dlcockrumYes we did. After a side by side comparison with the owners of a Velodyne DD-18, JL Audio F-113v1, and a REL Studio III, the REL's propitiatory speaker/high level connectivity greatly restricted its location within the listening room and affected the imaging of the main speakers.
Did you use the hi-level input (mandatory IME) from your amp to the Studio III in your auditions?

Feeding the REL a processed low level signal from the DD-18 removed it from the speaker chain which also allowed for better room positioning and improved its performance a great deal. Even so the other two subwoofers clearly integrated better and provided a more robust well defined presentation in this particular room.
artemus_5 OPMy only experience with REL was with our little comparison. The cabinetry was very well done and may have accounted for a large portion of its cost of manufacture but I couldn't say for sure.
I have considered adding a second Storm 3. However, the price they want is near to what I can buy a new SVS. And, the Storm is now 12-15 yrs old. IOW, its old and ready for service or retirement soon. So I am hesitant. However the storm does integrate very naturally. And I use the high level input as per Rel's advice.
As I mentioned above installing the Studio III using the manufactures preferred high level cable connection affected the imaging of the main speakers. The affect was slight but noticeable to me. We used long runs of economical Blue Jeans low level RCA cable in the comparison and Cardas Golden Reference speaker cable to the mains. I've read after market cabling may improve its performance.
You might consider slaveing your Storm from your choice of a newer subwoofer.
Extra low frequency performance is very room dependent. Add in personal taste and the amount of setup involvement make any subwoofer choice a very personal one.
