What frequency range?

[/B] What frequency range should a woofer be rated at,to produce the best bass??

 

[Sir.Byrd]

:yes:

Seems to me that you'd acquire your low/mid/hi freq drivers, study their specs and design the XO based on those numbers. As to the boxes... that's a whole 'nother can of worms.

I,have the mids,and tweeters,also have the new XO,that will perform at 800 hz to 4500 hz. What I'M looking for is some opinions on what freq.range the woofers,will perform at,say from 52HZ-4.5KHZ. And produce great bass.

What's the frequency, Kenneth?

This is a far more complex question than you may suspect. It might help people to give you a better answer if you can define what you mean by the "best" bass. Do you mean the lowest low tones? The clearest, tightest bass, that allows you to distinguish one brand of string bass from another, similar one? Bass that gets loud? Bass that physically "slams" you in your chest, or that rattles your guts and spine, and makes you fear that it will damage your heart? Are you looking to be able to pinpoint exactly where the tympani and the string bass players are, in a large orchestra? Or are you listening to mostly electronic trance music, with deep electronically-produced bass that doesn't actually come from anywhere?

What we hear as "good bass" is also part of the frequency range: how your bass drivers interact with the other (mid and high) drivers will greatly affect how you perceive the resulting sound. Crossover points, slopes, and response characteristics (speed) will all be important here, as well as a few more technical factors.

Also very important is your cabinet: you'll get completely different bass from the same driver, if you listen to it open baffle and in a horn or transmission line cabinet.

In audio, everything is about choices and compromises. Let us know your specific preferences and intended use; what you are aiming for when you say "best" bass, and you will get more helpful answers from people. Otherwise, there are too many possible answers to choose from.

HI,yes I want nice tight bass,clear and not over powering. But yet I still want to be able to hear the string bass,as well as the kettle drum. The woofers are going in a 2.63 cu.ft. (vented) enclosure. This is a DIY,at home project,and all other pieces will be matched as close as possible.

Sounds like your taste might be more toward sealed enclosures. You can always plug the port. What size driver? You should probably download on of the free box design programs (boxplot e.g.) and run some sims on likely candidates. If you decide to go with sealed you will want a Qts of around 0.4. You don't want very high Vas as you are using a not too large box. Just as a guess start with some around 2cu-ft and see how they sim. All else equal of course you want low fs but this interacts with other params and sometimes higher fs still gives lower cutoff. Most rooms probably will give some reinforcement under 50hz.

OK,had mail from Eminence this morning,there tech,e-mailed charts,and graphs,with all specs. OK,it's a 12 inch driver. There rec. for this size enclosure (vented) is,frequency response:52HZ - 4.5KHZ

(QES) .37

(QMS) 7.56

(QTS) .35

Compliance Vol. (VAS) 2.89 cu. ft.

Eminence,also sent suggestions on there line of woofers that match these numbers good.
