Yes, it is unusual, but the British are unusual. I can say that the P3's construction is first class using the best materials. I have never seen tighter miters.

I did not mean it to be harsh at all. He is concerned about crosstalk. Headphones are the best way to defeat it. 

I think building your own speakers is a wonderful thing to do. There are hundreds of excellent drivers available, your computer gives you the power to make important measurements and digital signal processing makes time alignment and phase accurate crossovers a breeze. I know exactly what I would do for dynamic speakers. Unfortunately, I am an ESL junky. All I have left to do is the subwoofers and they are the hardest enclosure to get right.  

I take it negatively guess why ?

In another post you claimed that headphones listeners are not true audiophiles because headphones are inferior to speakers...Do you remember ?😊

In my world , and i disliked headphones all my life , they are different not superior or inferior ...

Each one has his set of problems which must be adressed and these problems are as important and impeding S.Q. in the two cases. and NONE was inferior or superior precisely because of the negative impact of the trade-off implicated in these different designs ...

Crosstalk is the main problem of speakers with the room acoustic complex parameters to balance which problems are huge problems never adressed or even never perceived as problems ( especially crosstalk) by many audiophiles ...

Shell design and flawed acoustic chamber of the headphone and the absence of HRTF function transfer in the design of headphone, and the phantom image very artificial illusion centered in the head and the lack of body response to the dynamic pressure of the sound and the frequency constraints of the cells compared to a real instrument etc...

Neither speakers right out of the box neither headphones are superior to one another contrary to what you claimed associating headphones owners to secondary cheap audiophiles... ( the ratio S.Q. versus price indeed is superior with headphone)..

Then i take your sentence as a sarcasm at least and as a refusal to answer to my criticism of your post above with no arguments save insult...

You can now say what you said out of the context of your posts as if this sentence was not what it really was...i will stop here ...I dont want to inflame this discussion ... but truth matter ..

I have no grudge against you , i just give my opinion ...😊 And i entertain no grudges precisely because i always give my thoughts clearly here with arguments...

I have no idea at that roomy size. I have experience with smaller rooms and a lot of speakers but that's a big space to fill. You are right, they would be too small. My guess is you need to move a lot of air, maybe used horns at that price range? 

@mijostyn I misunderstood then.

To be fair, you could tell me I should stick to baking. (I think I can bake)

I have an infinitely small knowledge of all things audio yet I am still here and comment on things, when I feel I have something to contribute. But I am probably a moron 9 out of 10 times. There were no exam to pass to enter this forum :)

Room size concern: I am currently running my Nautilus 804 as SMALL speaker with lowest sub crossover my receiver can offer (50 Hz). Her two 16.5 cm low woofers cut at 350 Hz, and the large mid range runs from 350 to 4k.
