    excuse my ignorance on sub matters but what is a THX input? does this avoid addition 80 hz filtering?

    Mr Beekeeper,

    You've been around this forum for a while now so surely you must have learned something in that time ;)

    What I know of it bypasses the subwoofers crossover and is set at reference level.

    [edit] Correction- I know the M&K subs have a THX switch, but not a THX input, but it does the above when flicked.

    Clearly there has been a duplicate membership permitted on this forum.

    Mr Beekeeper
    As our original The Beekeeper would no doubt tell you on the Kef at least the THX "feature" fixes the crossover at a static 80hz, he would also most likely add that as he recalls there was some sort of fixed gain output applied, but he may well of remembered incorrectly about that bit.
    He would however no doubt add that these "features" are not necessarily very helpful.

    Steven.

    i may have been a little miss leading i ment to say a thx switch but one of the L R inputs is usually labeled thx and thats the one you use if you use the thx switch.

    it by passes the cross over in the sub amp and uses the cross over in the processor which is set to 80hz.

    dont know if all thx subs have this but would think they do,that was the reason behind my question.

    A THX switch is not needed. The HGS-18 allows crossover to be performed by the sub itself or bypassed allowing your amp/processor to do the neccesary. In fact, you should be doing your crossover on your amp/processor anyway.
    A THX "crossover" is more valuable and usable on a processor like the MC12 for example. This allows a straight 80Hz crossover or a "THX 80Hz Crossover", with the later offering THX roll off characteristics.

    A THX setting on the sub offers no value. On the tale end of the chain, 80Hz is 80Hz.

    The HGS-18 is one of only a handful of subs that have passed THX Ultra 2 Spec and the fact that it has passed without a dedicated "THX" input or switch should explain a lot.

    Unlike many, the HGS-18 does however offer Balanced inputs (as well as the normal RCA type) which is much more important.

    Hope this helps :)
