    No, unfortunately not. The size of PVC that we needed for the Statements W4-1337's was 5" ID PVC which was only available special order at local home stores. I could have gotten it through a local plumbing company supplier at $100 for a 20 foot length. So, I decided building the mid tunnels out of MDF was an obvious choice given the cost difference.

    If I could have used PVC at a reasonable price I would have used it in a heart beat.

    Thanks for clarifying Jim. FYI, I've been drooling over your designs for a few years now hah!

    With regards to the Anthology's, I'd like to stick as close to what you and Curt intended with the mid tubes if I can. However, If I can't source the right size tubing, would building the tunnels from MDF like the Statements series work?

    Cheers

    The Anthology's are the design I recommend most to music lovers that have varied musical tastes and CD's that span several decades. Curt really nailed the crossover as usual and the driver selection just does everything well whether its home theater, Ozzy or Bach.

    The PVC mid tubes have a lot of fudge room. The PVC I have available locally is available as schedule 40 or 80. I picked the heavier wall variety but anything close will work fine. Sonotubes would work just fine too. The end goal is to create a tube that allows the mid back wave to exit the rear of the speaker and isolate the the bass compartment without impeding the back wave too much from the design. You can also compensate for different rooms etc. by simply varying the amount of foam you line the mid tunnel with. Its simply very flexible and easily tuned for different situations.

    The Anthologies by Jim and Curt are another option with open sb mids and dual RS225 woofer drivers. Paul Carmodys Sunflowers are another to look at, and they're a hybrid ported woofer/open baffle mtm that have been raved about. Have you checked out any open baffle/ H frame/ U frame setups? They're a different animal, but they have converted many more conventional speaker listeners over. They can throw a soundstage that is flat out incredible, but they have a need for space, and the bass is wholly different from the presentation of any boxed enclosure. Two 15's per side and some Steven Stills, and.........well....I'll not forget that anytime soon. Listening to a great rig with great OB's was as ear opening as the first time I ever listened to Klipschorns. Glenn.
    I have to agree with you on this, having recently heard Charlie Laub's nude system at the Meniscus/CSS get together in the fall of 2019. He had twin 15's in an open baffle set up with a 15" for the mid and a pair of opposed tweeters that was very dynamic and uncolored to my ears. Can't say much about the imaging but there are a lot of factors that affect that. I really liked that system.

    Cheers!
    According to the website http://speakerdesignworks.com/Anthology_3.html, the pipe required is 6 5/8" outside diameter and 6" inside; I think (think!) that the inside diameter is the critical one, the wall thickness is for strength: someone please correct me if I'm wrong.

    I would be surprised if you couldn't find 6" (15.2cm) internal diameter pipe somewhere, particularly from a plumbing supplies store, but 150mm is available from Bunnings, maybe that would be OK?

    Here's a build thread which might prove interesting: https://www.diyaudio.com/forums/mult...ogy-build.html

    Mr Holtz, the designer, is a frequent visitor to this Forum and would be able to advise you on this matter.

    Looks like Humble Homemade Hifi also have a kit coming out soon. Might be worth taking a look!

    I'm familiar with the Sunflowers but not any other OB's. Any recommendations?

    Statements II's coming in close second. Unfortunately Zaph's SB12.3 might be a bit too big for the room.

    Cheers!

    Indeed, my mistake. And look like even better value.

    Here's a link to the designers' listening impressions for the Statements: I have to say that if I had the budget and the room, I'd find these hard to resist.

    Driver cost might be within your $ limit.

    I own the Solstice system and love it, but there is no way it will keep up with the Statements in the bass department. It may reach as low, but doesn't have the displacement to pressurize the room. I was impressed by that capability of the Statements in a very large room where I heard them. Haven't heard most of the other designs you are considering.

    Well, you have some great options from which to choose! And you have a great budget.

    You can be assured that they will all sound good and have had many hours of work put into their development: but they will sound different to each other and to your ESS Monitors. From all accounts, the ESS were/are very highly regarded (and priced accordingly on the s/h market) but the mids are a bit lacking and the bass a little fuzzy.

    I think that whichever speaker discussed above you go for, those issues will not be a problem.

    To help you choose, maybe have a think about:

    how useful are the designers' notes and product reviews, how do they match your expectations and listening requirements?

    how will they look in the room? Will they be too heavy to move? If, as with Zaph's SB based speakers, they have to be placed a relatively long way from walls and corners, will that be an issue? It's great that he makes those recommendations, of course.

    will the cabinet be easy or hard to assemble and finish?

    how easy/hard will it be to assemble the crossovers (A: probably much the same, unless you do an MTM)

    are the drivers readily available?

    do you have enough amplifier power to drive them without any trouble?

    etc


    Please keep us informed and don't hesitate to ask questions and seek advice.

    Geoff
    Thanks Geoff,

    Yeah it's easy to get carried away with what they look like and you're right, they're all good designs and I probably won't go wrong. Just need to make the right choice for me.
