i dont tune that low. i never listen to anything that low. i keep tuned 41 hz. it plays down to about 35hz this way without sound like shizz. and plays above just fine

if you say so. my box actually plays 31hz pretty well if im conservative with my gain. 90% of time riding around i dont go over 1/4 gain anyway....

I usually play at pretty low vol just bumpin around town too. In my xfl box my port ran into the subs so I had to do a shorter port and it was tuned to 39hz in the end and it still hit the lows pretty decent surprisingly!

8.5 - 9^3 net, 20^2 port per cube, tune to your preference...

Subs up/port back in the middle usually works well.

Ok so i re measured and figured out that my box is about 9.6 or 9.8 cubes. So it is a bit large i think. And i also only have 2 6" aeros so im pretty far under the port area i need.

You where say 8.5 - 9.3 cubes net. I have bc3500d, so i think im going to bring it down to about 8.5 cubes. I tested my current box last night and i could get over like 147.6 or so. I kinda expected better numbers but i its a poorly designed box

Also this may be a noobish question but is net before or after displacement?

NET is after all displacements.

With aeroports you can "generally" get by with about 1/2 of the port area you would with a slot port. If going for numbers you don't want to choke the subs though.

Where is vehicle peaking/where is box tuned?

Crap thats a huge box. And alot of port.

My vehicles resin i believe is 53hz
My box is tuned at about 41.5hz and is peaking 42 on a sweep

aq.s need a ton of.port to begin with vs. other subs but when ur chasing numbers ur gona have to let it breathe even more

9 cubes net. 33 hz tuning sounds good on xfl's imo. They will play low. No offense, you've got more of a fart box setup. You will feel a tuning of 33 hz more in your body with those lows. That transfer of energy, I love that ****.

my current box specs are 8.8 cubes net @ 38.3Hz, with only 56.6 square inches of port(yea i know i need more port area). i remeasured yesterday and figured out that what i put on here in my sig was a bit wrong. i keep my tuning around 40 - 43 because i usually dont listen to nothing below 35hz, thats just my taste i guess lol. i actually tested the other night but the current box is poorly designed, i was only able to get 147.8 from it on music, which it made me mad at first but then i took into account the box is not really a good design and also i have WAY to little of port for the box size. i tried burping but my music score is louder then my burp, idk why that is but it is. yea sometimes i do miss having more low end but like i said i dont listen to alot of low freq stuff

I like to play full volume at no higher than 25 hz. My last box would play the teens. With authority.

And still reach 60 hz.

You need to be peaking in the 50's then, more port area and higher tuning if numbers are what you're after...

Yea... I know port area is a issue. I only have a total of 56 square inches of port. So i know that will be a pretty big gain. Also bringing up the tunning for comps. But i guess for daily im going to find a plug and plug one of the ports.

He said numbers and music. So when I want a box to play music, I don't want my bandwidth limited. Let me design him a box and we'll see what's up.

lol i dont have a problem with band with. my box right now is tuned to 38hz. it plays all the way up to probly 56-60hz and play down a bit. i just never really listen to any thing lower then 35hz. i joke around with i love you girl which is 31hz from time to time but that about it below 35. my 2 big issues with the current box are i dont have enough port area, and the box is to deep meaning its to close to my hatch and the low port area and lack of room to load off my hatch is probly choking the subs.

i cant actually post a pic. im at work.

Subs up & ports back
2 8" aeros
45-ish Hz
9.22 cubes net

External Height = 23 in
External Width = 40 in
External Depth = 23 in

yea i know its better then what i have now lol... if my box wasnt so deep i would just change the ports. but its to bulky. i know i will see a gain just from port area. and we rearranged some stuff and moved my batts out of the cargo area so to make so space, then moved my box off the hatch like 3.5 inches & hell just doing that gained my .7db.

Do you still have back seats?

Buck
03-26-2013, 05:23 PM
Do you think you could fit a single 12" sonotube and glass it? That'd be sick. It's about 113 in^2 port area where the 2 8's have about 101. Just a thought.
