The measurements in my simulation are actual measurements. What I'm uncertain of is if the model is working in the cross over region.
And I say that loosely, as 9/10 the simulation works great.
From 500hz and up, it's real. You can see how flat it is. Stays within a 5db window. Sorry I cut off the 10khz+.

I gotta disagree with Cogitech though. The bass is where these things don't work. Hardly any bass. Kind of humerous in fact. But I didn't try hard to make bass out of them.

What?

Then my cabinet design must be fan-%^&$#-tastic?!!?

Did you see/hear my bedroom setup on a proper set of speakers? The bass is insane for a pair of 3" speakers!

Oh, I understand now.

I might have to see if I can get a set of those! I want to have a few things to try when I get my TV speakers together. They'll likely be a FAST as well with EL166s.

Yup, that's them. I meant the bass I got from them wasn't very good. I suppose for a 3" it was ok. And that was based on listening to mine. I can't really tell what yours sound like. Very likely you know how to built a cab better than me. Not really my thing

Can you give us some details on your cab? Mine are just sealed of course. Like 4L or something.

HAHAHHAHAAHAaaaaa. Sorry. That was funny. I am a complete cabinet design noob. I was being sarcastic above.

Anyway, I have played the audio from that video through my main living room system. Anyone who does similar will likely be shocked how deep those little speakers in the video can dig.

Mine is a 13-ish litre, extremely long, thin tower design, ported and tuned to 52.5Hz with some accidental QW and/or TL action going on. 90% of the reason they sound so good is a combination of luck and stuffing.

A quick google confirmed that I am not the only one who has been able to coax a great deal of bass from these little wonders (albeit not at huge SPL).

Sorry for off-topic, but the build thread..."nanoTower" - Tang Band W3-881SI

Ah, thanks for the link to your thread. I get ya now. Ya, my sealed alignment is maybe hitting F3 of 120hz. Maybe. Which is just fine for my use. The most impressive thing to me about these is the frequency response. Very smooth/flat/extended. No beaming issues either.

The silver flutes have a decent xmax and seem to be able to take a punishment. I'm not particularly blown away by the silverflutes up around 1khz, but from 300hz down they have nice kick and stay very linear with loads of abuse. I'd MTM these tomorrow if I didn't have to order a pair. Then I could crank the crap out of these.

Sorry this took me so long. I'm rarely on my measurement computer lately. Someone asked about measurements. And hopefully this will help someone interested in the little TB. And the silver flute I suppose. I have better data than this on the SF.

Anyways, red is the system on axis. This is indoors so I don't have much choice than to gate out everything below about 200hz. 5ms gate time.

Blue is the woofer nearfield. It has a low pass of 300hz LR 24db/oct, so really anything past about 450hz is the tang band sneeking in there. Use your imagination and connect the two. Right at the cross over so don't want to splice them.

Really flat all the way up Listening to Miles Davis right now and it's so sweet.!

The success of this build reinforces my suspicion that if one wanted to build large inexpensive, albeit, not very transportable speakers, use 2x4 in wood framing with gypsum board drywall. All you need is a miter box, hand saw, utility knife, and some drywall screws and a drill. You can make very large - wall like enclosures. Now, building the speaker with drywall allows you to really enhance it by designing in to the drywall structure, transmission lines, horns, etc.
