subwoofer setup problem


I am trying to mate an ACI Titan II with my Thiel 22. The Thiels go down to 30 hz but the lowest crossover on the Titan is 35hz. Thus, there is an annoying overlap in frequency. I am considering several possible options and would appreciate some input. They are (1) get a REL sub whose lowest crossover point is 28 hz. (2) get an active crossover and cross my mains at a higher point. (3) use a passive 65hz filter between my preamp and amp that ACI has.
The passive filter is the cheapest route but will it do more harm (to the sound of my thiels) than good?

Thanks

My Aerial Acoustic 10T's reproduce down to a stated 26Hz and probably lower. My Triad Platinum 18 inch sub's lowest cutoff is 50Hz which is the setting I use. The volume is quite low on the sub and perhaps due to it's placement in the room I do not notice any hump and is stable to 18Hz. The integration has worked quite well.

Before giving up or buying aftermarket tweaks, I would look first at lowering sub volume and then sub placement within the room. In my 13 x 18 room, the sub is about 1/3rd distance away from the nearest corner along the long wall.
