Horn vs TL

[Gunawan W]

Hi all,
anybody can help me explaining the plus and minus of
Tapped Horn vs Folded TL for subwoofer?

I am going to build a sub, but still can't decide wether TH or TL,
the sub should have enough gain down to 25Hz, but don't need to shaking glass window, just comfortable to hear in room with size 15ftx25ft
(85dB at Fs, maybe?)

thank's

There are no pros or cons. Either is fine, as long as you get what you are after out of it.

Try my design.
Low cost
"Invisible"
No boomy bass

Hi Bjorn,
that is a smart way to hide the sub!

thank's

A true horn is BIG and gets the most SPL out of the driver, TL is smaller and less efficient. TH is somewhere inbetween. Apart from that, just get the system that suits your needs in terms of size, spl and response, as they have all the same soundquality, if done correct.

Thanks Mavo,
no wonder so many TH sub but hard to find TL sub thread in this forum.

So for TH sub what is a good program to use for it? HornResp?

Hornresp, yes. But designing those horns has a little learning curve. If you want reliable results, search for one of the million threads from people who allready build one and clone it. Volvotreter (he has his own homepage) comes to my mind here. Great stuff.

thanks Mavo, for the link,
what is the difficult thing or to look carefully when designing tapped horn sub?

 

[MaVo]

the difficult part is the decision if you spend !!! alot !!! of time learning from all the main th threads (use search) or trust in someones design.

I knew that, thank's
