Single 8" or 10" Tapped Horn that can play 20-80Hz

[maxjr]

I've searched around and read every thread I could find on tapped horns. I haven't found a build utilizing a single 8" or 10" (preferably an 8") that goes down to 20Hz and plays decently up to 80Hz. I'm looking to build 2-4 of these enclosures to minimize room modes. I'm not concerned for extreme SPL for but rather extension, excellent sound quality (low distortion), and a slim enclosure design with 10-12" in width.

Does anyone know of such a design? I'm open on Length and Height measurements as well as any speaker. Thanks in advance!

not exactly what your looking for but close, uses a 6.5" driver down to 25hz and slim enclosure. I use four in my bedroom.

How much ripple are you willing to accept within your predetermined passband?

The Exodus Audio "Anarchy" woofer is a wonderful choice for a tapped horn of reasonable size. It's also an excellent woofer that outperforms just about any 6.5 driver in use for 2 or 3-way speakers. Great sounding, low distortion with SOTA XBL2 Motor and phenomenal X-max!

Thanks, radman12! I actually have ordered 2 of these and they are in transit. I'm actually looking for my next build. Possibly a bigger box with a larger speaker that plays lower and louder.

I would like it as flat as possible. I'm currently considering the Lab12 TH build seen here: Lab12 - Tapped Horn - This is an ideal build for me, but I would prefer a smaller box so I can build multiples of them and place them around my room to reduce room modes.

It looks like a well built speaker. I can't wait for it to arrive and listen to it.

here's a couple with some economically priced MCM 8" subwoofers. With a steep 4th Order Xover @ 80 Hz, I'm thinking they should turn out decent. Both are about 80L.

Your freq. response graphs look good! Do you have any foldup diagrams of these simulations?

[OscarS]

unfortunately no. I haven't mastered the art of the whole CAD/Sketchup thing yet. I'm thinking about picking up perhaps 4 of those MCM woofers myself, and trying them out. The parameters look great, with the exception of the Fs--too low for an 8" IMO. Nothing a thin layer of silicone on the spider won't fix though.
