After completing a subwoofer based around Adire's precious Shiva driver and finding an amplifier to use (an Auditec 1027) I was confronted with a the problem of finding a crossover solution for the project.
An active filter that has a variable low-pass filter (70hz – 120hz or similar), at least 3db of gain, and single ended inputs and outputs would be perfect.
I know there are many excellent designs around and building something that met the specifications would be no doubt be more exact. A commercial solution would be preferred however, time and skills are lacking.
Thanks in advance for any assistance.

I don't know about the 3db of gain, but you might try looking at the Paradigm x-20 or x-30. The x-30 has a phase shift adjustment. They can usually be had on ebay or audiogon for less than $100.
