What are the advantages of Bandpass?

Recommended Posts

No im not thinking of building/buying one, but i notice nobody likes em. Whats wrong with them? At one time they seemed like they were the way to go.

Pros:

 

Easy to direct output.

Higher power handling.

Keeps speaker free from debris.

Proper design leads to great low frequency extension.

 

Cons:

 

Usually a large enclosure.

Hides distortion so you can't detect possible damage to your driver.

Overall, very hard on the driver.

Very hard to build, and design.

I dont mean to be rude, but what is the highest level of education that you finished?

It's just what I've heard - I don't know if it is a myth or not.

the bottom line is this: unless you plan to build your own bandpass box and put a ton of hours of design and work into it, do not get one. you especially dont want a pre-fab bandpass box.

Well when I first got into car audio, I got a pre fabbed bandpass for my bazooka subs. (They weren't all that bad actually, bazooka only has a bad rep cause of the tube subs, other than that, bazooka is pretty good) I can tell you, only get a bandpass if you want pure SPL. It ruins any kind of SQ (unless built directly for that sub) but makes almost any kind of driver really loud.

4th order bandpass has a good transient response, power handling, and a lower cutoff frequency.

 

A 6th order bandpass has very nice power handling within its passband, but outside of the passband it's power handling is poor- the driver relies on its suspension under the passband (just like ported)...not too good of a transient response as well...

Thanks for all the responses.

Do you know a web site where i can get instructions on how to construct a proper bandpass enclosure. Im just curious.

Enjoy :)

 

And good luck...if you do decide to build one, let us know how it turns out.
