^^^ Well actually, Z
= Up and down, and Y = front to back and X is side to side (with phone facing forward (long ways) in the seat). If phone is sideways, X and Y axis would swap.
Great stuff here
and Ray’s thread as well. Since I’ve owned and loved a Rythmik FV15HP and a Cap 2400 (the cap 4000 Beast wasn't available at the time), the differences have always intrigued me. Although my Rythmik is a FV15HP and not a FV25, my impressions compared to the 2400 pretty much echo what Tony said a couple posts back and in Rays thread for characteristics of sound sig (even Audy chirps as Chucky noticed as well).
FWIW, I don’t have Seaton F18’s, but I do run 2 UM18’s in 4cuft sealed cabs (built from flatpacks), as well as 4 SI DS4-18s in 4 cuft sealed cabs from flatpacks too. The specs are very similar for these two drivers. I ran the 4 SI’s for quite a while, then added the two UM18’s later since they don’t make the DS4’s anymore. Subjective impressions on my end are that the UM18s (and DS4-18s) sound very similar to each other, at least when added to the mix. I didn’t really directly compare them each in a A/B comparison, but couldn’t tell a sound diff when added to the mix. BUT I can say for sure that the Aydy chirp sounds the same on the two and very similar to the FV, with the 2400 sounding way different and not as high pitched as noted from all of you guys already.
Where I’m going with this is, from my subjective impressions of these subs in two different rooms, I find the sealed UM18s (the same drivers that the F18’s use) and the DS4-18s are kind of a combo sound sig of the FV and Cap. Full and weighty in the lower registers more like the Cap, but also a little cleaner/articulate in the upper registers/mid bass area like I found the FV to be. Which makes me very happy, because I loved both of these qualities
I would have probably gone with all Rythimks or all Caps but needed 4-6 subs and a cheaper way of getting them. Fortunately, I love them, but was a bit nervous going this route, as the Caps and Rythimks are amazing subs!!
I shared some of these thoughts as well in Ray's thread a while back I believe, but thought I'd share a few impressions again for another perspective on these subs (although not the same model FV and Cap, but probably still sound very similar). Again, great stuff Chucky and nice FRs!! Pretty awesome to get to have all those subs in your room at once ...a sub lovers dream
