I've just set up a hi-fi system in dining room from kit that I had lying around after various upgrades and have a problem with booming bass. Kit is Rega Planet CD player, Naim Nait 3 Amp & Dynaudio Audience 40 speakers. The room is about 6m by 4m and has a laminate floor on concrete. At the moment, the speakers are on pretty cheap and nasty speaker stands that are pretty light. Interested in people's thoughts as to what I should do. 1: Upgrade to better speaker stands (any thoughts as to which?) 2: Mass load the speaker stands (if poss) 3: Some form of isolation under the speaker stands (if so which). Obviously the answer may be "D - All of the above" But am after the considerable wisdom and expertise of everyone here! Haven't really set a budget for this, so am happy to hear any ideas no matter the price range! Cheers!
