breaking a 135........ im losing hope

[slowfkncar]

Usually those "simple" ported boxes are the ones that get the loudest with the best frequency response.

Thats not true, everyone is doing bandpass enclosures now, so those are the best.

They are the in thing!

Ported boxes are like sealed boxes now days, if it aint bandpass it aint worth a damn.

Who cares that a simple ported box would walk all over this bandpass, its garbage because its not bandpass...

I'm sorry was that sarcasm?

If you know a enough about designing an enclosure you'll know..

Everyone is doing bandpass so they are the best!!!! I will remember that sir lol.

so ive had my mazda for just over 2 months now and my sound system for over a month. ive got 2 sa-10s in a 4th order tuned to 47 on an audison voce uno at 2 ohm. so roughly 1200 watts rms. for the life of me i cant get it over a 135. ive tried a new port and only gained a db from the origional port which is 133.

A Mazda what?

4th order isn't some magical paradigm to automatically get loud. I've got a simple skar Ivx 10 in my ram single cab on a 200rms kicker amp in a simple ported box that is doing 138 on the term lab in the 30hz range.

Usually those "simple" ported boxes are the ones that get the loudest with the best frequency response.

then please explain to me why most of the musical record holders run bandpasses? pipo, mick, gibson, bowman, kilian, etc

Because, you said "musical"

exactly. Because who cares for burps? Record holding cars on burps don't typically run bandpasses, just burp boxes/walls. Now if you wanna be musical that's a different story.

OK dude. This guy needs help breaking his 135. Obviously he does care about numbers. Why am I being preached about musical enclosures when this dude just simply wants to break the 135? Nothing personal bro. But saying a 4th bandpass is louder then a 4th ported is like saying sealed is louder then ported. Which is TRUE in musical form,most frequency's will be pretty loud in a sealed vs a ported where they have a narrow peak. But as far as breaking 135 db, this guy needs to figure out why he is getting 6.5" subwoofer scores

IS your trunk sealed off? That's going to make a huge difference, but you haven't given us enough info yet.

Knowing more about the vehicle in question would help this thread out alot.

It is a mazda 3 sedan. Gonna try and get pics

Was the box made by yourself, or is a ready made box? Is the box leaking anywhere? Does the sub woofer have a flat surface to seal to? If you can, have you tried rotating the box? More info bro. Provide us with info, we will tell you whats wrong and how to fix it and help you get a better score.

Here's the box design

1.18 Cubes sealed / 2.71 Cubes Ported after sub & port displacement. Port is 4 x 7" in 28 sq inches of port area. Tuned to 47.5hz

No leaks anywhere. I would try to rotate box but kind of hard as the way I have everything wired and set

I gave my single 10" sub more port area than you gave your 2(36"). Lots more tuning and you should be able to get it.

[RooTxBeeR]

Still didn't answer who designed and built it. Also, think 28in of port is way to little.

[WadeTustian]

I tried a port with roughly 58sq inches only to find a 1db gain
