Sub suggestions please


I just got a pair of JBL L100 Classics (I have seen that they are controversial here, but I love the look, and am impressed with the sound...I'm a happy camper).  They are connected to the Cambridge CXA61, and I run a Technics SL1600 with a Grado Prestige Green3 cart, and a Cambridge Alva Duo preamp, and Cambridge CD transport (CXC V2).  My sub is a Klipsch Reference Series 12", which I like, but it doesn't aesthetically work with the JBLs.   I'm considering the REL Classic 98, Sonus Faber Gravis II, or the SVS SB-3000 (I was told I could get it in a walnut veneer, but haven't actually seen that.  Walnut is important in this case).  Any seconds on one of those options?  Any alternates I should consider at $1,500 or less (I am perfectly satisfied with pre-owned)?

Von Schweikert Audio Shockwave V-12XS Subwoofer = superior

Also in 15" currently.   2025 10" version at much reduced price   At shows, sensational combined with even the lowest priced Endeavor speakers-sounded huge 

These are high end subs that do more than the typical sub.  Based on the speaker line (I have 15" subs with the same new Foundation 1000 watt Class D amps in my VR9 SE Mk2 as the upgrade).
