    pretty much what I would say. Except you want the FR tilted up a bit from the low bass to the mid-bass to allow for Fletcher-Munson. The 'House Curve'. And then you need to move air, quickly and effortlessly.

    For me I don't see why, on paper at least, a system cannot do that and also deliver delicacy and musicality.

    I wonder if a way of getting a large sense of scale is about moving air, but not just bass, mid bass and mid, hence why some speakers have multiple bass and mid drivers. However, I suspect that the price you pay for that is speaker efficiency, which is also something that helps with delivering a big sound. I guess there are a few ways to skin the cat, each with compromises.

    Not really. The bigger you get and the more drivers you have, the more efficient you get. As long as you keep the drivers light.

    Fun tread, same tought...
    IMO big drivers Low frequency you do not listen to it whit ears they hit U on tummy

    Big driver bas reflex = slow small drivers long throw= fast (EG gogle up Ophidian)
    Small drivers no low frequency
    Das drum sound like Pum Pum or better Tum Tum ?

    Passive preamplifier should not sound like ... nothing... should just turn down volume Yes?


    FiFI should be like close your eyes and musician is right there in your room playing for you.
    Can my FiFI make noise of plastic ruler whack on table ? working on it ...

    Do I like VO6 (Catalogue number) wall of sound first thing in the morning, that goes up to 11
    Try this ATR013 LP

    There's an American speaker I forget the name of but it is a four way and uses a 12 inch for the low bass and a 15 inch for the mid bass - on the grounds that you want the slam from the fifteen in the mid bass and the speedier twelve doing the bottom octaves, so you don't get too much overhang down there and have it slow the whole pace of the music down. That makes sense to me.

    Yes been I while (30+ years) and can't remember model at the same time I was moving around 68 Kw of electrovoice and tanoys
    PS my post is just a collection of toughts I had while reading this tread I am not looking for conflict just brain farting on the fly
    If they make tum tum sound instead of Pum pum they JBL are ok by me.
    Old brain fart Mia Martini at the time wanted Ge be lee (JBL in Italian) PA toke us quite a while to find out WTF she was going on about.
    Same toughts I keep for myself ( I wish my ex GF was as loud as 70 dB ( which is not loud at all) (got to measure the fridge and that is pretty much there IMO)
    But if one like to do the mat (My mat is worse than my spelling BTW) 3dB increase is double the volume so 86dB speakers at 1W 16 dB difference got to divide 1 watt by 2 about 5 times
