    It is an E155, 2240 or 2245, depending on the cone & coil, but who knows what it is or was; it is not a 2241 or 2242, it only has the center vent.

    I know this is an old thread, but can't find too much info about the 2243

    Anyone used this driver? And how do they comapre to i.e. 2242? What is the real difference between them, is 2242 more meant for subwoofer and 2243 midbass or..?

    I'm thinking about useing them for my hometheather but don't know how well suited they are for this.

    Do you have the driver? Can you post pictures? This is kind of a rare driver

    I haven't bought them yet so unfortunately I don't have pictures.

    They are in fact not that rare (at least not here in Norway) since they were used in the quite popular JBL P749.

    I'm a bit confused about pictures I've found of the 2243 since no of them have foam surround, so I'm not sure if this is a correct 2243 but I think so:

    According to the application, since they are used in SR cabinets P749 and P798, I doubt they have a foam surround, my guess is that they are more like a 2241 or 2242, measuring the basket and magnet would sort it out.

    The 2243 has copper wire according to the spec sheet of the P749/798, while the 2241 and 2242 have aluminum wire....

    2240 and 2245 have copper but they don't have this basket


    --------------------------------- edit --------------------------

    Also, the cabinet with two 2243 is rated 1200W AES, while a cabinet with a 2242 will usually be rated at 1200W AES per driver, such as the ASB6128 or ASH6118.

    The 2243 would be a 2242 with a 2240 era cone and VC ???

    It's stated several times that the 2243 share the same basket as 2242 so that a 2243 can be reconed as 2242. The specs for raw speaker says that 2242 can handle 800 watt, vs 700 watt for 2243 so I'm a bit confused as well

    For power ratings one has to be careful as there is some differences in depending on the era.

    Lately we see AES ratings.
    At some point there was "program power"
    Before we saw "pink noise power" and even before "sine wave power".

    As a rule of thumb I consider sine wave and pink noise to be +/- the same, and AES and program being equal and equivalent to twice the sine wave power.

    This is a big can of worms

    That was JBL, now don't get me started on the "RMS power" used by some others.

    I have four of these drivers and they all look the same as the picture you posted. What I have learned are that they indeed share the same basket as 2242. They have a somewhat lower Fs (30Hz compared to 35 for the 2242), a lower power handling (700W compared to 800W for the 2242) and a lower sensability (97dB compared to 98dB for the 2242). My contact at a JBL service center thought that this driver were a complement to the 2242 when smaller boxes were needed but I wouldn't take that as a fact.

    I haven't been able to compare them to a 2242H driver but as far as I'm concerned they sound awsome. Tight, deep and clear. As I've written in another post here on the forum I'm testing 2 of my subs with a 6dB filter at 25Hz. Despite this low cut off, due to the 6dB roll off, the 2243's is forced to produce sound in rather high frequencies and they still sound great. The 6dB roll off means I trade some of the tightness for something that sounds better overall IMO.

    I've paid 1500 to 2500 SEK for mine. If the price is right, go ahead and buy them. I would think they are as good a driver as the 2242H
