Speakers - Running them in?

[( |-| |2 ][ $]

Is this required, can I expect the performance of brand new speakers to improve after time?

The reason I ask is I've owned a second hand pairs of Mission 773e's for a year now, I've always thought they were good but lacked a little on the bass.

I've been saving for some B&W 684's or similar for a while but after hearing my brothers Wharfdale Diamond 10.2's I thought the 10.4's (2.5 way floor standing version) would be great stop gap.

Just unpacked them and compaired them back to back against my Missions and if I'm honest I'm kind of hoping there's an invisible brick wall I can remove from the front of them...

Am I disappointed too soon?

Perhaps both speakers are telling you the quality of bass coming from your source and amp is the problem. Bigger and better speakers need better signal fed to them, or the sound gets worse not better.

I'll willing to accept you could be right. (any excuse for a new amp).

I'm currently using a Cambridge Audio A400 which should be plenty powerfull. I could understand a better amp helping with the bass on my Missions, but the bass from it on these Wharfedales is plenty, it's the treble that's lacking on these, but is crystal clear on the Missions.

Thoughts?

Here's what they both look like btw.
