Tapped Horn little project

Hello,

I am starting a new project with a little tapped horn based on this one: http://www.hififorum.at/forum/showthread.php?t=3433

The driver is now unavailable, so I planed to use this one: http://monacor.co.uk/products/speakerbuilding-pa10-12/vnr/105270/

I played a little with hornresp and i get this:










Any advice or suggestion are welcome !

Thanks,

I have a question about excursion and power:

The limit seems to be 16W for 112 db SPL.





So is it a problem for a TH for HT in a 25m2 = 280sqft room (listening distance at 2.8m = 9.5 ft ? Do I need much ? Or what should I do to improve that ?

Is a class T amp of 20W will be a good solution to drive it thru a miniDSP for pass band filter ? Or better using a Gainclone LM3886 based one ?

Hi all,

I have an other question about the horn building: I want to have a side opened mouth like DTS-10, but I don't understand in this case how to measure L34 and S4:



- Is S4 always the end of the section (S4-2) or is it the area of the aperture (S4-1) ?

- How to measure L34:

* Begining of the aperture L34-1 ?
* Axis of the aperture L34-2 ?
* End of the aperture L34-3 ?
* Always the end of the section L34-4 ?

Thanks !
