On the gs thread there are some comments from the amphion rep re: someone who said even the one 15 are too bassy below their child's bedroom, so recommending they demo the 12, same top end but less bass and more focussed sound.

The One15's are not too bassy, even under that circumstance. Meh, to each their own.

I don't disagree, the guy who said that was selling some 2 month old one fifteens and asking top dollar. I actually thought it was probably the opposite, that he regretted buying the one 15's and wanted some one 18's but didn't want to say that but I don't really know  I was looking at buying the one 15 but his price was too high with exchange and shipping ect.. |

fun fact, the bigger your monitor, the better bass/acoustically treated your room should be for a performance gain, if you have a sub par room, the one12 will out perform the one15, will out perform the one18, due to the fact that they won't throw as much destructive interference at lower freq's, aka modes/antimodes. Room issues are the ONLY reason someone would claim the one15 as more punchy than a larger one18 that's properly set up and powered.

Certainly room is a big factor.
Having demoed the one 15 and 18: same cables, amp,position and room, I agree they sound different.
As these are passive radiator and both the woofers and passive radiators change in size (diameter and mass and weighting for mass), I wondered how much of the different sonics came from that, as they have the same tweeter and wave form guide ?

As these are passive radiator and both the woofers and passive radiators change in size (diameter and mass and weighting for mass), I wondered how much of the different sonics came from that, as they have the same tweeter and wave form guide ? Of course they'll sound different, the one 18's have larger drivers and cabinets, and they reach flat down to 45hz vs 49hz, those downward freqs will spawn much greater air movement in any, especially a smallish, low ceiling, even treated room, the 18's will wreak much more havoc with constructive/destructive interferences in bass freq's, more than likely having pretty dramatic nulling/mode effects from 45 to 150hz. Ex. 4-6" woofs do not equal the spl of a single 12" woof, not in excursion, not in depth of cone or surface area, the larger woof/cab creates MORE spl, in turn bringing your room more into the equation. Larger woofs move much more air than smallers in multiples/and obviously... stand alone. take the two sets of speakers outside and fire them in an open direction with nothing behind them, the one18's will have more bass, more punch more of everything down low because they are moving more air, if you have a smallish room, even fully treated, you will probably be better served by the smaller 15's because they will excite the room less, then set up a pair of flanking subs (not next to each other, and experiment to find the sweet spots) to switch in and out, fire from diff locations to fill nulls, and just switch them in/out occasionally, and if your room is sweet! monitor at 83db spl, if not lower volumes, 78-9db spl should be killer for the 1-15's in about any room with minimal treatment, don't forget that nearfield monitors were designed to take the room OUT of the equation, using them loud defeats their design purpose. |

Tony is over simplifying it, but yes a different LF driver and box will sound different and not just in the LF! Just because 2 drivers are from the same manufacturer and series has no bearing on them sounding the same in their upper region! The upper region of a drivers useable range is very important, in fact this has more to do with the sound of a system , because this is where your going to have both the LF and HF driver both working in the octaves at or around the crossover frequency.
