    I wonder where they got this idea from?

    http://www.asparaacoustics.co.uk/

    It seems like I've seen this before but I just can't put my finger on it.

    Haven't heard them, but I have a design concern. Anyone with kids should think twice about any heavy piece of furniture that stands on three legs.
    Out.

    Zilch, choose the left one.
    It's because form follows function, look at the throat.

    Sure looks like that series, doesn't it?

    I can't imagine any of the patterns being "right" for the application.

    The horns I'm showing are 70° x 70°.

    Never tried "pushing" 2450 HF, but from experience with 2452H-SL, that might work with SL diaphragm.

    Earl K's done it, I think, with acceptable results....

    Kinda funny.

    Electro-Voice was mounting their horns and tweeters vertically decades ago.

    HF

    An Interesting "oldie" thread that arises from the deep.

    I think this thread predates JBL's Array 1400 ?? which was a real departure for JBL I must say.



    I suppose Zilch was referring to me using 2450SL diaphragms all the way up into the HF // but I really don't remember listening to any of my horns vertically arrayed ( as seen in the first pic ) as far back as 2006 ( mind you my memory is definitely fading these days ).

    OTOH, I am currently listening to a QSC 152i horn ( actually an NLA clone made by PRV ) situated on it's vertical axis.
    I've been trying out a range of smaller format drivers to see if any might supplant my aging Altec 288-8K's ( thinking of future down-sizing ) .

    ( & Somewhat ) as expected the results are very good ( from an imaging and response perspective ).

    Here's another QSC 152i clone ( oemed for B52 ) and available from Parts Express ( until stock is gone ).

    These waveguides/horns are truly the bargain of the century ( IMHO ) .

    Featuring:
    - decent loading to just about 1K
    - sport, great polars!
    - sized correctly to give smooth FR with a minimum of pass band ripple ( negating the need of LCR notch filters )
    - responding well to a simple 3-pole network ( with most drivers )


    For the DIYer using 15's;

    This horn with the Lansing co. driver of your choice ( Altec or JBL ) oriented in the horizontal ( over a 15" ) will give a lifetime of listening pleasure.

    Here's one superb DIY example ( retrofitted into JBL L45 Flare cabinets );



    For the DIYer using 14's;

    No pics to show ( still in R&R mode ) but suffice it to say that with ones preferred ( small format ) Lansing driver of choice / with the waveguide oriented vertically atop a JBL le14 this combo will offer a lifetime of good listening ( assuming one appreciates imaging ).




    PS; most of the above pics are clickable hot-links, to the P.E. sale & the others to build threads.
