Here you go. Simple build. No angles. 67.5" H X 17.5" W X 18.25" D. This Tapped Quarter Wave Pipe has a constant 8" x 16" diameter. The 15L7 has an 8 11/16 mounting depth. With 0.75" (19.05mm) stock, you have 1/16" left to clear the magnet.

You could do a front loaded horn, but it would be more complicated build. I have HR numbers, but no box illustrations for a FLH.

Nice, looked like a Lambo-just didn't recognise it. One of my customers has one-got it a year early as he "really wanted it"-should have waited as he got the old nav and audio system!. They invited him over for private viewing/drive of the Aventador (before it even had a name) as they knew he had the new MacLaren on order and it was the last week he could cancel and switch to the Lambo! Would love to say "lucky you"-but know you must have worked damn hard for it

I see this is an older thread but hopefully somebody that was involved will speak up. I have a early 2000s L7 15D2 that I currently have in a large ported box tuned to 25hz in my HT. After seeing this and another thread using these in tapped pipes I really want to try it too. I'm very new to this design. My question is would it be possible to move the tuning frequency down to 20 or 25 Hz by simply making the pipe length longer but keeping the cross section the same? And if so how much longer? I'm thinking 30hz is a bit high for HT use. Thanks for any help I can get!

You'll need to get and let us know what the T/S specs are.
