A Subjective Blind Comparison of 3in to 5in drivers - Round 2
Default A Subjective Blind Comparison of 3in to 5in drivers - Round 2

The much awaited Round 2 of the earlier thread http://www.diyaudio.com/forums/full-...e-drivers.html now begins!

The contestants are, in no particular order:

1. Vifa TG9FD10-8 (fiberglass cone)
2. Tang Band W4-1320SB (paper cone)
3. Peerless P830986 (aluminum cone)
4. Fostex FF105WK (paper cone)
5. ScanSpeak 10F/8424G00 (fiberglass cone)
6. Mark Audio Alpair A7.3 (silver cone) (aluminum cone)
7. AHE 3in (from Taiwan) (paper cone) http://m.ruten.com.tw/goods/show.php?g=21206258966085

8. A surprise entry whose identity will be revealed after votes are in

Thus we have choices that will be randomly labeled A thru H.

Here is the photo of the entries for Round 2 (not including surprise entry).

Clockwise from 1 o'clock: W4-1320SB, FF105WK, P830986, 10F/8424, AHE, A7.3, and TG9FD (center).

Click the image to open in full size.

The recordings are of the same sound clips from Round 1, with the difference that a higher recording quality of 96kHz was used and the resulting clips are 320kbps mp3's with 48kHz sample rate. As usual, the same setup as the previous thread was used with respect to the speaker enclosure (trapezoid baffle Nautaloss spiral sealed TL) and XKi dual W5-876SE drivers for the bass. XO was provided by miniDSP with 225Hz LR4 and -3dB baffle step correction applied to all drivers. XY mic of Zoom H4 was set at 1m away. Source was high res files from Audacity played thru laptop for clips 1 and 2, clip 3 was from CD player. It should be noted that one of the drivers here (A7.3) received extra special treatment per the manufacturer's recommendation prior to being tested unlike all the other drivers which were tested as-is, straight out of the box, with no pre-conditioning. The A7.3 was subjected to a 200 hr break-in consisting of clip 1 music at low volumes for first 40 hrs, then progressively louder with clip 3 for 80 more hrs, then ending with moderate volume for 80 more hrs of bass line heavy track by Suzanne Vega ("Headshots").

Here is the first track for all entries (change the extension .asc to .mp3 to listen).

I will post the other 2 tracks later.

Enjoy!

I want to thank all the folks who were so generous in providing me drivers to test - this test and thread would not be possible without you.

Some of the drivers, I purchased myself this time though...

A reminder to not analyze tracks using software, and if you do, please keep it to yourself.


Answer key given in big reveal after votes were all in.

Thank you for taking the time to do this!
Clips A, E and D sound the best to me personally in that order.

For anyone feeling overwhelmed by number of choices you can apply some rigor to the selection process using the tournament method.

Please do listen to the Clip No. 2 - I noticed that folks are downloading 1 and 3 in greater numbers. Metal may not be your thing but this clips tests how the speaker sounds with very dry, non-reverberent source material with large dynamic range.

Is this relevant? Surely I'm listening to whatever I play back through?
