DIY Subwoofers - General Discussion
I may have the opportunity to swap my 15s for 18s.
I have a Klipsch THX Ultra2 system with KL-650 LCR and KS-525 rears.
The 15s are driven by an EP2500, in LLT 13Hz sonotubes. They do a good job, but there's no substitute for displacement. I would make new sonotube LLT enclosures for the 18s...
