A 3D printer?

I hadn't thought of that. I was watching a scary TV program where they demonstrated they could make a gun that could only shoot one bullet - but could not be detected... another peaceful invention used for evil intent.

But making a Waveguide, I would like to see that.

Cheers, Joe

Hi.

Does anyone have a opinion about using Baltic birch instead of MDF. The reason I ask is that weight is a concern for me. I've used MDF in the past but my back doesn't allow me to deal with the weight any longer.

I think it comes down to how thick you make the walls. I used double layer, 12mm Baltic Birch and the cabinets are still quite heavy. If I recall, each of the finished speakers is around 96lbs.

That said, you should be able to readjust the internal volumes and use 18mm Baltic birch. That should provide some weight savings.

If you are worrying about handling the raw material, I had the saw mill rough cut the pieces to a more manageable size for handling and transport, I just performed the finishing cuts. As for manipulating the cabinet as you progress, well, not much can be done there beyond enlisting the help of a buddy or a decent hand truck.

You are correct. The weight difference between BB and Mdf is only about 25lbs, for 32 sq feet. Not much of a difference really. Looks like a buddy is required for this job. Let me tell ya getting old Sucks!

Hi.
I am new to the forum but getting increasingly interested.
Do you still have these guides?

Sorry, I was away from my computer for a few days. Yes I still have the wave guides, The Elsinores are very good speakers, not quite efficient enough for an 8 watt 300B amp but if you have 30 watts or more it would be hard to beat for the price. Email me your address and I will try and get a shipping price.

I would agree with that. I had a 6 Watt amplifier and it was surprising the volume level it could achieve, but then if you advanced the volume control just a bit further... yes, I need a little more headroom.

But somebody listening to small scale jazz? Who knows?

Cheers, Joe
