21" 30hz Cyclops Horn Resp Input Data

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.
 
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
