Im currently deciding what type of box i should put my brahma 12" in. I have read many sceptical views on the internet on how effective such enclosures are. Does anyone have any first hand experience with these boxes? thanx
im not sure i have read that they are quite good but i havent had any first hand experience maybe someone else can enlighten you
I have been looking at these for about a month now and was almost positive that I was going to get one but now I am not becouse you can get just as good SQ and SPL out of a well built ported box. That would be a much cheaper route anyway.
They're really hard to built correctly. So, if you're a little off, you won't get good results, resulting in poor SQ and mediocre SPL benefit. That's more than likely the main source of bad reviews. If designed well, though, they do hit hard. Snail Shells don't quite have the SQ of a ported box, but it's pretty good.
actually jon, i've heard from user WITH snailshells that not only was the spl much higher, but the sq was much better too. from a few, they've snailshell didnt sound all boomy like most ported boxes, hit a great on lows and highs, and hit tight and accurate like sealed. those boxes must have a pretty high qtc and flat response f3
Ported boxes can sound very tight and accurate as well. I guess I should have clarified. I prefer SQ designed ported boxes over snail shell. Compared to a higher tuned ported box or SPL designed ported, I'd take the snail shell for SQ no doubt. For ultimate SQ, I like AP membranes though, but they don't increase SPL, they're actually a little less efficient than sealed.
i see it like this give the box or Ap a whirl; proceed with caution as testing and in the end you will be sucessfull esp. with help from others like jon to give you input. And as always do your homework before tackeling a project. (knowledge is power) (saves headaches and agravation too lol) Only thing stoping you from possible sucess is trying. Doing nothing keeps you where you are.
They are difficult to implement, and I wouldn't recommend it unless you are willing to do a lot of work for sound deadening and install. The rear wave has to totally seperate from the front. Anyway, AP isn't good for SPL as it's a little quieter than sealed. I can't really help you w/ snail shell, horn equations and 1/4 wave theory, haven't built one, only heard custom ones. I'd recommend you go to www.powered4sound.com and have them custom build you one. As far as ported, that's a good do it yourself project and if you have building skills, a custom built ported will sound better than any prefab you could buy.
