Here’s a review of the LRS from Steve Guttenberg/Audiophiliac from youtube.
https://www.youtube.com/watch?v=gdqchci3AhU He does talk about the differences between the LRS/.7/1.7 models, mainly stating the LRS is Magnepan’s ’appetizer speaker’ and , at $650/pr, an excellent and affordable way to experiencing the open, articulate, transparent and palpable sound with excellent but limited bass response. He mentions how moving up the Magnepan model line just gets you more of this sound, beginning with the .7 and 1.7 which he describes as being taller, wider, more expensive versions of the LRS that sound warmer and have a bit more bass.
He also discusses the difficulty of integrating subs with Magnepans, stating he really gave up trying to integrate subs with them when he last tried when he owned a pair of 3.6s. I understand his frustration after experimenting for a few years, at first with a single sub and later with dual subs, trying to integrate the bass seamlessly with my older 2.7QR 3-way Magnepans.
Changing from a stereo class AB Aragon 4004 MKII amp (400 watts/ch at 4 ohms) to a pair of D-Sonic M3-600-M class D mono-blocks (1,200 watts/ch at 4 ohms) significantly improved the bass quality, power and dynamics of the 2.7QR’s rather large 623 square inch quasi-ribbon bass sections but the bass extension is limited to about 36 Hz.
I completely understand why Magnepan owners love the performance of their speakers, regardless of model, and are willing to sacrifice powerful, extended and dynamic bass response rather than do without the excellent performance of them from the mid-bass on up as well as the exceptional sound stage imaging.
But I’ve also discovered that experiencing even just most of the bottom octave (16-32 Hz) on music and ht is immensely enjoyable mainly because I perceive both as more realistic. I’m not a Bass-Head but I admit I enjoy the bass weight and power that viscerally involves your whole body in the music or ht.
My main intention of posting on this thread is to spread the word that there is a proven method, based on scientific research and psycho-acoustic principles, to seamlessly integrate powerful, extended, dynamic and articulate bass response with the excellent frequency response of fast Magnepan planar-magnetic and electrostatic panel speakers.
I’m a bit amazed that there’s not more awareness of how well 4-sub distributed bass array systems perform, especially on high quality audio sites like Audiogon and Audio Asylum. I find this lack of awareness of dbas to be unfortunate and perplexing. Here’s a link to an Absolute Sound review of the Audio Kinesis Swarm dba system that I think describes its performance and benefits very accurately:
www.theabsolutesound.com/articles/audiokinesis-swarm-subwoofer-system/ I don’t want to be a distraction to the main subject of this thread out of politeness but also because I’m very interested in the comparisons and performance reviews of these 3 least expensive Magnepan models.
I’m very intrigued by the the overall system sound performance prospects of combining the excellent performance of the Magnepan true ribbon tweeters for treble and the quasi-ribbons for the mid-bass and mid-range with the only qualities I suspect are lacking in all of these models preventing state of the art performance; excellent powerful, dynamic, articulate, extended and seamlessly integrated deep bass performance that I’m certain a dba system would provide.
While it could be true that my words describing how exceptionally well the dba concept actually works may have convinced no one, I truly believe even a brief dba audition would likely convince virtually everyone.
Enjoy,
Tim
