Gaining decibals.

experimentation is probably the biggest factor that will gain you the most... besides adding cone area and power.

Cone area and power typically net a lower increase in results then a few 100 or so hours of testing.

Yea, that will get you down in a hurry. Try having the same thing happen, but with a wall haha....Those are tough to swallow and know that you have rip it all back out..

Going from a basic setup...to a wall is 99% always an improvement. lol

what do people do wrong when it goes wrong??

Louder to the ear isnt always louder on the mic.

My XL 15 was louder on less power but that was not tl. I wouldn't mind going back to another 15 but 3.5 cubes swallows my trunk.

typically didn't measure twice before they cut...

Some times when chasing numbers what sounds good to ear will not work best on the meter. Same goes for any kind of mathematical figures we do. There is no way what so ever that we can design an enclosure (wall or other wise) and promise a particular SPL number. I don't care what any designer or builder suggest...it is in no way possible.

Have a few questions about gaining dbs. I like running a single sub due to box size requirements for my car. I know adding another woofer would be one of the best ways to gain on the meter but so does going to the next size woofer in most cases. What about adding sound deadener though? How much have you guys gained by just adding deadener? Which be a bigger gain going to a 15" or adding the deadener. Common answer is both but only able to do one at a time right now.

If you are serious about trying to get louder. Owning a meter is far more beneficial than adding anymore equipment.

That's a pretty low tuning frequency bro.

Yup thats how i like it

this.

start by making the trunk seal off 100% air tight, there are 2 vents in the trunk that vent under the bumper cover, make sure to seal those up real good

no such thing lol adding more power will all ways get u a few dbs usually only 1 or more lol biggest thing i did was bigger woofers and better box built gained 11.9 dbs by going with 2 18's and 8k

there is a such thing.

I gained over 4db on the tl by dropping my tuning from 1.2 down to .3 and trying a different port designSealing off the trunk wont always gain.

Id try a single 15 if you have the space.

sealing off the trunk is the most time consuming experiment for your car. subs all the way back with a long port/s at the cabin entry always works

yeah... I 've done a couple of sealed trunks that turned out great and did a couple that just flattened right out...
There's nothing better then a sht load of time put into an enclosure that doesn't work

mine is caught in between lol

About 145 sealed on the dash in the civic with my 18.

I should have my sub fixed in the next few days and switches out the 2 6" aeros for an 8". Should be able to meter again soon.
