Equalizers - Honda Prelude Forum

CIT_lude · 12-31-2006, 09:39 PM

I'd like to equalize my bass shakers because they've got huge resonances that make it difficult to find an appropriate gain; in particular, there's a ~45Hz resonance that I'd love to get rid of. From doing a brief bit of research, I wasn't able to find any equalizers centered on bass frequencies, and the regular ones have at best two or three frequencies below 100Hz. Can anyone with experience fill me in on how to proceed here?

look for a parametric eq. they have adjustable frequencies which will give you an at best + or - 15db swing on the exact frequency you need. I know a lot of head units now have this feature built in. good luck and think parametrically

The Audiocontrol DQS is quite flexible and should be able to do what you want. It may cost more than you want to spend on eq'ing some bass shakers though. Its in the 500 range. You could try their epicenter but I'm not sure if its going to do what you want, it may even make things worse.

If your using Zapco amps you will love the DSP-6 sl or the DC reference amps they make. Very flexible but expensive again.

I don't know of any simple/cheap eq's that will do what you want. They may be out there but I cant remember coming across one.

You might look into changing up your mounting a bit. Bass shakers are usually quite sensitive to mounting. Its also free, so maybe best bang for the buck?

Oh yeah I forgot the Audiocontrol DQT if you want to EQ just 2 channels. It does about the same thing as the DQS for a little cheaper. Its still kinda expensive though.

Thanks alot guys - your responses have given me a toehold to start investigating my options. It always helps me to get some initial guidance to focus my research when I enter a totally new field. For the record, here's what the response of these bass shakers looks like:

So you can imagine why this is a problem. I don't need it perfectly linear, but as is things are out of control. Certain frequencies create a great effect, while others are just too powerful and I can't achieve a good balance.

Badahab - I was actually looking for something really cheap as you guessed. I'm thinking in the sub-$50 range

In that range, the "parametric" eq's I've seen (Lanzar, Pyramid, etc.) don't seem to be truly parametric - they still have 4 or 5 set frequencies albeit focused in certain ranges. I think this will still do the trick, even if not perfectly. I don't really see my bass shakers as hi-fidelity speakers

Anyway, thanks a lot for the help; if you have any other suggestions, I'm all ears!

Wow thats quite the curve. I've never been a huge fan of bass shakers but they are kinda cool when you have a couple in a couch hooked up to the LFE channel on your stereo.

If your handy with a soldering iron you might check this out

I believe you could modify it to your needs, and it would be under 50. Maybe more work than you are looking for though. Good luck!

yeah I didn't think he wanted to use a high end eq with a bass shaker. thats why I suggested the so-called parametric eqs available. with a high end moving coil sub it would be a different case. check these out. kind of along the same premise just a full range application.
