Hiya

Yep we added extensions and they work great, and are still going ! You can find out about them at our website... DiY HiFi

.p.

Bet this setup sounds awesome!

Hiya. I've had a dig and can't find our original cut sheet ! I'll go dig them out of the trailer and measure them up. If you want more info on our build I have a thread running over on Speakerplans for more info.... https://forum.speakerplans.com/th-unity-horn-solar-sound-system_topic63191_page1.html

Those barn doors flatten the response nicely!

I'd like to see what the impedance curves look like for the TH with and without the "doors".
If Fb is being lowered (which will show up in the impedance plot), the power handling of the driver above Fb is also going to be reduced.

So.....can somebody do it?

Hiya I pinged ya the dimensions...did you get them? Ta. P

As for measuring the impedence with /without doors..if anyone wants to come down to Melbourne for our next gig feel free to go for it ! Sadly I just don't have space / time to do it.... P

I did a few sims, using another TH model that I had. The Fb will shift, but not by much. In fact, depending on the new size of the "mouth" (caused by the barn doors), and how lossy that arrangement is, the shift might not be noticeable. There is some gain around Fb though.
