604B - Can I - Should I fix this?

**mattvandyke** · November 6th, 2012, 07:53 PM

This is a 604B that purchased about 2 years ago. I've built the Jeff Markwarts 604B crossover and I'm in the process of starting to build some cabinets for this and another 604B that I have. I'm going with the Stonehenge III cabinets.

Question, the HF horn in this speaker is not aligned with the woofer. Is this something that I could fix and/or should fix? The misalignment drives me a little crazy and I'm planning on keeping these speakers for a while.

Here is a picture of the front and back.

Your thoughts?

Not aligned in which axis?

Maybe the intention is: not concentric?

* Hard to tell with the shadows/lack of precise 'down the barrel' shot, at least for my eyes.

That would drive me crazy too! I would just go ahead and redrill the holes where they needed to be to align it correctly. I'm sure it's got to be affecting the stereo image being off like it is. How much, I don't know. That's my 2 cents...

Yep, I'd just redrill them too.

I would also add a few more bolts there. Hanging a speaker that heavy off of 4 mounting bolts seems risky.

The photos are so dark I couldn't tell much either. I lightened them up with photoshop so everyone can get a much better look at it but from the camera angle it's still hard for me to tell how far it's off. Regardless, even if it's only slightly off, it would seriously bother me as well....

aaahhh. I see now. yikes on the back.

If that's the way it was built, I'd leave it, it they were mine. Unless it's audibly noticable for some reason.

I don't think that they were manufactured that way, I think that when the woofer was reconned it was done that way. My guess however is that the entire speaker would have had to been taken apart to offset the speaker that much.

The woofer recone is marked WHF 5309 - any idea who manufactured this?

Luckily the other 604B has the original paper cone.

Thanks
