Be sure to post the "Image Link" that ends with the file extension, i.e. ".jpg" or ".png" depending on the type of image.  

The "Direct Link" you selected, the one without the file extension, will not work in this forum.  I did the same thing you did initially and had to do a little trial and error before figuring it out.  You are almost there!

'course, I was gone last year, too.

Thanks Raven,

I don't know if those charts are good or bad, but the low frequency has certainly smoothed out since the last time I measured.  Same for the high frequency so I'll try to post that as well.

Maybe there is something to this room treatment thing Wink

I do know that the room/system sounds it's best yet.

Just as I got a nice lift in the highs from the AMTs (on sale now BTW), I am now experimenting with filling in below 50hz with a sub.  I have never been able to integrate a sub well in the past, but that was when I was trying to cover more ground.  The Augies do the heavy lifting now, so just like the highs I am only using the sub to sweeten the lows.  It is showing some promise.

I'm using a Dayton Audio Reference series 15" driver.  Nice tight sound to it.  No blob or boom here at all.  Around $175 which doesn't break the bank.

the link to imgur worked for me... perfectly.  Browser and/or browser settings likely the culprit. this forum and Chrome are flaky for me - but IE seems to work flawlessly most of the time.

I built a solid box for my sub experiment this last weekend.  3/4" MDF 19.25X19.25X20.  Well braced, double front baffle.  Weighs a ton.

But I must say I am happy with the result.  The Augies are a fantastic driver, but they fall off under 50hz.  This sub definitely fills in and makes certain music more enjoyable.  I was surprised that it lends definition to the bass in a lot of songs.  But you can feel it on those with the low low bass.

I was also pleasantly surprised at how well it integrates.  I have the crossover set for about 45hz and it really blends.  Raven gave it a listen and felt is was just a bit off and that I should experiment with the position a little to get it the last 10% or so.  I literally put it where I had room so I haven't played with it yet.

They recommend 1000 watts to drive the 15" driver but I am more than adequate with a Dayton Audio 250.  I'll experiment with more powerful amps, but so far so good.

As you can tell, the Palomino Audio Project has completely jumped the shark.  I am quad-amping now.  

The heart and soul is my black top Rachael but I am using bridged twin Crown XLS1000s for the right and left Augies and the plate amp for the sub.

I think the next turn will be to look for a new mid range driver.  Using the Tang Band now solely as a mid range driver probably isn't the right way to go and as Raven pointed out in the last mini CDApS, there is an edge to some vocals.  Randy's whizzerless Betsy is a possibility, but it doesn't quite fit in the third iteration of the PAP baffles and I hate to toss them.

If anyone has an idea on a good 8" efficient mid range driver that I could cross at about 12K, I am all ears...

I tend to think we came to the same conclusion independently here Cheesy

Here is the 8" driver for you.
https://www.parts-express.com/grs-8fr-8-full-range-8-speaker-pioneer-type-b20fu2...

These things are stupid good for $12.
My latest build is a transmission line using 2 of these in each box. I'm having a hard time putting my OB's back in. It is kind of silly fun.

For that price, you could make a crazy line array for under $300

For fun, I created a template that allows me to put my Silver Flute 8" 4 ohm drivers into my OBs in place of my Tang Bands.  These are the drivers in the DM 945 speakers.

Sensitivity matches up with the AMTs and I am using the same cap value which crosses at 12K.  Basically this is the 945 sound in an OB platform except a dipole AMT tweeter (which I love for conveying the room sound).

So far, I am impressed.  A little warm, but very nice.

Hmmm Palo, I have a pair of those also. In fact I'm listening to them right now.
But I'm still recommending that you try some of the cheap 8" GRS Bofu clones. For less than $30 a pair, you have very little to lose.

In checked those out Donnie.  I especially like the example where the guy put a bunch of them in a cabinet for his car.  

But they don't match the efficiency of the AMT (94db) and that would require more of an xover and I am trying to keep this to a single cap.

I'll keep looking but this driver sounds pretty good.  I may also try the 945 tweeter but it's not dipole.

If you're home today (Wednesday) I can swing by after work, pick up my little Zen amp and give it a quick listen?

I'm not sure I can take any more of a beating.

I will be home around 6:00 if you want to swing by.

You could also pick up the tape deck which would give you an excuse to swing by Steve's. (although I do think he will keep this close to the vest)

I switched back to the Tang Band W8 1808 from the Silver Flute.  I believe the Tang Band driver images more precisely and has more soundstage depth - even it is forward sounding in comparison to the Silver Flute.

The Tang Band also has less of a pinned to the speaker sound on those tracks that are very left/right centric.  You know, where there is no disappearing act for the speakers.

I will pop the Silver Flutes back in at some point, but for now, I'm saying I prefer the Tang Bands.

There has to be another solution. Especially if you're running those AMT tweeters. We need to find a fast driver the compliments them well.

Pal...check out the new 8in drivers from Acoustic Elegance (94.6dB).  Note: I am sending you their Facebook page vs. website, because I remember reading the website was hacked recently.  

Also worth noting, if you expand the comments for the new drivers they are working on a finished open baffle speaker (similar to the PAP design).  Their dipole woofers get good reviews and are used in the higher end Spatial Audio OB's, so could be an interesting option for the non-DIY crowd.
