bose acoustimass 10 serie II

[Daniel Barros Contente]

You know the speakers bose acoustimass 10 serie II my uncle has these speakers and I went to help him set up a new receiver (denon AVR X3100w) he bought but I found it strange because in the manual the boxes say the following:

"Setting your Dolby Digital (AC-3) receiver Your Acoustimass 10 Series II speakers are compatible with the output from Dolby Digital (AC-3) receivers. Turn the subwoofer OFF, but turn the LFE (low frequency effects) ON, if available, set the crossover frequency to 200Hz. . "

Speaker Setting at receiver Left and Right Front Large

Center Large

Left and Right Surround Large

LFE (low frequency effects) ON

Subwoofer OFF

Crossover frequency 200Hz

But it has a klipsch active sub how should I configure the receiver of it ??
I must for the boxes in Large and full band leave the subwoofer on (since it has the sub active of klipsch) and by cutting the sub in 200hz?!?!

Thanks for the interesting puzzle. Bose Speakers systems don't follow conventional setup procedures as they use their Sub to filter the frequencies going to their little Cube Speakers, as their Sub is passive (no amplifier built in) and it uses the amplifier in your receiver to drive the Sub. So you'll need to experiment if you want to use the Klipsh Sub (What model is it?).

I'd be tempted to first hook it up as per the Bose instructions and leave the Klipsh Sub disconnected. Then listen to them with a good source (CD, Blu Ray, FLAC, etc.).

Then I'd direct wire the little Cube Speakers to the Denon with the Klipsh Sub connected by an RCA type cable. Try to position the Sub near the center Cube Speaker. I'd set all the Cube Speakers to small and crossover at 200 Hz. Feed the LFE signal to the Klipsh. (This leaves the Bose Sub out of the picture.) Then run Audyssey on the Denon and see how it sounds with the same source. Which do you like better?

If you are looking to to try both Subs. I'd try to set it up as per the Bose instructions but turn the Subwoofer on and direct the LFE to the Klipsch.

These setting may need to be tweaked once we know the Sub model and it's capabilities.

This should be a fun experiment.

Do not connect those little cubes directly to the receiver. You will blow them they are fragile.

This is the frequency response of a Bose Acoustimass system.

As you can see the small speakers are rolled off at 500 Hz.

The bass module starts to roll off about 70 Hz and 200 Hz. So there is a frequency gap.

Now the bass module is a coupled cavity design. When designing these speakers you have a choice of high bandwidth and high Q, which does not sound good with a sloppy bass, or narrow bandwidth and low Q, which has a tight bass. You can't have both. Bose chose the former.

So you can see why we pour scorn on Bose.

So what you need to do is connect the system as described by Bose, and set the whole Bose system to small. Set your Klipsch sub to the sub out/LFE output of the receiver and set the crossover at 100 Hz.

That will make the best of a bad job.

If you don't like what you hear then ditch the Bose.

this is the review where the measurement came from:

I suggest to OP to read it, then quickly list his bose speakers on ebay. use profits to buy better speakers.

I know they are bad speakers but my uncle does not want to change them for now. What I thought I'd do there and use both sub for it to stay with a 5.2 system! I would like to know a setup tip that I thought of for all the large boxes (which is recommended in the Bose manual) and put the sub active with crossover at 80Hz or 120Hz (the Bose recommends leaving the LFE OFF and crossover on 200HZ) for now I left in small all the boxes with cut in 200Hz the sub on and LFE with crossover and m200HZ but I found the grave very heavy and present of the to perceive from where comes the grave!

My pleasure, but I'm Brazilian. Grave = bass sound

Grave means low, low pitched or sonorous in Spanish. Although the exact translation of bass in Spanish is bajo.

I don't know Portuguese. However on look up I find the translation is baixo. So there must be a similarity with Spanish in having two words for bass. In Italian it is basso.

Yes i´m Brazilian in portugues grave is the same as bass. I'm sorry, but my English is not very good.

Is Google correct, that baixo is also bass in Portuguese?

 

[Daniel Barros Contente]

In case of sound yes baixo, grave is the same ass bass low sound, but baixo It can also be related to size as a low person.

Ok, here's the issue, since you must use very high crossover to keep these tiny boze speakers from damaging, 200hz grave is easily to tell for humans where it's coming from.
In your uncle situation only way to partially address it to place sub in the front, not far from bose speakers.

 

[Daniel Barros Contente]

So what he and I wanted was a 5.2 system, how do I make the Bose subwoofer and klipsch get bass without getting too heavy like this at 200HZ!
If I for every speaker in large LFE in On with crossover around 80Hz to 120Hz would I lie the bass on the Bose subwoofer or would it be redirected to the klipsch ?? In other words I would have to configure my system to have bass on every speaker and would have one more subwoofer. How do I get this setting on the Denon AVR 3100W ??

You will not get anything close to a perfect result here. The only way if doing this, is like I outlined.

You need to connect all the receiver speaker outs to the bass module. Connect all the small Bose speakers to the Bass module.

Now on the receiver set all the speakers to small.

Now connect the Klipsch sub to the Sub/LFE out of the receiver.

Any other connections will cause damage fast.

Now set the receiver crossover to 100 Hz. If you go any higher this will give you far too much bandpass gain and muddy bass. This will give you one octave between the Klipsch and the bass module. This is not enough, and there will be some bandpass gain to muddy things up.

Set the crossover on the sub to 100 Hz also. This is going to double up the crossovers, but in this case it will reduce bandpass gain and make things cleaner.

Now run Audyssey to set the sub level and distances.

Place the Bose bass module and the Klipsch sub near one of the front speakers.

Place anything with the word bose into a grave.
Sorry couldn't resist. Lol

It really does blow my mind that Bose is such a popular name. I get that their marketing strategy has a lot to do with it, but a few internet searches can straighten that out pretty fast. I absolutely do my homework when it comes to spending that kind of money.

The Bose bass module is not a subwoofer.

Bose is to subwoofer, as Prius is to formula 1.

Hello, I configured all the boxes in small subwoofer yes
Crossover LFE at 200hz !!
If I lower the LFE crossover to 150hz or 80hz, can I damage the speakers?!?
