Wow, look nice for only 6.50 per driver!

How about pairing them up with the Vifa DQ25SC16 crossed somewhere in the 2750-3000 range?

That 4 Ohm impedance does make the mtm idea more difficult.

So how much fidelity IS the MAX amount of fidelity, anyway?

I have Audax to sell

I have a pair of the HP130ZO and a pair of the AP130ZO if anyone prefers the Aerogel cones over the paper. $5.00 each

Please excuse the thread hi-jack.

Measured the other 3 drivers tonight. It's about 10 degrees colder in the house than it was when I measured #1 Sunday. Also, drove #1 for about an hour with music. The other three I just stretched the suspension and measured. None are really broken-in.

Bought 4 of these Saturday and did some quick measurements.

Those are good looking response curves. How far were the enclosures from adjacent walls?

7ft to side wall, 4ft from back wall.

Forgot to note on chart that I did not apply any smoothing to the curves.

Thanks . I 'm in the process of setting up my own measuring rig. I will be using a M-Audio Fast Track MKII USB sound card with the Dayton mic. With a usb sound card I can use my laptop or any other computer I chose. What type of setup are you using? I forgot when measuring speakers in a box baffle step compensation isn't necessary. Is it better to measure speakers in their boxes rather then on an infinite baffle?

I think their specs are very consistent, thanks Mark
