18" Ascendant Audio Havoc Sonotube

[its_bacon12]

Hey guys. I got an 18" Havoc (new version) and I'm planning to do it in about 12-14 cubes (undecided) to about 15hz or so. It will be powered by an EP2500 bridged so plenty of power to boot.

I will be starting it soon and will take pictures throughout the process.

Looking forward to your build. You'll need a high pass filter at 13 hz to keep the air speed acceptable for a 8 inch diameter port.

I'll have a subsonic set around 16hz as to not and give the port much of a chance to unload below tuning.

[Mike P.]

That's a mean sub for HT. What size is the room that the sub will be in?

[Ricci]

Sounds good. Post up pics of the driver and to keep us updated.

You're going to tune it to 15hz but use a highpass centered at 16hz?

You may want to rethink that strategy.

Tuning will likely end up being around 17 or 18
