12" Tapped Horns?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I seem to remember a thread by Deadbeat about 12" tapped horns, based I think using the Ciare 12.00sw.  Any links or any suggestions?

I've been playing around with a dual 6th order bandpass box using the Ciare, potentially to get the size down so i could get a pair of them and my X15's in the car.  At the moment its one double 18, but not both.

Curious how a single 12" tapped horn would compare with a double 12" BP6 of roughly same cab size?  Range would be around 40hz to 110hz.  Obvious benefits of less drivers and less weight if they could get to similar levels, and I could prob go for another pair for the bigger gigs then.  I guess 4 12" TH's would be quite good if done right?

	Before hardly anyone knew what a tapped horn was, I designed one for the Ciare 12.00SW. I called it the 'stepped horn' take a look at www.speakerstore.nl and you will understand why. This one works very well with the Ciare 12.00SW it is aimed at 30-80Hz so real sub duty. Best regards, Walt

	That'll be the one! Thanks. I'm going to have to look into this abit closer i can see, I need a quite specific footprint for this box so it fits into the carrying space available. Folding will be the key i think.

	You should do something like the TH Minis. I think it is close to this internaly

	Walt's stepped horn is the only sub I've built (much respect Contour) and you really can't argue with a design that goes that low and that you can build in a day. The whole thing with a Ciare 12.00 SW cost me under 150 quid to build. The only thing I'd say is that, to my ear at least, it lacks some punch in the kick drum. This isn't a problem for me; I don't play techno/dance and it sounds sweet and warm crossed over at 60-80 Hz. I've been thinking of ways to fold it but then I saw this: http://www.speakerplans.com/forum/forum_posts.asp?TID=21659 If I ever find the time, I'll build a single 12" version of the EAW BH but with steps after Walt. I've sketched it up but need to work out the chamber size for a Ciare 12.00 SW. I'd be interested in what Contour and Marjan think about this ... S

	The steps thing is much better at the LF your TH works at. The BH will suffer...it's not the right design imo to 'step' - the current folding is efficient re wood - stepping the straight panels isn't such a good idea... If you want a compact beast, chop and fold the stepped horn into a box Or design your own for a larger bandwidth.

	BH 760 dont do 25 Hz. It is all a marketing mabmo jumbo. It has too small mouth and not long enough horn to be able to do that. Lab Sub cant do 25Hz and it is much bigger box..

	BH882 is the one you're talking about (absolutely massive W-bin, as seen in MOS). Oh, all these model numbers...
