I would love to hear a comparison of both horns concerning the sound.Originally Posted by 1audiohack
Of course the yuichi can be crossed over much lower than the 2397, but how do they compare above 1khz?

I am ... *gulp*. very curious too.I would love to hear a comparison of both horns concerning the sound.

did some nearfield measurement of the 2216ND-1 and the port.
near field seems to be close to simulated.
the other 2 are the combined at 2 feet and 3 feet.
time to work on the placement and the room.

I spent some time playing around with the amps and looking at the distortion.
I ended up swapping out the NC400 and swapped in a single ended tube amp to drive the 2441 and another to separately drive the Fostex, and the distortion was more under control. make no sense as tubes are supposed to have high distortion (and there is still a 2nd harmonic dominant) and the NC400 is supposed to measure really well with very low distortion. Poor matching with horns for the NC400?
it also sounds way smoother with better holographic imaging. At that point, I was just enjoying the music.
I also played around with the crossover point. I tried 5kHz and 10kHz and found myself preferring 10kHz. Seems to paint a better coherent picture and sound more natural. Not sure if that's because the 5kHz wasn't tuned perfectly, or I just prefer the sound of the 2441/2397
Thanks. that's great advise.
some measurement and simulation definitely prove what Ian says. top is the measurement, and the bottom is the room simulation from REW.
having the actual simulation plus the near field measurement at least means the speakers themselves are behaving correctly. I just need to find a proper placement for them to sound their best.
And finally, the replacement 2216ND1 arrived and it works! A month after I ordered. Installed it and turning it up it is capable of some well defined thundering bass that shakes the room. Now I need to spend some time to figure out the right tuning for it.
In the interim, I was trying out different configurations to match the 2441/2397 and the Fostex. trying out different amps, crossover points, active/passive, placements.
At the end I still like the sound of the Fostex sitting on top of the 2441. Physically time aligned. And then the fostex has a 2uF cap for a simple 1st order filter at around 10kHz. that's the original configuration. The sound is most coherent, the imaging is spot on, sound stage and wide and back into the wall.
maybe sometimes the most simple solution is the best?

If you like it leave it as is.

I think part of it is that they are now driven by the same amp and DAC. So there isn't a mismatch in sound between the drivers.
the upside is that one fewer DAC/Amp cost less money.
the downside is i prefer the Fostex to sit up front near the lip of the 2397. purely aesthetic, but hey...
I will do so and now that I have two woofers I will spend my time getting the 2397/2216ND-1 match better. I was having fun and really pumped up the bass and the 2216ND-1 handled it with ease.
with a cabinet this large, is it realistic for it to be completely inert when the driver is pumped way high in volume? from touch alone, mine is not, there is some vibration, but at the same time, it is not resonating like crazy either. quite dull, but still there.
Response at my listening position, with the speaker tuned to flat at the ear. There is a pretty big suck out below 50Hz and then recovers after 30Hz. I tried to simulate it in REW room sim and it confirms that suckout. I tried to do different things and none of which helps other than making all walls broadband perfect absorbers.
Having mentioned, this flat response is rather... flat. After that, I tuned it to be closer to Harman curve which is way way more exciting to listen to. The amount of air it is capable of moving is pretty incredible. I also don't sense much in term of blending issue between the 2216ND-1 and 2441/2397. I ended the evening sitting in my room and enjoy some good music in speakers that I personally built. Bliss!
