    Does size matter??

    jmain's (Jesse's) quest for another cab to compliment his 1x12 got me thinking: A few years ago BP had a list of speaker configurations ranked according to speaker surface area. Smallest to highest.

    Anybody have this list or a similar one? I personally don't recall the rankings, but I do recall being surprised.

    If I had to guess, I would say PJB has the most surface area with many tiny 5" cones, but that's just common sense - I'd like to see this list also!

    Note: Surface area doesn't mean better sound.

    That was one of the most useless and misleading things BP ever published. I'd rather it wasn't repeated here.

    To answer the next question, why Alex has this opinion, cone area (Sd) in and of itself says very little. As far as high frequencies go a larger cone will have lower sensitivity and narrower dispersion than a smaller one, so there's some comparative value there. As far as low frequency output goes cone area alone says nothing, it's displacement (Sd x xmax) that counts.

    Gotcha. So there's no "universal law", if you will, on surface area and tone?

    No. Over a two year period I tried close to 70 guitar speakers...10s, 12s, and 15s. Manufacturer doesn't matter either. I've played through 10s made for a guitar amp and 15s made for hi-fi by the same company; the 10s were much louder and bassier.

    what if someone compiled a list of speaker boxes in terms of displacement?:D...that would be a fun read.

    Need to add - driver to air coupling.
    i.e. Horn loaded designs and so much more efficient.
