Hi Diki,
Well I'm no sound engineer nor maybe a sound expert like yourself in try finding the best sounding PA system on the market within ones budget. But I'm definitely not here to bag or criticise any company that manufacture these products, I'm entitled to sharing my opinion according to what I've heard and the types of music i prefer that goes through this systems as I audition them.
There are people that have very high regards for bose products and if bose brings sweet music to their ears and joy into their lives, then who's the expert to tell them otherwise.
Appreciate what you have, value ones opinion and expect the unexpected surprise...
Merry Christmas to you and yours, Ky
