Single Chamber or Dual?

**3onDubs** · 04-14-2006, 11:39 AM

Which is louder? Which sounds better?

I have the option of either having a single chambered box with one tuned slot port or i can have two seperate chambers, each ported. Which is generally preferred?

Use a dual chamber box with tuned dual reflex bandpass enclosure, advantage of this design are a high efficiency over a small range of frequencies and some filtering characteristics, but is extremely complex in design and assembly.
Good luck.

Yeah, I would also go with the dual chamber, its what I have always had. With one big chamber, to me it sounds too big. I wouldn't do bandpass if you want solid bass. If you want bass to be rather tight, but still have that massive pound(when desired) go with vents. Thats my suggestion anyway.

I'm definitely going ported, but i was just torn on which box to use.

I've been doing some reading and this is what i've gathered...

It appears that with two chambers...if you blow one sub, the other sub will still play fine...whereas with one chamber, the working sub will basically be operating in free-air and possible blow.

The center divider in a dual chamber also acts as a good support for the box...limiting the flex.

With a single chamber, you only need one port and this is better for space restriction reasons.

That's all i was able to find, but nothing on the actual sound quality difference.

Yeah, that is correct. If you are a SQ buff, which from what I gathered, you are. I would go for dual chamber. IF you have the room.

Thanks Tibby....i'll probably go with the dual. I had another question that doesn't deserve it's own thread. Does a slanted-back box perform or sound any differently than a straight back box? The reason i ask is because i can get an extra cubic foot out of the triangle that the slant makes, and that would save me a ton of trunk space (my new box is gonna be pretty big).

Won't matter, just be sure to match the specs of the sub to the cubic foot or airspace, or you won't get the full potential out of the subs.

Thanks for the advice...i ended up opting for a slanted, dual chamber box with round ports. Its going to be built to spec for my subs....i'll post pics when i get the actual box.

nobody asked the most important question about amp wiring . If the subs are on the same channel u want them in a common cavity even with multiple ports. Think of it this way if you are using a single common amplifier channel the drivers act concurently as one driver.If you use one channel and two cabinets and the volumes are not exact there will be disparity in pressure on the back wave causing uneven power distribution. It gets more complicated but I believe that I have said enough. I'm not trying to step on anyones toes nor am I an expert at carputers but I have been building and installing car audio for about 16 years all the way back to my first Blaupunkt New York in 1988 ...Sorry I'm ranting anyway if you use seperate channels then dual chambers are fine. IMHO

I always use dual chamber but i usually have a dedicated amp for each sub. Im not quite sure what brill is talking about but i think its like running it in mono vs stereo.
