Triticum Agricolam Posted March 21, 2014 Report Share Posted March 21, 2014 OK, based on my what I saw when I modeled your subs, with a 4th you can get about 4 db more than what you would get out of a ported box. But you will only get that increase for about 10 Hz above and below what you have the 4th tuned to. The ported box will be louder lower and will be a lot more musical than the 4th would be. The ported box will also be a LOT smaller. Disclaimer: the numbers I gave you are only based on software models, what effect your vehicle has on the output is impossible for me to determine.

Tarball Posted March 21, 2014 Report Share Posted March 21, 2014 For the record a ported box is 4th order, bandpass vs ported is what you are looking for.

Aj11 Posted March 21, 2014 Report Share Posted March 21, 2014 don't mean to Jack the thread but i have a question concerning this topic. as some of you know I'm planning a new build in a grand prix gt. i have a Lil over 7cubes of air space in the trunk. i was planning on building the box In the trunk porting threw the rear deck lid with 4 4inch flared aero ports with 2 meso 15s. i was debating if i would be better off with 2 12s in a 4th order or the 2 15s in 7cubes. i love low low low bass, very musical.because i listen to all kinds of music..rap, rock, jam band stuff (sublime, JBT, Jack White) , dance music like dubstep, skriilex, pretty much everything but county and pop crap. I'm not really going for dbs on the meter but a small hair trick Would be a plus! each ct meso (either 12 or 15) is rated at 2000w rms and will have its own ct 1400.1 given the info i supplied what configuration would suit my needs best? 2 12s in a forth 2 15s 7+cubes tuned to 30hz 4 4inch ports? jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out) Link to comment Share on other sites More sharing options...
CleanSierra Posted March 21, 2014 Report Share Posted March 21, 2014 For the record a ported box is 4th order, bandpass vs ported is what you are looking for. I read through all of the replies hoping to see this one. A 4th order is a bass reflex enclosure, or what we make reference to as a ported enclosure. A single reflex box bandpass is the 4th order you're likely speaking of. They're both 4th order enclosures, one is a bass reflex, the other is your single reflex bandpass. So to designate the correct meaning in the future, we need to refer to this as a 4th order bandpass enclosure to keep the two separate. Im not the one you want to try to troll. Just a fyi for you.

Rich Schenk Posted March 21, 2014 Author Report Share Posted March 21, 2014 so it sounds like for my application ported is the way to go because space is a factor.
