ALUMINUM WAVEGUIDE

Have to take back for recessed screw holes. should be fine for machine screws as well. wood type screw for plywood is good but not so good for MDF

Default waveguide

Hello Joel, I posed a similar suggestion to Joe on this same dilemma, the back portion to match the tweeter flange contour. It was to think of the tweeter flange as an inclusive part of the waveguide and not something that mounts to the guide. In this respect one could first machine the back face that would accept the tweeter in the same fashion the tweeter accepts the (original Peerless) flange, and by doing so the plate (aluminum) can be flipped back over to machine the mouth, throat and flare at the exit. This I think will eliminate the additional attention to the tweeter/flange matching the guide. In essense the tweeter (without flange) would mount directly to the waveguide!
I could include a drawing if you do not see the image in your head!

Hello again Joel, I was a little to anxious to reply to this post as the images were slow to come online! It appears you have the fix already. Good work. With that said I would like to be on the list to order a pair! Sorry for the mix-up!

Hi Guys

With some help from Spoonted, this is the latest crossover. With certain source material with consistent bass below 100 Hertz R2 can get quite hot. So it should be a minimum rating of 10 Watt.

AMENDED CROSSOVER:

I would need a pair of the boxes here fitted with the drivers - then add Waveguide and then do a significant amount of work - the drivers are measured in situ, both electrical acoustic measurement, all which are imported into computer modelling where the initial crossover can be developed. Then the crossover needs to be physically constructed and tested and additional changes needed from there. Naturally we are talking about listening and then matching the tonal balance of the Elsinores.

We could call the Hamlet Mk5 so that it is apparent it matched Mk5 Elsinores.

So... needs to see the boses... ?

Cheers, Joe

A number of people have fitted the crossovers to the bottom of the box. While I prefer external because it makes it easier to work and tweak them, doing it internally is OK by me. Some may point out that external crossovers see less vibrations, that is true, but I wouldn't make a big issue out of it.

Cheers, Joe

It will take some time but I'd like to see the first pair finished. Nice paint coat. Fitted in filler board
At this point I could take the orders and have them made and painted all together

Unfortunatley the weight of AL is more than I guessed. The total will be more like 2 or 3 KG

Planning a Hamlet build for center so extra Waveguide is needed. Hopefully the new xover will come out.

Hi Joel, can you paint aluminium? I thought aluminium is anodised.
