You'll have to run the box models and compare, and also verify that the baskets and motors are the same.
I don't think of 2214H as a particularly extended-bass woofer, but maybe....
I'm gonna send an original cone to Gene to see if he can match it up for exactness sake. I might swap the voicecoils. One thing is for sure, the cones are exactly as well as the baskets.
With 125WPC on two of these, I hit 137db at an IASCA contest in 1990.

The baskets for the 2214H and 128H-1 are not the same. The 2214 is quite a bit deeper. Looks like a mini 2245 basket and driver. The 128H-1 will go lower in the same volume. So if you are going to be in say 2-3 cubic ft go with the 128H-1.

Thanks Rob. But I misspoke the model numbers. It's a T120 woofer not 120ti.

That sounds pretty sweet, & along with my current experiments. :thmbsp: I've been running a pair of NS-1000Ms with 12" alnico organ speakers, since one of the stock woofers was blown when I got them. They sound really good with tubes, but I'm going to recone some D130s sometime, they really want a 15". :yes: I have a nice 8" alnico pair (woofers from ESS Tempests) , & was playing the idea in my mind, about going 4-way, with a low-mid & high-mid.
But I'm no crossover guru, lol, so it hasn't gone far yet, besides having to find appropriate boxes. :scratch2: 
The T120 frame and magnet is an EXACT MATCH to a 2214H-1. I've had both side-by-side.
Reconing them as 2214H or 2214H-1 should go without a hitch. That's what I'd do. That woofer did a fantastic job in the 4425 monitors. Should work equally as well in an E-wave setup. http://www.audiokarma.org/forums/showthread.php?t=150939
If you're going 4-way, I'd be inclined to use something OTHER than the Vifa P13 mid. Just too much of a dynamic difference between that and the 2214H. The Vifa is decidedly "overly polite" and "restrained"... to the point of "throwing away the life in the music", IME.
If you want a better 5" or 6" driver... there's LOADS of them out there. Dayton Reference, Eminence Alpha 6, JBL 115A/H, EV VMR, Audax PR170M0... just to name a few.
However... the E-wave setup would be MUCH easier to tune out, and probably would have even better dynamic response and power/off-axis response than the 4-way... for the same (or less) parts cost, I'd MUCH rather have the waveguides on the top end...

Gordon.

hmmm.... so many options
I bought the BE tweets and mids to be replacements for when my kids become teenagers. So I have no problem leaving them be....get it!, BE.
ANYWAYS...there are some L65 cabs for $100 close to me. I could either go that route or the wave guide. Preference? I'm not really into West Coast sound. I like my speakers to be accurate and musical. Ala NS-1000, Dynaco A25s, Carver Amazings. Just looking to make one final set that will have a little extra kick in the low bass, ie 20-25HZ department using what I have. That's why I mentioned the AR TSW-910 woofers.

You're describing E'Wave to a "T". Jack built with 2214Hs and said they were among the best he's made, as I recall.
I like Gordon's PR idea. Build some Econowave towers based on the L150 model. Use a 15" PR like L220 did, though. Gordon'll tell you why.... :thmbsp:
These, maybe?

Interesting that you mention a PR. However I really prefer not to go that route. My experience says a PR isn't better than a port....might mean I just don't have enough experience.
The original boxes for the T120 per speaker is 2.5^3ft with a single 3" x 6.3" port. This is tuned port of 30Hz and a -3db of 48HZ. The open air response gets better with bigger and bigger boxes. But the tuned port goes up in frequency.
And what about midbass distortion? Am I still looking at a 3-way?
