Im wanting some input from anyone who has done a few or a lot wall builds. I am soon gonna be re walling my 02 Ford Taurus with 4 L7 12s I was not happy with my 4 Pierce Audio WMD 15s that I just ripped out, they were very musical but didn't really push air for ****.

Im wanting to know if there is a better place for port that will push air better while still maintaining descent sq? (Beat for beat you know).

As of now my box is 2 separate ones that are 5.763 cubes after sub and vent displacement. They are gonna have 67.5 inches of port per pair(kicker recommended) and is tuned to 32hz. Ports are gonna be located on the passenger side. Unless told to do differently the whole point of this post. Also looking for someone with a long history with solo-baric's, cus If a diff amount of port area is recommended im only gonna listen to someone who has a history of builds with these subs.

Advisement? Is that even a word? I don't even think Dubya could make that up.

obviosly not to scale lol (drawn very quick) but you get th idea build two side by side boxes with ports @top then face /beauty plate over both http://i668.photobucket.com/albums/vv50/DAPPA5/taur.jpg

I see, and you have had better luck with air movement that way?

WOW!! You would think by as many post you have put up that you would have learned not to post dump.

And yes it's a word look it up if you have to smart one and gtfo this thread unless you have some input on the topic at hand.

Were are you looking to get the air moving?Are you lookin for hair tricks at the widow or are you just wanting to move alot of air?

Hair trick at the window while still maintaining a descent sq satisfactory level that suites me if you get what im trying to say.

I would say it's more a matter of box tuning, song played, power level/subs vs port placement. I've always read that port on driver's side meters the loudest though.

I did 4-5 walls a few months ago, some port in the center, some on driver's side. I believe they all do hair tricks...

The box may be alittle small but I would run port on the driver side.Get as much port area as you can and shrink it down till you find the tuning you like.

See I think my 4 15s didn't do a good enough hair trick due to the fact of port area. Even though I did the recommended by pierce.

How do you think I got so many posts?

I believe the word you were looking for was "Advice"

Good luck with your wall, stinky.

As of now Im looking at like 6.0 cubes flat with port along top of each enclosure they are gonna be separate boxes. And it looks like 72inches of port per pair. Tuned to 32hz.

If you have never heard advisement before, then wow. I'm just gonna quit at that!!! Have a good one.

what was net volume/tuning/port area for your wmd subs?

07-07-2009, 03:43 PM
Since that issue is behind us...

What is your goal? A loud street beater or do you want to do good on the meter? How much power are you running?

It was 7.73 cubes before sub and port displacement per pair. I had 62 inches of port tuned to like 35 hz. Sub displacement was .254. And the vent took up .7400cubes. So between the 2 subs they had 6.482 usable cubes of airspace.

Loud *** daily driver that isn't gonna look to terrible on the occasional local competition term-lab.

Around 2500+ watts for the 4 subs. 2 Kicker SX1250.1s for them.

If I were you, I'd put the ports on the drivers' side.

a) You'll at least get the illusion that they're moving a lot of air because the port will be blowing on you when its cranked.

b) In walled setups, they tend to do better on the meter when the port is on the drivers side.

I rather only do a 148 to maybe a 150 and be able to do a hair-trick passenger window side then just get the illusion.:crap:. My intention is to be loud as hell to the ear and not as much so on meter.

A hair trick with 4 12s and 2500w is wishful thinking. You'll need more power and / or more cone area. The L7s are potent woofers for sure, and I bet they could take a pair of ZX2500.1s. That would take a lot of work to make your electrical able to handle that.

I don't think you have enough port area to get what you are looking for.You need a big port to move alot of air or alot of cone area.I would build a new box common chamber port on the drivers side.With 160-175 sq in of port area and 12-15 cu ft of air space.

I have the electrical to back 7k. But i just wanted to run the SX's cus I love how you can control them from the front of the car but. 4 L7 12s is barely a hundred inches shy of cone area from 4 round 15s.

I have seen a few car's due half *** hair tricks with 1000 watts on a pair of 12s. So I know I can do it in a wall for sure.

That was my reason for asking on where port placement should be. Because if there is a place to put the port for better on a meter then there has to be a place to put the port to push more air. RIGHT???:crap: At least im hoping.

Yeah, the SXs are nice amps for sure. I'd say a slightly oversized port on the drivers side would be your best bet.

Thats alot of port for 4 12s don't you think. That will prob sound pretty muddy and not very musically accurate. I would think.

My biggest concern is the suspension of the L7s with that kinda air-space and port area.

I had a 15" L7 in 4.5cf @ 34hz and it took 2000w on music no problem over the period of 6 months or so. I sold it and it was still in good shape. I think they could handle 675w apiece no problem, even with a large port.

40 sq in per 12 is alot of port?

I agree, I was saying don't you think that will be a little excessive??? Even though they are not gonna see an *** load of power.

I don't think 3-3.5 cu ft and 40 sq in of port is alot.Last box I did for my 2 12's had 6 cubes with like 75.

I know they will handle the power im just worried about unloading them with that kind of airspace and port area.

I had an audioque 2200.1 on a single CVX 12 for like 2 months the coil didn't mind but the suspension hated me.:laugh:

As long as you aren't playing way below tuning you will be fine.A bigger box is more effecient.

It had a decent transient responce.But I do listen to mostly rap so a little bit of muddled bass didn't bother me to much.It did move some air though.

seems like your box for the wmd's was way underported and could have probably been bigger, given your power level.

good luck on the new build and post up some results or hair trick vids...

jmanpc

Always figure 12-15 square inches of port area per cubic foot. So if you're going to have 3 cubes per sub, look at 90 sq. in. per pair.

I agree funny thing is, is thats what Pierce told me to use for the airspace I had.
I was running a Cactus 5k on those subs at 2ohm then so I was prob seeing 2500 to 3k out of it. But yah the WMDs only have a single spider, so Im assuming thats why they recommended the port area they did so I didn't completely ruin the suspensions.

Also wanting to know what about a 4th order bandpass. Or would I have enough airspace to do it and would it give me better results for what Im after. Looking at 33 tall 39 wide and 26 deep.

Walled_Taurus
07-20-2009, 02:45 PM
Alright things changed up. Im gonna have much more power running in the end when Im done. So if I have like 8k available for power would you run the 4 L7 12s or 4 round 15s. The airspace is gonna be like 3.5 per sub for the 15s and the maximum for the L7s.
