Hi to all this is my first post

I have recently purchased a pair of Bose speakers without the Acoustimass unit. They are the ones sold with the top of the line systems.

I have rigged my newly aquired Bose Jewel Cubes ( supposed to be the top of the range ) up on my Denon UD-M30 midi system with a Yamaha powered sub ive temporarily borrowed ( Model YST-SW90 ).

The Bose speakers will be playing full range as ive powered them straight from the Denon. Got to be honest im not blown away by the performance. The sound is boomy at the bottom end with not much mid. The top end from the Bose is pretty good ( not astounding ) but the bottom end is awful. Can you recommend a powered sub, possibly with speaker outputs at the right frequency for the Bose satellites that will provide me with a lot more mid. I love the look of them but im certainly not blown away by the sound performance. What i dont want to do is purchase another sub and realise that its still no better! I found the Acoustimass 20 series for sale on the net for £1100 would you believe! I`d be seriously disappointed if i had paid even half that ! Ive heard the words "Bose - Better sound through marketing" on the net before! The Denon comes with re badged Mission speakers as standard ( Model SC-M50 ) and the sound is brilliant. IIRC the system won midi system of the year in What Hi FI back in 2000 or 2001 ? The speakers sound great but they dont look great in the room.

Your honest advice will be greatly appreciated folks
