Hello,
I am starting a new project with a little tapped horn based on this one: Bass mit 10Zoll Tapped Horn - HiFi Forum
The driver is now unavailable, so I planed to use this one: SPA-10PA
I played a little with hornresp and i get this:
Any advice or suggestion are welcome !

Hi TundraLDT,
you pointed it out !
The limit seems to be 16W for 117 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 ?

As long as you use a hi pass filter I would at least double that power rating for the amplifer.
Dependent on the driver and how it behaves when pushed past Xmax you could probably use even more.
Hornresp does not take into account any thermal compression in the driver.
You dont want the amplifier to clip as you get towards Xmax.

A Monacor SPA10PA TH that can be stuffed
Hi,
IMO, (After doing a math check.. the first one done here?): You need at least a BW 4 HPF at ~32 Hz; or a LR4 just below 30Hz to preserve a use of maximum available cone excursion before x-max limits the possible BW.

Hello Bjorn, very nice Math ! Thank you very much.
I want to ask you which kind of response curve will perform better, n°1 or n° 4 ?
N°4 is flatty, little more SPL, but N°1 goes lower. Which will be the best for HT tapped horn ?
@Tinitus: "but try ask yourself why its got such weird high Qts ?" Lower Qts == higher prices

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 !
