Thanks for the advice, I seen that lower wire gauge has better signal and can go further without quality reduction. The Kenwood speakers served me well a few years ago(last time I had these set up) and I figure Kenwood is a good brand and the wattage and such are not bad even by today's standards, along with the fact the receiver uses 100W/8OHM as one of its standard.
The Wireless sub I read in at least one place has a crossover frequency of 80Hz, and the receiver has several to choose from, and 80Hz is usually the standard. The sub also uses 2.4GHz wireless(and from reading around can also wire like normal and NOT use the wireless function if I choose...), it is a down firing sub(heard these are good), and has a frequency response of 36Hz-250Hz.
I am somewhat almost second guessing the sub, but will test it to ensure it sounds as I would like, as there are other options in the price range. I know Wattage is not the most important factor, and I have seen it can only do 30W continuous and peak to 70W, so I don't know if it will be enough bass, but may be plenty for the room I am putting it in and to be honest, my fiancee is not a big(hates it really) fan of thumping bass, so may just be perfect. The sub will be here Friday, but not sure if the receiver will be(bought from two different places).
One thing is for sure, I am not the patient type of person, and the anticipation is killing me lol...
