I think most of reader get my point of the car examples.  The main point is to follow the manufacture recommendation on how to use the driver.  Of course, if you want to do something different, that is your choice but don't come back and blame the driver.  Same as the car example.  If the car require 93 gas, don't put 87 in it and then ask why it won't run as expected.  Just like you won't fill diesel car with regular gas. 

Here is an example on how to use GOTO 505TT driver.  Use the GOTO S150 horn and crossover at 200Hz to 1kHz.  If you like to use other type of horn and crossover point, you are on your own.  Maybe good or maybe not but that is your choice.  Yes.  You are correct, every room will be different but the basic setup and crossover of the GOTO SG505TT + GOTO S150 horn will be the same. 

For GOTO SG370, use GOTO S600 horn and crossover from 1kHz to 5kHz.
For GOTO SG160, use built0in GOTO S3000 horn and crossover from 5kHz and up.

Use 1st order with active crossover.  Use 2nd order with passive crossover.


It is fun to try different setup but try the recommended one first and then tweak to fit your room, equipments.  As you pointed out, there is no simple answer but manufacture recommendation should be the 1st to try.
Hey guys, I bought the Goto 505TT with S150 horn brand new over 2 years ago. Guess what? I'd still be in sonic shit if I followed the 200-1000hz "recommendation". The 505TT does not perform well below 400hz and when I finally got a chance to measure the response, it showed a significant drop in output between 200-400hz. That explains why I've always had a problem integrating the upper 3 horns with my 53hz midbass. It wasn't so much because they were setup horizontally but the fact I've had a sonic black hole between 200-400hz. Ironically, I'm happily using the front portion of the S150 horn (150hz with about 4" throat) with a 6.5in driver John Hasquin had said good things about. Sonically, the 6.5in is slightly less sharp and less neutral sounding than Goto 505TT but the fact it goes down to 200hz is more than enough to make up for it. If I ever go 6 way I'd probably load a 6 or 8in into a 135hz tractrix for the punch between 150-400hz then load Goto into 200hz tractrix for 400-1200hz. Keith
