Folded horn sub for a Klipsch Heresy

The 18" BR bin was a freebie from a church. It's being powered by the Yamaha HTR-5730 on top. Basically, the Yamaha AVR is a 5 channel subwoofer amplifier now. Can you imagine if I had 4 more 18's!

How do they fare for home listening ? I think I saw a review for RV's big amp at ASR.
I went with PA speakers because of the good reviews of Behringer 15's and Mackie 10's on avsforum.com. I figured why not try some 8's. They were $92 a pair at the time, so I bought 4 pairs and converted my Onkyo 7.1 HTIB speakers to the Rockville SPG88's for 5.1.2 Atmos.

I needed to upgrade the basement 5.1 speakers, so the basshead in me went with the 7 LyxPro SPA-15's at $99 each to upgrade to 7.1.

My son has my Onkyo 7.0 speakers in his apartment. The Onkyo 10" subwoofer is in his bedroom 5.1 system in our house.
 
Gee - hope you're feeling better.

I've couple o questions on the 30Hz PT12 pipe.



The 3"x 12.5" mouth is at the very bottom ?


How about the dividing panel - should its backside start 6 inches from the inside rear of the pipe? What about the top of th divider - will that be ~5" in the top 3 spots ?

A positive flare makes the enclose bigger for the same tuning frequency.
Probably a 3-6db gain. All you have to do is swap S1 with S4 or S5 > Loudspeaker Wizard > turn on the auto segments and see the gain.

Actually, a single fold straight (zero) flare is the simplest TH enclosure to build. No angles!
