Bose subwoofer ?

[bullittandy]

I've got a 97 Q and added an Infinity Basslink. Where should i set the crossover on the Basslink, I've got a choice of 50 hertz to 200 hertz. What does the stock system reproduce and in general how much overlap between a subwoofer and a woofer?

[elwesso]

what I like to do is put it somewhere in the middle, turn the bass down on the head unit and that will make the basslink take care of most of the bass.

wait wait . . . you mean like this?



I guess I'm confused...

Go with 200hz. The factory speakers are rarely good below 120hz....you may end up with some layering between 100 and 200hz, but at least you'll know you are hearing everything.

I don't think he was talking about that kind of Bass... unless he is putting an aquarium in his trunk. But, then I don't know what all that talk of Hz would have been.

BTW... some definitions of Bass from the intarweb.

Definitions of bass on the Web:

* the lowest part of the musical range * the lowest part in polyphonic music * an adult male singer with the lowest voice * sea bass: the lean flesh of a saltwater fish of the family Serranidae * freshwater bass: any of various North American freshwater fish with lean flesh (especially of the genus Micropterus) * the lowest adult male singing voice * the member with the lowest range of a family of musical instruments * having or denoting a low vocal or instrumental range; "a deep voice"; "a bass voice is lower than a baritone voice"; "a bass clarinet" * nontechnical name for any of numerous edible marine and freshwater spiny-finned fishes wordnet.princeton.edu/perl/webwn

Actually, 200Hz is probably a little high. I'm sure the Bose system produces smooth response down past 100Hz - it just doesn't have enough power to drive very loud at that frequency - the amps overdrive and you get distortion across the entire frequency band. Installing a subwoofer, and especially the crossover, will help take strain off the Bose system and you'll be able to get higher volume without distortion. The higher you set the crossover, the less power the Bose will have to handle and the louder it will play, but you only want the subwoofer to handle the very lowest, "non-musical" frequencies.

So, setting the crossover too high will make the lowest frequencies sound "boomy" ... too low won't take enough strain off the Bose amps and they won't play as loud as they otherwise could.

If it's not hard to get to after installation, I'd say start at 100Hz and inch it up until you start to hear too much annoying boominess. You want a thump, not a boom.

ooops... I read his original post as having the only options as 50 OR 200 Hz. I wasn't thinking about the range between...

I agree. Start with 100... I still don't think the original speakers are doing much below 120 (at least, not with any appreciable volume), but you are better off starting a little low and working your way up per 96Qowner's recommendation.

Well, okay, so I was wrong.Personally, I'd put aquariums in the headrests.

Return the bass link. I had it and it sucked in the Q's trunk. Get a real sub setup. The Q's trunk is built like a coffin.

This is absolutely true of the trunk in the Q. With the hard metal deck, metal separator between rear seats and trunk, plus the gas tank sitting there... not a whole lot of sound is getting through to the cabin. In fact, unfortunately, the most 'sound pliable' membrane between the trunk and the cabin are the speakers mounted in the rear deck. Thus, you're not only going to get a highly muted version of the sound but may also hear distortion in the speakers in the deck because of it.

Unless you can find an effective way to vent the sub in to the cabin (there are lots of ways to do this, even without using a technically "vented" box) it is unlikely that the sub is going to add significantly to the music you hear.

However... with all that said, it is important to keep in mind that I am talking about pretty small differences in sound based on someone who is specifically listening for such things. For everyday use, and for someone who isn't a real aficionado, you're set up might be just fine.

When I had mine, you could not hear a thing out of it.

I have a JL audio W3 12 and the sound is still minimal.

Thanks for the info, the corssover is variable from 50-200 so I'll set it at 100.

I've already installed it and the Basslink hits EXTREMELY hard. With the gain, crossover and "bassboost" all set at midpoint I can only turn the remote control gain to 1/3 before the bass overwhelms the stock system.

I've read several reviews where switching the "phase" switch and placing the sub correctly greatly adds to the sound quality.

I'm not much of an audiophile but my wife has a 01 Volvo V70 with the top stereo system (which Edmunds rated the third best stock sytem behind the big Lexus and Mercedes) and compared to that my Bose with the Sub sounds awfully nice.

I think that part of a stereo's "sound" is dependent on the time that the listener spends with the stereo. Your brain acts as a filter for the sounds that you hear and so it I think it takes time to "learn" how a particular system should shound.

Think of watching a video recording of birthday party or other group of people, when you watch the recording later on the TV all sounds are recorded and the same volume but when your in the scene your brain filters the extraneous noise.

That may be what I described as "boomy". It sounds like you have enough controls to work with. I'd play with the gain and the bassboost, too.
