| Which pair of speakers changed your Hifi life? Sound Lab Millennium 1, a large full-range electrostatic. I bought the first pair in 1999, unseen and unheard, and they impressed me so much that I changed careers (taking a big pay cut) and became a high-end audio dealer. The first time I hea... | |

| Higher sensitivity - more dynamic sound? @deludedaudiophile, to quote my favorite line from The Princess Bride, with poetic license invoked: "Speaker design is tradeoffs, Highness. Anyone who says differently is in marketing." Duke | |
| Higher sensitivity - more dynamic sound? @deludedaudiophile wrote: "I was more thinking smart people, i.e. like what I see with Kii, as a start, will figure out some way to compensate for these effects in real time." I think you are right, though there is a limit to how much compressio... | |

| Higher sensitivity - more dynamic sound? @lonemountain , I don’t follow your reasoning. You said: "So your 102dB 1w/1m speaker may not have such good dynamics with a 20W amp if 1W= 102dB SPL then .2W=105, 4W =108, 8W =111, 16W=114dB SPL and that’s it! That’s 12dB of dynamic range. "86d... | |
| Higher sensitivity - more dynamic sound? @deludedaudiophile, There are multiple mechanisms by which powert compression can occur, and minimizing them just about always favors high-efficiency designs. This will not be a textbook-comprehensive look at the topic, and I will make some gener... | |
| Looking for speaker recommendations @rooze , My understanding (based on the works of Earl Geddes and David Griesinger) is that the radiation pattern can widen at the low end, as with a "hybrid horn" speaker such as the Cornwall. As far as which such speakers I have actual experien... | |
| Best speakers for a small room Small rooms have two issues: First, the reflection path lengths are short, and that’s bad because early reflections are more likely to be detrimental than later-arriving ones. Second, the smaller the room, the larger and more audible the room-indu... | |
| Bose 901's in an acoustically treated room? The perceived spectral balance of the Bose 901 is dominated by the spectral balance of the reflected sound, and IF the acoustic treatments in the room absorb the short wavelengths (high frequencies) moreso than they absorb the longer wavelengths, ... | |
| Two vs four subwoofers for music playback According to Earl Geddes, whose ideas the Swarm is based on, the in-room smoothness goes up as the number of independent bass sources goes up. So four subs intelligently-distributed are theoretically twice as smooth as two (and "smooth bass" = "f... | |
| Dipole speakers, subwoofers and that rear wall The ear does not perceive comb filter effects from reflections the same way a microphone registers them, so in general reflections are far more benign than they look "on paper". But if reflections arrive too early, they still can be detrimental to... | |
| Concentric drivers Doppler (intermodulation) distortion would show up as a reduction in clarity at high SPLs, particularly with bass-heavy, complex music. Duke |
