    Altec Lansing 3127 woofer in hifi?

    Hi,
    I may be able to get four Altec Lansing 3127 woofers at a good price.
    Will it be possible to use them in a good 3 way HIFI setup do you think?
    I am not interrested in a seperate subwoofer solution, but i looks like it is what Lansing themself used them for.
    I do not need to use two units in each cabinet, even i got four units, but it could be interresting to understand if these units are worth buying in connection with hifi.

    Any suggestion?, i do know there are some threads about the 3127, but just wanted to see if there was any added diy info to get.

    I'm confident they won't do the job that you want them to ( ie; anchoring the bottom end of a 3-way HiFi box).

    The 3127 is a mid-bass driver with a highish Fs ( 50Hz ) and a very high EBP ( of almost 200hz ) .
    - HiFi woofers should be in the neighbourhood of 30hz ( for Fs ) and less than 90 for the EBP ( Energy Bandwidth Product ) .

    Try for yourself to create a meaningful box alignment within WinISD and you'll see what I mean.



    PS; They could still be useful to you if you used them with subs ( in an H.T. setup ) with a small horn and driver ( over the 3127 ).

    Excellent midrange. Not as good as 414 though.

    Build a pair of MTM inspired by JBL K2, http://www.audioheritage.org/html/profiles/jbl/k2.htm
