Question about Paradigm Audio Players & Recorders

Open Question

I have CT110 Paradigm Cinema speaker System. Last few days my subwoofer starts to making vibration noises little after I turn the woofer on. The vibration noise comes on and off. First I thought my neighbors upstairs doing laundry than I realized it was my woofer :). Woofer do power on every time so I don't think its the amplifier. It may be speaker?.

SOURCE: MACKIE SWA1801--Sound quality is not same

Hi,
First, Try the "defective" woofer in the cabinet that works well to be sure the woofer is OK.
If the woofer sounds good in the other cab, look to the power amplifier board : you have to test 2 fuses and 2 transistors witch are connected to the fuses : a defective transistor let your subwoofer work fine to half power, but distortion appear if you push away...

SOURCE: left speaker LED flashing, woofer and tweeter clicking...

The flashing blue LED and loss of sound on the Alesis M1 powered monitor is caused by failure of capacitor C8 (220uF, 35V) on the power supply board. It dries up due to its proximity to resistor R4 (47K, 2 W) which gets very hot. This is a design fault.

Remove the power supply board (4 corner screws and 2 mains connector screws) and disconnect the two plugs. Carefully desolder C8 and replace it. Its value is not critical (220 to 470 uF will do) but it should be a 105 deg. type, preferably at 50V.

Remove R4 and replace it with a similar resistor with its leads bent so that it is nowhere near C8, otherwise the fault will return. One end may be connected to one of the existing R4 solder pads (furthest from rear of board), and the other to the top end of resistor R3. Check that you have connected it correctly by inspecting the PCB tracks.

Replace the board and all screws and plugs before testing.

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: Boston Acoustics VR960 Crackle

I just finished repairing one of my VR960 units with a similar problem. My problem was that the sub would crackle no matter what input level. After changing a few of the active components, I finally discovered it to be a capacitor which was faulty. Anyway, I replaced the three 100uf 25V capacitors on the main board and all was well.

Good Luck.

I have a pair of Paradigm Monitor 3 V.2 High Def speakers for my front L&R home theater system. On speaker sounds very tinny with no bottom end. On inspection neither the main or tweeter loo


A few questions to help me help you: (1) Does the woofer cone move freely when you use your hands to move it (or do you feel friction)? (2) have you tried swapping the left speaker for the right to rule out the receiver as a cause?

Why does our subwoofer all of a sudden start to buzz when we turn on our stereo/home theatre system on?


Well if it buzzes only for a couple minutes after turn on then it could be when the woofer starts pumping it produces pressure in the cabinet which creates a bonding motion that then closes the cracks, kinda like glue. Like blowing a balloon up in a box. The balloon is the pressure, OR Yes it could be your woofer is going bad. All speakers have voice coils. Tiny wire wrapped around a thin layer of cardboard then attached to the cone. This cone could be getting loose. But when the woofer heats up after a couple minutes it probably bonds the tiny wires so then the vibration or buzzing disappears. Over time woofers can die especially if it produces a lot of distortion, In a speakers life distortion kills and it doesn't matter how much power it can handle or how much money you spent on it.
Not all sub-woofers are alike. Some can handle the really low lows, and some can not. Check your settings too. Over time the vibration of the woofer will start to undo the glue, nails, screws, and even burn through the tiny wires in the voice coil. Oh and make your china crawl across the table... Have you been watching a lot more action movies? Some of the older woofers can't handle the newer digital deep bass frequencies... You may have to reconfigure your setup.

Paradigm pdr80 no sound


If it is a powered sub, the sub power supply may have failed. There might be an open fuse.

No base is coming from my Home sub woofer, It detects signal but very little noise comes from it.


You need to make sure everything is wired properly, make sure the device your playing the music off of has the capacity of 130 watts of sound, and check to make sure your system is set to play that woofer.

My Onkyo sub-woofer sounds like something is loose in it or rolling around...the sound is similar to shaking a can of spray paint. When I plug it in to the system it sounds crackly. If i turn the volume...


sub woofers are very powerful bass , with incredible sounding technology. your problem might be with the woofer wall around the circle. open the box and take the woofer out.Check if there is any tare over the corners of the cloth. sometimes there might be a crazy noise because of a little opening in the cloth caused by small tare.. if so better change it with a new 1 and make sure that the new cloth has guaranty

Tweeter works but not the woofer


Take out the woofer (disconnect it from all wires). Take a 9V battery and connect two leads to it. Tap the positive lead to the positive on your speaker while touching negative to negative. You should see the woofer move a little and make a little noise. Don't do it for longer than a second or two or you can burn up your speaker. If it doesn't move or make a noise, your woofer is blown.

How long should a powered sub woofer last? It's on 24/7, but is not abused with long, loud playing. Mostly regular TV.I have a Paradigm PS1000, about 10-12 years old.


There's no way of telling really! Even if something did go wrong there's no reason to say it couldn't be fixed very cheaply. It could last another 10 years or it could go wrong in the next few hours.
I will say one thing after 12 years of service and never off you certainly have had your monies worth!

Paradigm 5.1 to 7.1 system


The Dolby curcuit in the Paradigm must be Dolby 7.1 or it will simply not be able to send the extra channel signals to the speakers. In otherwords you will not get the full 7.1 sound from two speakers added to a 5.1 amp.
