Greets!


Baffle F3 = ~4560"/width.


Loading woofers with markedly different specs, especially WRT Fs, in vented alignments can have one 'hogging' most of the power, making the other little more than a 'slave' unless tuned to the higher of the two or in some cases the mean between the two.



All things considered, load all the 515s in the 8256s and the 416s in the 8154s and some/all [re]tuned depending on the app[s] with the 515s limited to 0.707xFs if necessary to get them down to the 416s for 'fill' or maybe make the 515s the mains with the 416s as 'fill'.
