When you crossover a nearfield line array to a point source tweeter, do you use a traditional crossover or are other things involved? Same question when crossing to a line of ribbons. Norton

If it hasn't yet been pointed out a line array midbass with a point source tweeter isn't that good of an idea, as you have different radiating characteristics from the two sources Hi Bill. After wading through many DIY projects on diyaudio and the like( http://www.lalena.com/audio/calculator/xover/

http://yu-ra.tripod.com/array.htm
http://home.new.rr.com/zaph/audio/audio-speaker11.html
http://www.tolvan.com/edge/ ) ,a simple FAQ for people would be a pretty cool idea-as a sticky post on the forum perhaps??? Im sure some one could organise it here easily..this would save alot of posts -leaving time for the serious technical Qs to be answered. if i could get some of those 67c drivers shipped to NZ id give a line array a go :-) Cheers!

While I agree in principle, consider this: perhaps 75% of the technical questions that appear in various audio forums would not be asked in the first place were the posters not too cheap/lazy to buy/read a book on loudspeaker design in the first place. Of those questions perhaps 90% could also be answered in the various FAQ sections that already exist, but again the posters are too lazy to do a search. When you point this out to some they are offended that they can't glean in an hour on line what it takes the average audio engineer to learn from ten years of practical experience. For this reason when I do open a forum related to my site I probably won't bother with an FAQ section. Sadly, the majority of simple questions I answer regarding the construction of my designs are covered in the text that accompanies the photos and drawings, but for whatever reason that text seems more often than not to be read only as a last resort.

But life is short ;-) Have the copy and paste buttons at the ready i guess!
The business is worth it. btw the MCM 8" is an interesting choice indeed Qts=0.19 xmax = 16mm
;-) Cheers!

Actually my main reason for the MCM is the Bl product of 13, which is necessary for cone control with the high throat impedance of the Tuba design. Actual Qts is about .25.
