4in TB fullrangers (tiny) project (1 Viewer)

[KyleGS]

I'm interested in a pair of TINY TB fullrangers for my bedroom. I've noticed that the 4in models have more cone AND a good bit more excursion. It seems to me they would be far superior to the 3in models on the bottom end.
My question is this:

How do I determine which of the three 4in TB drivers will extend the smoothest on the top end?

I'm not overly savvy in reading and interpreting driver data.

Can anyone give me some tips or hints on this -- or better yet-- does anyone have any experience with the 4in drivers running full range?

Thanks a bunch guys


Here's a few quick links to the drivers:

Kyle,

I've got a pair of the first and third TB drivers you posted links to but haven't had a chance to play with either yet. They both have response graphs up on the PE site. From those graphs, the 654S appears to have flatter response and more extended top end. The one downside is that it requires a slightly larger box than the 656S. But the 654 models better if you want a sealed enclosure. Unfortunately there's not a response graph for the 616S, but it seems to model very well in a ported enclosure; basically the same as the 656 but with a paper cone I'd expect it to sound better than the 656.

So I guess what I'm saying is, if you'd like a relatively small, sealed enclosure go with the 654S. If you want a relatively small ported enclosure then I'd say go with the 616.

I've used the 616S as a full-range driver. It really doesn't sound that bad, though you'll miss some air on the top end.

Bite the bullet and get a pair of Creative Sounds' WR125S 4" units. Drop them in 7 liter boxes tuned with a 1.5" diameter by 4" long port, and enjoy.

IMHO, there isn't a better wide-range 4" driver on the market, and I'm not saying that just because I designed it. You'll be VERY hard pressed to find anything with much more top-end extension, and nothing out there comes close in the bass range. There's only just a few 5.25" woofers that can equal the bottom end of these units, let alone zero 4" drivers.

I've been looking at the WR125S for some time for a desktop nearfield system. Are there any kits or published plans for the driver? I know it shouldn't be that hard to design something but I'd rather not if I don't have to.

Anybody?

Build a 7 liter box, and use a 1.5" diameter x 4" long port. The boxes we built up for demo measured externally 6" wide, 9" deep, and 12" tall. Built with 1/2" thick MDF (plenty stiff for this cabinet). Centered the driver on the front (vertically and horizontally). Port mounted at the top of the back, input cup at the bottom of the back.
