[QUOTE="Suicide Bobb, post: 7114606, member: 617319"] Mods: I think you should sticky this, or suggest another title for the thread and sticky the new thread. This will reduce a lot of threads that ask "How many X sized speakers does it take to equal the cone area of nX sized speakers?" and also hopefully be a quick reference sheet for even the experienced to look at. [B]THESE NUMBERS ARE NOT EXACT![/B] I rounded for almost all of the numbers, and for the charts that compare X speakers to nX speakers, I only picked those that were closely related in cone area. Since my calculator does not have a Pi function, I multiplied the radius squared by 3.14, which as most of you know is close enough. This chart is only meant to [I]give you an idea[/I] of how similar the cone area of X speakers is to nX speakers. As you can tell, I only went for common sized speakers. I'm not going to include speakers like the ear-shaped Yamaha woofer, or some one-off sub like the custom MTX Thunder 1,000,000. The sizes I chose are those of known production speakers (off the top of my head). Please let me know of any that I left out, and I will update each category to include them. -------------------- [B]One Speaker[/B] [COLOR=red]Diameter of speaker[/COLOR] | [COLOR=blue]Cone area of speaker in square inches[/COLOR] [COLOR=red]34"[/COLOR] ---> [COLOR=blue]908[/COLOR] [COLOR=red]32"[/COLOR] ---> [COLOR=blue]804[/COLOR] [COLOR=red]22"[/COLOR] ---> [COLOR=blue]380[/COLOR] [COLOR=red]21"[/COLOR] --->[COLOR=blue] 346[/COLOR] [COLOR=red]18"[/COLOR] ---> [COLOR=blue]254[/COLOR] [COLOR=red]15"[/COLOR] ---> [COLOR=blue]192[/COLOR] [COLOR=red]13.5"[/COLOR] --->[COLOR=blue] 143[/COLOR] [COLOR=red]12"[/COLOR] ---> [COLOR=blue]113[/COLOR] [COLOR=red]11"[/COLOR] ---> [COLOR=blue]95[/COLOR] [COLOR=red]10"[/COLOR] --->[COLOR=blue] 79[/COLOR] [COLOR=red]8"[/COLOR] --->[COLOR=blue] 50[/COLOR] [COLOR=red]6x9[/COLOR] ---> [COLOR=blue]42[/COLOR] [COLOR=red]6x8[/COLOR] --->[COLOR=blue] 38[/COLOR] [COLOR=red]6.5"[/COLOR] ---> [COLOR=blue]33[/COLOR] [COLOR=red]4x10[/COLOR] ---> [COLOR=blue]31[/COLOR] [COLOR=red]5x7[/COLOR] --->[COLOR=blue] 28[/COLOR] [COLOR=red]5.25"[/COLOR] ---> [COLOR=blue]22[/COLOR] [COLOR=red]4"[/COLOR] ---> [COLOR=blue]13[/COLOR] [COLOR=red]3.5"[/COLOR] ---> [COLOR=blue]10[/COLOR] [COLOR=red]2"[/COLOR] ---> [COLOR=blue]3[/COLOR] -------------------- [B]Two Speakers[/B] [COLOR=red]X Speaker[/COLOR] |[COLOR=blue] Equivalent of 2X Speakers[/COLOR] [COLOR=red]3.5"[/COLOR] ---> [COLOR=blue]5.25"[/COLOR] [COLOR=red]4"[/COLOR] ---> [COLOR=blue]5x7[/COLOR] [COLOR=red]5.25"[/COLOR] --->[COLOR=blue] 6x9[/COLOR] [COLOR=red]5x7[/COLOR] ---> [COLOR=blue]8"[/COLOR] [COLOR=red]6x8/6x9 [/COLOR]---> [COLOR=blue]10"[/COLOR] [COLOR=red]8"[/COLOR] ---> [COLOR=blue]11"[/COLOR] [COLOR=red]10" [/COLOR] ---> [COLOR=blue]13.5"[/COLOR] [COLOR=red]11"[/COLOR] ---> [COLOR=blue]15"[/COLOR] [COLOR=red]12"[/COLOR] ---> [COLOR=blue]18"[/COLOR] [COLOR=red]15"[/COLOR] ---> [COLOR=blue]22"[/COLOR] [COLOR=red]22" [/COLOR]--->[COLOR=blue] 32"[/COLOR] -------------------- [B]Three Speakers[/B] [COLOR=red]X Speaker[/COLOR] | [COLOR=blue]Equivalent of 3X Speakers[/COLOR] [COLOR=red]2"[/COLOR] --->[COLOR=blue] 3.5"[/COLOR] [COLOR=red]3.5" [/COLOR] ---> [COLOR=blue]5x7/4x10[/COLOR] [COLOR=red]4" [/COLOR] ---> [COLOR=blue]6x8/6x9[/COLOR] [COLOR=red]5x7[/COLOR] ---> [COLOR=blue]10"[/COLOR] [COLOR=red]4x10/6.5" [/COLOR]---> [COLOR=blue]11"[/COLOR] [COLOR=red]6x8[/COLOR] --->[COLOR=blue] 12"[/COLOR] [COLOR=red]8" [/COLOR] ---> [COLOR=blue]13.5"[/COLOR] [COLOR=red]10" [/COLOR] ---> [COLOR=blue]18"[/COLOR] [COLOR=red]12" [/COLOR] ---> [COLOR=blue]21"[/COLOR] [COLOR=red]18" [/COLOR] ---> [COLOR=blue]32"[/COLOR] -------------------- [B]Four Speakers[/B] [COLOR=red]X Speaker [/COLOR]|[COLOR=blue] Equivalent of 4X Speakers[/COLOR] [COLOR=red]2" [/COLOR] ---> [COLOR=blue]4"[/COLOR] [COLOR=red]3.5"[/COLOR] ---> [COLOR=blue]5x7/4x10[/COLOR] [COLOR=red]4"[/COLOR] --->[COLOR=blue] 6x8/6x9[/COLOR] [COLOR=red]8"[/COLOR] ---> [COLOR=blue]15"[/COLOR] [COLOR=red]10"[/COLOR] --->[COLOR=blue] 21"[/COLOR] [COLOR=red]11" [/COLOR]---> [COLOR=blue]22"[/COLOR] [COLOR=red]15"[/COLOR] ---> [COLOR=blue]32"[/COLOR] [/QUOTE]
