Do recones need a break-in period?

Thanks for the reply Cal.
GPA did the job so it was remagged for sure. I played it today as I was doing paper work in my office, with the loudness on and the bass boosted a little. Sounds pretty nice in the Tannoy Arden enclosures, about the same size as a 620 cab, and they bolt right in.
I did have to put the gaskets on the rear of the flange though, since I could only surface mount them.
The port is rectangular, about 16 inches across by 3 inches wide and ducted to about 6 inches in depth, making for more acoustic loading than I think a stock 604C calls for. The Tannoy HPD-385 15-inch dual concentric speaker has much springier, ie more compliant suspension so I would guess it needs different port dimensions. Please correct me anyone if my attempt at being technical has bombed!

PS Cal, if wiring them out of phase do you mean face the two 604 drivers up real close, like even bolted together? Sounds like it would really get the cone excursion really swinging, in synch but opposite, if you get my meaning. Great idea.

Are you guys SERIOUS - mounting them face-to-face?

Come on... ???

[Nipper]

I can see none of my speakers were properly broke in....

Mounting them face to face usually results in a lower SPL in the room. So you can run your annoying break-in tones longer, louder.

That's all.

Blankets work, too.

Good Grief!

I now have images of Charlie Brown in my head

I think break in for a driver is kind of silly. I can't see the surround or spider needing to wear in. If they do, it can't be much, and in order for it to be a true break in, it would have to break down and then plateau. Otherwise it would just be a steady degrading of the material and sound.

I've seen people test speakers and state that there was no break in period. I've never really paid too much attention if anybody has posted pre and post break-in graphs. If there is a difference, I still don't see any point in breaking the drivers in....... just listen to it. It's not like its going to go from finger nails on a chalk board to beautiful music. It's not going to be that kind of night and day difference.
