Is the Dayton H6512 the copy of this, Patrick?

that's right
In the past, it has been challenging for me to get midranges to work on existing waveguides. Basically, most glues don't stick to ABS very well. This is complicated by the fact that the surface of waveguides are curved, so you're trying to get something flat to laminate to something that's curved. It's tricky.
I once tried to "unitize" the QSC waveguides used in the Econowave Deluxe, and I gave up because the 3D printed mounting plates peeled right off. Bolting them to the waveguide certainly helped, but I wasn't keen on the idea that the glue might be delaminated while the bolts are holding the midrange mounting plate, leading to a leak between the waveguide and the plate. So I shelved it.
With that in mind, I wouldn't rule out the possibility that I might just create an entirely new waveguide for the 520C, and just keep the enclosure alone.
My woodworking skills are abysmal, and at a price of $135 for the entire speaker (delivered), that's not much more money than a flat pack would cost.
As illustrated in the attached pic, the entire face of the speaker is a single piece of plastic.

Something that I've been harping on for about ten years now, is that the quality of REALLY cheap loudspeakers is ridiculously good these days. Although I own a set of Waslo Cosynes, they've been relegated to a spare bedroom due to WAF. In their place are Behringer B230Ps, which I paid something like $150 each for.
They're shockingly good. I bought them because they beat the Linkwitz Orion on a blind listening test here on diyaudio. (And, oddly enough, a speaker inspired by the Bose 901(!) beat 'em both.)
In that same vein, it's clear that the $125 Studio 530 shares some DNA with the Synthesis Array 1400 BG, which costs 50x as much:

I found that a 3D printed adapter that matches the curve of the waveguide plus PL Premium adhesive sticks like crazy to ABS surfaces. I did that with the point source bookshelf horn.

Here’s the adapter:
That compound curve was crazy to make. I don’t even remember how I did it. We did not have 3D scanners on our iPhones back then LOL!
I traced paper cutouts and digitized them and then spline fit them on SW I think.

Yes, this speaker here:
XO was DSP Harsch at 600Hz:
I originally used a pair of Dayton classic 8in paper cone woofers but eventually moved up to Dayton RS180P-8 7in woofers and a SB65WBAC 2.5in full range at the throat.
Here was measured polars:

There’s another sale on the Studio 530’s direct from Harman for $239. That’s a very good price on a great sounding speaker. You can decide if you want to Synergize it later.

I bought a pair. What sized resistor did you use to pad the tweeter? They are just slightly bright in my live room.
I used a 4.7ohm 10w between the woofer and tweeter binding posts. Remove the included jumper and replace with resistor.
- I am more amazed every day by this little speaker. The JBL-530 is only 86db , but I needed to break in my new - little 2 watt SE84UFO Decware Tube amplifier with 25th Anniversary mods that I finally picked up recently but I have a low inventory of speakers at the moment - ( sold several sets of my speakers ) - and I needed to break in the JBL-530's - so I hooked the little tube amp up to break them both in at the same time.
- At first things were not sounding very good the combo was pretty harsh,, not much Bass , and things got very muddled with complex music passages, but I have about 60 or 70 hours on both now and those 2 watts actually can now rock that JBL-530 Speaker!!! As time went on they got better and around 50 hours I noticed Big differences!!!
- So then I stated playing my most dynamic music I have and turned up the the little SE84UFO as high as I could without too much distortion and those little woofers got even better and now I can play - Bela Fleck & The Flecktones - "Flight Of The Cosmic Hippo" - which has some very demanding Low Notes and they can actually play most of those notes! I don't know which impresses me more the amp or speakers! , ( well I do but still I'm very impressed the speakers considering they use a very small 4 inch woofer! )
- I can't wait to build some kind Woofer Base for the speaker and relieve that little woofer of some of the it's bass duties!!!
-- Sorry for the thread hijack but , I knew that the little Decware SE84UFO Amplifier was good from all of the press over the years and especially from the round of Excellent reviews it got this year , but this is by far the best amplifier I have ever had in my system!! - As much as I really Loved my VTL MB300 Deluxe 300 watt Monoblock Amplifiers - and they were Very Good , this little Decware Amplifier is in many ways Much Better than those six or seven thousand dollar Monoblock Amplifiers were!!!!!
- The SE84UFO with the 25th Anniversary mods is one of the Best Amplifiers I have EVER Heard!!!! , They are So Musical and I am hearing so Many things in my recordings that I have never heard before!! And I am really excited about building some 95db+ Speakers to really see what this Amplifier can do - !!!!!
If you have never heard one of the new Decware SE84UFO Amplifiers you Really owe it to yourself to hear one!

Glad you found breaking-in useful. The suspension must have loosened up. JBL says they are 5in woofers but they do look closer to 4in. I am not sure I would ever find 2W enough. Although my latest speaker only needs 2W to rock the house as they are 91dB sensitive. I am driving them with my 100W TPA3255 Class D amp.
I am working with JPS64 on a new 350W push pull monoblock tube amp. 🙂

I want to have several high efficiency speakers for during the summer months here, I'm looking at several different ideas right now... Probably starting with the Lii Audio F15 Driver in a diy Caintuck style Open Baffle, along with an Open Baffle Woofer set up.
- Then maybe a speaker based on the Neo8 or Neo10 speaker drivers....
- I have your great TPA3255 Class-D Amplifier! , and I have the Starke Sound AD4.320 Class-D Amplifier - but I am looking for another Amplifier that is higher power too ,
- I need to eventually put my Purifi drivers into a design - 🙄 - LOL ......... I may try and sell my 2 pair ... I am thinking about maybe trying to build Troels Gravesen's Purifi Speaker - the big one the Purifi 6661 , Have you seen it? -- Unfortunately the design uses a different model Purifi driver than what we bought in our group buy, I think the original was 4ohm and he is using the newer 8ohm drivers...
- and then there is another speaker that I really want to build but it likes a lot of Power. - So very interested in the new 350 watt Amplifier you are designing - what will it be like for heat output - any kind of sliding bias or other tricks???

I'm not really an "amp guy." I know this is heresy but I've never owned a solid state amp which was obviously better or worse sounding than any other solid state amp. I've been running tripath amps for about 20 years now.
Having said that...
I used to power my Gedlee Summas with a headphone amp on occasion, and it sounded pretty good.
Power output was ridiculously low - something like 1/10th of a watt - but even at that level it was enough to get them to something like 80-85dB.

It's not heresy. You just haven't gotten into amps yet like you are into building horn speakers. I used to think the same thing, but you don't know what you don't know. It's like saying all mid bass drivers are the same etc. Good well designed amps sound similar, but there are differences with low distortion solid state Class AB amps with lots of feedback and higher distortion single ended Class A amps with zero feedback. Soundstage and imaging, smoothness of vocals, and foot tapping dynamics are very noticeable.
Try building a MoFo SE Class A amp - makes about 11W- enough for many of your horn speakers.

I used to think the same - until I had a chance to do a direct comparison between a Denon Mini receiver and also Denon PMA-1500AE on the same speakers in the same room. Nigth and day.
I wouldn't so much with a speaker the likes I presume that Patrick Bateman listens to.
Geldee Summas should be perfect for a 11w amp, no? Unless Patrick has sold those. Bit most of his designs are high sensitivity horn type speakers.
