Don't know how to ask but I want to make a set of new boxes. Therefore I am in search for a few good woofers. The ones I found end up in some enclosure of 150 liter or so... Can be a bit smaller. then they cutt-off earlier. Now I think of placing 2 smaller woofers in 1 chamber, but what to do with the TS-params. Add the VAS, Divide the R or Z0 by 2 or multiply... ( Chassis should never be in serial anyway ) then the other params... ? You could put even different chassis parralel... But then how to calculate or simulate ???? if even possible. I found a lot of documentation but never found any info about what to do when you put 2 chassis in the same cabinet. It is a bit expensive to just buy and see what it does... So I want to calculate a bit and simulate also in BoxSim For some reason 2 chassis can pump up the lower range of the spectrum, and thats my goal. I want to go as low as reasonable, 30 Hz at -3dB or so... Most systems I tried grow to large boxes... Too big ! For example, my old Visaton WSP21S does produce the low organ sounds, but it could be somewhat louder. They start falling off at 40Hz. I think the 30 Hz is there almost at -10dB [ When you start the falling-off at say 40 Hz, then there is plenty of choice... Same for comercial systems, the most expensive are better and go to 30 Hz or a tiny bit lower... ] All the links to some documents or maby Knowlege you want to share is welcome. Until now I have the Idea my goal is too ambitious, and those low sounds are making only standing waves ? So it might even better to forget it ? I have no experience with that !
