I made an extremely important discovery about the LRS ......

I raised the LRS 8 inches off the floor as an experiment today utilizing a pair of 20 x 20 x 8" cardboard boxes

I was amazed at the extreme increase in bass output

they also have more extended bass

there is almost too much base now !

The soundstage is much bigger

the change was much more than I was expecting - I need to live with them a few days to decide if I love the tilted sound profile

maybe some othe LRS owner can try this and give some feedback

the Norah Jones record now has a much more solid underpinning of what I think is a double bass ,,,,,,,

So are they vertical now too / or still tilted but 8" off the ground?

Ok - now we are getting to the meat and potatoes

On Blind Boys of Alabama the song " Jesus gonna be here- gonna be here soon "

The upright acoustic bass is much more palpable - now with proper size to fool the mind

surprisingly I hear no difference in the mid range or treble

the sound stage is not enlarged in proportion to the 8 inch added height but surprisingly there is a notable increase in width

they are tilted and 8 inch off the ground as measured from the bottom edge of speaker - they might be even better if they were 90 degree perpendicular to the floor

the practicalities of tying that while on a make shift cardboard box pedestal are more than I want to risk at the moment

the distance of my ears to the ground now represents the mid point of the driver - almost exactly

that might mean that the waves jumping out of the driver are at an optimal wave form - or I could just be full of doo - doo on this

Ok on this one the improvement is ridiculous

as a point of ref - I am no hack here

I heard this record played with a 10 grand analog front end - 45 rpm direct master record into a custom made Japanese hand wound field coil compression driver system $$$$$$$

My MagnaRiser MK 7 Multi Riser stands have 2 different height adjustments.

To say I'm pleased with them is an understatement.

MAJOR improvement...

I would advice to keep the space between the speaker and the floor closed, it helps the bass response.

" By getting the panels upright and off the floor, the overall musical presentation is remarkably enhanced, to the point that the LRS is virtually transformed, and is now no longer simply an entry-level gateway to Magneplanar's more expensive offerings: they can easily compete on an equal footing with higher-priced Maggies. The audible improvements the Airborne stands help bring to the LRS are not subtle; they truly eliminate or help ameliorate virtually all of the initial problems I found with the LRS's playback abilities. Adding the Magna Riser Airborne stands helps the LRS sound more like a much more expensive pair of loudspeakers than the mere $650 they retail for. "

I used a pair of Magnarisers on my LRS before trading them for a pair of
1.7s. I am somewhat dis-satisfied with my 1.7s. Maybe it's because I
do not have them properly positioned. I think the LRS gives a "livelier"
pesentation and the soundstaging - which I'm big on - is much better.
I will be diddling the positioning of the 1.7s fairly soon so maybe
things will improve. If not, maybe I'll go back to the LRS.

Life is hard. It's harder when you're stupid.

The benefits of raising the smaller speakers off the floor we used to talk about here on the Planar Asylum twenty years ago. :)

thats wonderful - has there been even one thread about the LRS and the optimum height to raise it since it was released ?

Seems my suggestion was close to what you found worked well.

You didn't lose bass at all. :)

I would definitely agree 100% with that.

We were talking MMG's back then, but everything applies to the LRS as well.

'Very simple concept to put the center of the transducers at ear height and bring the speakers to vertical. This is an old concept but it's only receiving attention lately because we have an aftermarket product with catchy name exploiting it.

Is there ANY loudspeaker that wouldn't benefit from having its transducers brought up to ear height? Or is this a classic example of reinventing the wheel?

Generally, the listener should be on the design-axis of the speaker.

Notably, this is still the case with MMG/LRS's on the floor but tilted backwards in the stock configuration.

I don't think we can say that raising the speakers from the floor boundary will be beneficial in all cases. There are too many variables and reverberant factors at work. Always there are trade-offs with speaker systems and their placement.

Dave.

I imagine there's a good reason why listeners put stacked quads into a variety of different rooms. :-)

Wherever they are, you have to be centered on the vertical axis or you'll lose HF response. In practice, that means they should be tilted back some, unless they're up high enough so that your ears are centered vertically on the tweeter. If you raise them too far, you may lose bass extension.

I recall having auditioned B&W 800 D3's ($15,000 apiece) in one of my Maggie dealer's listening rooms. I didn't particularly enjoy them as I thought they were too close to the floor. For one reason or another the salesman (knowing I owned Tympani IV-A's) seemed to understand why.

The sound from speakers near the floor sounds too low to me. This was very pronounced with the MMGs.

After reading your post I decided to raise my .7s while I'm cleaning the extra pets that grow from dog hair and I'm getting the same thing with the bass, soundstage, and overall sound quality. Wow! I kept checking to see if my sub was somehow working in Pure Direct on my Denon. LOL. Right now they're ridiculously too high. Time to build two risers.

At my visit to the Magnepan factory, these were the only ones that they could demonstrate, in the entrance hall. Double set of LRS or LRS+, not sure which. The DWM was not used. Not much lower bass from this set.

"Excellent! :-) Really improves things, doesn't it."

I did a lot of listening yesterday and they sound like different speakers. Really impressed. Just have to decide on height I want to settle on and start building.

I'm having someone make the risers but not sure what I should fill them with if anything. I can't quite get an answer searching it out.

Massive and rigid and damped are all good. If the tubes are hollow and you're ambitious, you can fill them with sand.

I've never heard of them being doubled up that way. I'd expect more bass output because of the wider baffle, but the resonant tuning would be the same, so I don't think they'd turn into 30.7's!

Ok thanks. Pics and review at new height when I get it all set up.
