Mid-bass subwoofer?

[the1010boy]

Hello AudioAficonado world!

I’m looking for recommendations on a subwoofer that excels with mid-bass frequencies as well as “regular” bass frequencies.

I haven’t owned a lot of subwoofers over the years but of all the subwoofers I have owned, NONE have sounded so beautifully melodic in the mid-bass as did my TANNOY PS350 that I unfortunately parted with.

Now, it's true I can find the Tannoy PS350 online in used condition (there's one for sale on eBay at the time of this writing).

However, I'd like to find a suitable UPGRADE from the Tannoy PS350 that sounds just as musical, melodic and amazing, or better! Especially in the mid-bass frequencies. Furthermore I'd like to find one that has balanced XLR inputs, which the Tannoy PS350 did not, unfortunately.

THOUGHTS?

NOTE: I own a JL Fathom F113 v1 and a Focal Chorus SW 700 V and neither blends well with my Sonus Faber Venere 3.0 floor standers, or my Focal Chorus 705V bookshelf speakers. (yes, oddly enough the "matching" Focal sub doesn't blend as well with the Focal Chorus 705V as did the Tannoy PS350 sub, go figure.) I have also owned a Velodyne V-1012-B and a BIC America F12 and neither of them could perform well in the mid-bass to blend well with bookshelf speakers, or "lean" floor-standers.

PS. I believe this is the first thread I have ever started so apologies if it’s not up to spec.

PPS. See also this post in the "Lets hear about the gear you parted with and regret letting it go" thread.
