2214H tech sheet?

so. attempting to (mis)interpret this data, based on my rudimentary understanding of acoustics and physics (and almost total unfamiliarity with T/S parameters).

• both speakers have the same flux density, same cone size, almost identical coil resistance, identical electrical and total Q factors (dampening?)

• the 128H has somewhat longer excursion, and a slightly lower resonance frequency, yet a lower moving mass (these last two seem contradictory without other data). the longer excursion means it can move somewhat more air. lower mechanical Q means (I think) it dampens out faster.

• the 2214H can handle much higher power, has twice the inductance voice coil (likely more turns of a heavier gauge, which also accounts for the higher mass?), and somewhat higher efficiency.

I think the sum total of all this is that the 128H(-1) is likely a little better woofer for very low frequencies, but the 2214H's increased power handling means it likely can play LOUDER. and, they are close enough that you can probably substitute the 2214h for a 128H and not miss much, although the doubled mH inductance may require the crossover to be tweaked some.

Your thoughts seem to go to application in the end. The 2214H works better in a larger box and is a little more sensitive. The 128H works where you may need a smaller box. The cone profile is quite different for each. I have not seen a response curve for the 2214 but the upper end of response range is likely quite different from the 128H. If you are comparing the two models for similar applications I think upper end is where the work will be to get similar results.

Yep, I have been down Bean Creek. Not for a while, though. Very nice area coming down into the town.

my interest is purely academic at the present. I have a pair of 2214H that will be going back into my pair of L100T as soon as I get them back.

Is there any relationship between the 2214 and the woofer used in the Urei 809? The reason I ask is because the depth of the frame seems a little unusual for a 12" driver.

I would hazared to quess they are the same beast. Think of a coaxial 4425. The basket and cone sure look the same. They used an E145 frame for the 15" driver so it's no to far fetched of an idea.

The 2214H has a heavier, deeper cone than the 128H although both seem to have the same motor structure. Think of them as cousins rather than brothers.

I've built quite a few systems with both drivers. I prefer the 128H because it works so well in 1.6 cu feet of air. I've made several systems with dual 2214H drivers. Having two gets you a lower F3 and tremendous output. Not a really deep subwoofer but it moves a lot of air.

The L100T has what can best be described as a non-flat response due to the very large enclosure relative to the 4425. You get deeper bass but it's not as clean as it could be. I prefer the sound of the 2214H in a smaller enclosure and let the room boundaries bring up the bottom end.
