The "Elsinore Project" Thread

[CCU]

i'm am definitely going to build these speakers.
but what did you think about moving the bass unit for the center speaker? to many unknowns that could go wrong?

because i think i am going to try it, if it sounds terribel i might have a few options for getting it messured

but my girlfriend disided she also wanted to have some influence on how the speaker ended up looking.
She came up with the idea of making the sides curved and i also quite like the idea(but not the ekstra work!) i showed her the german built speaker, those are beauties

I would make the frontbaffle and the internal volume the same. that should not be a problem since i dabble in the dark arts of math
the reason i ask is because i seem to remember reading on your website, that the resonans of the cabinet could change the sound.

Joel's mini review continues, he seems to have sorted out better what the Peerless HDS tweeters are doing:

Part 3:

Just wanted to let you know that I've been listening all week and thinking about the treble. I'm going over everything that I can think of and believe what I'm hearing is simply the tweeter's ability to reveal how the treble was recorded. Since every recording is unique some don't have as much cymbal ring coming through from the recording process but when the recording has the treble content then it shows. It's not a case of one recordings having less or more treble it's the amount of treble complexity in the recording coming through. The scanspeak tweeters in my other speakers have their own personality so the treble differences within the recording are not displayed as widely I've always found the sound of treble to be the hardest to figure out but I thing I gradually discovering that the Peerless is an amazing tweeter...

Dissecting the Elsinore means nothing anyway because they simply sound Fabulous but I will post much more thoughts and experiences on diy audio. I have a personal vendetta against some commercial brands and mainstream magazines based on some bad experiences, so my retaliation is to try to get people to believe/realize that the Elsinore easily competes with Big name brands that are very expensive. It will better many of them. Last night my friend said these were better then the Wilsons we (myself and my friend were on a road trip) heard in Chicago - I thought the same thing earlier in the week an had not mentioned that to him... I much prefer them over Sophia as well for different reasons. The Wilson we heard were the Maxx series 2...

I going to experiment much more with many many recordings along with listening to them up stairs in a wide space without treatments. Hope to have 300b mono's running soon as well.... I'll post thoughts on Diy audio.

Later, Joel.

Joe, I sent you an email last week, had a chance to digest it yet?

OK, I understand what you have in mind. I don't really think it will sound terrible, but it does come down to diffraction loss being a bit different as there will be bit more effective baffle area. Let me put it this way, use the current crossover and then listen to them. After that I can make suggestion which component (as it will most likely be only one - but not promising that) that you can change its value in a certain direction and then listen to it. Also being able to do a pink noise test (also called RTA test) could be useful. You will need a burnt CD disk with pink noise recorded on it (I could post it), play it and then use some mic and software to capture it. We can look at those details a bit further down the line.

Hi Joe,

I have'nt yet build the elsinore but I am using the hds tweeter and hds woofers in my 2-1/2 way DIY speaker that I'm now using for HT. I did also noticed the sound of the hds tweeter is not quite natural and detailed compaired to some Seas and other commercial high end tweeters I'm also using, I think the hds is fine from 2K to 7Khz but above that, I think the sound have a hint of dirtiness and lack of transparency.

I am thinking of building the elsinore but with another tweeter, But I cant find another tweeter that have the same sensitivity and have similar characteristics of the HDS tweets.

Though the HDS tweets is a very good tweeter, I dont think I want to use it in my next project.

Are you surgesting making the center a bit more narrow to reduce the baffle area?

But i'll start of with the standart crossover and i thank you so much for wanting to help with tuning the center crossover

i'll get started as soon as the plywood i ordered is delivered. it's not easy getting a hold of 3mm plywood in Denmark(at a reasonable price)

What would you like me to say?

Hi Joe,

Sorry for my post was kinda vague.

I was hoping that you could suggest an alternative tweeter for the mark3 that could take the job of the hds tweets with same ease but sound lighter and airier on the top octave, but with a price that is not very expensive.

Thank you.

The upper driver in the current design sees less baffle area than the bottom. Your arrangement now increases the baffle area for that driver - the other(s) are not affected. For now don't worry about it and definitely do NOT change other dimensions, especially the narrowness, as that just complicates matters more.

3mm plywood? Is that right?

okay then i won't change the baffle

As i said ealier on my girlfriend doesn't think the square design is pretty. therefore i'm making a curved cabinet, internel volume, "windowarea" inside the case og baffle kept the same.

i chose the 3mm plywood because its bendable, i'm going 2 make both sides and back in one piece of ply (kinda like B&W's 800D) and the same shape as the B&W 804S
7 layers of plywood for the sides, it is NOT going to be a fast build!
also building one of the standart elsinore kanibets for comparison

i'm also making an eksternel crossover box and thinking about using 2 bassreflekstubes,
one at the back and one in the bottom, then closing one of the tubes,
maybe this could make it easier finding a sutible placement of the speaker. but this is stil only a theory.

Edit-
this is for all who has build the elsinore speaker, which cable have you used for the internal wiring
i am thinking about using QED Silver Anniversary and i am going to be eksperimenting with 3x2.5mm2 solidcore housewiring cable for the basspeakers
