SOURCE: Problem connecting Onkyo Amplifier to Bose Accoustimass speaker system

This is probably correct as modern equipment uses electronic volume controls rather than potential dividers the range is normally biased towards the bottom end so there is lots of the range that is quiet and a smaller part that is loud.

Unless you find that at the top of the volume range the system does not seem to be loud then it is probably correct. It is not uncommon for modern equipment to clip at 80 / 90% of the volume range. Where as old style equipment with volume pots used to clip at arround 30% of the volume range as it gave the apperance there was loads of extra volume available. In fact all that happened if you turned it up louder was it clipped more and more.

Regards,
Andrew

SOURCE: what receiver would do a good job on my bose

almost any model from Denon's new lineup.

here is a link to Denon

I have a 4310ci they retail for $1999.00 but I bought mine for $1299

A good rule of thumb is your receiver and your speakers should cost about the same.

other brands are:
Yamaha = pretty good
Onkyo = high failure rate
Sony = good quality but so so sound
Integra = same as Onkyo
Marantz = ok sound but so so quality

I should probably not point out that most Audiophiles look down upon the Bose corporation.

Bose was the first to introduce the satellite / subwoofer system to the market back in the early 80's and has a big presence in professional audio. However their design does not produce neither crisp highs nor substantial lows. the basics of audio are that sound is produced by moving air, the more air you move the more sound. Bose has definitly found a way to "cheat" by utilizing both forward and rearward motion of the cone by encosing it in their " accoustimass" module but many of the frequencies required for true clarity are merely lost due to the drivers inability to create them.

If you choose a receiver such as one from the Denon line they have a feature called "Audyssey" Audyssey uses a microphone to calculate room acoustics as well as to apply equalization to help make up for what the speaker isn't producing enough of.

Now usually when you disrespect Bose you always get someone upset and having sold Bose myself for YEARS I would only argue take a grill off. Instead of a high quality tweeter or woofer you will generally find a cheap paper component.

There is a purpose to me going off in a tangent about Bose. IF you are considering replacing your receiver because you feel that its not driving the speakers to your liking or maybe isn't "clear" enough then unfortunately my diagnosis isn't that you need a more powerful receiver but better speakers.

The purpose of upgrading a receiver should be more to get updated surround processing, better video distribution, multi room audio video etc..Unfortunatly unless you are trading up from a 80's low end: Pioneer, Technics, Kenwood, Sherwood or Sony the sound improvement won't be that great.

Sorry but hope that helps

SOURCE: sir my speaker bose 301

If they're all Bose 301-5's then you have the rare instance of matching speakers all around, so when sounds move around the room in a movie they don't change. I'm envious because even though I have Bose 901's (front) and 301's I don't have that exact match you have. The 301 sound is very good to my ears.

I assume you have them all set as LARGE speakers in the Pioneer, since they are capable of good bass and the parameter is more about Bass response than actual size.

If you added a subwoofer (which you may not need) you might fill in the lowest bass and effects channel.

SOURCE: Will a Bose SA-3 Amplifier work well with Bose 151 SE Speakers?

yes! the specs look good, in fact the amplifier output matches the speakers, plus the ohms ratio is fine.

How to connect Mackie Mixer 1402vlz4 to Bose Accoustimass 5 speaker


you need a power amplifier between the mixer and the speakers to actually drive the speakers. You would have to choose which amp to use (the manual, found here: http://www.bose.ca/controller?url=/shop_online/speakers/stereo_speakers/acoustimass_5/index.jsp#manuals suggests between 10-200 WRMS for power), and thus would have to determine the cabling options depending on the amp you choose, but...go from either the MAIN or CONTROL ROOM outputs of the Mackie mixer into the inputs of the power amp. Then go from the outputs of the power amp to the inputs on the Acoustimass bass module, which also runs the Acoustimass satellite speakers.

I have a bose accoustimass 3 i'v connected it to both rear and main outs but still the sub sounds muffled very very quiet and no low base at all if it was blown surely there would be no sound the


The sub amplifier could be damaged even if you still hear sound. Electronics components don't always blow completly, sometimes it sill works a little bit and then it's harder to find the source of the problem. Make sure your audio source is good and if it is the amp might be damaged.

1 Answer

Unable to receive optimum output. The bass is totally flat !


Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

Dont have accoustimass can i substitute


Bose is specific about how speakers are designed and how the seperate units are connected. It is easy to damage a Bose speaker that is suposed to be connect to a base reflex unit. The base speakers filter out the low frequency that will destroy the small speakers, and speakers that are too large will damage the base unit.
These units can be mixed together only in certain ways, none of which Bose will aporove or honor warranty if you violate the terms of use. Bose systems in the home theater market receivers are specific, and cam damage the amplifiers if you try to mix other speakers with the system.

Loss of bass when both left & right speakers are attached?


I have solved my problem having called a local dealer. They suggested that the bass unit was connected out of phase. I was convinced that my connections were correct having labelled the speaker wires with coloured tape. However I reversed the connections on one channel and surprise, surprise the bass was restored. It's a no cost option so it has t be worth a try.
