What makes a Sub good

What criteria makes a subwoofer good?

this is for my english paper //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

im going to compare other subs to the FI BTL ftw!

im going to compare how efficient it is, but thats all i kno. waht else could i use

How accurately it can reproduce sound, is what makes it good or not. Just like any other speaker.

Think of it like a camera. You can look at a picture and judge how real it appears, and a speaker is the same idea. It should reproduce the sound that was recorded, as the artist intended it.

/Of course if you just want to move a lot of air, $20 and a trip to walmart will buy a good size fan. Lots of people seem to like to make themselves expensive fans out of woofers, but that makes as much sense as putting a loud muffler on a car with a tiny engine, which seems all too common as well.

-cone materials- needs to be strong and stiff, if it bends, sound will be distorted.

Lightweight cones such as polypropylene and aluminum are more efficient but not usually as strong. Heavier materials like paper have good strength but can harder to move.

Composites such as Kevlar or Carbon Fiber lend strength to a lightweight design for the best of both worlds.

-voice coils- Materials, sizes, and design play a big role. Aluminum is lighter and moves better, but copper is a better electrical and heat conductor. Usually a larger winding height and the use of flat wire will dissipate more heat but can add a heavier moving mass sacrificing some efficiency.

-Suspension- Spider geometry and surround design are big here. A loose suspension can be more efficient but have low mechanical power limits. Stiffer suspension is harder to move with low power but can keep the cone controlled with higher power.

**** that helps alot

thanks

I also factor in price...

I can tell you're an EE from that response. It's a question he's going to apply to an English paper, and not one for an engineering class. Not that your input is in anyway wrong, but I thought I'd poke fun at you for how you approached it //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

Maybe now he can take a little engineering to english class and become an English Engineer. lol

i have never paid attention to any of those criterias before.

As long as the teacher doesn't get an inferiority complex by reading about spiders and how they change mechanical Q specs, and Xmax values, lol.
