I've been thinking about an inset and then using a perimeter gasket to mount a plexi or aluminum insert onto so that it's isolated from any MDF baffle vibes. Cost is not prohibitive with aluminum from our suppliers. Aluminum would be very nice to try to use but I don't have the capability to machine it at home and I wonder if that surface might not resonate or ring possibly. I will probably try setting up the 3's and 8's in the 1/4" oak as a dry run, but I found a local supply house that will cut the plexiglass to a nominal 65 X 10 for $30 each. The only choices I see are 1/4" oak from big orange, 1/4" masonite, 1/4" aluminum, and 1/4" plexiglass. All this is without a polished, finished crossover so take it with a grain of salt.Ĭhuck, you're progressing! Will your 65 x 9 insert be plexiglas? Do you plan to surface mount it, or route an inset deep enough for the plexi and mounted Neo's to drop into the inset so that the Neo's faces will be flush with the surrounding MDF? 5 was not enough, 6 was OK, 8 really sounded great. So far I have tried the array I have setup with 5 Neo8's, 6 Neo8's, and 8 Neo8's. Thomas or Jon can probably make a better guess than me. I just don't know enough yet to tell you. I am pretty sure 6 Neo8's and 12 Neo3's would still work, but I think it would be stretching it a little thin with 6 RS225's. Just what the tipping point is for the line array phenomenon to go away or to appear, I am not sure.

As soon as you start decreasing the amount of drivers involved, the efficiency goes down and the drivers are now being run at higher levels.

Part of it is the fact that each driver can receive a 10th of a watt and produce a very large sound but the single driver is running basically at idle. yet! But from what I have learned, a lot of the line array theory is based on so called 'floor to ceiling' line of drivers in order to produce the wavefront and to take advantage of the mirror imaging of the floor and ceiling to give the wavefront the 'line array' properties that go into making the sound a line array is associated with. I am by no means an expert on line arrays. Sweet- then you can "rent them out" to anyone going down the same path- sounds like you won't be needing any comparisons done with RD50's, eh? I've got a pair here that can be measured, but I've been might busy- as we sometimes say back in HQ, slow work takes time. PS - I will probably build a Neo3 jig as well to go with this one. Just PM me as time goes on and we will work it out.
Once I am done using the jig on my project I am willing to lend it out to anyone seriously building these. I am able to route out a hole for an 8 in seconds now. That being said, I am tired of not having a jig to make the mounting holes and indents for these things so I built a jig. OK, the Neo8's are sounding so good that I am taking them to the next step and getting ready to build another baffle that will hold them and the Neo3's properly.
