Title: Re: Extended horn Post by 40s_and_deaf on 11/24/07 at 23:59:14 Anyone? Again my line of reasoning with extending the horn in length is to make it resonant nearer to a quarter of a wave of the desired frequency which would probably be about 25 Hz and should plumb the depths on some types of music......yes/no? |
Title: Re: Extended horn Post by Bart_West-VL. on 11/25/07 at 10:31:04 Just a guess here: The circumference of the mouth should be twice as large. This would mean: doubling the height and width of the WO. Possibly the depth too. But it's not a horn, so everything is a guess. Even if it was a horn, I still couldn't tell you how to do it, just guessing. Bart |
Title: Re: Extended horn Post by 40s_and_deaf on 11/25/07 at 10:50:53 Cheers for the reply Bart, I was thinking of maintaining the flare in the horizontal plane only as per the original design....as it stands one plane is parallel and the other flaring at a given rate. I guess apart from wasting some mdf on an upper deck to the WO I'll have to build and report back....I was hoping somebody might wade in and say whether the design relies on the horn acting the way I want it to or whether this will be another of my lost weekends in the shed turning an 8 by 4 sheet of 18 mm mdf into off cuts and dust. :-/ Another thought and as the walls of the port are parallel in one direction (top and bottom) this will possibly support standing waves at some harmonic are there any users lining the horn with say rubber carpet underlay or something like that to break up this surface? So many questions but not having any experience of the WO while knowing what I want to hear from an enclosure it would be good to know that the WO will plumb the depths that say a similar scoop type design won't. |
