in the house off two horn loaded 12inch subs, and a 2 X 500watt house amp.

guess I'll let you guys know how it goes, if I'm still around when I finish the horns.

single 12 in a horn, off about 60watts did 129dBs, so I don't see why 140 isn't possible.

thanx for your time.

seeya people.

Why 140 Skinnyguy should be getting at least 150 with two 12's mate.

I hit 150.9 today with two cheap ass tens.

in the house?

and I don't consider $500 each or whatever "cheap ass" these are $95 12inch subs...

lets see your two 10's get anywhere near 140dBs in a BIG ROOM off 500watts each, in MUSICAL boxes...

Why not? they will outperform your $95 12's by the same amount as they are worth when applied in the same application.

Why are you here, the people on Termpro don't care, nor do we!

oh, what was that? you only did 140dBs in the car? with the same subs? oh well

Yeah, except I don't make threads about it.

Burp your boxes at 33hz and tell me what you score, mate.

140db in a car the size of a charger is an awesome score nonethless.

I dont think people care how high your numbers are.

The fact of the matter is you have never done a decent number in a comp yet you still mouth off.

Whats wrong you finding it hard getting past 140 with decent gear? You gota termlab now where are the friggin numbers.

Stop yapping i can fart louder than 140db.

well, I'm aiming for 140dBs at 38Hz... so at 33Hz, they might do 135dBs in the house

but time will tell



I'm not mouthing off... :huh:

Yeah but the point here Skinny is that those subs were designed for in car use dude.

Noone cares what you do at home.

Bring it to the lanes we arent scary noone is going to hold it against you that your brain is slightly malnutritioned .

As a matter of fact we will love whooping your ass .

Dude you gotta good job now your making money got yourself a termlab, so why not splash out on a small hatch some decent gear and start competing.

Nah George he has to keep building horns, getting crap numbers and then signing up to tell people who couldn't give two f*cks

Because that's what losers do ya know!

maybe you missed the whole point of this thread? lol

"I'm aiming for 140dBs in the HOUSE"

now that we've cleared that up... a woofer is a woofer... its a voice coil, a cone, a fixed magnet, a surround, and a spider... oh, and a basket.

is there a difference between a "car subwoofer" and a "home subwoofer"? not really... if anything, this pioneers are more for home use, as in my opinion, a "car subwoofer" would suit a small, sealed box, as a car is only small, and these Pioneers do not.

would you like me to buy a "home audio" subwoofer? just so I can say its a home sub, and not a car sub?

I imagine these horns would do 145dBs in the car, except its going to be SS1-2 WALL, because the boxes are too big....

right now, I'm looking into buying some GOOD 10's, and a high powered amp, and making a pair of small horns to go in a VAN!!! yes, a VAN, because I reckon I can fairly easily make it to 150dBs, using the efficiency of the horns, rather than making use of a small cabin...

make sense?

why must we always argue? I want to see Australia take out some of the WORLD records, but with all this arguing, nothing ever happens.

dude, you MAY be the loudest Street A in Australia, but you're still like 6dBs off the world record!!!

And your nowhere near any record so we shall leave that for another thread . None of Australias numbers are near a world record so i dont see why i have to break a world record to get your respect. And its not 6db's its less than that .

Now if you want tens and amps see me ill help you out but i wont sell you Soundstream cos its to good for you .

If you havent noticed i am pretty much getting louder by the day so WHAT YOU RECKON you will do in a car i dont think is achievable except in your dreams.

Nowi do agree no point in arguing and noone is really arguing here we are just saying that you need to provide some decent numbers dude.


Oh and horns are efficient up to a point where you hit a barrier and you cant move any higher.

There is no such thing as the perfect box. And once you start experimenting with more power and better woofers and getting higher numbers youll see all the other problems that will arise.

lol, I've been playing with an 8inch Venom...

reckon I can hit 140dBs with one in the car... LOL!!!

just so you know

I'd rather play with the 8, so I KNOW I can hit 150dBs with two 10's, and alot more power...

but then, I'd rather not spend hours testing with a stupid 8...

so, I've reached a stale mate basically...

I really want to try my horn in a van, because I have a feeling it'll be louder than in the station wagon, but no one I know has a van it would seem...

3....2....1.... and ban

What you don't seem to grasp is that output efficiency at low power does not translate to output efficiency at high power. It's all about motor strength with SPL. Your sub & box may be efficient at low power when it is within its efficiency range, but when its being pushed hard, it will end up struggling to push air into the horn rather than out of it. The horn itself becomes a restriction. To extrapolate and say you can easily make 150db is futile dreaming.
