Re: ~ 5" Coaxial drivers?

Erin why no love for the b&c? The de7 compression driver is small-. 75 inch so off axis would be good. I have a de5, which is the .5 inch one and it sounds really good. Plus b&c has solid engineering and factory data. The voice coil test the other month would ha e the off axis data too.

Re: ~ 5" Coaxial drivers?

Shoulda just called me. I could have sent you one. I'm using three Q100's up front temporarily at home (in addition to two for background music in the bedroom), which means I have a spare.

I would have, if I knew it. I’ll PM you.

Also the neo motor, and the 3001 has a plastic basket whereas the Q100 has an alloy basket. And the cone material is different; the 3001 has a plastic-looking collar and then a paper cone. The Q100 has a metal cone. (But one of the best-controlled ones around, especially considering the price.)

…

Not quite. Remember that the 3005 KEF eggs are "full range" little speakers. As a practical matter, they go down to about 120Hz. And they're fairly inefficient. Not dedicated mids, really. And the HTC3005SE (I'm using two of them as side-surround) "center channel" is not a 3-way design but a 2.5-way design. (They claim both in different places but after tracing the xover it's clearly a 2.5-way.) I don't know if the driver part number is different.

Yea, unfortunately I didn’t see this mentioned in literature anywhere. The plastic basket seems of concern. Seems it may be subject to flex if the excursion is high enough (whatever that is I do not pretend to know). Sucks about inefficiency but I’ll have to see what the data says before I get concerned about it. I’m fine with mid 80’s. Below that and it starts to be a concern.

Looking at the center, it certainly seems more like a 2.5 way than a 3-way.

In the DIYA LS50 thread, Jack commented that the thin surround of the 3001 was the transition to the Z-surround.

I didn’t catch that. Good to know.

I wonder the context for that. I can think of way more than three. Maybe he just meant three 5" midwoofers?
In the latest generation, there are 5 platforms: the 5" midwoofer (Q100/R100/LS50), 5" midrange (R300+), 5" flagship midrange (Blade), 6.5" midwoofer (Q300/Q700), and 8" midwoofer (Q900).
And then the older ones (the 6.5" Reference midrange, the 3" one in the 1005-series, the 4" one in the 2005-series, and the 4.5" one in the 3005-series). And the in-wall ones, etc. So there are a lot of Uni-Q's.

Yea, I’m not exactly sure what the context of that was.
I’d love to get my hands on all the different Uni-Q drivers. I’m curious how tiered in performance the drivers are relative to the cost of the speakers they come as part of.

At any rate, I'll be back in a couple weeks. We're going abroad tomorrow. And coming back with new rings on our fingers. Cheers.

Congrats. Enjoy your trip.
