I have been given a pair of Gauss 4883xr's, freshly reconed. I am a novice in the world of IB, but have been doing some reading. My question is whether these speakers would be usable in an IB type installation. With their pleated surrounds and low Xmax i know that they are not perfect. My other option would be to go the sonotube routes. I would appreciate the thoughts of the borg. Thanks.

The driver design isn't compatible with down/up firing orientation. That eliminates a tube sub
Those drivers are designed to be used in a ported box or in a horn loaded bass box. Put them in an IB and you'll have paper weights after the first bass transient.
If you want an IB sell them and buy something appropriate to the task.

It doesn't preclude the tube woofer with box at bottom, ie. front facing driver, ala el pipo version #1. Thanks for your optimism.

I'm paid to be pragmatic not optimistic.

I think Paragon would have been much happier lied to, with worthless drivers to follow. You should have posted, "just make sure you use Monsters Cables and they will work great!!!" Apparently he's not interested in reality. LOL, I would listen to Thomas man, if he said it won't work, it won't.

Lied to? No thanks, but pragmatism with limited perspective is not pragmatism. Clearly there are many sonotube type configurations that use vertically mounted drivers, so this does not "eliminate" a tube sub for this driver. I admitted to my IB ignorance and am glad to me enlightened. It's just that some seem to take more pleasure in elimination than enlightenment.

No good deed goes unpunished......I was trying to keep you from destroying your freshly reconed drivers.
Since you missed this from my first post, I'll try again.
NOT ALL DRIVERS ARE SUITABLE FOR DOWNFIRING INSTALLATIONS.
There are formulas for determining whether or not a driver is suitable for down firing. I'm reasonably certain you'll find your drivers fail that criteria (5% or > sag due to the weight of the cone). I've yet to see an accordion surround driver that could be used in a downfiring installation.

As stated now, twice, not all sono tube subs use a horizontally suspended woofer. The original El Pipeo by Sr. Pass in it's original configuration uses multiple drivers/tube, mounted in a cube from which the tube extends. That was my point. I was curious as to whether this t/l loading was appropriate to these drivers. I understand, and now moreso, that the accordian type surrounds don't want to lie on their backs. I do understand also with your help that the Xmax (I'm assumeing ((gulp)) that that is the critical spec along with compliance) of these drivers does not match up well with IB loading. These drivers are traditionally used in ported or sealed cabs, I was trying to see if they would work in other apps. Perhaps best to sell and move to more IB'able motors.

A little googling finds a recommended alignment for each driver is a 6.0cuft ported box tuned to 42hz. So your driver is a woofer not a subwoofer

El Pipo was a transmission line enclosure, not a sonosub. Of course that doesn't mean a sonosub can't be horizontal, it just defeats the purpose of doing a sonosub. Sonosubs are generally down firing ported enclosures. A transmission line is much different and IMO better. |
