Magnapan LRS placement

Good news, yyzsantabarbara. Ayre tells me the VX-5 Twenty amp I propose to use will drive the LRS nicely, but I also have a pair of Parasound JC-1s sitting next to the Ayre amp if needed. As with the Reference 1 the LRS will be high passed at 80 Hz by a passive balanced Marchand filter and low-passed at 80 Hz by a Velodyne SMS-1 bass manager to a pair of HGS-15s. I use two speaker cables to each Reference 1, and propose to concatenate those cables for each LRS.

Those JC1’s would likely be the winner for my ears. This thing gobbles up power.

You may want to consider 50 or 60 for the cut off. The LRS+ can play low. I also have read other LRS+ owners doing the same.

The Ayre VX-5 Twenty is rated at 350 watts into 4 ohms with zero negative feedback.  The rated sensitivity of the LRS is 86 dB, 85 for the Reference 1.  Sources are Roon from a Nucleus and Ayre QX-5 Twenty and Blue-rays from an Ayre DX-5 DSD disc player, both through an Ayre KX-5 Twenty preamp.  I prefer a moderate listening level.  If I really like the sound I'll consider a pair of LRS+ with stands.

Not a good idea. they should be 3-4 feet from a wall in a symmetrical situation. The wall directly behind should be deadened with acoustic foam tile. The Ayre will drive them beautifully. That amp should be driving 3.7i or 20.7s Any dipole speaker benefits greatly from the use of subwoofers using a digital 2 way crossover crossing at 100 Hz 48 dB/oct L-R. You will get as much as another 10 dB headroom and much lower distortion levels.

mijostyn, I think I’ll start with the setup I propose: the LRSs 4’ from the wall behind them with the KEF Reference 1s interposed between them and the wall. The KEFs with their stands are a heavy lift for an 87 year old guy, but I might get the gardener to move them aside. The speakers flank an 85" Sony. The room's 13 X 19 x 8 with framed posters, bookcases, a pair of stressless chairs, and a desk and computer at the end opposite the speakers. If I use acoustic tile it will be on removable boards.

Given how satisfied I am with the sound using the Reference 1s I don’t want to disrupt the room too much just to try the LRSs.
