Hello.
Long-time lurker into this thread, now looking to build a version of these but with a 8PE21 midrange and TPL-150 as tweeter. The 8PE21 in a 12" baffle starts dropping abruptly at 280Hz and know of a user crossing it at 250Hz with a 16" baffle.
I believe I could use either 8x 6.5" woofers like XSD for a xo up to 420Hz or 6x 8" woofers for a xo around 350Hz. It seems 350Hz would fit the 8PE21, so I´m wondering about pros/cons of going with 6.5" vs 8" woofers.
Using GRS Poly Cone Rubber line as examples, comparing frequency responses of 6PR-8 vs GRS 8PR-8, the former starts dropping at 80Hz while the latter does so around 60Hz. I have sealed subs to use below the SLOB yet I guess reaching lower is generally better. 16x 6PR-8 would cost $215 vs $180 for 12x 8PR-8, so price-wise is a tie.
Are there benefits to the 6.5" that I´m not realizing or should I just go with 8 inchers?
