I am seriously thinking of taking my Progmeister specials (Speakers) depending on my son wwho will need to help me get them there and back.

Are they the Kralk ones? I'd like to hear those.

Alan built mine to order based on his V200 design.

Alan built mine to order based on his V200 design.

Those V200's are very big speakers, I have the burr oak AR10's shown on Alan's website which look tiny next to the V200's. I will definitely look forward to hearing the Progmeister specials if you take them.

A quick update gentlemen. I visited the Synthonia cricket club on 29:04:2023. I met with Norma who is the link person for the hiring of the room and facilities. I was joined by fellow Neboite Gordon Halftree to give a second opinion on the room. We both agreed that although it is on the large side we can work with it. The cricket club fulfils 80%-90% of our criteria which is more than we can expect given the short notice of having to find a new venue.
The Synthonia club like our previous venue doesn’t provide food so I intend to visit the surrounding area seek out food options like Pizza delivery, food shops, cafe’s etc. Norma has no problem with us taking in our own food. There looked to be a reasonable choice of ale and booze. Pumps for John Smiths, Bier Morreti, Strongbow cider (original and dark fruit) are available. We didn’t sample them on this occasion but the bars look well kept. Indeed, the club looks very well kept in general and well situated for music reproduction.
The car park will be locked overnight and Norma said she is willing to come in on Sunday morning to open the room to enable us to remove equipment left overnight. A very kind thing to do methinks. For those staying overnight in motorhomes there is limited space just outside the gates. For those wishing to leave their vehicles overnight the car park is monitored with CCTV hence those with motorhomes being asked to park off site as any movements may trigger alarms. Please keep your eyes peeled here for further updates.

That's a big space! Plenty of room for dancing

Better pack my Cuban heals.

So..........

I will be bringing a file based system built around:

Okto DAC8 stereo DAC/Streamer
Schiit Freya+ Pre Amp
Event Opal Active speakers

I will also bring an LDA MCA3 Hybrid valve phono stage.

[Halfway Tree]

I'll be bringing the LX521s as mentioned before together with a small fanless PC, 8 channel Okto DAC and Apollon Audio NCore 8 channel amp. I'll also bring the analogue x-over for the LX521s so a 2 channel DAC w/vol control, pre-amp, phono/TT etc can be run through the system.

As Steve mentioned the room is big, but should be OK hopefully. We'll just have to sit closer to the speakers if necessary. I didn't measure it accurately, but it's approx 10m by 15m. Steve's picture is looking across the 10m width.

The car park is right next to the function room so loading/unloading should be straightforward.

Looking forward to seeing everyone!

we can pretend we're American audiophiles with their massive rooms.

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.

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!
