Probably the A6.2P or 6.2M would be better candidates for FAST... if you have any option of choosing, maybe do the smaller drivers first?
You are going to be disappointed with the A7P. It has a huge distortion peak around 600Hz. As much as I like the A7.3(M) and the A10.3(M), I can't warm up to the paper drivers.
YMMV.

Beatles, Simon and Garfunkel, America and the like - all beautifully rendered with this speaker. It needs juice tho so feed it what it wants. My little Topping just barely makes the grade. I'm imagining 4 of these little drivers clustered in the center (two over two) of the 18" x 18" baffle for increased efficiency. Stairway to Heaven gave me goosebumps.

Nice! Not bad for a $12 TV speaker as some like to call them. With four in series parallel you will buy more sensitivity and lower distortion so higher SPL. Maybe arrange in a diamond? You might get some lobing in near field though. I really like just two of them - quite good at 91dB at 2.83v. The 40 watt TPA3116D2 amp powers this driver very nicely - just about as much power as it can take.
Here's another fun test related to this thread. Though honesty is required in this case;o)
Made it yesterday with my "Maclaptop" and "highly acclaimed" Koss UR 40. 5 wav files nailed and 1 mp320, Jaz Z was the culprit though Coldplay production was difficult bad also.
Have fun!

Thanks for the link Peterbrorsson! What is interesting is how difficult it was to tell the difference on most of the clips. Perhaps they were not the most ideal locations in the track for critical comparison, but I admit that of the 3 I listened to I got 1 out of 3 right - and it was a track I know well. The Suzanne Vega song is the mother of mp3 and was the basis for the psychoacoustic studies performed by the Univ of Brandenburg in researching how to effectively compress music so that the majority of people cannot tell the difference. The technique of masking all info below 13dB around a 10% wide frequency window of a dominant tone was based on psychoacoustic surveys. Most people cannot hear sounds within a 10% wide frequency window of a dominant tone if it is 13dB below the tone, the so called "13dB Miracle". That and breaking the sound into 32 overlapping sub frequency spectral bands for the FFT (sounds is stored a string of 32 FFT coeficients) are the basis for the 10:1 compression ratio. And you know what, it works! Take the survey and be honest and tell us how you faired. Not any better than guessing - it was true for me because I could not hear the difference in the processed and compressed pop and hip hop songs. I used 2-way balanced armature in ear monitors and my PC laptop.
I would be interested to see how memeber Jay (aka Golden Ears Jay) does on this test. 🙂
I used a trick I've learned in my daily bread'n'butter gathering. I'm matching colours quite often and taking too long time to decide what's going to be done, is screwing up the final result.
It seems to work for listening also, I just switched back and forth between two clips and decided quickly which sounded most relaxed and least strained.

Just had a listen with my headphones plugged into the computer.
The first two were easy ... music seems to open up when uncompressed.
I got a couple of the remaining 4 but it wasn't so easy as the music clips didn't really make the uncompressed shine over the compressed files.
I have some mp3 and DSD files of the same songs, and they really don't sound the same. Sure, for background music that you listen to while working or exercising, mp3s are fine. But when sitting down in your listening sweet spot, in front of your nicely tuned DIY speakers, uncompressed is much nicer than a mp3 file.
Would I be able to listen to mp3 files only if that was all I had? sure.
Do I enjoy the spaciousness that uncompressed files have? You bet.
So, I'd be happy either way. Just being glad there's music in my life. But the little extra makes it all so sweet.

I took this test when it first appeared on the PETT. Result was that I cannot tell the difference between 320mp3 and wav; chose one or the other of 4/6 tracks. On the two rock tracks, I chose 128. Go figure.

Bob, did you use headphones? Personally, I find it unlikely to detect difference between 320 and wav using loudspeakers and listening to whole songs…...
I used speakers. I don't like the presentation that cans give and will never be using them for any serious listening, so it is a moot point.
Typically, I can tell the difference between 256 and 320 MP3. I find it difficult to tell 256 AAC from 320 MP3.

Ok,
Funny is that my cheap Koss phones are quite good at avoiding the "in-the-middle-of-head presentation. My Grado's are worse in this aspect.

Found a unique Full-range driver
First of all, thank you for all your work, especially your "Blind Comparison" threads. This type of educational information is sorely missing from diyaudio.
Anyway, i was browsing different full-range drivers made by manufactures, trying to find one of my favorite full-range drivers that i bought years ago in a set of cheap computer speakers that have long been discontinued (Sony SRS-DB500). You see, this was my first speaker, but even after trying many expensive speakers and headphones (Paul Carmody's Amiga and Overnight Sensations, Pioneer SP-BS22LR) i still thought that my old cheap Sony's sounded the best.
Long story short, found out that the drivers are super cheap (but fantastic sounding!) Visaton F8SC's. Some lurking on Visaton's website show that they are a "budget speaker". Some more lurking and you find that Visaton produces a 3.3" speaker that they advertise as a "HiFi" Speaker, the FRS8. The frequency response for the 4Ohm version looks promising too!
Best of all, i found out MCM sells the speaker drivers for about $11 each. 😱 The 4Ohm is currently sold out, but the 8Ohm is available.
Ill let you know if i buy a pair of these and test them out. I hope you test them out (and hopefully love them) too! I'd love to get your opinion on them.

This one is better according to me. Heard them both at a Visaton dealer when picking up other drivers recently. It has stronger motor and flatter response.

@xrk,
Hmm, maybe should have sent you FRS8M instead. It's not beaming as much as B80! Look at the directivity pattern further down…
B 80 - 8 Ohm
