    The K-402 and K-69-A combination is really good. I know there at better CD's out there but I don't feel the need to explore them right now. I use the KPT-904 for the 120-500hz region. I like it, but maybe I explore other options. The thought of horn loaded lower midrange is intriguing. The bottom is handled by two horn loaded 24" Precision Devices, one in each front corner of the room.

    I am using broad band absorption from RPG, models Plate 1 and Modex Edge. For diffusion I use Modffractal from RPG. In addition I have some diy absorption and planning on diy VPR.

    A couple of rounds with Chris A and it sounds better than ever. This have been really fun The latest experiments shows a favorable lighter yet punchie sound when the level does not start to rise before 150hz and downwards.

    Thank's. Has not built DIY amp, hesitant about it.

    There is a problem with constant hssss sound from the K402 horns. I am driving them with ATI AT3000. The sound is not coming from the receiver. Can anyone point me in the direction of a amp with low gain and low noise? Not expensive…

    I have not done anything with the K402 settings from Chris A, only Applied EQ on the subs while measuring them alone. Now it is time for listening.

    Time for a update. FIrst of all, thanks again to Chris A for the extensive support! After Three rounds where I emailed him measurement files, the sound I have now is the best I have ever had. Feels like its the first time I really hear the potential from the K402 horns after they are dialed in. The Attached REW measurement is with 1/3 octave smoothing. I have not done anything with the peaks in the sub region yet and maybe I look into that tonight.

    I had a successful night. The latest settings from Chris A. are the correct ones. Only lowered one of the PEQs from plus 4.5db to 1.5db and the K402 measured very good in the sweetspot. The frequency range up to 300hz has more peaks and dips and I'll attack that tomorrow with the EQ function in REW. I only use attenuation, no boosting. Also sent Chris A the file from REW.

    Thank you for the replys guys! Really appreciate it Chris A: I'll try your latest settings. I use REW with a calibrated mic and will send you the file after tonight's measurements.

    Yes, the REW measurement looks like the graph in Xilica. I did not save the REW measurements, that's why I only show the Xilica graph. If the measurements with REW looked good I would not be bothered with how it look in Xilica.

    Hi I have tried to use the settings I got above in this thread, but the resulting graph looks cracy both in the Xilica software (Attached image), and the measured frequency graph in REW. Any ideas what I have done wrong?

    Thank you for your reply Chris A. Glad to hear that the Xilica XP4080 is a good choice.

    Just wanted to give you an exciting update. I have gone all in for active crossover. The passive crossover is sold and I bought a Silica XP4080 wich will arrive Tuesday. This is first time going active. I have only read about it. I do have experience with REW and planning to use the EQ function in REW. The above mentioned settings, am I supposed to change them according to my room, or let them be and adjust additionally according to how the speakers measure in my room?
