Re: lighten up some subs
Guarentee you that al at us speaker will give you a better 15 to put in that box. Trust me call him I already did and said you will be calling. I would not think of putting a eminence back in that box.
I would not jump so fast.
i remember years (decades) ago when I attempted to do the same thing. A friend of mine had some Peavey W cabinets that had a square magnet stamped frame Eminance woofer in them. I was a big JBL guy at the time and insisted that he would be better off if he put a JBL 2225 in them. The best they had at the time.
So we did just that-put a JBL2225 in one anc then compared it to another one that had the Eminance.
No contest. The Eminance outran the JBL easily. louder-and deeper.
I was stunned. How could that be? I am quite sure in a front loaded design the results would be different. But the HORN (that is the KEY tha tyou seem to be missing here) was designed around that driver.
Just sticking in a "better" driver does not always result in better performance.
I know a number of people who have tried to "improve" on the Keele W design of many years ago with a single 18" driver JBL K151. Since that is a "bass guitar" speaker-people often think that by putting in a "subwoofer" driver the performance will get better. In most cases-not so.
Horns are a very different animal-and very driver specific. I would nto trust ANYBODY whos say they can just stick a "better" driver in a horn and get better performance. Especially a salesperson. Unless I had MEASURED data-no way.
I am not saying that you couldn't find a better driver for the cabinet-there are often a number of different drivers that can be used. But without SPECIFIC knowledge of which driver would work best-you are simply guessing and hoping at best-with NO evidence to back up any claims.
As others have said-swapping drivers in a front loaded box is generally no big deal-but that is not what we are dealing with here.
