discreet Posted June 23, 2012 Share Posted June 23, 2012 [b]Is an '8 X 10' equivalent to a '1 X 80'?? Eh??[/b] I'll say right now that this is not entirely a serious post, but... If a cab has EIGHT drivers that are TEN inches in diameter... and leaving aside for the moment considerations such as response speed and all that... and of course completely ignoring technical and manufacturing issues... Does this mean that an 8 X 10 is equivalent to ONE driver EIGHTY INCHES (6' 8") in diameter..?? Or what?? Eh? Eh? Quote Link to comment Share on other sites More sharing options...

Mr. Foxen Posted June 23, 2012 Share Posted June 23, 2012 You have to square it because it works on area not length. The Pi part cancels out. Quote Link to comment Share on other sites More sharing options...

TimR Posted June 23, 2012 Share Posted June 23, 2012 I would think it was fairly obvious from your diagram. An 8x10" cab would just come up to his armpits. Quote Link to comment Share on other sites More sharing options...

sixdegrees Posted June 24, 2012 Share Posted June 24, 2012 (edited) My rudimentary maths, and basic knowledge of speakers, tells me that you'd need a 100 x 8 cab to get the equivalent surface area of a 1 x 80 cab. But it's late so I could be way out. Edit - I've now realised I've made the calculation based on 8" speakers. Told you it was late.

[/quote] Yes (well, rectangular, actually...) I had a pair of polystyrene speakers (the 'cone' was flat and the polystyrene chassis was ultra-thin...) They were to be hung on a wall in a narrow cab, a bit like a framed painting. They worked very well with my Cambridge hi-fi amp at the time. I'd like another pair, if I got the chance. As for the 1 x 80 speaker, it's been done. 'Back to the Future', anyone..? Edited June 24, 2012 by Dad3353 Quote Link to comment Share on other sites More sharing options...
paul_5 Posted June 24, 2012 Share Posted June 24, 2012 I had some speakers made of wood once. They wooden work. Getting my dressing gown (it's early). Quote Link to comment Share on other sites More sharing options...
Jazzneck Posted June 24, 2012 Share Posted June 24, 2012 (edited) 8 x 10 = 628ish sq. ins. 1 x 80 = 5025ish sq.ins. and likely to need a humungeous magnet and cab. Frig it - wouldn't bother, likely to be too heavy, unless I could afford a roadie. But imagine it built in to the wall of the back of the stage - you could nail yourself to the floor and, BOOM, blow the punters clean out of their cotton socks and seats straight through the exit doors backwards without their feet touching the ground. Now that would be a show, wouldn't it? Edited June 24, 2012 by Jazzneck Quote Link to comment Share on other sites More sharing options...
TimR Posted June 24, 2012 Share Posted June 24, 2012 I wonder if the 8x10 was 1600 watts would that make the 1x80 about 14kW? The internal cables and cooling would have to be huge. Quote Link to comment Share on other sites More sharing options...
Tankdave Posted June 24, 2012 Share Posted June 24, 2012 8 x 10"s is roughly the same as a single 28" speaker, now that sounds a bit more do-able Quote Link to comment Share on other sites More sharing options...
lojo Posted June 24, 2012 Share Posted June 24, 2012 To get a single speaker to match the area of an 8x10 you would need a 1x30 (28.28) Quote Link to comment Share on other sites More sharing options...

xgsjx Posted June 24, 2012 Share Posted June 24, 2012 So why don't us bassists use Kicker subs? [quote]How do you improve on a patented mechanical brute? Since the 18-inch S18X debuted in 2003, KICKER engineers have been working to make SoloX more advanced. This year they went all the way, creating the world’s ultimate bass machine. Patented square subwoofer technology designed with the serious autosound competitor in mind, SoloX Subwoofers go where no others can. The 10-inch S10X, the 12-inch S12X, and the absurd S18X… it’s KICKER ingenuity to the umpteenth power. The SoloX earmark is the SPAIR (Simple Pull Apart Insertable Replacement)™, the patented cone/coil assembly that differs from other field-replaceable cones because the woofer’s cast-aluminum basket and massive motor assembly (BAM) remains intact in the enclosure during reload. In 2008 the SPAIR, just as the SoloX itself, withstands unnatural amounts of abuse while retaining the infrastructure for thunderous bass that earned it both competitive SPL (sound pressure level) and sound-quality world championships within weeks of its original release. Additionally, the newest SPAIR retro-fits into the previous generation of SoloX BAM if needed, with no modification. More KICKER firsts provide protection against ruthless heat and other potential hazards. The distinctive UniPlate V.2™ hyper-extended, pole/backplate assembly stays cooler with X-Vent™ technology (pat.pend.), yielding enhanced heat transfer for maximum power handling as well. This breakthrough in subwoofer motor construction increases linear magnetic fields around the coil gap for superior cone-motion control, all while releasing pressure under the cone for freer suspension and enhanced low bass. OK, it slams. Further heat dissipation comes from the vented pole’s ARCTIC (Aluminum Rapid Cooling Thermal Induction Centering) Cap™, creating a Venturi-effect and forcing greater amounts of cooling air through the X-Vent, all while its high mass acts as a heat sink. SoloX’s dual voice coils and copper-clad-aluminum, edge-wound coil wire are oversized to withstand extreme heat too. No KICKER woofer possesses this many features to remain so reliable. Additional cooling comes from KICKER’s perimeter venting™, pumping out heated air trapped beneath the S10X and S12X’s S3 Triple Spider Array™ and replacing it with cooling outside air (Quad Spider Array on the S18X). The one-piece, injection-molded cone’s new spoke design supplies structural bracing and contains a rolled outer edge to increase rigidity and decrease flex under high excursion. Stitched surround helps to prevent cone/surround separation. SoloX subs also utilize removable spring-loaded binding posts, making connection to any type or size of wire quick and easy. For complete system flexibility, SoloX comes available with dual 2-Ohm or dual 4-Ohm voice coils, as do respective SPAIR models.[/quote] Just found the answer...

4 Strings Posted June 24, 2012 Share Posted June 24, 2012 Question needs more info. I understood it wasn't just the diameter of the speaker but how far they can move in and out. Double the couple of mill they move by a couple more mill and you have the equivalent of two speakers. Also my turn for this bit: [attachment=111381:Squares.jpg] Quote Link to comment Share on other sites More sharing options...

[/quote] That's a degrees of equivalence thing, if you are talking linear measurements, its all about area, once you get into volume displacement, new game, area still tends toward sensitivity to voltage, but more excursion means more power handling, which can make up your max SPL.

Jazzneck Posted June 24, 2012 Share Posted June 24, 2012 (edited) Strewth this is getting technical, or as my old boss used to say, "Bullsh*t Baffles Brains and I ain't got no brains". I'm off to bed now to refresh and will consider the air movement, sensitivity, coil and magnet requirements along with the heat dissipation questions in the morning. Goodnight all.
