Unfortunately, I don't know what 'full spectrum that this unit can reproduce with attitude (and exceptional vocal reproduction etc. you name it)' means. They have no technical definition of any kind and are entirely subjective, thus will vary from person to person.
No thanks, I won't buy it just yet. I can't afford to purchase any drive units at the moment, nor do I require a 5in widebander, although no doubt I'll have a pair through here at some point. I'm very surprised that you are sorry it's built by Tang Band though. They produce some excellent drive units of their respective types, several of which, such as this model's poly-cone sister & the smaller flat-cone models, I was under the impression you rated very highly.
Eh? 😕 You'll no doubt think I'm dense, but I can't work out what you are talking about. Could you clarify? Are you calling me a liar? What am I supposed to have lied about? What 'crew'? I am not employed on a ship, although admittedly I am a naval historian. What am I supposed to have learned? From whom? Yourself? Somebody else? I would like to think I learn something every day, but without knowing what exactly you are talking about, it's somewhat difficult to know what you presumably want me to say.

There is no need to play such childish games with me, you (and the crew) have understood what I meant altough my English is not spectacular.
I wrote one post at the same time as you, go back to page 4 to see it. Thats all.
No hard feelings, we are just talking here 🙂 I wont spam this thread any further, if you need to talk/clarify my PM is open.

Ah, I think I see what you're driving it. I think (correct me if I'm wrong) you were / are calling me a liar for checking the information on the Tang Band data sheet (through WinISD Pro, Unibox and my own Excel spread sheet since there is usually a little variation in the calculation methods / how much simplifying of the maths is done between different pieces of software) and noting there are mild discrepancies between the different values. Charming, but you can try this yourself. It's not unusual to see such things in most manufacturer data. It depends how the data is produced. In this case, presumably each parameter was the average of a test batch, hence the variations. Providing these are not large / are within typical manufacturing production tolerances, (which I believe for TB is +/-10%), it's not a big deal. In general, it's good design practice to err on the side of caution & slightly over-size the box for the desired alignment, whatever the driver might be. When you get large discrepancies (say > 10%), that's when alarm bells should be ringing. That is not the case here however, so I can't see why you seem so upset. In my experience, the only major companies who regularly appear to get entirely consistent data in their sheets are Seas and Scan Speak.
Sorry, I don't use PMs on the forum. 'haven't for a long time.

Can mods please erase this spam starting from post #39 that I provoked? It has nothing to do in this thread. I apologise.
@ Scottmoose
turn on the pm and then we can talk, if you even want.

The TB W8-1772's are among my favorite drivers, but the W5-1611sa is not. If the new driver is like the 1611, it will be flat, uninvolving and lifeless. But it will beam like a flashlight.

Flat for shure, almost ruler flat on graph, uninvolving and lifeless- I have the oposite experience.
Hi Bob, I never tried the 1772 but I do know the W5-1611sa. I can't say it's uninvolving or lifeless, it really depends on how you implement it.
I did use them as "full-range-mids" in these floorstanders. Below 120hz the W6-1139 takes over and on the back I installed an ambient tweeter that improves off-axis response. This works incredibly well, the soundfield is more airy then most normal two,- or three-way systems. The measurements show the response 20degrees off-axis.
Btw. the W6-1139 is one little beast! I tuned the sub-woofer to 28hz and it really goes lowwwwww, I used a plate-amp to drive the two W6-1139's.

Here some pics with the drivers installed and the first measurements without crossover and without ambient tweeter. You an clearly see the bafflestep around 1.2khz and the peak at 6khz. The decay diagram is excellent, also at 6khz.

There are going to be at least two notches, one for the bafflestep and one for the 6khz peak. I might want to use three notches, one extra centred around 3khz so i can fine-tune the response with the resistors of each notch.
It might sound like overkill but I want to get the most out of these monitors 😉

Nice response measurement. As you do not show response below 200 Hz, what so you expect the bass extension to be with the passive radiator employed? Also can you show the HD plots?
Thanks,

The cabinet looks very nice by the way.

I did do some close-mic measurements of the W4 and the passive-radiator, I 'll post those later. The passive-radiator is active in the 45-65hz range.
I tried to close-mic at the side of the enclosure between W4 and the PR but it wouldn't give accurate results.
I'll try to do some HD measuremnets later.
Thnx!
on-axis vs 20degrees off-axis, lookin' good 😉
Btw. this is the response without ambient tweeter.
Sound so far is beyond expectations, very smooth, the 2nd LCR just takes away the last hint of harshness.

Yesterday I've done some tests with the ambient tweeter.
1.5uf in series does the job nicely, the only thing is that the phase of the tweeter depends on the in-room position....maybe I need to add a switch to adjust the phase of the ambient tweeter 😎

Yep, and measuring doesn't add anything here, it's really a matter of experimenting and listening what sounds "best".
1st listening impression with one speaker.
-impressive fullrange sound, the low tuned passive radiator works great(45hz and up)
-room filling sound, the ambient tweeter does an incredible job, throughout the room the sound stays virtualy the same.
-vocals sound amazing
The speakers have impressed me(and my girlfriend 😉 ), there's no need for larger speakers in your average livingroom.
