If i were you, i would use 24db/oct BW. Not 12. It will require reversing polarity on the hf too.

I'm also still looking for nice professional grill's, but they are indeed hard to get.
Does anyone have a nice adress? I'm looking for honey cone cutouts (or round if not possible). The plan is to have te same grill for the TH-18 and the mid/high.

@all bass
Thanks for the link! I also had some time to do a outside measurement, but couldn't do al the things I wanted to do.. They sound much better already, next step will be measuring them with the TH18's. After that (will take some time) a SMAART course by probably Timo Beckman.

I also started with designing a dual 15 cab for on top of the TH18 or only with the mid-highs.
It has tot have a small frontal area (as wide as the TH18) so 571x571 is the target. I simulated it as a reflex cab, but I can imagine that there can be a bandpass effect? Cab is tuned at 43 Hz, and I am planning to go with a push pull configuration. Topview: (line's are a little bit crooked because of the conversion by dropbox) This is still a quick sketch and with this arrangement, it will be a little hard with fitting the drivers.

There will be a small peak corresponding to the depth of the cavity, probably around 160hz~180hz.

I think that depending on the requncy range you are planning for the mid range cab the slot loading will add a peak just where you dont want it.
I cant help thinking that a more gentle angle might work better like a manifold speaker loading (an inverted piramid baffle with the 2 15inch drivers on opposing sides of the piramid) |

"I think that depending on the requncy range you are planning for the mid
range cab the slot loading will add a peak just where you dont want it."
So all Cubo subs are junk? Do you not own an EQ? The peak is less than what you will see on a small folded horn (or a Cubo). Edited by _djk_ - 03 October 2017 at 10:25pm |

The range will be 40/45 ish to 140/150 ish.
Maybe get rid of the two front parts that are 10 cm wide, then the slot will be a little bit shorter.

Dont Cubos play everything "on the same note"?
If front is square you could place ports horizontaly and speakers vertically if they dont fit. Or use tube ports. |
