Depending on exactly what subs and box specs you're using, a 33-35hz tuning will work well for what you're wanting to do.

Nah, not me. This is for a guy on caco.

This box will be housing four(4) Skar Audio VVX-15 subs, and will be going in an Explorer with no rear seats. Since the customer will be using a fair amount of power, we decided to reduce the box size to 2.75ft^3 per sub in order to control the woofers better and put the extra power to use. The box is double layered all around, and a 3/4" round-over is applied to the port opening. Chamber Volume: 11ft^3 Tuning: 30hz Dimensions: 41" wide x 20" tall x 48" deep

I have done multi round ports in a bandpass. I wish I'd done one single port later though... Yeah, single port is much easier.

I've always liked the idea of having an interchangeable port, especially for a bandpass box. It also allows you to build new ports and fiddle with port area and tuning, and cheaply too.

Has anyone else done the multi-port route like this before?

This box design was done for Joshua Longfellow and his pair of DC Level 5 15's. Tons of low-end bass was the goal, so what better way to do that than with a high ratio low tuned box? The sealed chamber is 3.5ft^3, and the ported section is 12ft^3 with tunings ranging from 33hz, 38hz, 43hz, and 52hz for spl burps. Alternate bracing methods and placement has been discussed, I thus threw a couple 2x2's in there for visual effect.

Tune in the 30-33hz area. You'll get lots of low-end output with those subs and a low tuning. I'm assuming that's what you were aiming for when you got them.

Yeah, it's the foundation for a wall.

Another design for Tyler Kelley, this one being for a pair of 15" Fi BTL N2's. The box is 9ft^3 with a 33hz tuning via a healthy 37"x4" port. This will be going in a 2008 Malibu.

Get the 2" Aura Whispers and skip the need for a tweeter. Put a pair or more on each side, cross them around 300hz, and run a dedicated 8" or 10" mid on each side. At least, that's what I was going to do...

It's a '72. I do love the '66-'67 though, and had a '70 with a SB400 for a little while...it was a POS besides the motor.

This is a design for one of my favorite cars of all time, the Chevelle SS. Final volume is 2.5ft^3 with a 32hz tuning via a 12"x2.5" port. As you can see I had to create a little dead space on each side of the port to kick the volume down a little. The original plan was to do a bandpass, but there just wasn't enough room.

---- I buy them from a local company. Then I load test/recharge/load test/recharge to ensure they function properly. Either option will work just fine. Yes!

The customer wanted lots of output from 25-45hz, so a low tuned bandpass was in order. The subs being used are DC Audio Level 5 15's, going in a 1995 Explorer. Volume: 3ft^3 sealed, 8.5ft^3 ported Tuning: 40hz Dimensions: 43" wide x 20" tall x 40" deep

Depending on power, I'd do a 10-12ft^3 common chamber ported box with 160-180in^2 of port. Tune in the lower 30's and prepare to wang.

After really liking Revo1 and Revo2, I didn't like his 3rd World album...hopefully this is better.

I have a practically NIB Eclipse EQ1000 that you might be interested in. Old school goodness, looks like it has never been used.

Just curious, but why didn't you do a normal slot port?

Check out Vector chargers. I have used them for quite some time now and really like them. It's the same brand that Kinetik used for their chargers. Also, I have a big ol' Schumacher automatic charger with wheels that I got for $100 from Wal-Mart. It's does a really nice job. Basically, just look for something that is "microprocessor controlled" so that it regulates voltage and such while charging.

Who wants to build a sealed box for me, I'm too lazy right now.
