Okay the short story is a couple years ago I built a great ported box centered around a tempest X2 driver. The box turned out fantastic and I stuck a 15" driver I had lying around. Well I decided to finish it and the tempest X2 is no longer available. What should I buy? I want something that will go really low and shake the whole house.

Dayton and Stereo Integrity are the two most popular right now. Make sure to model the driver in winisd before buying.

What is the box volume and what are the port dimensions?

Here are the original dimensions from when I made the box.
. What I've come up with is a 20x22.5x23.75 internally sized box with a 1.5x22.5x 36"port. This gives me 6.18 cu ft of volume without subtracting for braces and driver.

there was more bracing added after this pic.

Looks like you got right around 19hz tune with plenty of port area for a high powered application.

What would you suggest for a driver and amp?

The Alpine SWR15 would be a perfect fit for that box

Bridge a Behringer NU3000DSP for about 1800 watts (if you plan on 2 boxes get a nu6000). The DSP will let you set a high pass filter, and eq the response flat. You will need to swap out the fan, but a quick search can pull up plenty of info on that.

I always thought you should stay away from car subs if you are building one for your house. The amp looks good.

 

[Jay1]

The parameters of the driver determine what it is good for. The stereotypical car sub has a high Qts making it sound boomy when stuffed in a small box in the trunk. This alpine is ideal for a medium sized vented box like yours, and has very good xmax.

What would a Dayton titanic mark IV or a TC sounds LMSR driver do in my cabinet. I am hoping for a 20hz tune

 

[Michael Mitten]

The cab/port dictate the tune, not the driver.

I would imagine the Titanic would work just fine. You're only 0.75cu ft bigger than the recommended box, which is nothing to worry about. The tune of your box should be just fine for that driver.

Now for how much power it can take in that cab, I'll leave that to the experts on here.

The Titanic may be a Dayton clone of the Tempest X2, just like the Dayton DVC385-88 is a clone of the original Tempest.

Good to know. I was thinking about a 700 - 1000W pro type amp like the newer behringers the inuke series
