Martin Logan Motion Foundation B1 Bookshelf Speaker

Motion Foundation B1
Small in size but not sound, the most compact Motion Foundation model offers unheard of performance from such a versatile size.

The Gen2 Obsidian Folded Motion Tweeter S, Folded Motion Waveguide, and 5.5” aluminum midbass driver work together here to create a completely unexpected and engaging experience from a compact footprint. Foundation B1 is ideal for small spaces, especially when combined with a subwoofer, to create a highly musical, detailed experience wherever high quality sound is desired. Foundation B1 is also threaded to work with our STAND25 to create a stable stand mount solution.

Good unit, great sound and excellent set-up help for details not covered in the instruction manual.

These speakers were the perfect fit for my Atmos speakers in my 7.1.2 newly finished home theater. They not only have a high power handling rating, they have a very balanced, smooth sound. I have been so impressed with them that I purchased two more pairs to be used in other areas of our home. Highly recommended.

Love the speaker and great customer service

Works perfectly!!

This open box speaker is brand new, and sound quality is clear, which perfectly matches my Focal main speaker.

Excellent . Had a bit of an issue with the wireless connectivity but sorted that out with my service provider. Did open a case with Bluesound support which was good overall but they really did not attempt to troubleshoot. Just sent me some links . Back to the Node Icon a great streamer have used Quboz and Apple Music no issue and HI Res music is great on my vintage Marantz 2220 and Goldenear BRX speakers. I highly recommend the Node Icon. Also excellent experience with Safe and Sound quick delivery and will buy again from Safe and Sound.

The sound is amazing and the shipping was fast. I got the speakers the second day. Very satisfied!

Excellent streamer, pairs great with the Burmester 088 preamp. Love the EQ feature..

Better than expected, very pleased!

I had to build a wall to put the JBL Arena 55IWs in. After doing so I am very impressed. They measure very well, with no notable issues at the crossover point of the woofers and tweeter; and with them being in walls, they address a lot of boundary related issues in the 80-300hz region, this makes subwoofer integration better as well.
Thanks to Safe and Sound for the quick shipping and great price on these.

With my system, these speakers offer a soundstage with full dimension. The music is presented from above and behind them as if you might be watching a performance. The speakers disappear. They’re accurate to my ears. Not harsh. Solid articulated bass. My previous speakers did a lot of that, at different times. These are consistently a delight. Listening as I write…there it is…great bass.

Amazing pair of speakers, from their design to their versatility. Amazing price as well. Another great experience with Safe and Sound

The sound is sooo clear and clean that I was amazed !
I paired it with a 10inch Klipsch sub and the sound is sublime !!! It is well powered and fullfills every thing I wanted in a smaller stereo.
I have a large system with JBL 14’s and the old super tweeters with the old crossovers and I haven’t turned it on since getting this system. I LOVE IT TOTALLY !
100% I would buy another one, It is Great !
