    2268h

    There is the new differential drive 18" 2268H in the SRX 700 line. Maybe someone with better knowledege than I can tell us how it compares to the 2242H.

    For that matter can anyone tell us the differences, such as diaphram size and freq. response, between the older 1 inch drivers 2426, 2 inch drivers like the 2450 and the new 2431H driver in the SRX 700 line.

    I was thinking to use some of these new SRX 700 items in my home theater but am unsure if they will work well.

    2431h:

    We are currently investigating and working with the 2431H in the "Quick and Dirty 4430's" thread, and there's some information gleaned from different sources there.

    http://audioheritage.org/vbulletin/s...ead.php?t=3838

    Use the forum "Search" function to find what's been said about 2450.

    2426 is the versatile 1.75" titanium diaphragm 1" exit workhorse driver.

    They'd (2268H) better be good, because i ordered 2 Srx728s today. Price for
    ASB 6128/ ASB6128v is to expensive in germany (for me).

    I also love to hear opinions from the pros about the 2268h.

    The 2268H is designed to replace the 2241H. 3" dual voice coil. Similar response shape, a bit flatter.

    2242H has a bit flatter response then either of the above.

    I love the 2268H. I have replaced 2241H's in several boxes and have been very happy with the results in every instance. Thee 2268 seems to go a little bit lower to the my ear when used in a box tuned for a 2241. Also, the 2268 can handle a much larger amount of power than the 2241. Also, the 2268 isn't really a traditional dual voice coild design, but a differential drive set-up. This sets up the two voice coils in a push-pull operation between two different gaps. This helps to reduce odd order distortion and it also allows for a smaller field in each gap.

    Cheers,
    Zach

    You'll be more than pleased. Everything I've heard and worked with in the SRX series is stunner.

    A brand new 2268H just went on eBay for $212. I was going to bid, but since it would have been more of a curiosity for me at this stage, (I still have three Sub1500's), I wasn't willing to go quite that high. It would have been fun to play with, though...
