What is the approximate -3dB bass response of the Sapphire XL with the port plugged? Also, I can't find the 85Hz filters on the website. Are they discontinued?

I'm thinking of purchasing an Anthem 225 integrated with pre-out and if so I would have to set up my AV123 MFW-15 subwoofers without the electronic crossover. This could be a blessing in disguise if I can blend them in seamlessly.

Thanks.

I don't have the chart handy, but 80-85Hz is just about right as a -3db point with ports plugged. I'll try to double check later. 

Im sorry, we discontinued the passive filters a while back . . .

If that is the case regarding the frequency response, then I don't need the filters because I want to cross them over at about 75Hz. Thanks very much, Mike!

Personally, I subwoof (yes, I'm using that as a verb) with the Sapphire XLs unfiltered and the ports plugged.  It looks like you could get similar filters here if you decide you want them:

I have no experience with these FMODs, but I'm not currently using my 65 Hz filters from ACI.

Thanks, but I prefer to go unfiltered too.

Mike - Why did you discontinue the passive filters?
