.5DB louder

I guess the inside of the hole would work but the outside wouldnt. I have been referring to the outside with my comments without thinking of the inside.

maybe if there were like 10 baffles that blocked airflow or something

I think it would help. it would be more aerodynamic and maybe allow more internal sound to make its way through the cone. I'm sure it would turn out nice if done correctly. I'd def silicon around the subs from the inside of the box

If there is internal sound coming through your cones then i think you have a problem.

I wouldn't. Sound waves dont just magically come out the front of ur box. Soundwaves are produced from both sides of the woofer. if u play a sub free air u cant really hear any bass... it needs to be enclosed to the soundwaves can reflect off the inside of the box and project through the sub

How are sound waves projected through a solid object like the cone? Now correct me if im wrong, but the waves on the outside of the cone are what we hear and the waves inside the box are a control mechanism for the sub keeping suspension inline and everything. Unless you have a ported box in which you get the sound waves generated off the front of the cone and the waves projected through the port.

well soundwaves alone arent going to keep the woofer stable... it's the pressure from the woofers movement inside the box. And soundwaves always travel through solid objects. You've never heard neighbors partying or cars go by with music blastin w/ windows up? Happens all the time. Speaker cones are only paper or carbon fiber or aluminum or w/e. They're never too dense to pass soundwaves

you know what i just realized...the guy that said the "myth" was rounding it for a box for 4 12's. so when you guys say .1 or .2 of a DB that would be about .5DB when combining all subs. hmmm...still not sure tho. interesting thread tho IMO.

maybe also refering to ports like rounding over the edge of a slot port, however .5db is alot to gain from something that small

never thought about it like that

If you have multiple baffles, say 3" thick or more, yes I have seen gains from flaring the back of the battle. It is one of those trail and error things though (like most things in SPL).

Another thing that can help is duct-tape around sub. Yes, its true, duct tape can make you louder I have gained 0.7dB w/ a 1/4 roll of duct tape in 30mins //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Also PVC over the port opening can help in some cases. There are alot of tricks and such that can help you gain a few tenths.

Gorilla Tape works better than duct tape //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

There is something better than Gorilla tape, and its shiny //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Having a strong electrical would benefit moreover.

im gonna say not im gonna say the only place if you were to round over that you would see any gain and it would only be a tenth or 2 would be the port but then again i could be wrong i think someone needs to do a test and test this theory
