Question 8 or 10 Inch Sub??

Hi all--Have a really quick question--mainly looking for opinions--I am only going to do a single sub in the back of the new 2.5i, however, should I use a single 8inch aluminum audiobahn sub--or--a single 10inch sub--possibly audionbahn or another brand??---Both would be in a sealed box, running about the same power--Just wondering for any input--thanks!!

a nice 8 inch will give you very crisp and tight bass hits. is it a wagon or sedan? if sedan you might just want to do a 10 because of the dampening from the back seat.

and I wouldn't recommend audiobahn. their quality has always been sub-par in my opinion.

12" is what I like. It depends on what you listen to. I like rock and rap so a 12 is better. If you listen to all rock, 10 is fine. 10's are tighter 12's are deeper. 8's well uh, unless you had a bunch of them, wouldn't sound that great in a car that size. Great in trucks but not in trunks.

depending on what sound and how much power you are looking for. there are some monster 8 inch subs out there. (well monster for an 8 inch)

kicker makes an 8 inch L7 that handles 450 watts rms
MA Audio makes a really nice 8 inch as well with 400 watts rms power handeling.

that's alot of power in such a small package.

I really wish manufacturers would make true competition 8 inch subs. imagine having 1 or 2 8 inch subs that run like 1000 watts a piece. nobody would believe what you had in your trunk. plus it would save a lot of space

good call--its all around music, a lot of all---dvd player as well, so movies too---its the sedan--i may keep the trunk center section open at all times, although im not sure---ill see---thanks for the feedback guys, ill be patient for a decent 10inch---if not audiobahn--any reccomendations---kicker squares??? maybe infiniti---ive been so into the paint for years, that ive forgotten all my "knowledge" of audio components!! Any input would be great!! Thanks all!!

8 inch is not much surface area. A 10" is actually a lot bigger. A 12" is about twice the size!

One of the biggest deciding factors in how well a subwoofer will play low notes is its ability to displace air. Just like a car piston, the effective diameter and stroke determines this. A small increase in diameter means you can displace a lot more air. It is also typical to have more throw with larger speakers of the same line or model because the magnet can be larger, fitting a larger voicecoil, and allowing longer throw while still under control.

A single 8 inch, even a good one with a lot of throw (or stroke/excursion/xmax), is going to run out of poop before it gets very loud. A single 10" of moderate quality ($75-125 for woofer only) is probably the smallest I would suggest to anyone bothering to upgrade.

Although those quoted Kicker or MA audio subwoofers may be able to (thermally) handle 400+ watts, their total output is going to be limited by their ability to displace air. 400 watts? Maybe at 200hz. But at 40hz, you're going to bottom them out closer to 50 watts, regardless of heat.

I would suggest a 10" MTX Thunder 7000, 7500, or 8000. Decent size box (~1 ft^3), long throw (usually 0.40" 1-way linear or better), cast basket, large voicecoil (2.5" ?), huge plated 5-way posts with thick tinsel leads, solid cones, durable suspension, lots of thermal power handling, great pricing.

Depending on how in love you are with the rear seat pass through, you can mount an 8" sub in the pass-through firing directly into the cabin. The 8" should be loud enough in that configuration and it will be nice and tight...

Otherwise, go with a 10". Any smaller in the trunk will lose a lot of oomph.

I have an JL 8w7 in their High Output vented enclosure and it sounds amazing. I'm not an audio expert but I've owned 10" eclipse alums, a pair of Infinity Perfect 12's and this 8 sounds by far the best. I's about as loud as a single eclipse 10" aluminum, and suprisingly nearly 3/4 loud as the pair of Perfects and sounds twice as accurate with faster rock/pop.

Unless you can get a quality 8, I would go for the 10 because you might end up wanting more if you settle for the single 8.

Check out http://edesignaudio.com/product.php?...pid=32&cur=USD, these 6.5" speakers are awesome. I have two of them in my p/u truck right now, and they pound, and sound great. The price is hard to beat. Plus, I was using them as a midrange speaker, and was told that they work well as a sub, I built a ported box (it's about 10" by 8" by 14") and two of these sounded great off of about 300 wrms. The smaller displacement of the sub does not effect the lower frequencies.

I personally like the sound of a 10" sub, its real punchy, nice bass without the trunk rumble...and Audiobahn is ok, but Kicker or MTX will really beat. Good luck

I'm trying a new option soon, I've had dual 8" under the seats, which was good but one of the speakers blew and I never replaced it.
Currently I have a higher end Audiobahn 12" It hits like Mike Tyson and it's also like having him in my trunk when I want to put anything back there.

I'm ordering a pair of Pro Series Bass shakers from PartsExpress.com I recently heard a pair in my friends Civic and was amazed. He had them mounted directly to the bottoms of his seat. No matter where you were sitting it was crisp, clear, loud and intense. Plus it didn't have that awful rattle outside the car.

Plus they're like $33.50 on closeout, just get a smaller 75 X 2 or 100 X 2 Amp and you'll be good to go.

I'll be posting up pix for this project soon.

Just a note - I just replaced 4 8's with a single Eclipse 12" Aluminum (the good one from a couple years ago) that I had sitting around. Both in my wagon, and I have to say that the 1 12 sounds soooo much better than 4 8's

Yeah, it's tough to beat 13mm on a 6.5" sub, it's a great small enclosure sub, you can make the most out of the smallest space, and pretty cheap to boot

But a w6 is atr least $350, and that's cheap, there are speakers out there for less that are as good as a w6, that take up less room in the car and hit the wallet a lot less
