anybody consider the silver flute woofers and tn28 hivi tweeters for a real cost consciencous line array.

i'm just a guy wiht an idea... my audio experiences are small, i've only built one line array,, and i loved it, time for another

lets see if we can get a conversation going on this topic.. it looks extremely appealing
 
A little bit of math to help you out;
Center-to-center distance of 8" woofers is = 1695 hz.
That'll be your crossover point. (13560/c-t-c)

8" woofers X 8 drivers = 64" high baffle. 72" would be better.
8 HI-VI TN28 X 1.875 = 15 inches high on the baffle.
C-T-C = 7230 hz.

Fs of tweeter is 1600 hz. It'll require a steep crossover.

check out dr.griffins white paper at

as far as i know,8" woofers would have to be crossed very low.maybe too low for those tweeters.
i hope more people will respond as i'm really curious about a line array with silver flute woofers

ps are you getting your supplies from solen??


Not too low for a big planar. The one i am thinking of is able to run down to 500 600 hz . Its a Mid/tweeter planar. I had the link and lost it from a post somewhere in here. 35 inchs 45 and inches and i think they had 52 as well.
 
The 8" SilverFlute's look like they can make it too 1700 hz.
The HI-VI TN28's will probably struggle at that crossover point and then theres that c-t-c spacing problem at 7200 hz.
According to Griffin's white paper combing will start to appear at 7200 hz and get worse at 14,000 hz.

Madmike2 was probaly thinking of the B&G midrange planars.

The first project I've ever built was my line arrays using 10 Dayton 5 1/4" Aluminum Woofers and 6 Dayton PT2 Planars. Crossed over at 2500 hz - 4th order Bessel. That was before the Dayton RS series came out.
Now I'm starting to build a line array with 10 RS 7 inchers along with 10 B&G Neo3 PDR's Planars and I'll probably cross them at 800 - 900 hz. Won't know the actual crossover until it's all put together. I'm not worried about the sensitivity mismatch of the two drivers as it will probably be a natural baffle step correction. If I do need more SPL from the planars I could always parallel more of them to get it to match the woofers.

Before the RS series came out, I was planning on using the 6 1/2" Silver Flute's with the the PT2/Yag20's (they're made by the same company).

They'res also DIY'ers out there who built line arrays with only one tweeter. They'res a point source/line array boundary problem but in a small room at seating distance it doesn't appear to affect the imaging that much.
I like to have the sound stay the same - sitting or standing and walking around the room. So go with the planars. It really depends on what you want in the end.
