What would be the best type of box

[chameleon30038]

I want to get an Audiobahn System and i know they make boxes also i wanted to know what would be best a Bandpass box, Slot Ported, or Sealed. Please let me know

Thanks

For an Audiobahn (assuming that you want SPL) I would go with a slot ported box. Bandpass box is really loud at certain frequencies, but not very all round responsive. Sealed, while loud, is more for a SQ setup. I would say with audiobahn, the slot ported box is the best bet, IMO.

tons of bass= ported
sound quality= sealed

The Flame Audiobahns will blow the plastic out of the bandpass boxes.
Lol

the choice is your own. if you have enough power do a sealed if not do ported. When i mean enough power i mean an amp that meets or exceeds the power rating of the sub.


as for flaming q's "blowing" boxes apart wtf do you build boxes with superglue? Try getting the right size box.

audiobahn while looking pretty with al the chrome, has alot of reliability problems, thier bandpass boxes are ONLY for looks and really sound like crap, especialy the triple 12" inverted ones is a joke, ported boxes are more efficient so they need less power to get loud but are also good for spl and sealed is good for sq,

audiobahn really though, think abou tmaybe going with another brand becaus audiobahn is like a bomz exhaust or having a body kit on your car, all for looks,looks overquality and cheap

i think the best kind of box is one that is almost completely shaved, possibly a little tuft of hair in the middle, and also one that is not too losse...oh, my bad..................another brain fart from me...oops lol

If you get good speakers and a big amp, go with the sealed box. I think it gives the best sound quality and hits the widest range of frequencies. A bandpass box will give you the most boom for your buck (i.e. being loud even with a small amp) but their are some frequencies that just don't hit and when you listen to songs with them it will annoy the hell out of you.

This is "borrowed" from the instruction/specs sheet of my Infinity "10 Referance subwoofer speaker and provides what I think is helpful info on different box types and what kind would work best:

The power-handling capability of any woofer is related to both its ability to dissipate heat and the maximum excursion limits of its cone. Once the speaker’s voice coil moves outside the magnetic gap, power can no longer be converted into motion and all the amplifier’s power is converted into heat in the voice coil. This voice-coil heating
is the largest detriment to speaker longevity, so overexcursion should be avoided. Since speaker-cone excursion is different for each type of enclosure, power handling is different for each enclosure.

Sealed enclosures exert the most control over the motion of a subwoofer because the air inside the box acts like a spring against the motion of the woofer cone. Larger boxes allow for more excursion, thus providing more low-frequency output for the amount of power used. When placed in a sealed box larger than the Vas of the subwoofer, it will perform as if it were in an infinite baffle installation.

Vented enclosures have the lowest amount of excursion for the amount of sound output. This is a result of port output reinforcing the sound output from the woofer. The mass of the air contained in the port provides an acoustic load on the woofer’s cone at the tuning frequency, and this added mass decreases woofer-cone excursion. Vented boxes do not provide adequate woofer control when driven below the port tuning range, so proper design is important. A vented bandpass box will have the lowest overall cone excursion, provided a subsonic filter is used.

• Voice-coil overheating and burning due to overexcursion are often caused by overdriving an amplifier into "clipping." A severely clipped signal, or squarewave, contains nearly twice the power of a clean
sine wave at the same level. Bass that sounds broken up and distorted at higher volumes usually indicates that the amplifier is clipping (i.e., being asked to deliver power beyond its rated power).

• Infinite baffle or “free air” mounting applications allow for greater cone excursion than subwoofers mounted in an enclosure. In order to compensate, recognize that the power-rating value of the subwoofer
will likely be half its rated power in this application.

• Study the excursion curves on the enclosed Reference series data sheet and note the differences for different enclosure applications. The type and size of box used will produce different excursion demands
on the enclosed subwoofer and, consequently, different levels of power handling. As long as recommended parameters are used, the subwoofer will perform properly in its enclosed environment. However, any design deviation may result in less than optimum performance, and may also subject the subwoofer to overexcursion (i.e., where the voice coil leaves the gap) that can eventually damage the speaker. For additional help with this issue, please contact your authorized Infinity dealer.

I had 70 dollar audiobahn high excursions runnign form a JBL BP300.1, my friend had 250 dollar punch HX2's running off of a BP300.1 and mine sounded just as clean and just as loud, im sure if they were actually tested for SQ or SPL thered be a difference but to our ears we couldnt tell a difference. we each built outr own cuztom designed porteed box and both were in 2 door coupes with the subs firing backwards.

personally I think audiobahn is good stuff.

[unusualcivic]

if he had those hx2's running at their rated power he'd have murdered you in spl.

[94tegRS]

I idnt have mine near their rated power either, im not saying it is better or worse than RF stuff, IM just saying that when you dont have tons of money to spend on 10 watt amps and hundreds of dolar subs, you dont have too. but put the AWT12X with its rated power to the power HX2 with its rated power and I could still do it cheaper the audiobahn way and be probably just as loud. I like RF stuff but why would I spend 3 times as much on a sub that isnt better(well ont enough to justify the price at least)

[unusualcivic]

true, the HX2 is grossly expensive

hehe couldn't agree more, although the bit of hair in there may mess up the acoustic wave as it tries to travel to the back of the box.

I'd get a box made of 1/2"-3/4" Lexan... the lexan would be great to build a sealed box out of. stuff is literally bulletproof, and it bends with the travel of the woofer increasing the sound quality. but the cost of the lexan makes it hard if you ever screw up.. and to make the edges clean you'd spend a lot of time with a saw, and lots of sandpaper. But when you're done it'd be the best looking box around, and with a few neons in/around it, it'd be awesome.

[Icantgetno]

Bah the new JL series would far out perform the audiobahn. When it comes to stereos spend the money to make it sound good as well as loud the first time so when you tire of driving around with massive bass and shity sound you can still enjoy your investment.
