New to the forum like about a million of you all...wondering about something...got a great deal on 4 jewel cube speakers (two each) and a Bose small center...as I figured...direct hook up to my Yamaha RX-V463 ... they sound thin and high...I need the sub. So, I purchased a SONY 100 W sub from Best Buy, love it...makes enough rumble that my wife wants it turned down...but it gives great bass... to the question for this expert group...I am looking at several Acoustimass subs on eBay and find the 7 series has plain speaker wire hook up in from the receiver and out to the front R and L and Center ... will that work with the newer jewel cube speakers I have? I plan on leaving the two rear R and L alone... that is, I am not going to hook them up through anther acoustimasss sub... Thanks for any and all opinions on the Acoustimass 7 and the front 3 speakers. All the best and thanks for the reply.
