Ive been researching DIY ESLs and DIY Ribbons for quite some time and have been putting them off because of the difficulty of the construction and their main benefits were negligeble to me...
Im on an extremely low budget, by most people on this forums means and would love to complete a line source. I have the resources to build a DIY ribbon (access to machine shop and neodymium magnets), but have heard that they usually end up sounding poorly and being extremely inefficient. I also have the resources to build a DIY ESL.
Im looking for something that will match the performance of the bohlender graebener RD75, without sacrificing the top octave if possible.
The only issue is...I want to have extremely high sensitivity (match sensitivity of the woofer array) and a crossover point of 300hz so I can cross directly to a stack of RS390HFs (4 of them to be exact). Id love to run it dipole and take advantage of the 6dB+ boost from the combination of the front and rear waves to drive down distortion on the bottom octave (which occurs at 1 octave below the fundamental frequency of the baffle). If I can get the midwoofers out of the equation...Ill save a lot of money ($350 for amplification + $500-600 in drivers).
I realize its very difficult to get high efficiency from a single panel, but what if I made several small panels with extremely small CTC spacing? I could make 10-12 8" ribbons/8" ESLs per side.
