Alright, plugged into some cut and bent up pieces of cardboard about 18" wide by 12" tall sitting on the table, they sound fantastic. Clear, sweet, and the open baffle sound stage is much larger, deeper and more precise than I've been getting with 8" drivers (in the near field, at least, since that's where I'm testing from). Even more astonishing, bass is pretty solid down to about 70Hz with some audible down closer to 60Hz, with no EQ.
Playing around with the EQ, I can get pretty much the same levels at the same frequencies as I've gotten with any of my 8" drivers on similar sized baffles. This requires fairly minimal EQ, too. At that point they're still clear and sharp, though their presentation is smaller than the 8"ers. They do, however, pretty much run out of steam around 50Hz or so, and if pushed to reproduce much of anything around or below that, they will distort. Just running out of Xmax. Pretty well behaved when they do, though. They don't try to tear themselves apart or really mess up the higher frequency reproduction much at all.
They sound great on these improvised baffles and non-optimized EQ stack using my newly acquired Panasonic SA-XR57 receiver's digital amplifiers. Lots left to improve and play with, though I have preferred all of my other speakers over my SI Gen2 T-amp, so I'm going to need to compare (or see if the T-amp can even get these puppies to bark at all), but that'll have to wait till tomorrow.

I'm almost done with a mini-tower center channel using four of these and a Neo3PDR. I too noticed they seemed a bit bright out of the box. After a few hours of play they mellow out a lot - break in is essential for these drivers!
I don't agree that these would be good full range drivers though. They are missing some high end that other 4" drivers do better and they have a noticeable breakup mode around 6.5kHz (ish, I don't have my graphs in front of me).
I don't think that the woofer you're talking about
(rs125 http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-360)
is the same as the woofer(s) initially mentioned...

You've got a neat project and writeup there tho!

You're right, I'm an idiot. I didn't think the Dayton full-ranger was out yet so I got sloppy with my RS names.
What size box for these guys ???
I'm pysched I stumbled apon these little speakers !
I would love to throw 7 of these together for my Computer surround project.
What size box have you guys used for these to get the best sound ???
any pics ??

Hey all,
Looking to purchase five of these to bolt onto the walls/ceiling for a 5.1 in an "infinite baffle" design.
Having a hard time deciding on the 4ohm or 8 ohm - as Qts varies from .82 for the 8ohm and .48 for the 4 ohm. Any advice?
I was going to use a Fostex FE127E, but these have better Qts.
Not too worried about sub 80 - 100 as I will have a sub.
Receiver will be a Panny XR45.

Also looking at the Hi-Vi M4N 4" too. High Qts at 1.08.
Would be real nice for whatever I use run full range - wired direct to the receiver

Actually, I am thinking of the Fostex FE-167E fronts/center and the FE-127E in the rears. The FE-167E spec at 50Hz to 22Khz - but a lower Qts of .31
After calculating the volume between two studs above the firebreak at 4 feet (this is an external wall), I get around 40 liters. I looked at the FE-167E and noticed Vas is 36 liters, so somewhat close for a sealed enclosure application.
The rears are on the celing and are open to the attic. I would thing the higher Qts would be more important on this installation.
Someone correct me if I am wrong.
The Daytons are still under consideration, but will they work well in a sealed enclosure is the question...
It's crazy spending over $200 for a pair of lame no- name brand inwall type speakers when you can get the Fostex drivers for a near perfect application.

Nope.
If you reread my post you will see that I was referring to the run of the mill, overpriced, IN WALL/CEILING mount speakers you find at Wal-mart, Home Depot, Costco, etc. It is these types (not the Dayton drivers) that are sold today as a necessary electronic commodity, like Romex copper wiring.
But then again, the average Joe Blow does not know the difference between these no-name brand speakers and the Fostex and Dayton.
A near perfect application for the Fostex/Dayton if you ask me.
I am a bit partial to the Fostex drivers as I have and heard them, but more than willing to try the Daytons as they may be even best the price/performance of the Fostex line.
I would consider larger drivers. 4in ones will be excursion limited, even when crossed at 100hz.
for IB home theater I'd use 8in full rangers.

Yup. me too.
I don't know if the 8" FR can do the upper frequencies as well as the 6" or 4".
I would love to not have a sub (wife hates it).

What about Subs is not to like ?? 🙂 is it just the fact its an eye soar ?
yeah 4'' does seem rather small for a HT settup though. But perfect for a computer surround settup 🙂
If and when I do my new HT 7.1 speaker build project, I like the "full range" drivers enough, I will definatly think about using some on the HT install as well.
But I have never heard a full range driver(besides the stock door speakers in my car) I'll see how the computer 5.1 project comes out and then decide...
Yep, among other things... And to get true music 2 channel stereo, you would need two. We can get away with a single sub with 5.1 movies, but 2 channel music is a bit different to me, requiring two...
The 4" full range cannot really compare with the bigger 8" full rangers on the low end. The 6"FR are just about perfect balance between the two extremes - strictly my opinion here.
Nice. Very good driver for this app...Qts is perfect for ceiling install at 1.07
