    2123 vs 2012

    I've started a new 4 way project and I am evaluating the mid bass options. I own a pair of both 2123h and 2012h 10" drivers. I plan to use the 2245 on the low end and cross the 10' over to the 2450H mounted on the 2380A horn. I do not have any experience with the 2012. Any recommendations? The application is Music reproduction in a large living room.

    2012 or 2123 ?

    Hi Dennis

    Interesting dilemma you have. The easy answer is to listen to both in .25 to .5 cu' sealed boxes and choose the one you prefer the sound of. I think you'll find that both present some challenges in crossover design if you are going to pick a point above 800 hz when passively crossing into your 2450 driver.

    I just swapped a 2012h into a .625 cu' box that was holding a 2123h ( previously occupied by a le10h-1 ) . The first thing I had to do was to replace the inline 8 ohm resistor with one of 4 ohms - this is a quick fudge to offer some level matching to my le14 woofer. This necessity is caused by either different AC impedances or different sensitivity(s) within the realized operating range ( 40 hz to 750 hz ).

    Briefly; I have to say I prefer the 2012. It has a little more apparent lower midbass than the 2123 ( below 300 hz ). The lower mid reminded me a bit more of what one gets from a 2202. It's hard to say if it offers any better resolution - I did think it presented a bit more - but that could be wishful thinking . I need to sit with it for some more time . My midbass is paralled with my woofer so some sonic signatures will get averaged-out by the fact that the le14h covers most of the same range.

    Well you know - if you love something - set it free .

    It's now on vacation - gone back to its wolf pack of le10s to hang out for a while .

    Hey, Earl...

    You got me. And, so did the syntax... So, are you comparing to the 2123H, or the LE10H-1...? Me thinks it's to the 2123H...

    If so, and regardless (how's that for Friday syntax... ), could you provide perspective on the LE10H-1 in that application, or shall we guess it was surpassed by the 2123H (and thus, estwhile...). I've long wondered about stuffing an LE10H into that place.

    That's what I was thinking...



    Thanks!

    Eeeew! No! Don't use LE10H's in place of your 2122H's Bo! What is wrong with your 2122H's?

    Have no fear, friend. Not a chance of me doing ANYTHING to the 4345's... Ever.

    Just curious, being a big fan of the 4313B's , what the LE10H sounds like crammed in that little doghouse? <wagging pooch icon inserted here>

    Yes, the comparison is; 2123h to 2012h

    Oh Lord - Syntax

    You know , I have parts of my brain that are just too multicultural - and they've just never properly learned to speak even one language . How many generations does this take ?

    Anyways, I like the le10 woofs as midbass devices. LOUD is 90 db and my home system stuff is just never used that way. I played Hendrix in bands ( decades ago ) so I've put in my time for LOUD ( good thing my amps were usually aimed at others ).

    Bo ; try it and listen to it - just don't try to match it up with some big thing like your 2245(s). Afterall, it is a fairly low efficiency transducer.

    Wolf Packs

    Hi Giskard

    My cache of multiple le10 (a)(h-1) ( & a single Jolson ) were accumulated for K2 inspired mini 10" versions. Then I collected le14 (a & h ) for essentially the same function. Now they all have to learn to play nice together since I presently use 1 of each in my quasi MTM setup . Long term plans for the whole lot aren't determined - likely project speakers as gifts for the rest of the family.

    What are your plans for the pack ?

    Re: Wolf Packs

    I'm not sure...
    Maybe L96/4313B hybrids in 5.1 surround?
    Maybe just throw them all in the trashcan and uncomplicate my life?
