I can honestly say, as far as I am aware off, anyone who has built them, no-one has regretted it. I agree that there is always a bit of faith involved before one embarks on what is a considerable project, so the assurance of others who have taken the road, is invaluable.

But, and I want to say this with some fervour, not everything is related to money (I heard a quote that it was the "American Decease") and success is as much to do with accomplishment and satisfaction. Real success is also measured in the eyes of others and on the basis of what you contribute, and not by the size of your pay packet.

Thanks for input as buying 4 boxes from PE might be more expensive anyway plus I love sawdust in the morning.
I can get free plywood from work as we have 1" high density plywood used for concrete forms. Many odd pieces get thrown out and recyling is a good thing. Would plywood be acceptable?

Is the crossover for the current drivers on Joe's website or buried in this thread?
I am about to place Madisound order.

Thanks
Ralph

Others have used good grade plywood and the results have been more than acceptable.

Re the crossover, not at all buried but is about two-thirds down the first page (that has links to other pages), right here:

customanalogue.com/elsinore/elsinore_index.htm

Construction Drawings:

customanalogue.com/elsinore/elsinore_4.htm

Internal Wiring and Damping:

customanalogue.com/elsinore/elsinore_5.htm

Useful construction photos - note some relate to Mark 1, but still are useful IMO:

customanalogue.com/elsinore/elsinore_6.htm

IF you are interested in the inner theory of the crossover:

customanalogue.com/elsinore/elsinore_17.htm

Why is that Tweeter in THAT phase? Read the article "Renegade Tweeter Theory":

customanalogue.com/elsinore/elsinore_19.htm

Finally, the FAQ page:

customanalogue.com/elsinore/elsinore_11.htm

From a constructor's point of view, those are the highlights.

Are there different drawings for the tweeter waveguide as they apply to the HDS tweet or do the original drwings still get used?

Looks like you start with several layers of mdf and then make waveguide from built up felt, do you use autobody filler or something similar to make a smoothed waveguide surface first?

The current box construction drawings are definitely Mk3 (using HDS tweeter).

Some of the photos show Mk1 and Mk2. As it says clearly "The Photos below relate to older Mark 1 and Mark 2 versions".

Ignore the four-sided waveguide shown in these photos and use the Felt pieces instead, as shown at the bottom of customanalogue.com/elsinore/elsinore_4.htm.

The two Felt pieces simply sits inside the cavity that the tweeter is mounted - the tweeter needs to be flush mounted inside that acivity, so that the inner Felt piece fits flat, as shown at the bottom of customanalogue.com/elsinore/elsinore_index.htm.

OK don't mean to be thick, just ordered my drivers and will start cabs soon.

I copied the attached picture from a completed elsinore someone posted.

Is this the setup for the HDS tweet ?

Would it be better to have smooth transition rather than a couple of steps ? Would be easy to smooth out.

Yes, that is it. The felt used as shown in that pic came from me, to Rob (rob323 is Rob a Mazda guy?). Others who have done their own and could not get the same thickness of felt - around 8-9mm (although the manufacturer says it's supposed to be 6.3mm or somesuch). They have used three layers, even seen a four layer. But as you say, if it smooths it out a bit it will not likely be a problem. But avoid making the cutouts in the felt round, keep them square as show, just more layers with cutouts spread out. I don't think that will cause anything adverse. BTW, round cutouts tend to show up at the same frequency, square spreads it out, generally speaking.

Good news, sounds like you are on your way. Go for it!

Just a quick question before I start making sawdust.
Could the lower 2 woofers be changed to the Peerless Nomex 8" woofers to offer a little more extension and ultimate bass capability?
The extra cost is fairly small

I realize the box will need to be larger maybe just extend the front to back dimension?
