Just for clarification, the t/s parameters don't change much after the sub breaks in. The three main parameters that matter: Qts, Fs, and Vas, will hardly change at all. Fs will drop a little, and Vas will go up slightly. It's definitely nothing that will change the kind of box you should be using.

Cool, be sure to do a build log.

Nice, what amp will you be running to them?

3.5-4ft^3 with a low 30's tuning will work well. Unless you're running under 1kw to the pair, there's really no need to go larger. Or you can try a bandpass.

Thanks bro.

Four SA-8's going in a 'Burban. Volume: 2.75ft^3 Tuning: 33hz Dimensions: 48" wide x 12" tall x 17.5" deep

I doubt you have the room for six 15's, depending on the subs and power you're wanting to use. Fitting then in there will be quite tricky as well.

There's 2.54cm in an inch, so 2.54x2.54 gives you 6.45cm^2 in a square inch.

Take the sd in cm^2 and divide by 6.45 to get the value in in^2.

Thanks bro.

Chamber Volume: 11ft^3 Tuning Frequency: 34hz Port area: 180in^2 Dimensions: 48" wide x 19" tall x 33" deep Another box for Jonatan Uribe...we've been working well together so far, about five or six box designs now. This is for a pair of RD Sonance 18's going in the back of a Tahoe.

Or you could just look at the specs for the subs in question. Most manufacturers will list cone area, which will be more accurate than simply taking half of the sub size and using that as the radius.

Yeah, I'm not sure how those short turns are going to pan out since the turns are nearly in line with each other.

Overall Dimensions: 50" wide x 40" tall x 20" deep Chamber Volume: 13ft^3 Tuning Frequency: 33hz Port Area: 188in^2 This is a dual 18" box going in the back seat area of a 2004 Toyota Tundra. The box will house a pair of 18" RE Audio SX subs.

No, the port needs to be 27" long. The port you have there is half that.

Scores are harder to get nowadays. Do that exact same setup and get it metered on a TL today, and I would be surprised if it broke a 155. Just saying...a 160 isn't as easy as throwing eight 15's in a sealed box in a truck and running(for example) an AQ2200 on it.

^^^that score doesn't mean anything since there's no way to know how the mic was set up. There's a sensitivity knob that can be adjusted on the fly and change the real score +-10db, I believe. I can say for sure there's no way you would do that on a TL with just 2200 watts...low 150's is more like it.

Why would you seal the box from the cab when you have the subs firing Ito the trunk?

Can you do three 12's instead?

Depends on what you're trying to do. I prefer to do 2-4 of whatever size I can fit in there. I'd rather do two 18's than six 12's...just easier to wire and cheaper.

Gettin' right to business, nice.

Nice!
