So I ported one of my Cvrs...

My cousin and I were bored the other day and I was explaining the sound difference between ported and sealed, he didnt think there would be much difference between the two... I'm currently loaning him my amp and sub so it's installed in a 97 dakota ext cab...

The orginal box was originally a little over 1.6 cuft feet, truthfully a little to small to port, but I did it anyways... :happy055:

I tuned the box down to 33hz which made the 4" port stick out of the box around 4", but in a pretty sorta way... Painted the box black, and the port blue... what we were bored?

Anyways, the results...

We threw in some 3-6 mafia and turned it up, big difference in spl and actually didnt sound bad at all... Over all it was well worth the 10 mins... :)

as mentioned, the box is too small, which will throw off the performance.
he'd really be awed if you built a quick box to proper dimensions for porting, and played it compared to the sealed box of proper size.

Stunts like these are why speaker companies don't like dealing with Joe Consumer, by the way. :) If the sub gets damaged and you try to RMA it, they eat the costs for the owner's mistakes.. that gets expensive if you look at a lot of the cardomain type examples of "how not to install speakers"

I love when someone wants to make a sealed box into a ported box.. so they just cut a big hole in the box.. and say "look it's ported now!"
hahaha

I orignally sold him the jbl amp and the 2 cvrs, he blew one sub and spilt a soda on the other staining the cone (otherwise didnt hurt it.) Anyways he bought a truck off me and in that deal I got the subs and amp back... Basically I'm never going to use the sub anyways so I figured why not, my table saw is in storage and even if it wasnt I didnt want to drive 30 miles to get a sheet of mdf for a sub I don't really care about...

I used the bcae1 box program, I compensated for the missing internal port volume by glueing in the same volume of wood on the inside...

It's ghetto, I know... I don't really care about the sub and it was just an experiment...

Stop making fun of me...

Maybe I'll get this metered then build another good box and show him the difference between a shit box thrown together and one thats planned out..

If only I could take away one post.... :help:

Hey I Need Your Help, I Bought A Lanzar Heritage 2600d Model For Only 140$ And It Says That Reaches 1000wrms At 1.3 Ohms, Somebody Ever Hear About This Amp Or Something? Do You Think That It Can Power 2 600w Rms Subs, Thanks

Yeah thats a peak rating, on an amp that won't run 1.3 ohm. We need to know the RMS rating.

what'd be really cool is if you could graph the response between the two boxes to see the differences, as opposed to just a peak SPL reading, ya know?

this should be a separate thread, in the amplifier section.
you shouldn't hijack someone else's thread, julio.
