Some of you all may think this is a dumb question but here it is any ways.
What if one were to take all the components from a pair L100 Century or 4311 and put them into a bigger cabs, say 5 cu ft, non ported? Or if it would be better, ported.

It would be interesting. The D123 that the woofer is based on was designed for a smaller cabinet, but smaller probably ment at least as large as your speaking of. It was designed with base reflex in mind but by that they ment a decent sized hole or a hole with a shelf on the edge that is toward the woofer.However,that was before they plastered it all up and out an accordion surround on it which is a pretty major mod. I've been going to try somthing like that some day but I haven't even gotten around to procrastinating yet.

I'm now thinking 104H-2 for the midrange rather than fighting LE-5 with the crossover.
It's a "closed-box" woofer. EBP = 48
That makes a closed-box L100t3

Who's got T/S parameters for 123A-1?
BB6P has different than what JBL has published for the 2213s
Edge says 123A-1 is 2212, which is not in the database.
I THINK the forum has been through this before, but I am unable to find it.... :dont-know
It sounds just like the Alpha JBL did but they used a pasive radiator and the Le-20 so it was closer to the 4310 look here:

Actually has some promise as your woofers do better in a larger box. Have fun!!

Thanks, Ron.
Your Vas translates to 212.4 L, i.e., closer to the 124A spec.
Guess I'll hafta rip the insulation out of an L88 and measure a bunch here.
Getting the Vas right is critical to deciding on a box design....
WinISD shows 123A parameters for the 2213s.
Hello ZilchWinISD shows 123A parameters for the 2213s
It should?? They are the same Huh!!! Learn something new every day check out the Tech Sheet for the L88 Plus and the driver interchangability.

Look at this old Pro Note publication. Look at the recomended box.
I have 4 123A-1's Two came out of my L88's and 2 are Ebayed

Zilch,
I have found closed box systems to much more tolerant of tuning. Even if you are off 10 hz one direction or another the resultant product will sound pretty much similiar.
Vented boxes require much more precision to meet the end goal requirements.
Just my 2 cents worth for what its worth!
Ron
