    i have a question with regards to the ratio of wattage and volume of air moved by speaker cone and how that translates into 'loudness'.i'm thinking of upgrading my 15" tko 65 to an ashdown 12" 200 mag.but i'm wondering how big the difference will be,especially since people seem to consider the ashdown 'quiet',and that it takes much more wattage to noticeably increase loudness
     
  2. I am one for the theory that bigger speaker=bigger sound. i played through a GK M150 in my college ensamble class, and while it was a decent amp, i don't feel it sounded that great (strange EQ as well). I as well have a TKO 65, and when i consider it in comparison to amps, it's somehow sounded bigger than both a Rogue 120 watt combo, and an ampeg b100r. I first noticed how loud it was when i was always drowning out my guitarist's 75 watt combo with a 12 inch.

    in short, 15 inch speakers spank!!!

    There is no direct relationship between wattage, speaker size and loudness. There is a direct relationship between frequency response, sensitivity and loudness. To make a valid comparison those are the factors that must be considered.

    so where does that leave me w/ regards to the question?

    Unfortunately not any better off than before you asked the question. You could find out quite easily if you could get SPL charts for the two units you're trying to compare, but I doubt very much that you'd be able to. The only other option is to try them out side by side: drag your rig down to a music store that sells what you're considering and let them fight it out.

    unfortunately, there are no hard and fast rules when it comes to speaker diameter and volume and/or tone. way too many variables. even with all the specs in the world, nothing beats a direct a/b comparison.
