    DSP/EQ/XO for 2x2226 and 2447/2352

    I have a cinema system with JBL 4648 LF (2x2226) and JBL 2447 driver on 2352 horn, DSP/amp is MiniDSP PWR-DSP3

    Do anyone have reconmended DSP/EQ/XO settings for a combination like this? (Maybe there are presets on DBX/BSS units?)

    Must be downloaded HiQnet for some examples.
    And watch settings for amplifiers CROWN DSI Series - JBL Cinema 56XX models.
    After that, you must copy the settings in the active filter.

    Thanx for input!

    I didn't find any usefull info about cinema speakers within HiQnet but I did the same for DBX DriveWare and there I found some info, at least about the 4648 box used also in 4675C. I guess I could try some of the parameters used on the 2360 but if someone have for 2447/2352 that would be even better

    I've not seen those small horns in the any of the cinema systems. I would look into the installed, portable or tour sound boxes to find a system number with that component load and then chase that in turnings.
    If we knew what the hell we were doing, we wouldn't call it research would we.

    Small horns?

    Most people think the 2352 are rather large Here on top of the 4648 LF box

    Sorry, I meant small by comparison to the 2360 you mentioned (of which I have many) but I don't think the tuning for the 2360 would be what your looking for.

    JBL Cinema does use small horns like the 2342 and 2380 but it seems like they skip right over the series of horns you have.

    They were used quite often in cinemas in Norway and I do prfer them over 2360, 2380 and others I've had. But you are corect that they were not part of a cinema system like i.e. 4670 or 4675

    What settings did you find?

    I am using 0.435 ms delay on my Everest II clone bottom end.

    Please keep us in the loop if you can as you work with your miniDSP units. They are pretty handy little gadgets.
