Default Full range flat arrays (big or small) ?

I've had luck with 2 drivers (5" frame) in a stacked vert arry.

There was the 7th veil stack of four 2" bandors.

there is the audience lsa line using 4 of the a3 xbl drivers (82mm frame) with 6mm true xmax (not p-p xmax).

or even bcherry on audioasylum running 4 of the 2" jordans
jordan JXr 6HD

"The 4 driver array is singing happily for the past few months. The combing effect is not noticeable..............Yes these are smooth like ribbons, except they play almost full range; the moving mass is only a bit more than a gram. Very SET-like sound..............The net volume of the box is 16L, sealed and starts to roll off ~150hz.........I'm using 12ohms/2u2 (tuned by ear) and it's 80% there." (to boost highs)"

Floric has run an 8 unit array using the fr35 peerless driver (84mm frame) with a little boost.
"since some weeks I have 8 Peerless fr35 per side in closed 18l. Actively crossed so a sub (per side) at 150Hz, this is really great stuff. I use a little passive boost for the hights 15u // 1,2R....... Dynamics, soundstage, tonality is great. But the little beasts quite difficult if you have to find the right position."

The ids25 by roger russel (none has made a cheaper clone)

Or the kuze array of 32 two inch tang bands

Anyone else run a flat array with full range drivers?
How long was the array ?
Adding eq worked better than expected ?

is an array of 8pc tangband W2-800 (with SDX7 sub). you might need translation, as it is in dutch

4th page................
" I have to agree at all what I want instead of tapping ever to edit ... I am listening a little reminiscent of the Final 80 electrotechnique states that I have had and that is a GOOD thing. Volgens mij zijn dit waarlijk snelle drivertjes! I think this really fast driver gently! "

but he uses a bunch of eq..................

otherwise baffle step below 1khz, and sloping down till driver dips I think.

There's the Twentyfive array, using 25 (surprise!) Visaton FRS-8M units in a straight array. With a ruddy great filter slapped on it (draw your own conclusions). I'm not convinced by this particular design, but am willing to be proved wrong. http://www.lautsprechershop.de/hifi/...ntyfive_en.htm

Ah, He finally added another post !!!!!!!!!!!!!!!!!

"I'll have some "ear test results" this week although they sounded fantastic in my shop with a very cheap receiver. I won't be able to get some graphs done until my friend with his REW gets his microphone and new board. What an awesome driver!"

82mm frame x 4 A3 drivers = 12.91" tall flat array.

That long xmax on the a3 justifies the cost (compared to other small xmax drivers) assuming the driver sounds nice. The distortion curve looks nice until it goes past 3mm Xmax.


I was thinking of 6 of the 2"x3" tang band for $150 (the a3 and tb have area = 32cm2) but 1 of the a3 drivers can more similar air (Sd x Xmax) and probably sound better (distortion wise).

Then again, that a3 has way more output that similar priced jordan or bandor units.

I don't want to hear a 4 A3 driver array because I'm sure I'd love the way it sounds then be unhappy untill I make some !!!!!!!!!!!!!

I assume using cheaper drivers and crossing them 24db @ 200hz would get me similar results. I require multiple 15's moving the air in a room, sounds more real to me.

I think a mini line array (4) using the dayton 8 ohm rs-100s or now even the mark audio chr70s or even the alpair 6 square frames. Would there be any issues in trying a mini line array in an Open Baffle, besides maybe the crossover point tot he sub due to the baffle roll off?

I've looked close at the rs-100, it did best in a car audio test beating out the tg9, tc9, l3 and peerless 830986.
http://www.diymobileaudio.com/forum/...86-review.html

"Scores: Max points 100

Overall SQ (max 25 points)
Tonal Balance (max 20 points)
Low-Frequency Extension (max 15 points)
Clarity @ low volume (max 10 points)
Clarity @ low volume (max 10 points)
Listening fatigue (max 10 points)
Easy of Use (max 10 points)

All scores are base on this group!!!


DAYTON RS100

The Dayton RS100 has the great low-end (down to 125 at moderate volumes, but 160 at 24DB is best) and great detail, This thing plays loud and say clean doing it and handles power very well. But because of the low-end it can make the midrange sound a little fat and make thing run together a little, but it was easy to fix (EQ out or back in the separation). I loved strings instruments on this driver. I would keep it around 5-6khz on the top-end, above that you well need some very good EQing skills, but it is just a great all around driver and the most dynamic in the group.

Overall SQ: 23
Tonal Balance: 19
Low-Frequency Extension: 15
Clarity @ low volume: 7
Clarity @ high volume: 9
Listening fatigue: 8
Easy of Use: 6

Total: 87"

response is a little lumpy past 1khz and 100mm frame versus 84mm of peerless tc9 (or audience a3) but comment usually are "clear sounding" similar to comments of the 4" bamboos I'm running right now.

What's up with the 5db dip past 3khz centered at 6khz (on the rs100) ?


its waterfall Rs100-4 looks better than the tc9.................
I wanted the tg9 till I read this..............
"The problem I had with this one is, it was too in your face. I just couldn’t get it to smooth out like the other drivers in the group. I thought it was going to the RS100 that I would have this problem with, but it was this one. This one seem to have the best attack and decay in the great."

maybe it is the spikyness 2-4khz on its graph of the tg9
http://www.tymphany.com/tg9fd-10-04


The alpair 6 (124mm frame) is an option, but for a 4 driver array, I'd prefer no more than 84mm frames.......................

Ob's can be tricky.
But if the feq is near the crossover point, it should work.
But these little drivers can easily bottom out run wide open on an open baffle. So box them for excursion protection, or run a crossover.

4 of the tc9's (flat array) or even 9 in a convex array should be fun and won't break the bank either........................
