sorry,don’t understand what “newly developed front wall relections” means,can you please explain!By increasing the length I mean increasing the length to fill the room width.
By placement I mean moving the SBA further into the room and use the newly developed front wall relections for smoothing out those nulls if needed.
Use this formula to ad another twoIf you are using full 2-dimentional SBA then you have all this covered.
I assume the old SBA of (x6) UM-18 is 2 high x 3 wide
and the new SBA of (x8) Pro will be 2 high x 4 wide
If that's the case you are all covered
The enclosures you have giving you Qtc=0.5 will work fine. Those are selaed EQd subs.Calculated the sealed box volume for the LaVoce and the result is about 2,3cft net volume at Qtc=0.7,on the volume of my boxes the Qtc is around 0.5.Is this so bad,are the enclosures too large for this driver?
At that point I was assuming that you had 1-dimentional SBA - a horizontal row of 8 subs placed at the front on the floor.sorry,don’t understand what “newly developed front wall relections” means,can you please explain!
The Pro drivers setup will give you +12dB more in the 60Hz and up than the UM-18 setup.I’m looking more for the midbass chest punch, (kick,slam) I guess;don’t know exactly what frequency that is,60-200,I guess, looking to hear a kick drum like the drum solo on Toad,Cream- Live at the Albert Hall bluray,so lively as possible...
Give me some time for finishing the SBA, if that didn’t work then I take your advice to move the subs to find the best response;I understand that a good FR from the subs and the integration with the mains are the most important thing, but I took this path and must finish this to see if it’s a success or not.It does matter the theories and such, your response is your response.
