You know I have NO idea how they do what they do but I came lastly from Fritz Carbon 7SE that are spec’d at 38hz.& in my room & system the 30.1’s are as full,deep & tight as the Fritz but have an edge in tonal purity & slay the Fritz in low level resolution & detail retrieval..Despite specs, an 8" woofer in this size cab should make decent bass & I have NO desire to muck up mine with any sub!I will also say that in all the years and systems I’ve had,never heard rock/blues/jazz bass with better tonal resolution..I mean in the right recording you can not only hear into the steel string but deeper,down into hearing the sound inside the string bends as the finger slides over the peaks & valleys of the string winding itself!It does however take a superb recording to hear this kind of resolution & detail but if it’s in the mix the Harbeth will let you hear it..
Again how big is your room?My room is 16’x14’ & that is about as big a room as I would use the Harbeth..I don’t know how to explain why 30wpc.is enough power but I am the only guy here that has run Dynaudio’s with 10wpc.Class A..I believe it comes down to listening habits & with mine I have just NEVER had any not enough power issues starting with 10wpc.pure class a tube.....Sure there is a loudness ceiling with low power but if it’s clean at normal levels & if the amp can push current it can move the drivers & make music..Think about this..If you can get the M30.1’s for $3350.00 delivered which I think you can if seller is motivated,there is NO way you get stuck with them if you don't like or lose money reselling them and they won’t last long...Gently used Anniversary 30.2’s have sold recently for $4500.00 delivered which I think is a fantastic bargin..Don’t forget to budget for stands..I use the 24" $200.00 Pangea 4 post filled with spray in foam sound deadener...Puts the tweeter with 1"+- of my ideal listening chair height..Eventually you will want to upgrade speaker cables & I wouldn’t skimp..I’m saving for Nordost Heimdall 2 at about $2000.00 used..
