+1, I agree that a measurement would be useful. I am surprised that after all this time, no one has measured and posted results from the XL. Or maybe I missed it?

More likely confusing.
The FHs use variable damping to tune the bass, the design uses the room as part of the design, so any measure is only applicable to the specific build and the room it is in. Take the room out and you are hobbling the speaker. So measures are only useful to the guy tuning it in hid toom And knowing those that treasure their measures and give them toomuch creed they would take what they see and generalize it well beyond their applicability. dave

Easy to provide reults that are more ghost than useful.
When the only tool you have is a hammer, everything starts looking like a nail. dave

Well if someone wanted an *idea* of the sort of response they can get if they were to build it and if it was placed in a corner in their room at the same distance from the corner, sure it is a useful measurement. The measurement should have the details and caveats of the placement. My question is also about how so many builds and yet not a single measurement.
I guess it comes down to there are two kinds of diy'ers: those who do and those who don't, measure that is. I won't ask anymore in this thread because it seems no one is the least curious what the typical corner placement and xx grams of stuffing in a speaker measurement is. I just want to know where the bass corner is, and how it rolls off for a *typical* 3 ft away from each wall at 45 deg corner placement. Similarly, do we ever listen to a speaker with our ears 0.5m away? No, but that measurement is great for reducing the effect of room modes, and allows a characterization of the cabinet and driver's intrinsic ability. I appreciate all the measurements that Bob Brines provides and think more people should do the same. |

Yes, understood but I think somewhere in between would be a good solution - to have SOMETHING measurable to go on beyond, 'Better bass slam than FH Mk3..." For example, one can say, 'In my room of 15 x 20, and 12 inches from back wall, I measured 35hz at 3db down....." Something like that to just at least give a basic sense. If someone says, 30 hz, that will give a different sense if someone says 40 hz.
All speakers, no matter what do interact with the room - perhaps the FH more, but that is still something true of all speakers. UL Quote:
