    I run a 15" 2226 below my 2360 w/ 2441 and Radian diaphragm. I cross at 500Hz. Sometimes I move the point up to 600Hz. 24db L/R filtering. I also fitted another set I had, 2445w/ original diaphragm. And also cross at 500-600Hz. But when I switch to an 18" 2240, I may have to cross at 400-500 Hz as I don't think the 2240 can play nice and clean up to 500Hz.

    You mean 2441 with Radian diaphragm in 2360?

    After some testing I find that 2446 do absolutely best crossed at 600hz 24dB/LR with either standard ti or aquas.
    The BMS 4590 can go lower.
    Can be crossed 450hz 24dB/LR in 2360. But that is the absolutely lowest I will recommend running 2360.
    At 400 the horn do not sound good.
    The BMS can go down to 350.


    Actually now I`m testing old 2410 with adapters in the 2360
    Crossed at 1khz.

    No. Just the 2360 for midrange and highs

    Did you try to cross lower?

    I have tested the 2446 in 2360 all the way down to 350hz.
    In hifi the driver is fine with 350 without diaphragm crash.
    BUT it sounds bad!
    The 2446 should be crossed at 600hz or higher is what I find out.

    After testing BMS 4590 and JBL 2410 1" with adapter in the 2360, I ended up on using the 2446 aquaplas and 2405 tweeter.

    This is how the final system looks like.

    2360, 2446 aquas, 2405 alnico tweeter, 3 x 2226 in open baffle.



    Find the BMS driver to be the best if not using tweeter and can be crossed at 450hz after some testing.

    The 2410 1" was also ok, crossed at 1khz and some EQ in the top range. The driver has some ringing under 1500hz, this makes an uncorrect, but cool sound (like growl).

    Only crazy people put 2226 in open baffle
    But it sounds good to me.
    It`s crossed half way. Upper bass crossed at 600.
    The two lower 2226`s crossed under dipole peak.

    Both filters can probably be made a little better, as always

    2220’s and 2360’s are two of my favorite things.

    Nicely done!

    Thanks!

    This is just bringing an idea of making an JBL Open Baffle.
    It works fine down to about 40hz placing the front baffle about 1m from front wall.

    Yes the 2220`s and the 2360`s ar addictive

    It can be done with three 2226s just removing the 10ohm/100w resistor with 2446 drivers.
    Have not tried with the 2410 as the 2226 probably will not sound to good into 1500hz.

    Update.

    2446 playing with original ribbed Ti diaphragms D8R2450.
    When using tweeter crossed 7k don`t find so much advantage using aquaplas.
    It`s just a bit different.

    Aquaplas adds weight to the diaphragm.

    If not using tweeter aquas are best.


    Also now use 2404 as tweeters.


    Must change filter when changed diaphragm from aquas to Ti.
    Freq.response is different.

    Maybe Altec/GPA 288?

    TAD is to expensive...

    Hi,
    (First I'm french speaking)
    I got JBL 2440J and 2441J I have both and i use 2441 it on my 2360. For Hi-FI use the most important thing is the diaphragm you will put in these drivers, forget Ti. Use 2441 Aluminium diaphragm is a must.
    With these drivers 2405 are great tweeters I love it.
    I have Altec 288c also and they are great also but JBL 2441 are easier to find in good shape.

    (Sorry, I Can't put photo)

    Thanks for responding Macsic!

    Yes, the 2441 i read is very good.
    Alu diaphragm, beside beryllium I have not tested.
    Beryllium is to expensive.
    Alu, maybe some day I buy and try.

    But I think the original ribbed TI sound quite good as long as use tweeter from 6-7k.
    Over 7k the TI diaphragm sound really bad with a lot of resonances.

    I have the 2405, and it`s really good!!
    2404 is just a tiny bit better with the 2360, but it`s not by much!


    I will not test the Altec 288 as it needs adapter.
    Adapter makes the already long throat of 2360 even longer...not good.

    But, yes, I read and people tell the 288 is really good driver!!
    And it can be bought new from GPA!

    Hi,
    I did not test Berrylium Diaphragm but If I will want to update, the choice of Berrylium in 2441 is cheaper and better choice than buying a TAD after some reading.
    Anyway go with 2441-40 with your 2360, it's a great match.
    I also try JBL 2395 lens and I prefer the 2360

    Titanium has a hard sound compared to aluminum, the silky sound of aluminum is really obvious. I have original diaphragm titanium and aluminum, I have listened to both in the same configuration with JBL 3105 crossover and believe me the Di aluminum are really better for Hi-Fi use. My Titanium 16ohms diaphragms are for sale
    since ;-)

    For 288c I prefer to use an Altec horns 1005B (very good) and keep the JBL2360 for my 2440 or 41 drivers

    Bye,
