Default Crossover Frequency Measuring and Midbass Suggestions

Good evening,

So I have some old car audio components, that I built boxes for. Elemental Designs 6500 edi, if recall correctly. 6.5's. The boxes are sealed. Anyhow, they sound great, but sadly I'm getting a buzz in one of the midbasses so I'm going to have to get a new pair. Everything is 4 ohms. I've been reviewing and reviewng various choices, and would love to hear suggestions. I'm on a tight budget here. Really need to keep 'em below $100ish for the pair.

My issue is, I have no idea the crossover point on the passives. Apparently Elemental Designs went the way of the Dodo a few years back. Is there a way to measure something on the crossovers to reveal the crossover points?

I'm excited to hear what those more knowledgeable than me have to say.

Thank you,

Arthur

Why not look at repairing what you have first ?

A buzz can be a loose dust cap or a tinsel touching the cone.
If the driver is one of the 'woven' styles it can also be loose strands of the cone.
Maybe a loose screw, or something in the cabinet.

A fix could be simple, and far cheaper than trying to replace it.

Not a terrible idea. I'll look into it. I tried cleaning out between the former and phase plug with a sheet of paper, that seemed to help but then I could hear the buzz again. They're really good sounding mids, so I'd love to save them (and the $$$).

The 6500 midwoofers without the phase plug look VERY similar to the classic Vifa P17, especially the magnet and frame, but it looks like the 6500s are coated paper instead of polypropylene. However, I'd bet the P17 would be a good replacement.
