Eton 11.2
I have a large used pair of bookshelves in the garage and am thinking about the Eton 11.2 kit, which will be a near perfect fit.
No one has suggested this kit to the original poster. Is it the cost verses performance? Is it not a good kit?
I would like to know but please do not let your replies steal this thread.

That are great driver aluminum cone drivers, like I mentioned earlier I made a carbon cone system that was flat down to 26Hz and very low distorsion. Did not sound as impressive as mine simple paper-cone flat to 35Hz that sound more full and dynamic, even with good specs. Paper simple good.
The Eton 11.2 is a well made kit. I like Eton woofers and have used the 7-380 before. The reason I did not suggest it was that gforse wanted a speaker with 2 10" woofer per channel.
I like the Dayton 10" RSS woofers. They'll go very low in pairs. Problem with them is probably at their high end because the cones are plastic. Alternative, a couple of pairs of used AR2 series or AR5 woofers.
They really kill you on price in Europe. For the Dayton 10" RSS in Europe $182. In hte US;
Dayton Audio RSS265HF-4 10" Reference HF Subwoofer 4 Ohm
It's often on sale for just around $100. If you are going to use 2 per enclosure, I'd go for the 8 ohm version and wire them in parallel.

Hello, I've been lurking for some time, but I think this is my first posting. I know this is a forum about DIY, but why not start with a good pair of AR9s, or 90s? Then, play with the crossovers, or maybe tweeters... at least then you'd have excellent base, and very good cabinet to work from.
...just a thought.

Plastic (polypropylene) cones aren't any worse than any other type of cone material.
Take a look at this pdf, at the frequency response graph. The cone is made from paper!
Anyway, what ever happens way up there should not matter, because in a three way setup you'd be crossing them well below the problem area.
Well as long as suggestions for commercial kits are being thrown around 🙂, here's my contribution!:
World Designs WD25A - a 2-way with a SEAS 1" soft-dome tweeter paired with a SEAS 10" woofer operating in an aperiodic enclosure*
This is a modernised version of the classic Dynaco A-25 (<---- excellent site btw), one of the best selling speaker systems ever, here in the States anyway. Actually, IIRC it was built in Denmark and shipped over here.
* they also sell a floorstanding version with more bass output

You're really pushing it with a 10 incher in a two way. Very narrow sweet spot in the upper midrange. Beaming overboard.
For 1000 € the dynaudio two way is a real bargain !!
Was the woofer used in the dynaco 25 the famous Seas which don't need any lowpass coil ?
Maybe those are two extreme cases where a midrange is not required ,or the purpose of the speaker is to give exactly the definition of a 10"+1" tweeter.
May the 100 mm voice coil give a real warmth to the sound 😕
😡 Those dynaudio are strange beasts ,have to borrow some ..😱😀

IIRC, yes. The woofer's roll-off was fast enough and smooth enough - for the A-25's price range - that it was decided no filter of any kind was needed.For 1000 € the dynaudio two way is a real bargain !!

Other such systems were sold like that back then, but usually by companies who 1) sold to the mid-fi market where price was definitely a factor but especially 2) built their own drivers, so the drivers used in such a system could be designed from the beginning to minimize the problems associated with that category of crossover system.
The 2-way 10" Genesis 110 is an example of that; also the classic 3-way JBL Century L100 which used a 12" woofer. BTW besides the L-pads, the entire crossover for the other two drivers consisted of just two capacitors.

Wow Guys thanks for the info!😀 I learned a lot! a saw great ideas
De dayton RSS serie's are nice subwoofer. however i can not order al the rss serie woofers. only the RSS265HF-4 RSS265HF-4 - Dayton High Fidelity Subwoofer 10 inch - Europe Audio if i order in the usa i would pay a lot of shipping and tax
however, i still have to design the XO from scratch if i use separate drivers. so what to do? I still haven't found a project that fits me. ( there are many idea's)
i like a system of a PR and driver. it roll up deep and you have no port noise and its cheaper that 4 drivers. so any ideas are welcome.
what about this combi Seas CA26RFX with pr H1305-08 - Seas CA26RFX 10 inch woofer - Europe Audio
so the question still remains what drivers with what cabinet 😉😕😱

1. A 10" with a PR is not the same as 2 10" in a sealed box. The later will (all things remaining equal) give you better transient response and cleaner bass. PR systems are primarily bass systems but with a sealed 10" you can go as high as 300hz (which means cheaper XO components if you are going passive) which means you can use a smaller mid (which will give better dispersion for the upper mids).
2. A PR is in most respects equal to a port. You avoid the port noise but loose some transient response as the PR's mass has intertia.
If you are looking a 2 way + subwoofer (the Dayton you have specified above is a subwoofer) then please consider the SEAS L26ROY or Peerless XXLS instead. SEAS sells a matched PR for the L26. I dont know about Peerless.
So are you looking at building a 2 way + subwoofer or a 3 way? Your driver choice will not be the same.
Sure you can push a 10" to 2000hz. There are many large "fullrange" drivers that exceed 10" diameter but I dont think this is a design gforse is looking at.
If you use an appropriately sized (large) port, there should be no noise.
A Passive Radiator is only a port substitute. If you want to get better performance from a bass reflex system using a passive radiator, then use a passive radiator that is one size larger than the woofer. So for a 10 inch woofer, use a 12 inch passive radiator.

You totally missed my point. I wasn't referring to frequency response, I was referring to power response, dispersion.
You get an abrupt change in the polar response when the spectrum shifts between a 10 inch woofer and a 1 inch tweeter, especially when you crossover that high.
Oops my bad. Sorry. How do the large coaxial drivers like the Tannoy Concentric Dual, Beyma, Radian, 18 Sound, Ciare NDCX or Hawthone Audio Iris manage to compensate for this change in the polar response? Do they manage the crossover and crossover really low (around 1000Hz or lower?).
I know you know the answer...Navin 🙂
Correct polar dispersion pattern (just joined the Guru Terminology
)
is achieved with the use of the waveguide ,and mouth area and curvature geometry determines how . There must be some tricky trick also in the crossover ,like a little bump in the crossover region for both speakers , then the summed outputs would be projected ahead , depending also from baffle dimensions .
