SOURCE: sr7200 LFE (sub woofer) output stopped working

Chances are if The Receiver only has sound in Stereo Direct Mode and all surround modes and Sub out are Inop the DSP (Digital Signal Processing) Card is most likey defective. These boards are not available from marantz (D&M Holdings) and must be Component level repaired which usually is not cheap. If Only the Sub out is not working check setup to be sure sub woofer is set for on. Also If On Screen setup menu does not appear on video monitor Unit may need to be Reset manually which entails discharging a Capaitor on main P.C.B Contact kstahl65@att.net for details

SOURCE: bose acousticmass 15 sub-woofer making a noise

The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

SOURCE: My HKTS 7 Sub woofer makes no noise,the led burns

Subwoofer is center speaker from A+B speaker signals. first check your wire to the receiver. Otherwise you need electronics service on the amplifier inside the speaker.

I have a JBL Venue sub12.It pops and crackles at certain levels.Ive had it for 5-6 years, dont use it much. Ive turned the volume down on the speaker to the lowest setting and it still makes the noise


It is hard to diagnose without seeing it, but most likely you need a new amp. We have them in stock. http://reconingspeakers.com/product/jbl-sub-12-amplifier-assembly/

JBL PB12 will have loud thump or pop!


First try to find the source of your problem. The easiest way would be to try your sub with a different audio source to see if the problem still occurs but is sounds more like there's a problem with the receiver.

Subwoofer will not product sound. (ignore product)


Please verify that we're talking about a JBL PSW-D110 here. I'm making no assumptions.

Are you running the Ipod into its L & R RCA jacks as prescribed?

Have you tried it with something besides the Ipod? A sub isn't supposed to reproduce a full range signal. Come to think of it, is the Ipod even outputting anything within the sub's operational range? I don't expect a lot of real bass comes out of one.

Perhaps you could try adjusting the Low Pass up to 180 to see if anything anywhere near the 'real' bass region is present.

Bottom line: There's not a lot of need for a sub (and no other speakers) running off of any music sound source. You wouldn't hear anything above 180hz.

JBL PB10 subwoofer sounds distorted and lights on the front flash


More likely to be the Class D power amp module, but you should look through the service manual to make sure all the parts are installed correctly. My PB10 AMP module went out and you cannot get one anymore.

Amp is on, but sub wont produce any bass


Make sure the subwoofer is set to low frequency, make sure subwoofer and bass are enabled on the headdeck. Make sure the gain is turned up on the amp, make sure the rcas haven't come out of the back of the head deck.

Noise when it turns on


have you checked your music source? Some systems like computers have a sort of output first before normalizing, which isn't your powered subs or powered amps problem. Try plugging in a regular solid state player like an ipod if the humming is still there when automatically turning on or off...
