Long time reader, first time poster. I like the Big Bad Woof. I think it is sealed? Please confirm. I know it has to sound top end musically. How does it fair on HT? Im looking for a little something that will perform double duty. Music first, if you catch my drift?
Not expecting big, big results on the HT end, but at least do justice.
I have read alot of your posts after seing your design. I like the way you think in terms of sound. I share your train of thought.
Dan, would you mind a little talk back about your design?
Thank you much.

Go one notch up. A sealed RSS390HF, the 15" version. The sealed response is a bit deeper, and the extra surface area will offer a lot better performance for HT.

You pretty much have it down. It is sealed, 1.8 ft^3 with 1 lb of AcoustaStuff. It looks bigger because it is not a pure cube and because I have a separate chamber on back for the plate amp. I think it works great for HT -- it gave me everything I wanted on Mr. and Mrs. Smith which is my new favorite HT testing movie because of the mix of music and explosions etc. It is powerful enough for me, but if I had it to do over and had the bucks, I would go for 500 watts, not 250.

I can't comment on Pete's suggestion for the 15" because I have not heard it, but his suggestion does make common sense. Depends on $ and room, it seems to me.

I do like Pete's response. Your right Dan. It does make sense. But, it seems to lead more toward the HT end, as I have always thought a smaller woofer= more accurate speed for music.
I did assume that you had the plate amp sealed off from the rest of the enclosure. Why leave room for error.
More amp power? Would the enclosure shape change? Could I still use the same design and just incorperate more power?
P.S. I love the fight seen! I have 6 bass shakers in my couch. 240 W/plate amp. 3 in series, 3 in series and wired parallel to the amp. A whole new experience in movie whatching. The real " best bang for the buck"!
Square off Dan. The 15 vs the 10.
....and thanks for your and Pete's response.

I do not think the box design would need to change, but I would not want to lie and claim to be any power handling expert. I would not really want more power to go louder, but just for more headroom. Mine is up to about 60% volume for music and closer to 75% for HT -- I'd like a little more room on top if I could. Maybe greater experts than I on the dynamics of power handling will help.

Gentlemen,

I have always found that finding the perfect double duty sub is very difficult. My own opinion is to use 2 subs. I prefer a 10" sub and an amp that will have a boost on the extreme low end. That way, you can have the speed for Music and the rumble for HT. It may not be practicable for you to build 2 enclosures and buy 2 amps, or one really big amp. Another method I have used with good results is to use a 10" sub for Music and a 12" or 15" for HT. I suspect that Dan's Big Bad Woof would be an excellent choice for a double duty as that was a design goal, but Pete's suggestion for a 15" in a sealed alignment would also give good results.

My 2 cents.
