PLEASE HELP! KLIPSCH SW110 SUB. NO SOUND!

post #1 of 9
Thread Starter 

Hello!

 

i'm going insane trying to figure out whats wrong with my setup!

 

I just returned my subwoofer thinking its defective! got a brand new sealed box replacement...

 

I started with a 15ft coaxial cable rated at 18awg its high quality cable.

everything done by the manuals, connected to the correct terminal; LFE, then to the sub line in of my yamaha rx-v657. When i go in speaker sound test, i could hear the sub but only when i turn the volume really high. But when I play music, sub doesn't output any sound. My front klipsch towers work perfectly. I tried both connections on my receiver(it has inputs for 2subs).

 

I have no idea what to do. i had a hkts210(similar to hkts200) sub and it worked perfectly with the receiver, it came with its own sub cable, but it was thinner rca type, not thick like coaxial cable i have.

 

isn't the sw110 supposed to be a better more powerful sub. i got it because i only paid $175 for it brand new!

 

i wrote to yamaha, and they don't know whats wrong.

 

am i using wrong cable?. I heard coaxial digital cable should work perfectly, supposed to be better than rca.

 

please help

please help

I don't know if your above is a typo, but you should be connecting to the Yamaha's sub out. On the back of the RX-V657, it's labeled; Pre-Out Sub Woofer.

Is the subwoofer levels slider in the AVR menu, turned up?

What all have you done to make sure everything is set properly?

The first thing I would do along with Bee’s suggestions are unplug your cable from the back of your receiver. Now turn your SW amp up and then tap the end of your cable (male pin) and see if you hear a thump thump. If so your cable is most likely fine and SW amp. Most likely a setting then.

thanks guys!

 

yes it makes a loud thump when i do that. but i just can't seem to get this thing to output any sound. its so strange, brand new sealed out of the box! receiver is also new only a month old. i have extended warranty on the receiver but i'm sure its not the receiver.

 

i have gone through its settings in ypao menu, sw is turned up. i've also ran the ypao mic setup few times. the rear of the sw has "gain" setting and its turned towards loudest. frequency range dial is at 80hz as recommended in sw manual.

 

maybe the speaker wire is too long? no clue. waiting for yamaha's tech reply. in their first email they said, try using "subwoofer cable" but i was told that the digital coaxial cable is enough.

 

i just have two rf-62 2s in the front and one sw110 sub for my small room. the towers are great but i wanted a bit more bass for movie scenes. frustrated. feel like throwing this sub out the window lol

Your sub is fine. Set your speakers to small in avr and set 80hz crossover frequency for a start. YPAO may have set them to Large; that's why you are not getting any response from sub during playback.

That did it!! I set the front speakers to Small in ypao setup.  sub freq.80hz

 

Wow amazing! this sub is overkill for my small room, 14'x14'x8'  i think itll put cracks in the walls lol
