which sub(s) for my home theater

but will there be an audible difference tho?

Again, too vague a question.

We need to factor in the net sensitivity of the four 8" drivers as well as the mechanical stroke.

Four correctly chosen 8" drivers could easily outperform a single 15".

Thinking back on his budget, he'll probably be better off going with a single 15".

well its going to be 75% movies 25% music 15" is more then likey going to have a lower Fs with would suit a HT application better

Go with the 15" you will like it quite a bit more for movies.

i forgot to add this is going in my living room area wich is around 12.5x13 but its a open floor plan so dining room and kitchen are kinda in the area no walls to close in the sound from the sub

If you go with a 15", you should seriously consider this driver.

It has lots of copper in the motor (low inductance, low distortion), it's efficient, and it digs very deep. Works well in sealed enclosures and does even better in EBS enclosures. We're talking in the teens here. At the price, it's a no-brainer.

cone area;One 15" = 176.71

Four 8" = 201.06

Thank you.
This thread was hilarious.

Neither of you get it. This isn't car audio where there isn't important information down to 10hz. Cone area alone is merely a part of the equation.

Both of you DO get it. Thank you.

The titanic 15 is a far better driver. I own both, and in my HT enclosure for the titanic, it simply defies belief.

PV is right, mostly for movies you are waaaayyy better of with a larger driver with a lower fs, than more cone area with a high fs of like 35, its not car audio, its a bit different

Precisely. When you want to reproduce some Jeezy in your Wrangler, then 4 8's is a perfectly reasonable solution. When you need to FEEL dinosaur steps and the cloverfield monster throwing the head from the statue of liberty, the 8s simply cannot keep up. It's down to the mechanics of what it takes to produce that much output at that low of frequency, and if your Fs is too high, all that's going to happen down low is that you'll either end up bottoming out OR you'll just get garbled noise. A 15 or 18 with a sub 20hz Fs is made to produce large amounts of linear output down at those frequencies and when coupled with a large ported enclosure simply cannot be beaten.

Consider 1 15" Sonosub.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Cheap to build and you get to contact the local concrete supply company.

I can't remember, it's a 27" cube with a baffle height port, tuned at 15hz aka the port takes up a good amount of room, but it's over 6 cubes still, I do remember that.
