Dayton DVC 15" horn?

mr. doom · 21st February 2011, 01:40 PM

What is the smallest/lightest design I can use this driver in.
I will power it with both a 80watt and 350watt@4ohm amplifier.

I know it is not the ideal speaker for small horns but I would love to get more out of it than a BR box can.

Looking for good output from 60-100 Hz more than any sub-bass.

Hi mr. doom,

You got the wrong driver for the output you seem to be shooting for. You could just stuff it into a 1 to 2 ft^3 close box and see if that is really what you want "...output from 60-100 Hz more than any sub-bass....). As a BR it looks good @ about 200L. As a tapped horn it would like to see over 500L (you could squeeze it to 270L). Both, the BR and the TH will go low. Maybe bjorno can chime in with his T-TQWP solution, it should be smaller.

Regards,

According to WinISD a BP6 should be possible at about 150L:

Rear chamber: 100L/45Hz - vent dia. 15cm -vent length 15cm
Front chamber: 40L/85Hz - vent dia. 15cm -vent length 6cm

Regards,

Thanks for the suggestions. It is in 125L tuned to 25hz now and has no "kick" at all, great for rattling the windows but probably useless for what I want it to do.

I went to the wayback machine and found a old Horn project for the Adire Tempest (virtually the same driver) http://www.esnips.com/doc/19fc9c09-0...tBassHornPlans
I think this speaker was $100 ten years ago and a good value then.

Hi mr. doom,

Yes, that's a nice design. I would assume that it is driver specific, almost by definition all horn designs are, but you could enter it into Hornresp as an offset horn with your driver, and see. It also give a whole new meaning to:"...the smallest/lightest design I can use this driver...". :-) I'd take another look at a BP6.

And just for the fun of it the Hornresp SPL for the above:

Bjorno modelled this one for me a while back, still haven't had time to build it
