I have been looking around for a box either made by a pro, or by a good company, the box i built is o.k, i can hear a nice change in notes from the sub but i think the box is taking away from some of the bass and very soon might cause my sub to blow (smells like speaker in my car and amp is fairly warm after a short trip)

i could get this box for about 70$, apperently the labrynth is just like "bose-tube technology" filtering out long waves, and its built for my sub,

thanks

 

wow what will ppl think of next... a new name for a folded port... new selling gimmick

this here is just the saddest explanation ever shown... aimed at the drawing they used... hmmm where is the right half of the vent actually going? into a side of a box ? so does that mean the one half of the box is sealed? and the left side is vented? or did I miss something

not meant as a personal attack to the OP, just an observation I made
download WINISD and build your own box. atleast you will learn something

 

according to their write up...the labyrinth allows "long low frequency sound waves to easily escape while short high frequency waves remain trapped unable to cause unwanted cancellation and distortion"...so, I guess if you use a low pass cross over, that defeats the purpose of the box??? These are just ported boxes..true folded horn designs do have advantages, but most are way to large to use in cars.

 

If your sub is smelling and warm after a short trip, something is wrong but it may not be only the box. Do you have an subsonic filter below the tuning frequency? Have you taken the RMS rating of your sub(s) into account, with the amp which is powering them? Are you feeding them a clipped signal? Is your electrical up to par?
SO many variables.
BTW I would not buy that labarynth port box, just my $.02

 

subsonic filter?... The sub and amp are matched, JBL GTO 1214D sub and JBL 3501 amp, sub needs 345 RMS and the amp only puts out 360RMS, so im not too worried as the things are set pretty low on it, no distortion or anything, as for electrical, no dimming headlights,

i thought my box was a bit crude on the layout and specs, im going to put it into the program above and see what i get,

 

That read on R/T was pretty funny. The only real advantage I can see from them using a labrynth port is that it lets you increase the vent area which is usually the fall down point for most premade boxes with port tubes.

 

BTW that posted box is tuned in the 40's kinda high i think

 

ok guys, im using WINISD to check my box and maybe design another, but its so hard to use! any tutorials or step by steps around?

 

You never mentioned if your box was sealed or ported (or i cant read). Even if your amp is matched to your sub, you still have to adjust the subsonic filter properly, especially with a ported box. If your box is tuned to 40hz then your sub has far less power handling below that point. And your amp does have a subsonic filter.

 

the box is ported, what exactly is a subsonic filter..?
