Hello DIYaudio,
Im giving designing my first subwoofer a go, for a La Voce SAN215.30. Its based on the cyclops design and then a design of a friend who came up with the plan originally, the idea is to not worry so much about size and get as much output in the 20 - 60/80 bandwidth, whilst still sounding nice. Any ideas welcome, TH, TL etc etc
I understand I need half SD for one of the horns/paths but cant seem to find any reading material on what other parameters need halving or leaving alone. I have looked! perhaps even scrolled past it. New to hornresp but am slowly working it out, I knew this day would come and am happy I have such a plethora of drivers lying around to design boxes for.
Thanks in advance.

Perhaps half, Vas, Sd, Mmd.
Iv tried this but still run out of Xmax (and even Xmech) way below AES power.

If I were you, I would Google an online Hornresp guide. Then find the HR input parameters for the original Cyclops and work your way from there. Other designs to consider are the Othorn or the Gjallerhorn.
I wouldn't half Vas, Sd, Mmd or any of the other driver T/S-parameters, just focus on the horn parameters (S1 - S5 and L12 - L45).

Greets!
By 'half', I assume you mean a 2:1 compression ratio (CR), which is what I simmed to get a 20-80 Hz BW @ >120 dBm/2pi/700W/Xmax TH
If you mean by making it a stepped pipe rather than typical tapered, then use mine as a guide to best practical number/size of pipes.

Check the BOXPLAN-CYCLOPS workbook from the following link: http://www.diysubwoofers.org/sheets/
You can resize in the workbook to suit your requirements. It will provide the corresponding Hornresp sim.
Cyclops layouts don't go particularly low. There is a price to pay by splitting the path and trying to fold it up in a rectangular shape 🙂 .
For home or casual use, I'd just go with an offset TL - it will be the smallest option to achieve a particular F3.

With or without that dotted line as a brace or a folded segment. seems to work well
