• Disclaimer: I love listening to experienced people. However I do not do everything they say. I would like to hear them as it can direct me and save me some resources like time and money and make me think of things I have missed and need to experiment on. I am all for experimenting.
• I am in the process of building a new system. I already have a horn loaded system and I have been trying to correct what I have been hearing and identifying as wrong. It came to a point that now I am completely changing them. The system I started was a klipschorn. I changed the woofers, the drivers, the crossovers, the midrange horn. I tried aligning the midrange and the tweeters. I changed the midrange again. I started building midrange horns etc. I do not want to go into detail and waste your time. Here is what I am trying to build now. 
• There will be most probably 5 channels but may extend to 6. I ordered the tractrix and the JMLC from Autotech, Poland.
• 
  
• Treble channel - 9600hz - 45000hz - Fostex t500amkII (I have it and I am happy with it, I will keep using it in this system as well) 
• Upper Midbass - 2400hz - 9600hz - cf 1000hz JMLC profile round horn with 1" mouth - Radian 475 be-pb compression driver
• Lower Midbass - 600hz - 2400hz - cf 200hz Tractrix profile round horn with 2" mouth - Radian 850 pb compression driver
• Upper Bass - 160hz - 600hz - cf 110hz Tractrix profile round horn with 6.85" mouth - Supravox 285-2000 paper cone alnico driver. There I did 2:1 throat compression (see details in the sketch in the next message)
• Bass channe l - Still looking for different solutions.
• 
  
• *Sixth and optional channel: 
• Sub bass channel - 20hz - 60hz - Tapped horn - I built this tapped horn out of 22mm mdf. It is 2.44metres tall with a single fold. I put Eminence 3015lf in it. I am not sure if I will use this channel. I may use it up to 60hz if my solutions for bass channel does not satisfy me down to around at least f3 35hz.
• 
  
• I just did a similar structure to cessaro as with this it would be very easy for me to build and adjust channels forwards and backwards. Just the upperbass is fixed. (see sketch drawing below this post)
• 
  
• I have not yet figured out the crossover. I am hoping to make a good, passive network for >160hz and drive the bass (and sub bass if here is one) with hypex class d. I am not looking for an analog or digital active or dsp solution. I do not want to go for multi amps setup with an active crossover, if I did, I would go for the multi dSet solution here on this website.

• I really find my amplifier good and will try and drive all my channels from 160hz and up from that. It is a 845 based amplifier. The 845 is driven by 300b's and WE 310a's. It is not a common amp and as it is made in China, most people dismiss it. It is a Line Magentic 219ia. I like listening and deciding on equipment as much as possible (although it takes years and years to learn what to listen to). This was the amp for me upon listening. It does not exaggerate, it does not sugar coat, it plays naturally but does not sound cold or flat (hate using these words for sound, but these have become somewhat common for talking about the treats of sound). I think it will have even more headroom and play better when the load below 160hz is off of it.  For <160hz I plan on using hypex class d amplifiers. I have 175watt ones. I can get 400watts per bass channel (depending on my solution, I can look for other amplifiers too) I have read about the dSet solution on this website and found it logical and fitting. It may be a future project for me.

• ps. I love cats and why I love the name of the site. I have two in the house and 22 more silly ones that I named, love, feed, take to the vet regularly (actually the vet comes to us). The 22 have their own room with places to sleep and play at the entrance of my house. Have 5 dogs we got from street and off from some mean people's hands too. I have no wife, and a good job as well.
