I just got a REL T7/x and I have 2 weeks to figure out if I can make it work properly in my room or return it. However the unit is not run-in, so it will need a couple of hours playing at high volume.
My idea for running it in is to connect it via the (low level) sub-out of the SN2, disconnect the speakers and let it chuff along happily for a couple of hours.
Is there any risk of damage to the SN2 by doing so?
To give some background, I purchased the REL at a very good price as it was a return from another customer. So it must have been used for a few hours/days already. The dealer still allows for returns within a 14-day window. So it will be “my” REL if I make it work satisfactorily.
That said, the official run in process is given here:
You could disconnect the hicap output to the power amp, which you would legitimately do if using a separate power amp and the supernait as preamp only, so I don’t see why not. This doesn’t switch off the power amp, it’s just not being used. It’s probably easier to disconnect one end of a snaic than it is to pull 4 speaker connections.
Just use it gentle first and let the amp get use to its driving balance too.
Gently then a bit more but don’t go silly.
Can’t think of anything happy being thrashed from a standing start.
No point running anything in different to how it’s going to be used.
I’ve found some speakers, especially their LF drivers, to require a run in period after being unused for a while. In particular, the large passive bass drivers on my Shahinian Arcs seemed to require this. I bought them ex-demo and was surprised to find that there was NO bass to start with. It took about 10 days for them to gradually loosen up and work properly.
Not so according to REL. From their break-in instructions:
Don’t think that playing a good sub at modest levels for a year will accomplish much in break-in. While the amplifier will be stable, the driver won’t break-in and seat properly. Maybe with heavy, slow old tech woofers this worked but not with modern, lightweight cone/voice coils.
In any case, I’ve been warming up the subwoofer at a low level for the past few hours, and I am not going to shock it at full blast any time soon. But I will leave it reasonably loud (~11 o’clock volume at SN2) later today while I am out playing in the snow!
I read all advice and consider it carefully. And I am grateful for the time you take to respond.
But if the manufacturer themselves state something contradictory to your advice, am I not allowed to mention it?!
Subwoofer in two-channel is a different discussion altogether, let’s not get there. Many people seem to be happy integrating RELs with their stereo speakers. I should have an informed opinion in a few days.
