Is the input voltage 110v? I live in a country with 240V electricity, will I need a step-down transformer?

Thank you for contacting us. In regards to your inquiry, yes you can use a step-down transformer.

Would i need to use the xlr for thx or can i use a splitter for the left and right inputs? Thanks

The subwoofer can receive inputs from both XLR and RCA connections. You can split either connection type. THX is a specification that the subwoofer meets.

Why is there no shipping date when I go to check out? I would like to purchase but not until I at least have an estimated time of arrival.

Thank you for your question. Please reach out to Amazon customer service to assist with your inquiry.

I question the overall size of this subwoofer. Amazon says 20"x20"x20", but the manufacturer states the subwoofer is 29.1" x 20.3" x 23.8"?

Amazon’s measurements are not correct. Definitely not 20x20x20.
