The ERM 6.2's are quite a bit better than the Best Buy stuff or the HSU Research mini monitors...the most compelling reason for recommending the ERM 6.2's are it's performance number 1 ( 2 x 6.5 in woofers can move quite a bit of air) , number 2 the ability to change response if used on a bookshelf or close to a wall ( via boundary compensation circuitry built into the Xovers at the flick of a toggle on the back panel) and the ability to cut or boost the tweeters output via another toggle (on the back panel). You can also bi-wire or bi amp the 6.2's which gives yet another level of possible improvement (SQ wise).Overall these features make the 6.2's extremely flexible which one does not usually see (as useful practical features) at this price point.
I am highly tempted by the Ref series ERM 8.3 speakers myself and bet they would be a killer system for the cottage....then again I might DIY a pair for such a purpose.
Peete.
