We cross our TH 118/SM 80 at 130Hz. It outperforms any KF 650z rig I have ever used.

Kemper Watson would probably say the same-he went from a 650 rig to an SM80 rig as well.

Best regards,

...went from a 650 rig to an SM80 rig as well.

So did I.

Many BE's that run the system are concerned with the tunings I use. They fear there will be lack of and or sloppy low mid punch. Once they start to drive all worries are lost.  Some end up cutting in the 100-120Hz range.

Here are the actual HP/LP settings I use. This is used with original Crown ITech DSP.

SM80:

HP Butterworth 12db 125Hz

TH118:

LP Bessel 24db 130Hz

Delay 1.25ms

Interesting. I may try re-tuning ours...I am crossing a little lower than that, around 100 Hz, and using a steeper roll off on the SM 80.  Sounds fine like it is, but could maybe squeeze a little extra low-mid juice out of it.

Are you also reversing the polarity of the subs?  Danley has suggested that it sometimes helps.  Also, isn't it the tops that you are delaying 1.25ms, rather than the subs - to compensate for the delay caused by the horn path of the TH118?  According to Danley, the delayed response of the sub should be somewhere in the range of 3-20 ms.  1,25ms seems short - I think our tops have a delay set around 5ms.

The polarity is flipped on the TH 118 and yes that delay setting is for the TH 118. We spent a better part of a day tuning the system with SMAART 7 in an open air environment. I also have several EQ filters engaged on both the SM80 and TH 118. Again these tunings were developed using Crown ITech DSP.
