tweeter integration with Dayton AMTPRO-4

Yeah all passive, the mini is just a 1.5uF cap and level matching resistor.

You have some cool stuff there 6th Planet. I used to just do audio for my car but after finding this forum, I'm inspired to do home audio too! I'll see how it sounds with just the Pro4 and then maybe experiment with adding a Mini 8.

Thanks, car audio is where I got started, too. I was into wood working and one thing lead to another... if you'd like more ideas/info hit up the Tech Talk over at PartsExpress, lots of nice builds and speaker geeks that can help ya on your way.

The datasheet for the mini shows a drooping frequency response that seems a few dB lower than the AMTPRO-4. Since you used a level matching resistor, were you padding both of these down to match the larger drivers in the system after baffle step?

My phone won't show photobucket , but if you click the link I posted there's a xover schematic on the third page. That build was back in 2014?? So hard to remember what I did off hand.

Thanks for the tip, I imported the Dayton drivers from PE & spotted a build on their site using a pair of AMT minis with the PRO 4. I'm hoping, the AMT PRO 4's will sound good on their own with some EQ once they are up and running.

I used the ND20FB at 12K with the AMT3-4. I definitely agree there's a benefit in filling in the top end.

Looking good! Was this a passive design & did you use EQ?

 

[jrh0516]

This was a passive design. Aesthetics won out on the horizontal placement.

OB I prefer a stacked symmetrical arrangement as the summation is difficult enough to equalize. Plus I dislike making left hand and right hand baffles 🙂

 

[6thplanet]

I just wanted to keep with the AMT theme so I used the mini.

Measurement of my AMT4pro in OB mode. I think it was appr. 30 cm away. They where EQed.

What did you use to EQ?

May I suggest a "low profile" tweeter, vertically in between a pair of AMT's?

Here's a suggestion, but I just am using it to show how small a mounting ring you can get:
