In Reply to: STACKED QUAD 57's / Speaker Jumper Cable advice needed. posted by waldenpuddle on April 24, 2007 at 10:09:03:
...decision, which way to turn with stacked Quads. Walker did make a few comments on this general arrangement. One was..."...enthusiasts like to do this with our panels and it's very good for our ledger!" (or something like that) and, "...stacking our panels creates a large line source which does no harm to the sound. You tend to gain around 3dB in the middle and 6dB in the bass".I do not recall that he said anything about parallel .vs. series connection either, Bill (you're right). No less an audio entity than Julius Futterman said that his OTL amps did run rather well with series connection, as I recall, though.
Down to tin tacks (or tin-plated silver, for more transparency :)). The parallel connection (Waldenpuddle) is going to (as Bill says quite rightly) demand much from your amplifier. Particularly current delivery. The 2 ophms point is a at a very high frequency and fortunately, there's generally not a lot of power being delivered at those frequencies in "average" music program. So, unless you have a lot of music with near-supersonic syntehsizer at high levels then you're likely to be "safe" ampifier wise. Using a valve amp will ensure a little more margin for error. SS amps can be a bit of a lucky dip for this application unless you know the manufacturer and specs well.
