Default 4x 15" IB construction

Here's a first pic of my most recent project--a 4x 15" IB sub for a friend's new home. He's not really into audio, but wanted a decent HT setup in his living room, so I talked him into the IB. I expect he'll be pleasantly surprised.

It's located in a built-in bench along the wall to the left of the HT. It'll be a really slick install with nothing visible above (unless grilles are removed) and nothing below in the basement where it vents. Total cost including 500W plate amp with PEQ: <$500.

Very nice implementation - I bet it'll look great when it's all finished.

Are 2 of the drivers going to be mounted 'magnet out' to lower some harmonics ?

Cheers,

Rob

Which drivers are they? Are they the AE Speakers IB15 that are based on Lambda Acoustics parts?

That's the plan.

I wish, but not for a <$500 budget including a $250 amp! We're using 15" Kicker autosound drivers that have quite good specs for IB and cost us half as much as the AEs.

These are an earlier version of the Kicker Comps. 18Hz Fs, 0.49 Qts, and huge Vas--excellent for IB.

People who get all bubbly about the depth and power of a 12" box sub really, really should sit for a demo of a multi-15 IB like this just once.

If that 12" box sub made the gentleman's wife fall off the bed, and this IB has about 10 times the displacement (very conservative estimate), then will 10 wives in 10 neighboring homes simultaneously fall out of their beds some late evening? I'll watch the local paper and report back to this thread.
