Andre281503560612 Posted May 22, 2008 Posted May 22, 2008 dam this one has me stumped (and peeved!) Just got some new bookshelf speakers. The left speaker is acting up though. It sounds terrible, like the drivers are in a tiny tin can. Low bass, no clarity in vocals or instruments etc. Sounds like a phase issue right? I have them biamped and have checked the configuration more times than i care to disclose. I have checked all the connections, i am pretty confident it is connected right. Could is be faulty right out of the box? Just in case, here is how its setup (using some quad core cable, and configured to biamp in AVR menu) Front Right on amp is connected with solid red and black coloured cable to top terminals on right speaker. Front Left on amp is connected with striped red and black coloured cable to top terminals on left speaker Surround Back Right on amp connected with solid coloured cable to bottom terminals on Right speaker Surround Back left is connected with striped red and black cables to bottom terminals on left speaker. Please help!

Please help! Your configuration sounds correct. Rather than Bi-Amp them have you tried Single Amp for initial trial? For me I'd consider a couple of things: - Check your Speaker Cables. Any breaks? - Bare wire or Plugs? Check and re-check your cable connections. - Could be a faulty Crossover in one of the speakers. It's not uncommon to have a fault out of the box. - Could be a faulty driver in one of the speakers - What source / amplifier are you using? What speakers did you have connected before-hand and do they still work OK? Good luck at any rate and I'd be taking them back to retail if you cannot work out what the issue is. Cheers Blade
Andre281503560612 Posted May 22, 2008 Author Posted May 22, 2008 Cheers. - Check your Speaker Cables. Any breaks? - not that i can see. - Bare wire or Plugs? Check and re-check your cable connections. Bare wire, but all connected well - Could be a faulty Crossover in one of the speakers. It's not uncommon to have a fault out of the box. - Could be a faulty driver in one of the speakers - What source / amplifier are you using? What speakers did you have connected before-hand and do they still work OK? Denon 1906, will have to unpack the old speakers and give them a try! Thanks for the quick reply
Shonky* Posted May 22, 2008 Posted May 22, 2008 Easy thing to try. Swap the channels left and right at the amplifier. If the fault swaps sides it's the amp. If it stays it's the speakers (or cables). This doesn't cover the cabling which although unlikely to be faulty can be tested by swapping at the speaker end after the first test.

Very good points mate.
Andre281503560612 Posted May 22, 2008 Author Posted May 22, 2008 Ok ive now tried everything and its the speaker! I swapped the wires over on the speaker end, and the same speaker was still stuffed (the one sitting on my left). I then replaced the wires and it was still the one on the left. I then switched the wires over on the amp end (left into right and vice versa on both the A speaker and the bi amped "rear backs", again same speaker.
OakenShield1 Posted May 23, 2008 Posted May 23, 2008 Just a thought, it isn't out of phase is it? Maybe it has been wired wrong INSIDE the speaker, try swapping it over and see if that fixes it??
Andre281503560612 Posted May 23, 2008 Author Posted May 23, 2008 I wont be opening the speaker up. The importer (or whoever fixes the speakers on their behalf) was very helpful and said they would take a look at it for me, but i will be chasing it up with the store first. The manual says not open it up, and i dont want to do anything which might void the warranty.

Sounds like a problem with the speaker. No that it matters but put your ear to the mid-range/mid bass driver and see if there is any sound coming out of them. Sound like they may not be connected or not connected properly.

If you swap the OUTSIDE speakers wires over, it would tell you if they are right inside Ie wire it up out of phase... All good though, they shouold take it back too!

That was gonna be my suggestion too. I had a speaker where they had put the red and black caps on backwards, therefore it looks like you connect it right (red to red etc) but it isn't.
Trofius Posted May 23, 2008 Posted May 23, 2008 hope i dont insult, but are the shorting bars removed. SOunds like the main speaker is not working.
Andre281503560612 Posted May 23, 2008 Author Posted May 23, 2008 Took it back and he agreed something was wrong. Internal wiring or a driver or something. Apparently he is going to get it fixed. Not sure how much i like this outcome, given i bought them yesterday, but we will see what happens.

Andre281503560612 Posted May 23, 2008 Author Posted May 23, 2008 I think i misunderstood, looks like im getting a new pair after all. Different colour but i dont particularly mind.
Nolz Posted May 23, 2008 Posted May 23, 2008 Just a thought, it isn't out of phase is it? Maybe it has been wired wrong INSIDE the speaker, try swapping it over and see if that fixes it?? When I first started with his hobby I listened to my stand mounts for a few months with the speakers wired as indicated by the marks on the speaker and the colour of the terminals. It sounded ok, I didnt really pick out a problem. It wasn't until I moved them to be rear effects speakers for my HT did my receiver then tell me that they were wired incorrectly, indeed swapping the + - connections made the amp happy, and yielded the expected results. However I think Andre's problems sound more severe. I know with car audio speakers they the speaker wired in reverse would often sound a little harsh and lacked bass.
Andre281503560612 Posted May 23, 2008 Author Posted May 23, 2008 Im pretty certain something wasnt wired up solidly enough on the inside, or worse. Apart from not sounding right, occasionally it would also have a crackle sound or drop out for a split second. At any rate, ill be happy to receive a new pair shortly. Now only to decide whether or not i keep my subwoofer in the mix!
Nolz Posted May 23, 2008 Posted May 23, 2008 Upgraditis...isn't it a real bugger! If you are going to sell your sub, I'd list it over at stere.net also, I think you'll find that it'd get a fair bit of interest. I'm assuming it still doesn't sound right in your system?
Andre281503560612 Posted May 24, 2008 Author Posted May 24, 2008 No this is a different sub, the one i replaced in my HT setup with the cw-12. Its part of the Harman Kardon HKTS-11 sub/sat pack. I actually really like it. Its a 10" down firing and quite musical. Problem is if i want to sell my HK pack (doesnt appear to be all that much interest) this is the star of the show. My brother might take 4 of the speakers off my hands, but what am i gonna do with a subwoofer, 2 stands and a center channel! A nice 1.1 setup perhaps!
Andre281503560612 Posted May 28, 2008 Author Posted May 28, 2008 you wont believe this! The store arranged to have my speakers replaced. I got a new pair delivered straight from the warehouse. Guess what? Faulty also. One of the speakers has a kind of crackle. Its hard to explain, but some voices in particular sound very nasally, kind of like some tin is rattling in there. Switching from left to right speaker on Winamp you can tell instantly. I really cant explain it well, but theres something definitely wrong. Im sure the store is sick of me, but what to do? Should i just go to the repairer or back to the store?
Andre281503560612 Posted May 28, 2008 Author Posted May 28, 2008 (edited) before i really freak out, can anyone tell me this: If i move the slider for left or right channel, 100% of the way (so im either getting left channel only or right channel only) does the information for both channels come out of one speaker, or am i just getting left or right channel track? Its only really noticeable on the intro to this one song, so im thinking (hoping) the song might be mixed like this (its a video clip version of a song) EDIT - never mind i found the prob in another song also Edited May 28, 2008 by Andre28
Trofius Posted May 28, 2008 Posted May 28, 2008 Sounds like cash refund time and look for a different brand, or model.
Andre281503560612 Posted May 28, 2008 Author Posted May 28, 2008 Well ill ring, if they have the original pair i brought back (good chance they do) i will ask to take the good speaker from that pair and replace with this one i guess. I run so bad!
