the original owner fried the tweeter he may have fried a component on the crossover.

I'm about afraid to ask how to check the crossovers....But I will...

How??

hearingimpared

I'm rethiinking this and the chances of both crossovers getting fried is slim. It may be that your amp can't handle the load with the fried tweeters.

You have to replace the tweeters anyway so you may as well wait to put the new ones in to see what happens. That is unless someone else has a better idea.

Unscrew the crossover cover plates and remove the crossovers.

Check for any visible damage to the caps and/or resistors.

There is a document here someplace that will tell you what are the values you should get when testing every cap, resistor & choke of the crossovers with a ohm meter.

I tried to locate it but I could not find it.

Thanks, I will look for it.

Meanwhile, I was testing and found that my interconnect cable somehow bit the dust....No continuity from blade to blade, but there is from pin to pin...

When you have the cable hooked up (and working) which drivers should get input from the cable.

If I unhook the speaker wires and just hook up the cable, which drivers should play??

What ohm rating are these speakers?? I thought they were 8??

Would the fact that these use a interconnect cable increase the chances??

I think on the pin / blade, the pins only are connected. The blades are dummies.

vmaxer

Just another thought to make sure I'm not expecting too much....

These big guys against a set of LSi 15's with upgraded crossovers by Ben....which ones should perform the best in sound quality and SPL.....

Currently the LSi's kick the big boys ****......:eek::eek:I just have a hard time believing that this is expected and normal...I realize I have 2 bad tweeters but...........

I don't have a lot of experience comparing speakers???

There is no input from one speaker to the other this way???

Also, look at this schematic. Don't look like a dummy connection??

george daniel

I thought the blade was connected to the negative speaker terminal.

This is correct.

hearingimpared

To avoid confusions there is no continuity from blade to blade. The blade side of the socket is connected to the lower negative post.

vmaxer

Well, I must have other issues....If I connect the cable and disconnect the inputs from one speaker it is dead. Before it would play some from the interconnect. Now, if I connect the blades from speaker to speaker the disconnected speaker plays???

Man is this confusing???

No disrespect to the LSi15's, but the 1.2TL's should completely outperform them on all levels. There are two many things going on at the moment. I suggest you get the two tweeters replaced as Hearingimpaired suggested and put everything together as though you just set them up again for the first time. It sounds as though you are chasing to many gremlins at once rather than focusing on each as a specific concern. Let's just deal with one at a time.

george daniel

I think that you may need to step away from them for awhile,,sound like you are starting to chase your tail.Put em' back like they were and start resolving one issue at a time,or some type of methodical approach. Good luck.Don't take this wrong, but have you owned SDA's before,or is this you first set?

I agree, but the interconnect thing has me confused now.

Thanks again

This is my first set,,,believe me I need a break from them, but then I am anxious to hear what they are capable of.

Maybe a beer or two and back at it...

Jerry,

I've been thinking about your offer, maybe you could send the Carver Silver 9t's and Carver Amazings for comparrisons...should have them back to you before you retire:eek:
