Default Pioneer A11EC80-02F 4.5 inch full range a

Is anyone familiar with this driver? It's the Pioneer A11EC80-02F.

I know that the 8 inch pioneer is pretty popular so maybe this one is not bad either. Hopefully someone with a lot more knowledge and experience than me can chime in on this one.

I just got this speaker the other day. I have small (48") tapered quarter pipes I put together to see if I wanted to build the 6 footers. Originally I simmed them for Fostex 127's but they seem to be doing fine with the Pioneers and at a good price.

The bass is fairly solid with only the kick being lacking for the most part. Bass guitar is there and discernible. They are a little raw on some of the guitar parts but I'm still adjusting stuffing. Vocals sound quite nice. I'm not sure about burn in but they already sound better than when I first hooked them up a week ago.

For scrap wood and 20 dollars they sound pretty good to me.

I hope I didn't get too technical with all the math and theory in the last post.

To me it is obvious that it needs some "coating" on membrane
Maybe some of this "tar" like stuff used on roofs
At this price you can allow yourself to experiment - who knows, it may turn out succesfull

Well said, I think the tweaks for the NSB's on Zilla's site would all be good for this speaker and I intend to try them and will post back.

The highs sound fine to me. But you have to remember that my opinions are qualified by the price of the speaker, for a 20 dollar investment this is a winner, and I got to check out my cabs. while I wait on the Fostex units.

Now to qualify my hearing. The specs say they go to 15K. I'm not sure what is actually up there but nothing appears to be lacking from the recordings I'm listening to, Pink Floyd, Pearl Jam, Green Day, some metal. I'm an old PA man so I might not hear it even if its there but those are my impressions from the first week.

I think this is a good speaker to experiment with and test cabinets, and its cheap!

I have microphones and PA run into my computer, does anyone know, and by this I mean have you used a freeware program that is easy to use to measure speakers? And yes I will post a pic.
