That maybe true but the context was that it's a factor for consideration along with furnishings that explains why in the real world, room measurements often result in falling FR compared with anechoic. Linkwitz wrote an excellent series of articles on room measurement which explains far better and in more detail than I'm able, or inclined to!sq225917 wrote: ↑Fri Mar 08, 2019 12:58 pmI'd clean those pots.
To be fair I've not checked anything beyond the raw FR with measurement. I made 3 iterations of the XO and ended up going for the one with the smoothest handover.
RT60, at HF? I don't live in a glass palace mate, it's a small well damped room. No one's worrying about RT60 at HF in a domestic setting
When using in-room measurements, forgetting this often results in people misguidedly using measurement to achieve a nominally "flat" setting which in truth is actually skewed well upwards when compared anechoically. The easy way to tell is close field measurement (ie within mm of the driver) to eliminate as far as possible other effects including reflections and absorption. It's not really relevant for 2/3ds of the midband or the bass but it is for the HF when designing a crossover.
I like to qualify statements as IME of forums, not doing that usually results in someone coming out of the woodwork to throw stones (not here of course) so it's a habit that's stuck, although I don't bother with forums these days due to the amount of trolling and smart alecs (not to mention the owner of one specific forum (again, not this one!) who I won't name and shame....he makes a good job of shooting himself in the foot himself but he's one of the reasons I couldn't generally be bothered with them these days). Maybe as I'm in friendlier company here, I can dispense with the qualifications.
