Dear xx 

           Follows are my reply.

           Enclosed the driver pictures of tall speakers U3 and X. The photos I took is not very clear. Hope you could see.

           For HDTV, itself includes HD-decoder, so itself could receive TV signal. Totally the function of HDMI have three sides. The 1st is receiving TV signal. The 2nd is memory like USB/SD card. The 3rd is playing HD-DVD.

          So if you only want to play HDTV, you don't need input HDMI to Subwoofer. But if you download something by use of moving hard driver, and you need to play or see them by HDTV. Or you want to see something(movie etc.) by HD-DVD, you need input HDMI to Subwoofer. So you decide you need or not according to your market requirement.

           Also enclosed the layout color carton which you were interested in as your referrence. We just make a brief. If you confirm you like this style, we will modify with you in details once receipt your order. Meanwhile, I would like to let you know the original photo is more than 55MB, very large. It could not send by mailbox. So you see the conpressed photo only 1.66MB.

           Best regards

Dear xxx

         Thanks for your questions.

         HDMI is the latest technology now apply into home theater. Itself means High Definition Mutimedia Interface. Similar like usb/sd card, but some differrent. HDMI could receive TV signal, after pass through decoder,then make high definite effect of  TV image. As we know, most people from Europe and America have HDTVs, they require home theater have relevant function (use HDMI).

         As for usb and sd card, it just has the function of memory, but could not get the TV signal.

         Nowdays, the products which have double decoder could add HDMI. Taking our HT-8900 and HT-8800 for example. Its panel is suitable to be with. The cost is US$18.

         Any questions, pls feel free to let me know.

         Best regards
         Sabrina
