    Hi Dome,

    I have been re reading this thread.
    Have you done much since post 201 and 228?

    You comments around careful and often exacting adjustment of the S9900 location make perfect sense and that should be a sticky for anyone setting up a loudspeaker system.

    You mentioned an 8 attribute adjustment.
    But the constant not discussed is the ceiling to listening distance or floor to ear height unless l missed something ?

    Have you tried different chair heights?
    Elsewhere we have talked of moving the ear height down for the systems using the 2308 lenses but l wonder if you have considered a lower chair height? That impacts on the response in the crossover region of any loudspeaker.

    The other impact is unless the ceiling is high it’s often a large flat surface less than 2 metres from your ears. A proportion of indirect sound will be reflected from the ceiling.

    I am enjoying the scale of significantly higher ceilings at the rear of our new home. The consensus is that brings something new to listening experience in terms of the acoustics.

    looks like $30 well spent (LARSA add-on)
    Direct Link -Loudspeaker and Room System Analyzer app (LARSA) is an iOS app that can be used to accurately measure the frequency response and Energy Time Curve for a sound system.
    Use LARSA for adjusting EQ for a recording studio control room, home stereo, home theater, or car.

    Ian, always good to hear from you!

    The biggest change of course is the venue. The second biggest change is moving from a "basic" bi-amp to active bi-amping through BSS Omnidrive units (tuning courtesy of "Have Laptop, Will Travel" grumpy, the ears of George and Shane, and GT messaging).

    The K2s are now in a 12,600 cubic ft. open environment (1,229 sq. ft. floor space) with ceilings that are about 50% at 9 ft. height, and the other 50% rising from 9 to14 ft. The K2s reside near the exterior wall where the ceiling begins its rise to 14 ft. before dropping back sharply to 9 ft. near the middle of the space (about 16 ft in) where the great room, kitchen, and dining room all intersect. The vertical, suspended 5 ft. drop wall at this point has HF absorbers to reduce echo. The rest of the space is largely open except for typical house stuff that Floyd Toole would find normal and fine.
    Out.
