I'll admit that often times I don't like the sound of my stereo system. I have all Infinity products. Kappa perfect 7" components in the front, and Kappa 6x9'*. I also have an Infinity basslink. The problem I have is I hate the way the bass dynamics are on my system. I hate it when there is a "resonating" type of bass in music. I like it to have punch to it and that'* about it. I listen to mostly rock, alternative, and some metal/rap, but for the most part I like bass that hits hard, not vibrates me to death. Is there anyway to tune it so I don't get all that bass that is steady throughout a lot of songs? Damn, I can't find the words to explain what I'm trying to ask! I guess compare it to an exhaust system, it'd be like "engine drone." I'll give you my settings below:

Bass
Peak 80HZ
Q factor 1.0
Q-extension, ON

MidRange
Peak 1KHZ
Q factor 2.0

Treble
Peak 15KHZ
Q factor 1.0

Front high pass filter
100 HZ

Rear Filter
None

Subwoofer
Low Pass Filter: 80 HZ

I, too , would interested in hearing how people deal with this. What you are asking for is "tight" bass.

You have a great sound system for a 20X20 room. Unfortunately, you have it in a car. There is not enough "room" for high powered low bass in cars. An 80hz acoustic wavelength is about 14 feet. That won't fit in your car. To oversimplify, it "folds"and puts energy in different (higher) frequencies. If your low pass is at 80hz, your subwoofer is generating signal at even lower frequencies which are really slopping up the sound.

Again, I would be interested in how everybody deals with this. You probably notice it'* not as bad with the windows open, because the low frequency signals aren't trapped. Your car acts like a ducted port speaker.

Basically you have tradeoffs with the bass. If you want tighter bass you can't go so low in frequency. But a 125hz signal just isn't big enough to give you a hard punch in the chest. Although if you have an eq, you could add some gain at that frequency.

All i used to tell people was to not get caught up in the numbers game (hz). Only go as low as sounds good to you, regardless of the hz. 125hz is about as low as you can go without resonances stepping in, but what follows below that becomes your personal choice. Trading off depth with resonance.

One issue I have is when bass beats are off of my exhaust pulses. This is an issue with me because of the shear volume of my exhaust setup.

Can you put a high-pass @ 80hz on your rear speakers?

Have you tried changing the phase of your sub 180* from where it is? It might be fighting the 6x9'* if they're not aligned due to distance or wiring.

Is there any EQ on your sub that can be on or off?

I've tried changing the EQ settings for the regular speakers and it doesn't make that a difference. I don't get the annoying bass with the basslink turned off though. The speakers have the tight punchy bass, but there'* very LITTLE of it, that'* why I got a sub. I'll have to checkout the basslink'* settings sometime. There might be a highpass **** on it, but I think it only has the low-pass. I need a high pass and low pass filter so I can get a range of frequencies on it. I think that'd help. No?

What sub do you have what type of enclosure is it in and what direction do you have it firing

I'm running this little guy. infinity basslink. it'* self-powered with one 8 or 10" subwoofer. I don't remember which it is. It also has a rear radiator to promote better bass response.


here'* a link to the basslink for more specs on cardomain

Switch the sub to 50 Hz, it will only pick up the harder hitting bass, and not the resonance. Thats what I had to do in my car when I had 2 15s and listened to rock, because the bass guitar was coming in louder than the singer, lol.

I would try placing it against the back seat and have it face the trunk I know several people have had good results from positioning the sub this way.

Even with it firing from both sides? It has the woofer on one side, and the passive radiator on the other side.

No one mentioned the gain setting (if the bass link comes with one). I assume it does since it has the RCA inputs. Try lowering the Gain setting, or resetting it to your HU'* output. Another thing you might want to consider is to dynomatt the trunk area to eliminate the rattles and resonance that transfers to your body panels. That will tighten it up a bit as well, but Dynomat make your pockets a bit on the light side. Another alternative to Dynomat is fatmat which is almost just as good.
