The back chamber is very important...about half of the drivers energy goes back there so it needs to be strong if you don't want it to resonate.

Thanks for this link, I've studied Romy's guide and now have some more, hopefully, pertinent questions:
1. Let's say the my original back chamber from the manufacturer is a good "starting point". Is Romy saying that those last few hertz of the fine tuning of the chamber volume are very important and audible, in other words the manufacturers design may be roughly correct but in my room and with my speaker placement it's worth it to further adjust the volume, in which case the manufacturer's design may not be optimal?I am talking NOT about midbass horn here, I am talking about midrange horn 300 to 2Khz.2. Further, once above chamber volume is fine tuned, how important is the shape of this chamber?3. No mention of sound absorbing material in back chamber. Is it needed?
So far it seems like it's a strong empty box of a very precise volume...
