Is there a difference between square subwoofers and circular ones?

Asked by Jeremycw1 (1370points) February 2nd, 2011

I was just wondering why some car subwoofers are square and some are round… is there an advantage in either one?

There is no advantage to either, except appearance.

The obvious difference:
<> one is square
<> one is circular

There is no difference in sound except you get a better frequency range with round. And its not by much. But apperance is really the only difference.

The cylindrical ones, like Bazooka bass tubes, can be mounted in more locations. I used to have a pair of 8” Bazookas dropped behind the front seats in my old Integra. Boxes would not have fit.

@IchtheosaurusRex got me thinking your question is about boxes. . . is it about the shape of the box, or the actual sub . . . like the square kicker solobaric?

I would imagine that square has more surface area which make a square 12” more effective than a round 12” sub. I am no expert in any way, but I can tell you that I’ve heard many systems, and the only one that created such a resonance that it was actually difficult for me to breath b/c I could feel the pressure in my chest (WOW!) was the Kicker Solobaric.

@mrrich724 , it’s more about the total volume of the enclosure and the design of the baffle. Almost anything you put in a car will be a ported enclosure, and the way the enclosure is tuned determines how much kick you get out of it and how much distortion you get. All ported speakers have some drawbacks compared to a sealed design, but you get more sound out of a small enclosure that way. The driver element has a lot to do with it, too. As a rule, you want something with a heavy alnico or neodymium magnet as opposed to the ceramic magnets common in cheap speakers.

The amplifier is very important, too. It’s hard to make a high-power amplifier that can be powered by 12VDC that can drive a low-impedance load without instability. If you buy a powered speaker, the engineers will have designed the system to avoid those problems, but if you’re a DIY guy, don’t skimp on the amplifier. A good 100W amp will give you better results than a crappy 400W one.

Yeah I have a little 12” 350W sub, It would be nothing without the enclosure. I think acoustics have a big effect on things. But thanks for giving me your opinions, I do agree that the only significant difference is appearance. I think the square ones look kinda neat, but I am going to stick to the round subs.
