Bloke on another forum says needs speakers for a big room. Posts picture of room and it's beyond a joke. I've been in cathedrals that were smaller.

I looked at that last night - yes indeed, quite a room, wonder what the rest of the house is like.:scratch:

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! :lol:

That ChatGP is just a glorified search engine dunno what all the fuss is about.

I'm looking forward to hearing the LX521s again.

I don't think there will be a problem with SPL unless the room is packed with people. Might be a good idea if everyone brings a blanket or a rug along so we can damp things down a bit if needed.

Indeed, we need to get inventive. We've been here before. once at the airport hotel and also at The Wellington pub. We will sort the room. Its a great space for us to work with.

I've just got an email from LNER saying their are strikes on the Friday and Saturday which is when I was coming up. Not looking good as they've withdrawn ticket sales on those days. I'll update when I hear more.

I thought you were organising lift with Mik Rik? Are you now travelling from south?

Yes getting a lift on the day, but I need to come up from London on Friday to get there.

Megabus! But you'd probably have to set off Wednesday to get there on time :(

I'm afraid my sympathy for train drivers left me a while back. Very sad to hear this Lawrence. The bus is an option but it would spoil the day for you methinks. Its a good six hours on the National Express.
