Hi,
I was wondering what you would recommend for someone that is looking for a home cinema speaker with a good directivity (smooth directivity behavior without any sudden changes)?
It should be in the price range of 350 Euros per speaker. The woofer should not be more than 8".
Greetings

Look at the smaller Revels as an example. Or some of the smaller powered speakers like the JBL 308 Mk 2 as another example of a design that has a smooth transition between drivers.

If building I would have a look at the Speaker Design Works Statement series -
Statement mini (TMWW tower) for fronts
Statement monitor (TMW) for rear and
Statement centre for .......centre
All based around the Dayton RS180, Tang Band w4-1337 and Fountek Neo CD3.0 ribbon - so all pretty middle of the road drivers pricewise but all get good reviews and fully published plans to work from. This will push your 5x$350 budget though but may be worth it.
Or cheaper is the Tritrix series that are planned for floor (TL) and stand speakers and being an MTM 2 way can also be used as a centre. These use Dayton DA130BS-4 and DC28FS and have very simple crossovers so should be very cheap to build. Parts Express have knock down or component kits from $150-300 per pair - well within budget but may be a good place to start.
tritrix - Parts Express Ships Fast and Ships Free.

Just a couple of thoughts to get the creative juices flowing.

Hello,
definetly build, thx Rob for the JBL suggestion though.
Thx Ugg for the statement suggestion, that seems right up my ally, but I can't seem to find meassurements of the directivity behavior.
Btw: The directivity is more important than the budget. So if something more expensive will meet that criteria, feel free to suggest it 🙂

That is a good suggestion, but I am looking for an already buildt version. A geddes clone clone so to speak 🙂
Yes, based on viewing distance, so recommend researching whichever THX performance class speaker systems best meets your needs and either buy or use as a guide to DIY: THX CERTIFIED LOUDSPEAKERS - THX

Take a look at the ER18MTM Ribbon design by Dennis Murphy from Meniscus Audio.
ER18MTM Ribbon (Pair) - Meniscus Audio
Ribbon tweeter is probably your best bet for getting the horizontal dispersion for HT that you want.
Right in your budget spot for a pair.
There is also a matching MTM Center using the same drivers.
Dennis Murphy is a top designer. Can't get much better than his work.
Use 5 pieces of Kef Q350.
Measurements available in Stereophile. You get smooth directivity on both axis, concentric speaker for about 560€/pair.

Thank you, I will take a look at them.
What makes me sceptical about the Q350: Shouldn't the hard edges of the enclosure create a pretty dominant baffle step?

Hard, beveled or rounded edges of the cabinet, you can not escape from baffle step effect. Diffraction at high frequencies, on the other hand, could be the problem - but since it is waveguide loaded tweeter, it does not interact that much with edges as regular tweeters on the flat baffle. That's why it measures relatively well at Stereophile.
As for baffle step, it is fairly well treated as can be seen from the measurements:

In an earlier post you said that you were definitely going to build. I would stick with that if you want to get the most performance for your money. The sound quality difference for the same amount of money can be dramatic.
Based on the good reviews here, I bought myself a set of Behringer B2030As. Cost was a whopping $139 each.
I bought them for my office, but wound up moving them to my TV room because they look so much better than my DIY speakers.
Here's the polar response of the Behringers at 0, 11, 22, 33, and 44 degrees. Above 1200Hz the beamwidth is more than 90 degrees. It's hard to say exactly how wide, because I only did measurements to 88 degrees. I'd estimate about 120 degrees.
Here's the Kali Audio LP6. While the Behringer is a clone, a copy of a Genelec monitor for years ago, the LP6 is a new design from Charles Sprinkle, formerly of JBL and designer of the M2 waveguide.
I haven't listened to it much yet; it just came today. In a cursory listen, it sounds more "neutral" than the Behringer. In particular, the tweeter on the Behringer is a little bright and the LP6 sounds more "laid back." The build quality of the Behringer is significantly more impressive. The Behringer is heavier, looks more expensive. The LP6 is surprisingly large, about as large as you would expect from an 8" speaker. (It's a 6" speaker.)
Here's the polar response of the Kali Audio LP6. I've built a lot of waveguides and I would generally expect an elliptical waveguide like the LP6 to outperform a round waveguide like the B2030A. But this one's a real toss up. The beamwidth of the LP6 is more consistent than the Behringer, but the LP6 has a noticeable dip on-axis at 2700Hz. Cross firing these speakers might be optimum.
The smaller tweeter of the Behringer allows it to maintain pattern control all the way to 20khz. The large one inch tweeter of the LP6 begins to beam dramatically at 13.5khz (one inch.)[/QUOTE]

I was going to build some, but I instead decided to buy JBL Studio 530s as they were clearing them out for less than it would take to buy comparable drivers, not to mention the cost and time to construct the cabinets. I needed a horizontal center channel and was unsure how to construct one that could match the rest of the speakers and sound decent. They sound good in my 5.0 system. Soon I will add some subs.
That's been something that's discouraged me too. For instance, if you look at the performance of the Behringer that I posted, it's spectacular. I've been half-tempted to swap my Cosynes out for the Behringers and see if the difference in quality is night and day.
The Cosynes sound REALLY great in my room, probably as good as anything I've ever owned. But at the same time, when I had the Behringers in my room, I never invested much effort in getting them "dialed in" like I did with the Cosynes. With the Cosynes, I added a MiniDSP to the mix and used a mic to get them to measure well at the listening seat. With the Behringers, I didn't do any of that.
Basically, the quality of cheap speakers is ridiculous these days. For comparison's sake, eighteen years ago I had a set of DIY MTMs and a set of JBL HLS 810s. The JBLs cost about $600, and my DIY speakers cost about $200. My DIY speakers were noticeably better than the JBLs. In particular, the JBL used a cheap mylar tweeter, and my DIY speakers had a nice silk dome.
Fast forward to 2019, and there are speakers that sell for $200 that would have legitimately cost $1000 ten or twenty years ago. I'd say that the build quality of the Behringer is about as good as what you see from some DIY designs that cost $500. They're $129, with free delivery.

If you want consistent, wide dispersion, you might take note of the impact that an anti-diffraction PVC frame made to the dispersion pattern of an inexpensive commercial bookshelf speaker using a cone mid-woofer and dome tweeters.
