The THX electronic XO's settings that have been widely adopted set up for a 24 dB/LR4 acoustic alignment of sealed mains and subs at the XO frequency, but that is rarely the case in practice.
I am ready to purchase a pair of ported speakers that begin to roll off around 80 Hz, the CHT SHO-10. There will be no high pass XO to these speakers, they will roll off naturally. They will be paired with sealed subwoofers that use a variable 4th order low pass XO.
I have ported B&W 602S3 now. I am auditioning the sealed GR Research N2X full range and noticed that the low bass from the subs more refined with the N2X, subjectively. Which raises these questions.
1. This is a 2 channel system. What type of issues, if any, with blending the outputs of these two disparate designs can I expect? I understand that there can be problems, but it is done in many systems, albeit with a high pass on the mains usually.
2. Modeling shows that a sealed design of this speaker in this enclosure size will raise the roll off to 200 Hz, not something I want to do. Is blocking the port going to give this same 200 Hz roll off?
