Dayton DA135-8 5.25"

type · 14th April 2006, 04:38 AM

I was just checking out the drivers at parts-express and noticed that the Dayton DA135-8 5.25 inch woofer (part # 295-330) has a frequency response of, 50-15,000 Hz. Could this driver actually be used in a full range application?

Here's a link to the driver:

These are the links to the specs at PE's website:

Hmm...I've never thought about using the Daytons as fullrangers. The main problem why aluminum cone speakers usually cannot be used for higher frequency lies in their break-up nodes. However, looking at the cumulative spectrum decay graph of the DA175 at Zaph's site (www.zaphauiod.com), it looks like the resonances aren't too bad. The distortion figures are also within acceptable limits. I suppose the DA135 isn't substantially different from the DA175. The DA135 has a resonance peak at 9 KHz so my suggestion is to use a notch filter and listen to the result! If you try it out, please let me know! By the way: Keep in mind that these speakers have a bad dispersion characteristic, so listen to them on axis!
