Question about Bose Acoustimass 5 III System

1 Answer

Opening the main speaker cabinet ..... AAAHHHH!

I have to make a simple repair of one of the speaker wire connectors but cannot figure out how to get into the cabinet. You know, the big base unit with the amplifier. I have pried, pushed and invaded the tiny line between the amplifier with all the connectors and the speaker acoustic chamber. Can some one tell me the trick? Thanks for reading. DJ

Found the solution here: My version of the procedure is this: First pull off the knobs for treble and bass controls. Then look at the opposite end of the plastic cover to where you plug the leads in. In the gap between the plactic cover and the main case you should see a thin, notched piece of plastic (a half-wheel). Use something narrow (toothpick, very small screwdriver) to turn this thing using the notches in it until a triangular piece sticks up through the gap. Once this is showing, give the plastic cover a sharp whack on this same end, pushing towards the end where the leads plug in. It slides off once it has moved a centimeter in that direction, clearing a couple of bumps that hold it in place.

Impute jack on a kick back type cabinet. need to remove amp from cabinet to repair.

Very simple. Remove all black screws at top and sides of cabinet. Gently slide the amp unit out (towards rear). Done! :)
Don't be alarmed if you have to "tug" on it a bit. This is normal. Just don't try to "FORCE" it out.

How to open the enclosure???

Many speaker enclosures are glued together - this helps prevent vibrations of cabinet panels. Many panels are made of particle board, covered with a simple veneer. Disassembling the enclosure would likely be destructive.

The best way in, turns out to be via the largest driver - or woofer. The woofer is the largest speaker in the cabinet and is usually held in place by 4 screws. It can be removed without (or with only minimal) damage to the cabinet after removal of the screws with a screwdriver. Use of a battery operated screwdriver is discouraged due to the possibility of stripping the holes in the particle board. Once the screws are out, you might need to gently pry the outer edge of the woofer's metal frame from the cabinet with a small screwdriver to separate them.

Be prepared for the speaker to come spilling out of the cabinet. Wires on the speaker - if to be disconnected - should labeled as to which terminal they are connected - so the speaker will be in phase when reconnected. All wires to be disconnected should be labeled first! You may find filler material (looks like a thick fiberglass blanket) and crossover components (coils & capacitors) along with the additional wires between the crossover components and other speakers in the cabinet. Be careful to not accidentally disconnect wires from the internal components if you need to remove the filler material.

These are tips for opening most speaker cabinets - yours may differ slightly. Hopefully, this helps. Please rate this reply - thanks!

How do I hook up banana plugs to a infinity PC 350 speaker

The illustration in the manual I found at isn't detailed enough to show the axial connection option, which would normally accept a banana plug inserted straight in if the opening is conductive and about 4mm wide. I suspect it is as they mention a "variety of wire connectors".

Their only illustrated example show bares wire ends inserted into a small hole drilled through the termial post and the red or black plastic piece tightened down to secure it.

IMPORTANT: Make sure all equipment is turned off before making any connections.
For speaker connections, use a minimum #16-gauge speaker wire with polarity coding.The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +).
NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options.
The speakers have coded terminals that accept a variety of wire connectors. The most common connection is shown in Figure 5.
To ensure proper polarity, connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker, as shown in Figure 6. Connect the – (black) terminals in a similar way.
See the owner’s guides that were included with your amplifier, receiver and television to confirm connection procedures.
IMPORTANT: Do not reverse polarities (i.e., + to – or – to +) when making connections. Doing so will cause poor imaging and diminished bass response.

Which speaker wires feed which speakers throughout my house?

Since this is a custom install and the wires don't follow a rule the only way to find which is which is to disconnect all the remaining speakers, plug in light bulbs in their places and check every single pair till they all match and their corresponding bulb lights up.

Need to know how i can set up the diffrent settings on my yamaha

The answer to this problem should be in the owners manual for your product. Check the speaker wire connections and the speaker wire for possible broken connection points. Try moving the wire around and see if you get sound. If you do then you need to replace the speaker wire. If not then you need the connectors you are using on the wire that are making contact with the speaker and receiver. They all must be making good contact with the speaker wire to keep a good connection.if you find no problem with the speaker wire and the connectors, you need to try another speaker on the the wires to make sure that the connection is working.If all the connections are good and you are getting signal from the output, you have a problem with the speaker. If you have a warranty for your speakers then have the bad one repaired or replaced under warranty. If not you can try to repair the speaker by opening the cabinet and checking the input connections from the Input wire connector to the speaker. See if it has any cold solder joints that may not be connecting the signal to the speaker. If the connections look good.You need to look at the speaker itself and the electronics that may be use in sending the signal into the speaker. Look for bad or broken connections in the speaker and the components. The drive circuit may have failed and need replacing or the speaker itself may have a broken or a burnt coil. If this is the case you may want to replace the speaker. Take all the information printed on the speaker and the information in the owners manual on the speakers and write them down on paper and try to find a speaker that matches the specification. Buy it and replace it for the bad speaker.You can find information on you receiver on the website by using the customer service section and putting in the model number of your receiver. Check out the frequently asked questions and troubleshooting sections and see if someone else has had this problem or similar one and has had a solution printed.The number for Yamaha service centers is 1-800-492-6242 and for buying parts is 1-714-522-9888. You can use these numbers to get help from the service center in your area or buy parts for repairs from the dealers. I hope this helps you with your problem.

How do i open the speaker to reconecct the wires inside?

It may not be only wires loose; the speaker(or speakers) may be damaged.

The common 'dynamic' speaker has a centered magnet in an assembly that extends the field of the magnet around a coil of wire on a form called the 'voice coil' that is firmly attached to the cone which moves in and out to 'pump' air and produce sound.
The clearances (gap) between the magnet assembly and the voice coil that sits in a narrow space between the magnet and the outer field piece is very small and critical.

Once positioned in the factory, glue is used to keep the field assembly from slipping and rubbing against the voice coil.

A strong shock will break the glue bond and, if severe enough, clamp the voice coil so it cannot move freely any more.

Since the Bose is a quality product, the cabinet may be assembled with glue and screws that are concealed.

If you know someone with a simple multimeter, they may be able to check at the terminals to see if there is any continuity from the terminals to the speaker.
If it doesn't have any, then perhaps only a wire is broken between the terminals and the speakers.
There is with high probability also a filter inside that separates the frequency range and sends the signal to separate speakers that produce different ranges of sound.
