Best *tiny* full range driver overall?

[peteleoni]

Hi guys. I have a new project in mind. One that would fit a tiny "line array" in tight spaces. On this one efficiency would not be as important as my last build which is a pa. This will be used in small spaces like cars etc. Accuracy will be the key, cost may be a factor, 2" or less is paramount. What do you guys think?

Tough to beat a tiny TC7FD, little brother to the famous TC9FD.

Small tight place and line arrays usually don't mix.

You'll be facing combing at its worst.

 

[peteleoni]

Re comb filter, yep. But it will probably will still be a net improvement over separated multi driverss

 

[chrisb]

both of the above posts are probably correct, and you don't know for sure about your own last point

 

[peteleoni]

Well....I am within 4 feet of my small line array stage rig, walk away and still hear about the same (excellent) fr balance, without notable hf variation, I would assume that a small full range "array" in a car or rv crossed over to hidden sub will also work well. Worth investigating imo.

I find the Tymphany TC6FC00-4 to be exceptional in detail and the Neodymium magnet makes transients really shine. I cross them over sharply (24dB/octave) with an electronic crossover at 300Hz, so not strictly full-range, but wide-range. Good luck!

I thought comb filtering would not be an issue if drivers were within 1/4 wavelengths of highest frequency. On a 2" driver we are getting pretty close to coupling everything from 10k up are we not?

pete - certainly can't hurt anything to try - just keep in mind that for many denizens of this sandbox, "mini" and "line array" are contradictory terms.

 

[Pano]

The little TC7FD 2" is supposed to play down to about 150Hz. How low can it play when combined into an array?

 

[chrisb]

well, I guess that depends on exactly how many, and how much total system sensitivity you're willing to throw away in order to get there

Your honesty is duly noted sir

With a pair of 2” C-C pushes ¼ wl up well over 20k, but in an array — assuming ear is at the middle driver — C-C is 2” x n/2 so combing will happen at lower frequencies will it not?

As we age combing becomes irrelevant.

I was thinking no comb filtering from 10k down I meant to say. Probably thinking 9 drivers per stick. Depends on the driver I go with. Pretty amazed at what my little 9 unit 3fe25 stick is doing combined with a 12" car sub in a 1 cubic foot sealed box is doing.Incredible spl actually.
Way more than my Mackie units were doing and clean clean clean, deep deep too.☺

my last audiogram is the best of my who!e life, and i'm not really young

why not use waveguides instead of conb filtering, it is easy to do with small drivers.

Tang Band W4 1337 kicks *** and do some monter 42 Hz bass in a MLTL.
W4 1320 is also nice, with a big scene.

This is one heck of a forum. If this forum produced collaborative products they would actually be worth buying. ☺

These have always been of interest to me. I'll build a set one day with a BFM Tuba18. Maybe you will find them interesting.
