Dual Rythmik F12G's paper cones should do nicely or check out the 15 inch offerings.

Thanks for the suggestion. Those look great! And seem promising. …especially the 15” variant. :yes:

Try Craig’s set up methodology. Then get a second sub of the same variety. I am less worried about which sub model than the placement, set up method and then two - which I find to be much much better than one.

Absolutely :thumbsup:

It’s all about equal pressurization.

Yes, 2 is better than one. Especially if you have the JL Audio CR-1 to aid in their setup.

130hz way too high

Agreed, the highest x/o point I use is 40hz. The majority are even lower.

I also agree that 130hz is way to high for the Fathom. I feel the Fathom’s best work is done below 50hz. Or as suggested here, 40hz.

Which is why it pairs so well with my B&W 800 D2. Because my 800 D2 produce all frequencies well even down to 40hz. Whereas my experience with the Venere 3, no matter how I set them up, still lack volume below 100hz.

So, asked another way, my original question could also be…

What can I do to get back the lost mid-bass & bass frequencies my Sonus Faber Venere 3 aren’t producing that my B&W 800 D2 are? (when compared as 2.0 channel systems, both systems without subwoofers)

Unfortunately, upgrade.

Upgrade Veneres or add a second sub and JL Audio CR-1 crossover. Locate the subs next to each speaker and integrate from there.

I have no experience with the Venere but am not sure why they have so little energy below 100Hz.
