During a local store closure (move out sale) I picked the following Martin Logan Motion speaker configuration for deep discounts as these were floor models:
Talking to someone with tons of knowledge about speakers I was advised that I should have picked Martin Logan Motion 30 for center speaker instead of Motion 8. Unfortunately the store didn't have floor models for ML Motion 30. I am a newbie and definitely nowhere close to an audiophile so my question is:
- Martin Logan Motion 40 standing speakers
- Martin Logan Motion 4 bookshelf rear speakers
- Martin Logan Motion 8 center speaker
- Martin Logan Motion Dynamo 500 subwoofer.
- Does anyone have a Motion 8 center with Motion 40 front speakers? What is your experience? Or is this a bad idea?
- Since they only have new Motion 30 speakers, if I return the Motion 8 and get a Motion 30, I would have to shell out $400 more. Is it worth the $$ or should I stick with Motion 8 for center? (remember I am a newbie with home theater systems so I don't know if this is an overkill).
My first introduction to MartinLogan speakers was by chance ... my son and I were at the local audio store to listen to some other speakers - James was in the market for bookshelf speakers and we listened to a pair of Motion 15s and a pair of Motion 4s.
The difference between the two speakers was clear enough immediately that I knew right away that I'd be buying him the Motion 15s.
I'd venture to guess that the difference between the Motion 30 and the Motion 8 is similar.
The Motion 30 weighs in at 18 lbs while the Motion 8 weighs a mere 8.5 lbs.
The Motion 30 has a pair of 5.5" mid-woofers made of the same material as your Motion 40s ... the Motion 8 has a pair of 4" paper cone mid-woofers.
While researching center channel speakers a year and a half ago, I came across the topic of "lobing" ... in short, this is an effect that many center channel speakers exhibit where the speaker's sweet spot ends up being a very narrow one.
I called ML about this, explaining that I was interested in the Motion 30 ... they said that they designed the Motion 30 with two separate crossover points to remedy the lobing phenomenon.
One of the Motion 30's mid woofers works only up to 400hz, the other one crosses over to the tweeter at 2,600hz ... the Motion 8 has only one crossover point, and that's at 3,000hz.
The Motion 30 is a nice and compact speaker - only 16.5" wide, while the Motion 8 is over 22" wide.
IMO, the Motion 30 would be a good long term investment, whenever you are able to afford it ... I'm guessing that it's within the financial realm of possibilities since you are asking about the Motion 30. I'm quite pleased and content with mine ... I'm sure you would be as well.
The Motion 40/30 combo provides a seamlessly blended soundstage ... and remember: for home theater, the center channel is as important as any of the other speakers - the dialogue speaker.
For music, it's also an important link in the chain, so to speak ... I listen to a good amount of music through my USB input, and I always use the "multi-channel stereo" mode offered from my AVR ... my Motion 30 more than holds its own between the Motion 40s and my LX16s.
Good luck with your decision :-)
