Dayton 295-305 (6.5" Woofer) problems?

[jsd]

Has anyone had any problems with the Dayton 6.5" Woofer part # 295-305 from Parts Express? I bought 4 of these a few months ago. I recently took them out of the box, and hooked one up to my amp. It sounded pretty quiet, so I hooked up one of those 87 cent Pioneer 4" full rangers. Wow. The Pioneers were a LOT louder than the Daytons, whereas the Dayton should be 87dB 1w/1m, and the Pioneer 86dB 1w/1m.

We're talking the volume all the way up on the amp with the Dayton gave me the same volume as the Pioneer at half volume. It also sounded like it started to distorted at a low power level (that's saying a lot considering the Pioneers are only rated at 5w RMS and 10w peak), and response past around 500Hz was VERY poor. I realize that it won't go very high, but it should be able to go to 2kHz no problemo, right?

What's going on here? I emailed PE.. but am I right in believing that the higher frequency response should be a LOT better? I loaded up winamp, popped on a song and set all the sliders past 600Hz at 12dB down, 600Hz and lower at 12dB up, then a 12dB overall cut.. I then swung from left to right on the balance slider and the Dayton sounded like crap.

So then, I loaded up WinISD, and set the volume on my amp. It has a seperate volume control for each channel instead of a volume control and a balance control. I set the tone generator for 600Hz, and matched the volume as close as I possibly could. Of course, the Dayton required significantly more in the volume department to get the same sound output.

I rose in 100Hz increments, and found that the Dayton had just about nothing past 1.5KHz.. eh? That's pretty bad!

This doesn't seem right at ALL considering people cross these particular speakers over at 3KHz!

Ideas? Bad batch of speakers, or what?

Is it just one or all 4?

Very different drivers, the Pioneers have loads more output
above 1KHz, where sensistivity rises to 90dB/W with a
98dB/W (!) peak on axis at 6kHz, extend to ~ 15KHz.

The Daytons have far more low bass, which you can't hear
out of a box and a subdued roll-off above 1KHz to about 3KHz.

I'm not surprised the Pioneers sound much brighter.

It is accepted the Daytons forte is good bass
not midrange, here its crossed over at 2KHz.

Well, like I said it sounded like it was distorting at a pretty low power level, and around 400Hz the Pioneer was much louder.

So far 2 out of the 4 look the same, I haven't checked the other two..

And what about the lack of response above about 1400Hz?

You're comparing apples and oranges. First things first, put both drivers in enclosures of appropriate size. Then feed them both with program material that is fairly representative of a real world signal, ie, pink noise. At that point you'll be able to tell the real difference between the two drivers, most of which will be below 100 Hz.

Testing drivers out of enclosures is a risky proposition, as you can easily put enough power into them to blow the voice coil while having little acoustic output.
