I looked at that last night - yes indeed, quite a room, wonder what the rest of the house is like.Originally Posted by Macca
For a bit of fun I thought I'd ask ChatGPT how the LX521s would fare in the room at the cricket club. I'd already asked it about the speakers and it gave a 100% accurate account of how they worked, that they were active dipoles etc, etc so that was quite impressive.
Here's the answer it gave regarding use in that room:
"The Linkwitz LX521 loudspeaker is designed to work well in a wide range of room sizes, including larger rooms like the one you've described. However, the performance of the speakers will depend on a variety of factors, including the layout and acoustics of the room, the placement of the speakers, and the specific equipment being used to power the speakers.
In a room as large as 375 cubic meters, it's possible that the speakers may struggle to fill the space with sound, especially if the ceilings are high or the room has an open layout. To compensate for this, it may be necessary to add additional speakers or use a more powerful amplifier to drive the speakers."
Well, not bad, but the suggestion to use a more powerful amp tells me that it doesn't really understand that the LX521 will actually be limited by cone excursion in that room, way before amplifier clipping. It only takes about 100 watts at 30Hz to push those bass drivers to maximum excursion (56mm) even though the drivers themselves have ratings of 250 watts continuous and 500 watts peak.
Anyway, in that room we have a blank canvas to work with so there's the potential to make it work really well as long as we don't expect high SPLs sitting 10 metres away. At home I'm usually complaining about sidewalls that are too close, can't get the speakers far enough apart etc, so no excuses on that front with this room!
