IXL 18.2.2 HT Build (10.0 cu ft 15hz)

Great work on those Gregg!! Your Statements and those subs are one hell of a combination. I showed a photo of them to my wife and she just grinned. I think that was her blessing for me to get started! :bigsmile:

Good to hear that you're impressed with the result, Gregg. I'd love to see some final pics of the room too, and keep us updated on your experiments with positioning. With 4 subs you (theoretically) have a lot of options, so I'll bet by the time you settle on something it will sound amazing.

I may have some room pics tonight, my buddy and son-in-law are coming by tonight to help me stack the subs.
I have some room re-arranging to do, I plan on building a rack in the wall for all my equipment and also install a 106 or 120 inch screen (Owen I have seen you in the projector forum, my next stop).

And Doug, I am very happy with my Statements, I still have to apply a finish on them, it will be the same as the subs. The Statements and the Mach 5 subs are a good combination. Having said that, the subs are only for movies, the Statements are incredible for 2 channel music.

Gregg, wow. Those look great. I am not sure that people can really appreciate how much subwoofer is actually there without some frame of reference, such as that door. I have one sub of approx the same dimensions - the idea of 4 makes me giggle. It is interesting how one's perspective of 'well I will never need that much bass' changes, no, evolves is a better word, as time goes on. Again, excellent work.

Maybe I'll build one more, just one more....

There's still room for another 4! :rofl:

Gregg,

Some REW graphs would be very interesting on those and maybe even a vid!!

The bass in your room is really going to be incredible that is for sure.

Also some latest pics too....


cheers

Re: Subwoofer Design Service

Are those as large as they look? When I first glanced at the photo, I thought that those were stacked washers and dryers. How large a listening room do you have?

They are as big as they look, my wife told me I was @#&% stupid when she seen the drivers, her mind has not changed but she does enjoy watching movies.

My room is 16ft wide by 28ft long and the ceiling is 12 ft high.

The subs sound as impressive as they look.

Gregg

Did anyone model this setup with WinIsd? I'd like to see it, if so!

Nice! How many decibels does adding an additional driver add? And is that if you put the same amount of power to it, also?

If the sub is stacked on top then adding a second sub should yield you a 6db increase although it could be less. So try and imagine with Gregg's as he has two identical subs stacked. I would love to see some sweeps of 1 sub then add the second followed by the third and fourth. Just to see the results.

How about it Gregg? Have you managed to run any sweeps yet?

My subs are co-located and I notice quite a big difference to my ear by adding the second sub and there is less need for EQ'ing as I get a much flatter response. The bass doesn't sound so located as it did with one sub.

I see. What happens if you run the same amount of power, but to two subs versus one? What is the gain then?

You get +3dB for double the power and + 3dB for double the swept area. Hence +6dB for two subs.

Okay, thanks!

Graham

I have not done much other than listen to the subs, I have been very busy at work, I have worked every day since mid September. I hope to touch base with you mid Feb and maybe do some graphs.

Gregg

Wicked Gregg. Are they still giving you a big smile on your face.

I look at those and think of the 80's?memorex commercial where the guy is sitting in front of the speakers and holding on to the chair.And just a thought for anyone building a large cabinet,measure the doors you have to bring them thru.a 32" cab won't go though a 30" doorway!

Hi on the behringer ep4000 what did you set your switch to on the back for sub duty as i have one but just cant figure out how they go weather they go to the left or right and and whitch one goes left and which ones go right. Any would be appreciated
