Yes, that exact enclosure.
I bought those enclosures from a local old timer who had made them with alot of care. they are heavy! They had a single goodmans driver where you see the Scanspeak now. I swaped it out and installed the Scanspeak and tried different drivers on top. This was before Dannoy and my introduction to THE Scanspeak.
When your Dannoy discovery hit I cut a hole right in the front of the enclosure and bolted the 10" Tannoy in and listened to a LOT of music for days after that. With RI, it was mind blowing. Something very different.
I then pulled the 10s out and glued in 15s. 
The 15 can handle a LOT of amplifier power so that helps in overcoming the limitations of the 10 but it does not sound as good as the 10 in the mid range. Its just not as fast, not as refined and nuanced but still excellent, don't get me wrong.
It's not so much there is any problem, or there is something I don't like, I like it a lot! it's more its a 2 channel system so its never going to be big enough for a main system. Dannoy does have that romantic sound to it but less than a straight up Tannoy. If I were to tire of anything, it would be that but as i'm not relying on this being a primary system, i dont find it a problem.
I am highly satisfied with Dannoy and the lineriazation effect I hear with that configuration. I dont desire more from Dannoy as I'll use it for accoustical spaces that are small and it's a good match for. If i need more than that, well, back to sealed enclosures. 


Now, in saying all that, from what I picked apart this week re Dannoy i do feel that we might be able to decouple the linearization effect from Dannoy, for use in other systems. particularly with higher efficiency drivers that tend to have more cone resonances, It could be very beneficial.

Not potentially a mess
Definitely a mess.   One I would walk away from...
Re RI, you STRICTLY only want to implement rears or the game is off but if you want to talk RI, lets do it in the RI thread.
Re the 10" being too little, think back to the port analogy. What would convention say then about the diameter required for a conventional port? Remembering this 'port' is far more controlled than the mass of air in a conventional port...

Exactly

I think the issue is system power levels not F3. I think The efforts for implementing something under Dannoy is more toeards improving that not so much lowering f3.
Dannoys open bottom end sounds really good. I'd be keen to preserve that but somehow being able to go 3 channels.

Exactly that's the point! More power below some 60Hz not lower f3.

Thanks Edgar for the 15" vs 10" comparison. Btw how big is the space that you use with your Dannoys and how far are you from the speakers?

@ Paul _ I have not tried high passing Dannoys but I feel the feeling will be similar to castration. It is the bass where the magic comes from.

Cheers,

Conflation
F3 was not cited as a pivot for improvements, it's just a flag. I'm saying the Tannoy is not the only vintage 10" driver that will not actually do LF, regardless of FS, and a proven way to make the most of these drivers is to +/- relieve them of LF duties. Hell, I currently do the same with my own (very modern) 10" MF. I mean, if you like 10" bass, why NOT try doubled Scanspeaks under high-passed, stand-alone Tannoys before trying something more elaborate and costly? And it might be you would lose no more "LF" by high passing than you do now with the PR. You will never wind up with a power house, but you will very likely gain significant headroom. It's so straightforward and easy (also easily reversable...), I can't believe you have not already tried this...

Yep, it is unexpectedly and ridiculously good, have no idea right.
Edgar, I know exactly how you feel. I had once a 15-in driver but I had no use from it. Heard in the multiple installations 15 red, included autograph, but always was destructed bite overly romantic and syrupy presentation. This is why I choose 10 red, because I use it for many years injecting very deliberate amount of syrupiness into Macondo. I actually do not have memory why I suddenly decided towards 10 inch red to the sunspeak.  But I very clearly remember exactly how you described that it for whatever reason took a lot of bed euphoric red driver sound away, and kept only vote in my view should be staying there. As I discovered it it was laughable and shocking and it really turned my head off. I hand my entire systems hitting in the room and I have two dirty and shity boxes with two 10-in holes, driven from B2 and connected with zip wires, and they sounded amazing. I still remember the recordings I played and I exactly remember how they sound. I need to admit the guild. Before I released all of this public I called to a friend of mine who manufactures speakers and I told him about discovery. He did not believe me that it might be good. So, I said fuck you then and printed it publicly. I do not know if your explanation why they sound good is correct. However I feel that the people who manufacture right now speakers using vintage Tannoy drivers should certainly make this experiment and then express their "alid" opinions. I need to admit that if somebody suggests to do it for me I would probably discard the suggest as well but it is what it is.

You are right Paul
I have tried it Paul, and more. None of them are as good as Dannoy.
I can see it now, It's the linearization effect the Faraday rings have on the system. That is what other systems do not have. It's like adding a choke to a amplifiers power supply. It's a magnetetic phenomenon. It doesnt really dampene the energy, its spreads it out. It takes the high q system resonances and flattens them out. hence the term linearization.

My accoustic space
is about 60m3 or 2000ft3
but with openings to other spaces.
It will never be an ideal acoustic space here so I have not put any significant effort into room treatment. except for RI of course hehe, that is some good room treatment.
The action is defiantly nearfeild but in saying that I have a couch by a window in one of the adjoining spaces and the lower knee loads into that corner better than anywhere. It's a devine place to snooze and soak up some sun.

It is ridiculous
Friend after friend leaves astonished saying how "dialled" the sound is and the system was literally slapped together via the path of least resistance just for proof of concept. Development ended there other than adding 2 more braces to the speaker enclosure. The proof is in the fact that it ended there. If i was not satisfied the configuration would have changed by now or been stripped down and replaced with something else. The irony.

Agree that shorting rings, etc. can be useful; my own dynamic drivers (LF and MF) employ them to good effect. One supposes the overall effects of the SS "PR" with your 15" would be less than Jarek's (10+10), and that you would in any case start with more LF and more drive. Jarek has said specifically that he wants more LF and drive for symphonic music, and this prompted my "recommendations", using a least approach.  Romy did a great job of describing both the benefits and the weaknesses of the Dunnoys, and I tried to consider these descriptions, also my own experience. Sure, it's always a matter of taste and satisfaction; we all like what's good.

Best regards
