I am not familiar with the Castle 7SE, can you describe its sound and also what you would like to change about it? I am familiar with some of the other Castle models though.
Multipurpose floorstander speaker
For roomsize 15X12, I need good multipurpose floorstander below USD 700 to use for both music and hometheater. Music mainly jazz and rock. For music I'm using Exposure XXV amp with Arcam 7se cd. For hometheater I'm using Yamaha DSP A5 amp and Pioneer DVD 636. Previously using Castle 7SE but sold to make way for better one. Apreciate your advice on good floorspeaker make/brand. Thank you.
