would it be appropriate to say; the bigger the woofer the bigger and boomier the bass? but i wanna compare the klipsch promedia GMX-A-2.1 speakers and the Cyber acoustics CA-3552's.

Given the commercial nature of the designs, it would probably work the other way around where the smaller the woofer, the boomier the sound.

boomier and bigger are very subjective words. Are you trying to avoid boomy bloated bass, or are you looking for a subwoofer that can drop low notes controllably?

Both of those criteria would be more comfortably met with a larger woofer though both can be abused and are not mutually exclusive of each other (larger woofer vs. criteria.)

Their are subwoofers with big drivers and/or big enclosures that are boomy, and also some that are not boomy.
Their are subwoofers with small drivers and/or small enclosures that are boomy, and also some that are not boomy.

So basically you can't make that generalisation. It all depends on design type, cabinet bracing, driver quality and how well it's matched to the cabinet, amplifer, requested SPL, frequency response, F3 response, user preference for bass, crossover settings etc etc.

I've used subs from PC systems, budget subs, mid range subs and upper range subs. Not uber range yet :-)

Like Necros said, it's entirely based on the setup the driver is going into, not the driver's cone size. By far the largest influence is the size and tuning of the enclosure, with the crossover setting and system's midbass capability coming in a close second. I've used low budget subs, mid level subs, and supersubs in a variety of alignments, you can make even the best sub sound like crap in a bad install. Are you looking for sub recommendations or just a technical explanation on how the mass of a woofer's cone relates to its transient response?

Hi sony_man, usually the word 'boomy' has negative connotation in audio bassworld - in that a boomy woofer sounds strong on a certain frequency i.e. a bass peak. In high freq terms that would be like a sharp biting treble vs extended smooth one.

Correct me if i'm wrong here, if you were asking whether woofer size correlates with better sounding bass then yes, in a sense that 15" woofer will produce low notes better than 4" woofer. However, there are numerous factors that determine bass quality other than size - a 10" woofer in a well designed enclosure will easily outperform 12" one inside a lousy box.

Off topic but for a good reading what those people really saying ...

The magic is in servo controlled subs.

But that increases the price quite a bit.

Servo design can cause problems too, and is not necassarily better.. in some cases a stuttering sound- some HGS suffered from audible noise whilst in idle due to the servo. Also more things to fail..and some badly designed servo subs (ie Yamaha)

There are some good servo subs though

I have a question about my subwoofer, my subwoofer is about a year old and it performs pretty good with bass but when the bass goes up it makes this sound that i dont like. it gives this "bowm" sound. Yes it is a cheap subwoofer and speakers i use a gigaware system that costed me 50 dollars.

 

Is there a way to fix this or is it time for an upgrade?

That might be due to where the subwoofer is placed. Speakers interact with the room.

Try moving it to a few different places and see if that helps.

Its about a foot from where im sitting at. I use it as a desktop speaker. Its that when raise the volume and when the bass goes high it feels like it doesnt give a good sound even though when the bass goes low it sounds pretty fine. Sorry if i cant explain it well.

It sounds like the sub is crossed over too high.
