Hi all!
So my daughter is requesting a project design for a wall hanging art piece that will serve as a music system as well. Size limit is 24” by 48” and 3” thick.
It will hang on the wall with a French cleat and be totally self contained. Music source will be an Amazon Echo and it will be covered in a custom printed acoustically transparent material which I have already sourced. Stereo of course with an Amp module of some sort inside.
Wide off axis dispersion is preferred of course and decent low frequency extension. I have sourced this woofer which seems ideal for this application

I’d like to keep this simple and my daughter is no audiophile.......loud, clear and good off axis response. So I’m hoping to be able to use the above woofer in a two way.......but can it mate with a dome tweeter or do I need a fullrange option instead?
My ‘thought’ was to pair them with the newer Peerless Corundum tweeter or DX25.....both of which have a low FS
Peerless DA25TX00-08 1" Corundum Dome Tweeter

Will this work or will I need to do an array of fullrange drivers to work with the chosen woofer?
Please remember the MAX thickness of this thing is 3”. I’ve decided on 1/2” ply stock for the front and backs leaving a 1.5” internal volume for bass response. I need .6 cu ft for a pair of the woofers so that’s been worked out to .9 cuft volume all in including ports and minimal bracing. That leaves roughly .2 cuft for the Alexa, Amp, and tweeter displacement.
Thanks in advance for the long read!

Something like an 'exciter' might be easier for a project like this, you attach one or more at suitable spots on a panel, which of course would have the art work on front:

The DA25TX is almost 3" high. Wide off-axis dispersion is best with a dome tweeter. Have a look at the SB29-series, the Wavecor TW30-series or even the old Audax TW034. Seems to me you have to cross that Dayton real low and fairly steep. And consider active when you're integrating the amp. This solution might fit, though there are lots of other solutions, like Dayton's DSPB.
I have a pair of Sb29rdnc.......will they go low enough (1.5khz steel filter) to work?
The off axis response of the DA25TX looks good to me.....what am I missing?
Thanks for the help

It wasn't the acoustical performance I was discussing 😉 And I forgot to mention the terminals of this mere tweeter are on the back of the magnet assembly.
i did see the terminals and instead of using thumb screws, i would get metric caps with ring terminals.....all in i still am within my 3" limit. Tweeter area can be open back
...but i'm liking the performance options of using multi full range...the Peerless TC7FD00-4 has near tweeter like off axis response and would be a much easier cross to the woofers......1st order should be fine
