As far as replacing the dvd any dvd player will work, as far as your LCR speakers go ( left, center, right ) it would be best to replace them with the same ones that came with the whole system, at least you want them to be same in size, power, and manufacture relative to the 2 rear speakers, at the very least the replacements should be same in size and power relative to the originals even if not from same manufacturer so as to attain relative level balance with the rear speakers, at the very very least any LCR replacement speakers will do really. The main point is keeping the relative balance between the LCR and rear speakers, the sub can be adjusted on its own. Sorry to hear about your theft by the way, that sucks.

    You may want to consider replacing the LCR's with ones that have individual volume controls on them to keep the overall balance between LCR's and rears, higher quality speakers generally have this feature.
    Since all 5 speakers in a 5.1 system are the same really it doesn't matter, the .1 in a 5.1 system means 1/10th of a bandwidth and that is the sub because it only needs to transduce 1/10th the bandwidth of regular speakers.

    To clarify, I mean that if one wants a 5.1 monitor setup then one need only buy 5 same monitors and a sub, the monitors themselves have nothing left, center, right, or rears about them, left, center, right, and rears has to do with the matrix in the amplifier/ reciever and not the monitors themselves, so one could buy 5 of the same monitors.
    Personally unless you are hooked on bose there are many far better monitors you could buy for your system, so it doesn't have to be bose, I recommend dynaudios but they are not cheap.

I wish to replace a subwoofer on a surround sound system


In most surround sound systems the sub woofer is powered separately and uses a standard RCA coax connection to the receiver/amplifier.

Replacing is simply plugging in the new and reconnecting the coax cable.

Usually the audio signal is Dolby Digital 5.1 the (.1) is the LFE Sub-woofer. The connection is between the Subwoofer RCA connector on the amplifier and connects to the (LFE-Line) in on the subwoofer speaker.

Hope this helps?

How to set up a seven-speaker home theater system


Set up a home theater

How to connect your speakers

In order to deliver surround sound, home theater systems require 5, 6, or even 7 speakers--and that's not even counting the subwoofer. Connecting all those speakers together can be quite a challenge, so here's a quick overview of the basics.

If you don't have an all-in-one, home-theater-in-a-box system, you'll probably need to supply your own speaker cables. There are several different types available--they vary in terms of wire size (or gauges) and termination types. Make sure you pick cable that's a good match for your speakers and receiver. And make sure they're long enough; the rear-channel cables in particular will be stretching all the way around the room.

Once you've selected your system and have all your speakers ready to set up, begin by placing each speaker at or near its intended location. Then, attach the cables to them one by one. After securely fastening one end of the cable to the speaker, connect the other end to the appropriate speaker output on the back of the A/V receiver. Be sure to connect the cable to the correctly labeled output.

For instance, the front-right speaker wire needs to go to the terminal labeled front-right. Also, make sure that each speaker connection is in phase, meaning negative to negative and positive to positive. Otherwise, your system's sound will sound out of whack. Repeat the process for every speaker in your system. Note that the subwoofer uses a coaxial-style RCA cable instead of standard speaker wire.

Once all the wires are connected, you should test the system with several DVDs and CDs, to ensure that everything is in working order.

For our first example, we used an elaborate 7.1-channel system, so it may have 1, 2, or several more speakers than your system. Some systems even employ wireless rear speakers, or virtual surround-surround modes that simulate multichannel experience from 3, 2, or even 1 speaker. And some listeners still prefer good old stereo sound from 2 speakers. No matter what type of speaker setup you prefer, however, the wiring basics remain the same.

How to position surround-sound speakers and a subwoofer
To get the best performance from a surround-sound speaker system, you must install each speaker in the correct location. There are three basic types of surround-sound speaker systems.

  • The 5.1-channel system has five satellite speakers and a subwoofer.

  • 6.1-channel systems have six satellites and a subwoofer.

  • And 7.1-channel systems have seven satellites and a subwoofer.

Start by placing the center speaker either directly above or directly below your TV. The center speaker can be perched atop a direct-view TV or mounted on the wall. Aim the center speaker at ear level.

In most cases, the front-left and front-right speakers can be wall mounted or placed on stands. However, if your speakers have rear-panel bass ports, they should not be wall mounted. Space your front-left and front-right speakers the same distance apart as the distance between your center speaker and your listening position. Position the front-left and front-right speakers no more than two feet above or below the front-center speaker. The tweeters in the front-left and front-right speakers should be roughly at ear level relative to your seating position.

Ideally, the surround-left and surround-right speakers should be mounted on the side walls of your room, slightly behind or parallel to your listening position. If your speakers have rear-panel bass ports, place them on stands instead. If installing the speakers on the side walls isn't practical, you can mount them on the room's rear wall or place them on stands behind your listening position. The surround speakers can be installed up to two feet above the front speakers.

Also, 6.1 surround systems have a back-center speaker. You'll typically mount this on the rear wall of your room, centered behind your seating position. Position the back-center speaker no more than six feet behind the surround-left and surround-right speakers. If your speaker has a rear-panel bass port or if the rear wall is too far behind your seating position, place the back center speaker on a stand instead. The back-center speaker should be installed at the same height as the surround-left and surround-right speakers.

Instead of a single back speaker, 7.1 surround systems use a back-left and a back-right speaker. These, too, are typically mounted on the rear wall of your room. Position the back-left and back-right speakers so that each is approximately aligned with the left and right edges of your listening position. Place the back-left and back-right speakers no more than six feet behind the surround-left and surround-right speakers. If your speakers have rear-panel bass ports,or if the rear wall is too far behind your seating position, place the speakers on stands instead. Install the back-left and back-right speakers at the same height as the surround-left and surround-right speakers.

A subwoofer is the last component of a 5, 6, or 7.1 system. Because bass frequencies are nondirectional, you can place the subwoofer in various locations. You may get the best performance by installing the subwoofer in the front of the room, approximately six inches from the wall. If you want more bass, try placing the sub near a corner in the front of the room.

Connect your DVD player to your A/V receiver--digitally
To hear a movie's soundtrack in surround sound, you must first connect your DVD player to an A/V surround-sound receiver. You'll need to make what is called a multi-channel-compatible connection.

The easiest way to do this is to use a cable that carries a digital signal. There are two digital options: optical and coaxial.

An optical digital connection, also called TosLink, uses pulses of light to deliver a digital signal. According to some experts, one advantage of optical digital connections is that optical cables don't pick up noise, while lower-quality coaxial cables can. Many, but not all, DVD players have an optical output. Most A/V receivers have at least one and usually multiple optical inputs. Plug one end of the optical cable into the DVDs player's optical-out jack. Plug the other end into the receiver's optical input.

Finally, you need to tell your receiver to use the optical connection whenever you switch to the DVD input. This is called assigning the input. Information about this simple process can be found in your A/V receiver's manual.

A second option is a coaxial digital connection. This type of connection is also used for cable TV, but the connectors are different. This type of coaxial cable has an RCA connector. Coaxial cables are less expensive than optical ones. In fact, you can use any old RCA cable to make a coaxial digital connection, and you won't lose any audio quality.

Most, but not all, DVD players, have a coaxial output. Some have coaxial and optical outputs, so you get a choice. Audiophiles argue over which connection is better, but it's very hard to hear the difference. Most A/V receivers have at least one and usually multiple coaxial inputs. Plug one end of the coaxial cable into the DVD player's coaxial-out jack. Plug the other end into the receiver's coaxial input.

Finally, tell your receiver to use the coaxial connection whenever you switch to the DVD input. Again, your A/V receiver's manual will have instructions for assigning an input.

My bose cinemate 1 sr has a flashing red light and no sound. does not change to green light with sound.


This is a powered sub-woofer, with a complementary sound bar. The amplifier for the sub and the sound bar, are in the sub cabinet. Because there are multiple speakers in the sound bar and sub, there are multiple amplifiers to run them. If any, or all of the amplifiers are damaged, they generally have a condition known as DC Offset. There are sensor transistors on each of these amplifiers, which will "report" a damaged amplifier condition back to a microprocessor(computer inside the Bose system). When this damaged condition is identified, the amplifier will shut down the system, and that red indicator will flash. You will need a professional, audio specific technician, as this is not a DIY repair.

If any of you are interested in having your systems repaired, please contact me from my website, audioserviceclinic.com. Just FYI, this is not a Bose specific issue. The same problem can occur with any amplifier, any brand. Thank you.

My bose ps28 is making a rattling noise whenever bass is involved. How do i fix it?


You have lost the sponge roll surround of your subwoofer ( suspension ). Its known as foam rot.
Either you can buy new woofer drivers for the subwoofer or repair the surround alone. Kits are available. But you will need some technical skill.Check out this link.

I have a Lifestyle 35 and want to replace head unit with a 5.1 receiver. The Bose subwoofer model LSPS uses a network type cable connector on the sub side and a male din plug on the head unit side of...


The entire 5.1 amplification system, in the Bose Lifestyle 35, is actually part of the Bose Acoustimass (subwoofer) module. The RJ-45 (network type) connector passes a low-voltage signal from the console to the Acoustimass module. If you were to hack the connection, and plug the speaker outputs of a 5.1 receiver to the RJ-45 socket on the Acoustimass module, you would blow the amplifier.

If you are really itching to replace the Bose Lifestyle 35 console with a regular 5.1 receiver, I strongly suggest you sell your Bose system, and purchase a Bose speaker system, such as the Acoustimass 10 Home Theater Speaker System, which is made for use with a standard 5.1 surround sound receiver.

I have a subwoofer with standard speaker wire connection, how to I attach to a receiver with a subwoofer cable?


The Subwoofer is Likely Passive....meaning no amplifier is within the enclosure itself....the incompatible connectors mean you cannot connect the subwoofer itself to your surround sound system.

look for a Suitable stand-alone (1 Channel) Amplifer with sufficent power.....connect the RCA Imputs (subwoofer cable) to the Recievers RCA subwoofer output....then connect the amplifier's output to the the wire going into the subwoofer enclosure....if there is a plastic connector simply cut it off and strip the wires down a sufficent lenght....then secure the wires to the output of the amplifier.

if you do this make sure you know the ohm rating of the subwoofer and the minimum ohm rating of the amplifier your using.

No surround sound


It sounds like the speaker wires are mixed up or maybe a setting on the reciever is wrong. Verify your speakers are properly connected. you test speakers using a 9 volt battery or smaller.

No sound from rear/ surround speakers on Bose V20


Yes, very easy and cheap if you get it from the right place. Fiber Optic going from the output of the device to the input of the receiver. If your lucky enough to have an input/output fiberoptic in your tv, run the fiber from the device to the tv input, fiber the output of the tv to the receiver so not only are you getting the device full surround sound, but you'll also get better TV surround sound for those that are made with Dolby pro logic II sound. (pretty much all the newer movies and shows)

Bac speaker bose 321


The arrays from this system are only designed to run with the Bose Acoustimass / subwoofer, which in turn will only work with the Bose DVD player. If you use them directly to an amplifier, they'll sound poor / wierd and you probably blow the drivers. You might even damage your amp.

Each speaker has 2 drivers firing in slightly different directions. The idea is (when its used with the 321 system), the inward speakers give a mix of front and centre, the outer drivers give a mix of front and rear. A normal amp won't do this....
