Yes but using the 21DS115 in the type-C the width of the cabinet would become 81 cm.
Using the 21SW152 the width of 61 cm can be used due to the lower Le. Until now I still don't know which driver to use. price difference is about 100 euros here.

Those components are some powerful players smitske96. Does anyone have any background info on paraflex enclosures? When searching, paraflex seem to be the name of whatever hybrid of series/parallel BP6, transmission-line, tapped horn, planar wave or reflex one can come up with.
About drivers, if a Paraflex is anything like series BP6, low Qes is critical to low-frequency performance. In simulations I gained approximately 10Hz of extension (40Hz-30Hz) going from 21SW115 (Qes of 0,39) to 21SD115 (Qes of 0,24), in a 300L series BP6. Try to sim it if you haven't. |

I've tested the cab 2 days ago, results where encouraging but it needed more bracing in the mouth. For me they go low enough, I used 24dB BW @30Hz, HPF and 24dB LR @80Hz NOTE: those filters where just figured on the go, so probably not optimal. For amplification I used one channel of a CTS-3000.
If possible I'm going to add some bracing in the next coming weeks and test again. Also using the 21SW152 for the cab is on my mind. |

How did it go with this one? (the paraflex) I'm might look to built these over the summer. I haven't heard them though, so I'd like to hear what you think of them.

Instead if another TH-18, I gave it a try to build a paraflex design.
Test cab (not finished): Probably a bit light on bracing, but I'll see how it performs. Also the diagonal pieces will be added in the mouth. Powersoft module: If they pass the test, I'll build two out of ply, and add wheels and some small handles. |

Update: I've now got two Powersoft 3004PFC4 amps available. They would be ideal with 1X TH-18 and 1X top per side, running the TH-18 on two bridged channels. Other option would be to still go for 4X BR cabs, but the amp module would only give 1500 Watt per sub, which gives me no headroom

I saw that one, but those fotos are from another ebay lot (which alrrady ended for a more normal price). So I don't trust it

If you are looking at X4 that is on markplaats now - it seems as a pretty nice deal! |

Nikon and Canon people should not be married to each other. Why did you let this happen?

The Br cab design is almost finished but, I'm also going to build two TH-18's.
They will look like the original TH-118 with only two handles and the two wheels, that way it's easy enough to roll them around for one person. So two BR cabs loaded with 18SW100-4, two TH-18 with 18SW115-4. Reason for going for 4 ohm drivers would be that I've got some more amplifier choice, atm I'm looking at two K3 or one X4. Also grills: They have two sparing for cardioid arrangment, not going to use them, but install the speakons just for the looks.
