Question about Bose 901 EQ1915 Home Equalizer

1 Answer

No bass response out of 901's but 301's are perfect

I have tried two different receivers (pioneer sx-2300) & (Onkyo A-RV401) and cannot get a clear sound or any bass whatsoever on the 901's series iv. I also have a set of 301's that work great except when they are run through the equalizer(distortion kicks in).
Ihave new cables & have tried using different tape monitors,vcr line,...etc I even hired a disc jockey who owns a set to look at them & he can't figure it out either.
HELP PLEASE!
Thank you,

DR Kee

You should check your 901 speakers for phase.
Heres how to do it........ Remove the 901 speaker grill so you are able to see all the drivers cones. Now connect the 901 speaker wires to a 9 volt battery. Now u can check if all the cones would move forward or backward at the same time. Make sure that they all move in the same direction, otherwise you have to reverse the polarity of the driver that dont move with the rest.

Bass frequncy


Hi there,
Although I am not familiar with the Zoom HD 8 Track I am a former sound engineer so may be able to offer some general advice.
Firstly, because the wave pattern of low frequencies is very long, there are a number of things that will greatly effect bass response caused by standing waves.
1) The position of your bass monitors. Ideally these should be low down but not directly on the floor, especially if the flooring is wooden.
2) Try your monitors/speakers at a slightly different angle. Bass can bounce off walls, back towards the sound source and phase out the signal, rather like a noise cancelling system.
3) Try listening to the sound in different areas of the room. You will be amazed at how the sound pressure level will vary, simply by you moving from one position to another.
4) Never put bass tracks exactly at centre, always offset them slighly by a few degrees left or right.
5) Do some of your mixing using headphones, you will not have to worry about standing waves. But remember that things sound very different on speakers in free space.
Strangely, the reason you are getting distortion when you turn things up is probably because your bass is on the verge of over modulation to start with. Really bass is felt, not heard. You could try is to decrease your mid and high frequencies a little. The ratio between high frequencies and low ones will then increase by default and your bass may feel heavier.
What are you mixing?
