Q: can this unit be converted to wireless by adding some type of accessory
A: All sub woofers can be converted by spending about 60 dollars on a wireless kit.
Q: What is the impedance? not listed on the specs
A: I am not an expert in this area, but I believe a speaker's impedance only applies to passive (unpowered) speakers. The Onkyo subwoofer you mention is a powered speaker, so it does not rely on the amplifier's power. I have connected this particular subwoofer to several different amplifiers and receivers with no problems. It is a great source of base for a small to medium listening area for music or videos.
Q: Does it have a HTmi connection?
A: I'm guessing you meant H"D"MI, and no it does not. Why would a powered subwoofer need HDMI. It feeds from your source amplifier/receiver. If your source [amp/receiver] has HDMI,it passes through to everything after.
A: Yes, you should connect the sub to the amp subwoofer outlet.
A: The product is slightly smaller than 11"x18 3/4"x17".
A: No
