Is there such a thing?

Big heavy powerful subs like the PG elite 12d, Re XXX, JL w7 etc are all awesome subs but at a big weight disadvantage.

So who makes a light weight SQ sub of the calibre of the ones i mentioned above.

ok most lightweight sub's use Neodium magnets, these are quite good but they have one small downfall. when they heat up they lose there magnetic output and therefore lost musical output and control etc.

you could look at something like a IDQ or a boston pro, both are exelent for SQ (not as great output as xxx/w7/brahma etc) and they use conventional magnets yet are still alot lighter than the others

I had a Dynaudio MW-190, weighed about 2.5 kgs and had a mounting depth of like 4 inches.

Not massive output but certainly enough for a SQ setup.

Howcome the weight is a disadvantage? I dont notice my IDMax in its huge box sitting in the back of my 1.6 litre woman mobile..if its because you think your car will go slower. If that isnt the reason then sorry for the pointless post.

how much would one of the lightweight subs cost?

Alto Mobile Falstaff, maybe? Pretty thin and lightweight...

Mmmm Pepsi...
How's that thing sound bodopa?

Those things look almost identical to Phase Linear Aliante's, although a little different from the side.

Theres a store here selling a pair of 12" Aliante's still in box for $600 NZ... so tempted

I think his talking about the disadvantage of his car handling not as well ect

I sure notice it when I have my 2*12" in the garage instead of my boot...

hehe, cone area looks like a golf ball

Btw, it's a 12 incher...

As to how it sounds, take it as you will, but for me it's the resolution of that sub that amazes me. Not how low it can go (even though I believe it can). Most subs that I've heard were just...how do I explain this...they gave tremendous output given the current that they received, but the end result was just like a "blob" of a sound. Kinda bloated, fatty type of sub bass. Of course, it depends on the install and tune but in my car it sounds "just right", with high definition and resolution for a transducer that pretty much reproduces anything below 40 Hz.

I'm just looking to find a SQ sub that dosn't weigh so much.

A car is still a car first to get you from A to B.

Adding a system such as what i had was wonderful for my ears but not for the car.

I'm now looking at how to build a SQ competition winning car but without excessive weight.

The sub is just one part of the equation but also in most cases happens to be the heaviest single item in a system.

Whatabout Phase Linear Aliante Subwoofer? It is a very nice subwoofer eventhough it doesn't hit as low as RE or ID or Treo or Brahma subwoofer and it costs around the same price with IDMAX.

Like RE and want 95% the SQ for a 10th the weight and 5th the cost? Try the RE12. Next issue of ASM has a direct comparison of these two woofers using CAASQ as the scoring system.

The sub and box...you can save a bit of weight going a F/G and mdf mix box. If SQ is goal their are too many subs that sound fantastic and dont weigh a ton, too list, they just dont go that loud compared to their heavy brethren. Thats never going to be an issue with a SQ car as SQ isnt tested at very high volume.

why is weight a problem???

why do you need any performance on the road??

if you occasionally need performance make the amps and sub box easily removable with the use of anderson plugs (for the amps power/grounds) and bolts (allen key type bolts are a little better to slow down theives too).

If you drove my car with all the gear i had in it you would understand. The whole balance of the car was thrown out.

I will probably still put my Elite 12d in my next install.
It will be mounted in a fibreglass enclosure up in the back corner of the boot.

Im looking at running just a 2 way up front and the sub.

It's nice to have a big system but this time im going back to basic's.

Less components means less weight which is what im looking for.

iv'e done some experimenting over the last couple of weeks and i know it will sound great.

Now if i can only get it ready for the first SQ comp here in Sydney.

Do you have any objective proof of this? 0-100 times (even on gtech or similar) or lap times?

Otherwise, you do realise that you may just be imagining the difference

You do realize that the amount of petrol in your fuel tank can often make more difference to your performance than an average (on the forum) enthusiast system. (ie, a decent front stage, two amps, a single 12" sub, MDF box)

Anyway, I agree with Cyberpunky, there are plenty of SQ subs out there that don't weigh anywhere near 20+kgs. -/+5kgs ain't going to make much difference to your car's performance anyway.

Trust me, John has more than an "average" system. Look back through this forum at the pics, easily 50kg in raw equipment alone (probably more!)

If I'm not mistaken the design/engineering team of the Aliante was the same as the one who made the Falstaff, so it makes sense if they (the Aliante and The Falstaff) share similar design/engineering principles.

ok

heres the go

freeair sub..no idea what you would use though

remove spare tyre (or dont put one back)

remove un-needed amps....done

but seriously to really know the sub box and stuff is in the car you have to push the car into a corner at HIGHER speed than you would ever do normally

my sub box alone effects my cars handling but only when pushing closer to the tyres limits. The car now pushes into the corner at high speeds where as before the sub box was installed it was more neutral feel. You jsut have to adjust your driving style to suit the new weight displacement.

to improve handling you should aim to get the weight as close to the rear wheels as possible. The further away from the rear wheels you go the more mass will effect handling in corners, then you end up with a very slow 911 . HOwever mass alone will directly effect braking distance.Upgrading brakes and tyres can help here though.

best solution

get a track car and use the stereo car for the tow car

in a different thread, he spoke about suspension sag and fatigue in the rear suspension componentry to the point of replacing a significant amount of expensive MB suspension! :shock:

not good.

heres a simple idea. get someone to remove the subs and head unit (so u cant tell if they are gone or not) without you knowing, thrash the car from full tank to empty, then get tehm to either put the subs back or take them out (you wont know what they are doing) then fill it and trash it again, and deicde which is better, this way you wont have the mental thought "its coz of the subs"

Trust me the weight was big problem.

If some of you don't understand just go to your local hardware store and get 3 40KG bags of sand and put it in the boot behind the rear wheels and drive it around for about a week.

It made driving in the wet a bit hairy.

The components i had in the boot

1 x Elite 12d sub
1 x Titanium 1200.1 amp
2 x Titanium 1000.2 amps
1 x Titanium 500.4 amp
1 x Titanium Powercore
1 x Titanium EQ30
1 x Titanium Bass cube
1 x Titanium Elite 5 cross over
1 x Titanium DD10
1 x Optima yellow top

Plus 0/1 + 4 and 8 guage cables and interconnecting cables. You would be suprised how much cable's weigh.

The sub box was 56 litre's made of 25mm MDF.
MDF panel's on the boot floor, left side, right side, up the back and boot lid. Then MDF panels as covers.

The whole boot and boot lid was also sound deadened.

Add a full tank 80 litres of fuel, 3 kids in the back seat, my wife in the front passanger seat an me about 85 kg.

Yes my car was a dog to drive.

wow lots of stuff

free air sub would be the only choice for weight reduction

you could reduce the amp numbers, , get rid of the ti500.4, tddi10, basscube, power core and elite sub + sub box

just have front stage amp, passive x-overs, light sub + subamp and eq. then you can reduce all the wiring put back all stock interior panels, take out spare tyre use an mdf baffle to hold sub and componets on to the back of the rear seat hopefully you have a ski hole for the free air sub to fire into. Hopefully if all goes to plan all the stuff will sit inline with the rear wheel arches. Handling restored

Well at the moment my boot is a mess but this is what i am experimenting with.

The Ti400.2 running the Elite 5 and tweeter in the kicks.
The Ti600.2 bridged running a AVI 10" 4ohm sub in a fibreglass enclosure in the back corner of the boot. This sub and box i had from an earlier install.

Its sounds nice but lacks the deep sub bass im used to.

Another alternative is running the Ti500.4 front channels to the kicks, the rear channels to the 9" in the doors and the Ti 1200.1 for the Elite sub in a fibreglass enclosure similar the the fibreglass box i have now but bigger.

Therefore just 2 amps to run all the front stage and sub.

I just have to wait untill i get the 500.4 back from service before i can try this set up.

The aim is to use as little as possible but still have a top quality SQ winning system and still have a car thats nice to drive..

My kids are getting more into sports now so i need full use of the boot for all their sports bags etc.

Also this next install will be all stealth.

I'll get there in the end.

what about also moving the amp's to under the seat's if there is room.
that will move some of the weight forward so it's not all behind the rear wheels.
have the sub box as far forward in the boot as you can to get it over the rear axle and as low as possible. that will get the center of gravity down too and help with the handeling a little too
cutting down on the amp's you should be able to get away with 4g cable, less RCA's etc so that will save a little weight.

From memory, the Merc has the seat motors and safety boxes for the airbags under there?

John, what's your weight limit for the sub?

No there's no room under the front seats at all. I can't even get my hand in there.

I plan on having the amps mounted in a rack style behind the rear seats. That should be about in line with the rear wheels.

Ben to be honest i think im going to have a problem in finding a sub that will play as good as my Elite but weighs much less.

If there's no significant weight advantage then i don't see the point in changing.

I think its more of how to save weight overall now.

boston pro my pick.
i use one and love it, play's as low as you want and plenty of output. and pretty light also.
bit hard to get hold of now cause they have changed to the new G5 but i think fhrx have some left.
if you were in melb i would demo mine for ya.

I do have a soft spot for Boston speakers.

Wonder how some Z's and the the new G5 would sound in my car.

Sounds to me like you need to buy yourself an F series truck, a nice little F-250 should do the trick.

Um - AP mats anyone?

I am doing a car at the moment with nearly same components, and have used a F/G sub box. I think its significantly lighter than E320's old box. I am fitting it all this weekend so will find out how well it works then. I cant wait to hear this set up as Im thinking it should be pretty special. The elite sub and fronts should be the business. peace Cyberpunky Fudd Mar 24 2005, 11:00 PM QUOTE (Cyberpunky) No offence Bobby but after the sub he has had, I severly doubt he would be happy with a 10 regardless of brand.
