frankmarsi Posted January 18, 2017 Report Share Posted January 18, 2017 1-18-17 2P.M.EST All this mention of ‘stacking’ is misleading. Unless done properly, it’s just a waste of time and space with inherent pitfalls and an amateur’s attempt at something more that really isn’t with-in the confines of an audiophile’s better listening perspective. Going back as far as 2004 I believe I was one of the only ones on this site to mention it as I was using four ‘stacked’ LST’s. Later on, I tried stacking four 3a’s along with two PL-400’s, my results were disheartening. Although stacking speakers is nothing new, it must be done correctly to fully appreciate it’s benefits. One notable successful stacking arrangement is accomplished years ago with Advents driven by two Phase Linear PL-400 amps, do a search and see. Here the stacking is well realized as the Advents have a more forward mid and high frequency output and the woofer is crossed-over at a higher frequency. A while ago, RoyC mentioned about the overly dominant bass that is rendered, especially with 3a’s. Of course, he is correct! First off, exact matching speakers and amplifiers is of the utmost importance and necessity. I’ve read of people doing it with mismatched speakers and woefully inadequate amplifiers, an amateur’s foray at best. This use is a sorrowful attempt at trying to increase the sound-field but, doing so only gives forth an unbalanced and inaccurate sound as a result with no more than a 3db. increase in volume if using everything as matched. Also, proper room set-up is paramount as over-powering a room may be the result unless correct guide lines are utilized and followed. Room-damping is advised and using proper sound/bass/ ‘traps’ and certainly even the arrangement of furniture comes into play. In vain attempts to ‘stack’ their speakers some folks are even using a single amplifier of inadequate power, that in of itself is a recipe for a blown amplifier with-in a short amount of time as 3a’s are a difficult speaker to drive in the first place. Using two different amplifiers of different specifications makes no sense at all!
