I'm looking at buying a cheap set of 2800s as auxiliary cabinets - pull the original drivers, seal the ports, and use the boxes to house the 2123s ... Box dimensions are 22.5 x 11 x 9.5 (mini-towers) but I can lay them on their side. Thats bigger than the 2121 midbass dogboxes in a 4345
(15.5 x 11 x 6), but not horribly so ...

Again - it does sound like they'd work better in the corners as quasi 4344 updates for my 4320s than as woofers for my center speaker.

Hi Heather,

Once you get your 2123 midrangers you may want to play around with them.

- ie ; You may decide to try to make them work as drivers for a center channel .

- So; apart from the fact that the magnets are unshielded, there's another issue. That is , they are pretty "light" in the lower midrange area below 300 hz. I use these in some custom designed SR enclosures and they do require EQ below 300 hz to make them usable for even just a "balanced" voice sound .

- I've prepared a PowerPoint pic of some comparitive FR studies for various JBL 10 inchers. Unfortunately, the official "public" FR study for the 2123 is pretty optimistic / whereas the 251J and 2122H will be closer to the truth .
It would be nice to see a CLIO workup on the 2123 / measured close in / housed in a larger enclosure , such as .75 cu' or so .

- If you are going to attempt to make them work ( the 2123 ) then you'll need to get very creative in the design of the lowpass section for any crossover you buildup. I've included one creative solution ( designed by GT I assume ) for a driver that in balance, has a lot more lower mid than the 2123h. I included the 2122H for the sake of more comparisons.
