This acts as Mic not as a woofer mic
I have been using a woofer (speaker wired up as a mic) for a long time. I also use a u47 fet on the outside of the kick as well as a mic on the beater inside the kick. I bought this to replace my ns-10 speaker I rigged to use outside the kickdrum. This mic seemed really well built ans stable. A big plus for me. This is not a woofer mic but a actually mic you are meant to use for the entire kick drum sound. So, this maybe good for live sound but it really has no purpose in the studio.
