Need help with driver swap! Win ISD Graph Included

I was thinking about swapping a Eminence 3015 into a PF-115 so I modeled the cabinet. I dont really know what im looking at so I thought I would see what you guys thought. I set the tuning to 50HZ but cant seem to get decent response down to 40HZ, this looks pretty lacking to me, but I dont really know. Would this be a waste in this cabinet? Do you have other driver suggestions for a small cabinet to push around 300w at 8 ohm?

 

This is the HE and the internal volume measures 2.47ft^3 after accounting for the displacement of the Driver, Tweeter, Crossover and support member.

Yes this is ported. The green is the ported version, the blue is the closed version.


I found another driver, the 15N630 that seems to work better in this box, it gets me to 53.8HZ at -3db, but i cant find much info about it online. Not many people seem to use it in bass cabs. Pink is the 15N630 and the Green is the 3015

 

The response looks pretty similar, with the 3015 being flatter and the 15N having more of an upper mid hump.
3015 is red, 15N630 is Black




Does anyone know where i can find the specs for the stock speaker? I would like to model what i currently have to see what the difference is.

 

Exactly this. I was hoping to find something that would just bolt into my existing box and sound good. I have built a Fearful 12/6 in the past and loved that thing, I posted it to GB forums and sold it one day because I was GASing over a 4x10hlf at the time. Found out how much I value portability after a couple months with that 75lb thing and swapped for a pf115 flip top just to give the classic setup a shot.

My goal now is to get close to the fearful sound and portability again without going through the trouble of a new build. I may just have to sell the 115 and build another... anyone got any suggestions for a super portable fantastic speaker like the 12/6? Any good loud portable 2x10's or 1x15's?

 

I actually dont know what a "Good" response graph should look like. Do you have any examples? Would it be worth trying or is it just going to give me mediocre results.

 

Green is with the port 25% Shorter
Blue is original

 

I just modeled this with a 4ft^3 box... Looks like I might be dusting off my table saw again.

Green is the PF115 with 25% shorter ports
Pink is the custom box with the same driver.

My total width is limited to 21.5" [20" internal]
My total depth is limited to 17" [15.5" internal]
This means my total height is going to have to be somewhere around 25" [23.5" internal] depending on how crazy I get with bracing.

That doesn't seem too huge.

Are there other drivers I should consider besides the 3015? I really like lighter drivers.


Is the difference between these two graphs worth the trouble of a new build?
