Yea...ther is 4 small ones

Thanks, i don't know if that wiring configuration will work or will change the sound significantly in this speaker configuration, by reversing the polaraty on each chamber the first thing that will happen its the anulation of the passive radiators function resulting in a perceptible less bass sound, but i could try in the future to test it with a ported project

Its not true. All speakers have to be in phase.

@@Valtra103 Some 30 years ago when there was not youtube or internet I was making speakers. First time that I've build a dual speaker in one box, I ran into problem the sound was not good, by experimenting I found out that you need to reverse one of the speakers. Two speakers in phase push air in one direction, since it is a closed chamber air has no where to go so it dampens the bass-less bass from the speaker! By reversing one of them as one goes out the other one goes in- more bass.

@@MicSokol Still not true. One random experiment doesn't change physics or how stuff works. Maybe your box was wrong size, and not correctly aligned or something... Air in box acts as a spring and creates resonance, which enhances bass output. By connecting one speaker out of phase box is not pressurised, and there is no benefit from even having a box. All cones have to move together to make output. A few times i mixed up phases, and bass was gone. Do you have measurement microphone? Or anything to prove your theory? put two speaker drivers in box and measure response with correct connection and your connection. This is not even thing to debate. You wont find any books about speakers, any sources that would say reverse phase of one driver. All commercial and DIY speaker have drivers in phase. Some have 3, 5, 7, 9 drivers in one box and work fine. Which ones of three or five drivers would you reverse connect? UKposts not existing is not an argument, nor doing something for 30 years. Wrong is still wrong.

Talk about being confidently incorrect lmao
