Very nice. Can you tow the speakers in at all?

They are toed-in a tiny bit, but my apartment is so small that if I do more of it I will be sitting in the middle of the speakers wearing them as headphones. tongue.gif

Not sure about the crossover. There are 2 capacitors that seem to be undecided on what is right (parallel or series)
I am going to look for clarification because I'm having the same issue

I'm not sure where this confusion is, not in this thread at least? Here they are definitely wired in parallel. smile.gif

In the main thread for DIY sound group someone is saying they are in series. I think it was the designer.

I took it as in series and so did my friend who works with electronics.

Edit: I think I am wrong... Will update this or delete it once confirmed

I don't have the schematic so I don't know what it shows, but...

parallel capacitors

series capacitors

I saw your picture and you have your capacitors wired in series I believe, and I saw aspd's and they look to be wired in parallel.

The schematic says 26 uF, which only the 22 uF and 4 uF capacitor wired in parallel can give. smile.gif

Just take your soldering iron and put it up to the glue, it melts easily.

edit: oh it's glued to the speaker. :S might be hard to do this then :P

yeah, I could see someone getting confused that you have to have capacitors in parallel to get them to add their capacities together. opposite of resistors.

Alright, this is very much unscientific. But I've done a measurement (as seen, every channel on) with a calibrated UMIK-1 microphone and a DSPeaker Anti-Mode 8033Cinema connected between the Yamaha RX-A2020 and the t.amp TA1400 MK-X power amplifier for the subwoofers. This was done after the 8033Cinena finished its calibration.

The Yamaha DSP is set to "through", so nothing done there yet. But I'll try to start tweaking the DSP on the Yamaha and see if I can get that dip between 100-200Hz more flat, and update this thread with new measurements.

I'm surprised at the drop off between 20Hz and 10Hz there, that's qute a steep slope for a sealed setup, isn't it??

I expect that is a room null, and possibly the TA1400 MK-X rolling off, not the natural response of the sealed sub.

Was the mic at the LP when you did the measurements? If not, that null could shift around. It's probably floor or ceiling bounce, so probably won't shift much.

The dreaded T-nuts (had no issues).

 

 

I like the idea of using casters. (Great color choice BTW!)

What size are these?

The wheels are 80mm, bought from Thomann. Blue suits them. smile.gif

The microphone was located where you see it in the picture, about a meter away from right Fusion-10 speaker.

I wish I had more room, might give trying moving one of the subwoofers to another placement. But in this tiny apartment I don't have (m)any options.

The subsonic filter is in the Anti-Mode 8033Cinema, I can turn it off, but don't see why I should?

  • Red line, Anti-Mode bypassed.
  • Green line, with Anti-Mode on.

I've set 100 Hz as the crossover to the Fusion-10's. But disconnected them both for this measurement.

I'm surprised the anti mode can't do a little better.

If that's your mic position it's not representative of the LP, but its a good measurement to have. I wonder if the anti mode did better at the LP.

You got me curious as well. So now I placed the Anti-Mode microphone at my listening position and did a new calibration (hoping my neighbours don't freak out, those sweeps are mean!). Afterwards placed the UMIK-1 microphone at same place (LP) for some new measurements... OMG. biggrin.gif



red line is anti-mode default.
green line is anti-mode without subsonic filter on.
blue line is anti-mode bypass.
