Cool, I still can't answer your question, but I didn't know you could do this as an 18.  I can tell you that with a Dayton Audio SA230 it will drive the 15" version with plenty of headroom, but that still doesn't answer your question.  Can't imagine what it sounds like with an 18, as it's pretty stout with a 15 for sure.

mach-1, you can probably just look at the efficiency of the driver you are using as compared to the drivers you are wanting to compare against. The numbers should be relatively close.

 

for example:

 

rss460ho = 93db
rss390ho = 92.8
lab15 = 88.5
 
Hey Jason, the LAB15's are on blowout on PE. I might nab a couple and build a pair of T-60's instead of T-30's. http://www.parts-express.com/eminence-lab-15-4-15-pro-audio-subwoofer-speaker-4-ohm--299-391

You will need the 6 Ohm version, not the 4.

Driver sensitivity means very little in these horn loaded subwoofers, using this method will not give an accurate measurement.

Doesn't that depend on the amp? Why would a 4 Ohm driver not work?

You are wrong my friend. Driver sensitivity always matters.

 

Sorry to disagree...

Edit: messed up the quote a bit but refer to post #17

 

Nothing to be sorry about, let me explain why your theory is wrong.

 

Driver sensitivity means very little, frequency response will vary wildly from driver to driver within T/S parameter range of the design.

 

Throw one in the mix that is pretty far out of T/S range and your frequency response will not even be in the same ballpark.

 

This is why comparing by sensitivity alone will not be accurate.
