Default Another Line Array Speaker Thread

I’ve finally “finished” my line arrays using my DIY ribbons (see: Another DIY Ribbon thread). I say “finished” because the crossover is currently a junk box1k first order. I’ll probably build a more formal passive second order as a temporary measure until I complete an active crossover. The ribbon is a 47” seven segment ˝” true ribbon. The main cabinet is sealed and has 14 – 4.5” PE Vifa buyout mid/woof (P/N 299-432) in a 4-3-3-4 taper. The main tower is East Indian Rosewood with Satin water based Poly finish while the tweeter box and base are black lacquer. How does it sound? I just finished it last night and have limited time on it but like it a lot. The Vifa’s have surprisingly good bass and the tweeter sounds clean and extended. It has a crude crossover and I’ve made no measurements yet so you can assume my listening impressions are highly with colored DIY builder pride. It’s my first line array and first ribbon (in fact it’s my first full range DIY speaker).

Those look absolutely beautiful, but it looks like you ran out of stain on the bottom corner

Keep us updated how they sound with the new XO and some break-in time.

They look great Denis! The wood is spectacular, but that beautiful black lacquer probably took just as much work!

Cal - Thanks for pointing out the corner I missed. I'll get right on that

Paul - you are right abought the lacquer. It takes a long time - and just to site in a dark HT

Mark - my next project is to paint the house. I'm thinking of doing it in black lacquer

Seriously, after the tempoprary second order, I'm building an active fourth order plus three chip amps to drive each speaker (one for the ribbon and two for the mid/woofs). This probably won't get done before the winter.

Excellent! Workmanship.

Generally the line array speakers have an array of individual tweeters, they form a mounting gap in-between, and in your case it will almost have a full length. We will be keen when you are ready to post the test results.

Very nice speakers! Congratulations!

Could somebody tell me what are the advantages, (disadvantages) of the Line Array Speakers? Or, where can I read about it?
