If you really want to save weight......Get a titanium exaust.....thats like a 45lb savings. The stock airbox is about 25lbs, get a PRM intake......bam...saved 24lbs. Take out the spare.....bam....saved 20lbs. Get my drift??? Savin weight in all the wrong places my man.

 

I agree that trying to save weight in replacing speakers makes NO sense, but if you're looking for better performance than stock speakers and don't want more weight, Kenwood makes the dual mag which is a very thin, very light speaker that sounds pretty good... Good prices on the dual mags can be found at:

Nobody, you are exactly right that the small stuff adds up over time and effort...

and i'm glad that Honda chose the route they did... i didn't want a posh but slow S2000... (not to mention, i think the seats are WAY comfortable ) as much as i enjoy my stereo, i own this car to drive... a tight hardtop luxury coupe would much better suit audio needs if that was all i wanted...

but for speakers, we're not talking about double digit gains or losses... shoot, we're talking about less than a 1 gallon of gas difference in the tank or the difference between a full or empty wiper washer tank...
surely, you could add these couple pounds and pull all the insulation around the gas tank and rear deck out to compensate? or maybe pull all the cosmetic trim out of the trunk? or has all that already been gutted?

like Dave said -- you're chasing the weight bug in the wrong area... like an old friend of mine in college, he would spend thousands for lighter components to shave grams off of his mountain bike (playing the gram game as he called it...), even going so far as to sandblasting the Al frame to save paint weight -- but the fact that he was a mildly overweight 6'2 250 lb guy seemed to completely evade him...

anyway -- i honestly don't know of a good door speaker that will weigh in super light. most of the good stuff has larger magnets for better control, power handling, and response. not to mention, weight usually isn't a listed specification for car audio speakers -- i'm not sure where you're going to find out exactly what things weigh... (shipping weight is no good, as it will include boxes, grills, accessories, etc.) and i also don't know what the OEM speakers weigh in at, which is a number we'll need for comparison purposes.

 

btw -- Sounddomain.com shows the Infinity Reference CS6000 shipping weight at a mere 7.1 lbs. given that you've got a box, grills, manuals, packing, and wiring in there...

i'm guessing they probably weigh closer to 5 lbs total. even if the OEM speakers weigh 3 lbs total (which they probably weigh more), you're looking at +1 lb / speaker.

the CS series is generally a pretty sensitive speaker and doesn't require oodles of power to sound decent.

 

Thanks everyone for more recommendations on weight savings, but there aren't many that have escaped me (obvious things like the spare tire, toolkit and trunk material were gone before the car was even broken in). I wouldn't be concerned with the speaker weight had I not already removed 90% of all non-essential items already. (Yes, the interior--including door panels--has been properly stripped). What can I say, I wanted an Elise but they didn't sell 'em in America when I bought my S!

Ti Exhausts are insanely light weight, but I sold my JIC Ti due to all the unwanted attention I received from neighbors and the police. There are limits to even my maddness - deafness is one of them. Ridiculous prices for, say, a quiet AND light Mugen are another.

I'll check out the Dual Mags, Gamecock--those sound like just what I was looking for.

 

This sounds like a fun problem!

My first stab at it would be to look at coaxial speakers. Your average coax speaker doesn't have a huge crossover (crossovers weigh something).

If you want to go with separates (since you have an 02 and all), make sure you get neodymium tweeters, they are lighter (most car stereo tweeters use this kind).

If you want to get a bit more into it, check out www.seas.no. They make a bunch of speaker drivers and they list weights. If you go this route, you can have custom crossovers made at www.madisound.com (go with 6dB/octave crossovers and the cheap crossover components, they are lighter - really just explain your situation to them and they might be able to help). They also carry Seas speakers. Audax makes polymer chassis speakers (plastic is light). Madisound carries them, too. I think you should call up Madisound, and ask them.

I just googled...
Morel makes neodymium magnet woofers. Their mw-143 weighs 0.95 kg for a 5 1/4" woofer. Madisound carries them, too.

If you go with separates, and want to get serious. I think you should get an Alpine head unit with bass engine pro. It can do active crossovers digitally in the head unit. Then you can get rid of the crossovers in the doors. Probably will sound great, too. You will have to run another pair of wires for the tweeter, but hey, 18 ga wire will do it. I bet you could get away with < 1/2 lb of wire.

If you go with 5 1/2" instead of 6 1/2" there will be some weight savings, all else equal.

 

Not that I bothered to check the stock speaker weight...

 

I've chosen Focal components

Has anyone had any experience installing alpine 176A 6.5 components in the front? Will they fit?

Also, I'm thinking about installing alpine type-r 2 way 134A 5-1/4 in the rear. Will these fit without having to cut any metal?

 

i don't know that you can do this... most of the Alpine heads don't offer crossover points that are high enough to work w/ components... you'd need to cross in the 3000 hz or higher range, and the Alpines generally only go to about 250hz.
