Double Your Subs (without changing the pattern)

[@Daprovn]

you are a great engineer, i have used a lot of your knowledge for my work. sincerely thank

[@mippymoo069]

thank you so much for explaining everything in all these videos your videos help me make sense of what i am doing . your a great guy

[@chungtran5513]

I love this design, hope to see more videos. I have a question if I put multiple speakers together and want to open the angle of 120, what should I do

[@nathanlively]

Hi Chung, can you share a photo or design? I'm not picturing it.

[@richm1981]

Which software are you using there ? Thank you

[@nathanlively]

MAPP 3D?

i have some danley th812s that have enough drivers i don't think merlijn's formulas will work --- can i just empircally measure the acoustic center by using two microphones on a big flat outdoor field rather than esitmate from the baffle area?

[@nathanlively]

Sure. Just like in the video. Mark the center. Two mics, equidistant. Move the sub until you get matching phase. Find distance away from center. I think that should work.

[@forest-bass]

@@nathanlively thank you! the main difficulty will be forklifting it out of the forest into a field :)

[@andreasfurtner9152]

which direction is thing playing?

[@nathanlively]

Hi Andreas, can you be more specific?

[@andreasfurtner9152]

@@nathanlively let me watch the video again, once i have power back. Maybe i got confused. However, my concern was that, working in free field with the subs, and the configuration you put them in... wouldn't you create a Cardiff, lobe of some sort, which then should be directional? Anyway let me check it again in a bit. South Africa has challenges with power and hence internet connection .(because the batteries from the towers get stolen). I love and enjoy this country, you always feel like a pioneer of sorts

If I send stereo signal to two subs (one gets left signal, second gets right signal), can I use them in cardioid inline array? Will setting all low frequency instruments in the middle help? With one guitar and one bass I tend to let them be 30 procent left or right

> Will setting all low frequency instruments in the middle help? I guess you would need to define what you mean by "help".
