Zaph SR-71 question

FickleBJT · 5th August 2010, 04:22 AM

Hey everyone,

I just finished building a pair of the SR-71's by Zaph. I purchased the kit (without the enclosures...I built those myself). I have to say that the sound is wonderful. These may be the best speakers I've ever listened to, and my roommate has a pair of Advent Heritage speakers (which were previously the best speakers I'd heard).

One thing I've noticed however (and I'm assuming this is something I did wrong) is that the right woofer has some audible distortion that the left woofer does not. It seems to only be present (for my ears at least) at very low frequencies. Just before I put the baffle on I noticed that one of the two cross-braces had come loose (no idea how). I left it there before hooking them up. Could this be it? Or does this mean that some part of the enclosure is not sealed properly? Any ideas/suggestions would be much appreciated!

Thanks,

FickleBJT

Funny thing is that I've experience the same thing with my Zaph SR-71. I haven't heard it recently and so I am not sweating it - but still would be interesting to know what may be causing it.

Hi,

Swap the bass mid drivers around, if the problem moves its the driver, if
it doesn't then you've confirmed you have a cabinet problem to be sorted.

I did that and the problem moved with the driver, so I contacted madisound, and they're going to send me a new one. Thanks!

Hi,

Whilst your waiting sort out that cross brace, it cannot be working well.

I'm going to. Is there some way I could glue it in place without having to remove it from the cabinet? I have damping material glued to both sides, so removing it would be a pain.

Hi, you tell me, you can see it, I cannot, lots of wood glue ? /Sreten.

glue in a syringe? i've done this sometimes to get glue in tight spots.
