PA speakers for midbass?

[Clipped]

anyone ever think about using PA speakers for midbass?

I ran across these really cool PA speakers, 12" with 4" coil, REALLY wide magnet... they look pretty mean. $50 each

[tinitus]

Yeah, in high efficient a 4way but 3way is possible ... depends on driver ... more information is needed

ups, sorry didnt see its "car audio"

Why do people spend so much time and effort to listen to the BEP's in a phone box?

I am using 2 X 12" Selenium PA speakers for Sub bass.........though

[Clipped]

workhorse, how does the output compare to higher excursion subs?

as far as the brand, they were in the eminence display case, there wasnt a saleperson there so couldnt ask, maybei'll go back tomorrow and try again...the spider was pretty wide so im guessing this isnt just a midrange speaker, but a midbass.


whats a BEP?

and whats beamwidth?

BEP = Black Eyed Peas, ie obnoxious noise with a beat.

[Clipped]

no black eyed peas here....no siree

The trouble with PA speakers is their high efficiency would make it difficult to balance with the other speakers in the system unless of course you are going to run it active.
Using PA speakers as subs wouldn't work too well normally as they generally don't go very low, often with a Fs of around 60 - 80hz and are usually only have short travel.....

Cabin gain would bring that up markedly in most vehicles and most car subs I've seen have quite a small box tuned high. Xmax shouldn't be an issue, as many are 5mm.

Car subs typically are double that amount of excursion and even a 10in car sub can have an Fs of around 20-25hz which is far better than 60-80hz even with the gain which applies equally to both it only makes the car sub better still....
