Breakin question

Ideally, drivers are best run-in when mounted in their speaker boxes but I appreciate many Diyers like to break-in the drivers in the pack boxes to save time. This is ok so long as they carefully choose music with modest bass and keep volumes low. Watch out for power-train movements that visually appear to exceed 1mm on the draw stroke (cone moving inwards) during the first 100 hours. Ease back the volume, or change the music if needed.

Cheers
Mark.

glad to have you back at the keyboard Mark

Thanks Chris,
I'm around until this Sunday (3rd Feb), going into St Pauls hospital that evening. Surgeries on the following 2 days then recovery where I'll no doubt get bored quickly. I'll have my laptop with me and hope to posting again maybe by the end of next week (ish).

Cheers
Mark.

thanks Mark. Its clear to me now
i have already built vented BS boxes so breakin will be done in them.

I am glad that Mark has quantified "loud". 1mm. For me, 1mm is normal listing level for an A10.2. Of course, I don't listen to much music that is centered around kick drum, or the super compressed and clipped stuff that is passed of a music these days. I actually wound be listening to Vivaldi's "Four Seasons", or some of the other 8 concerti in OP 8, of the other 290 Vivaldi concerti/sonatas that I possess.

I am to the "Big 5" Russians what you are to Vivaldi. That has actually been of some concern in my migration to a true full-range system. Large-scale orchestral pieces are very challenging to even some large multi-driver systems.

I'm quite convinced that a FAST system is the real solution to my listening. I have some very good subs and, if necessary, some articulate 10" woofers to better cover the range between the subs and the A10.2s. My hope is to replace my current LARGE very full-range multi-driver system with a smaller Mark Audio-based FAST system at 1/100 the price.

Currently running a Copland collection CD to start getting some low-level bass into the drivers. About 130 hours of low-level music into the drivers.

Glad to help. My advice applies to both drivers being run in "free air - near free air" as well as in box. The main thing to remember is there's less risk of over-pushing the drivers during the run-in period if they're in a loudspeaker box.

Cheers
Mark

Hi Bob,
Know what you mean. Here's one of my likes (best played in a quiet moment)


Henryk Gorecki: Symphony No.3
Conductor: David Zinman
Performer: Dawn Upshaw
Orchestra: London Sinfonietta
Copyright Nonesuch Records (May 5, 1992)

Fab recording, Dawn Upshaw is pretty much perfect.

Cheers
Mark.

[phivates]

Is pretty much perfect. Indeed. Brings to mind a bumper sticker:
Art saves lives. All the ranting in the world comes to nothing when Ms Upshaw sings to us

[fastbike1]

For me, that symphony still seems to sound "the most right" with a Polish symphony.

Hard to listen to this piece without getting a bit emotional.
