Bose acousimass 10 bass box not working

The output voltage on the secondary appears to be tapped at 22 and 16 VAC.

your acoustimas requires you to connect all speakers outputs to it first then to the speakers.

What is your crossover setting set at?
If it is set at 40 HZ, this would explain weak bass; as that Bose system sends ~120HZ down to the sub.

I reccomend checking the crossover setting to 120 or 100; with all speakers to small.

You may need to increase the db setting on your sub as well......

Good Luck.

your bass box woofer driver is bad. Need to replaced the driver board. There no easy out.

Hello Adam Hi, it looks like your main IC amplifier inside the main bass box is bad, need to replace that IC. What are your plans, do you want to do the repair or have it service by a tech guy.

this is possible, however not a very good idea.
Bose speakers are designed a little different than other brand speakers, the Equalizer built into the bose system will probably not sound amazing when you hook up your other speakers. Are you looking for more bass? cleaner highs?

if you want more bass, you could try doubling up your subs, if you want cleaner highs you could buy Bose Jewel Cube Speakers (purchased from a Bose Built-Invisible Dealer

A lifestyle 20 system is stereo only. Two channels. Left and right.

If the system doesn't have controls labeled "bass" and "treble" - or if there are no clever presets like "Hall", "Theater", etc., then you'll have to adjust these parameters before the signal reaches the speakers. One way is to purchase a graphic equalizer to hook between the speakers and the signal source. A graphic equalizer a basically a tone control, with the spectrum divided into 10 or more "slices" instead of 2 (bass and treble). Consider the sliders on the left as "bass", and the ones on the right as "treble". If you're using these speakers for a computer, some sound card software has these controls buried beneath a few menus - but sometimes not. The easiest solution is to buy an equalizer and hook it between the signal source and speakers. Bose is typically "audiophile" equipment, and many audiophiles don't want tone controls (thus the extra electronic processing required) to contaminate the signal. Obviously, most systems do need to offer some control to the user, as you've discovered!

If you're saying you hooked the Bose speakers directly to the Yamaha's amp instead of the prescribed way through their own bass module - they're cooked.

You probably can do it as long as the speakers there now are 8 ohm speakers and you must use the bose bass module with the cubes because the crossover is built into the bass module for the cubes to work. If you just wire up the cubes you will mess the cubes up and they want sound right at all. The cubes are no good without their bass module in other words. Hope this helps.
