Cardersound Nina's underwhelming...

40-25khz from a single full range driver in a moderate sized rear horn loaded enclosure?

Pretty meaningless without more detail.

I find it hard to believe there would be no drop off even in the upper ranges below 20khz that some might be able to hear.

TEktons were 2-way, right? THat's an advantage there.

Is there a measured frequency response curve available?

There could be many reasons why bass is not what it might be but I would expect much is not possible with a single 4.5" driver, even if rear horn loaded. That's just basic physics I fear. Same true in regards to dynamics.

The things that sound good do not surprise me. I don't think this kind of speaker is for those who listen to pop/rock or more electronic forms of music, but could sound lovely with many types of acoustic music.

ALso wondering who was the seller? Apparently they saw it fit to reduce the low end spec for some reason. Maybe a side effect of the Enable'd process? Dunno. Can't find much out there about that in general much less anything about potential negative effects.

All speaker designs have tradeoffs. I've looked at the Cardersounds, Cain and Cain's, and other similar designs being a fan of full range drivers and the visual aesthetics in general and having an interest in horn designs and would expect certain strengths and tradeoffs along the lines you describe, but think they could well still fit the bill quite well for some listener's applications and with some kinds of music.

Speaker swaps usually involve other system tweaks to get things right again. If you think they have promise but are just underachieving initially, give it some time and careful thought as to what might be done to help max the new speaks out.

ALso wondering what your expectations were going in jumping from Tekton to these? That would tell a lot. I'm guessing more coherency from a single driver with good extension in line with the advertised specs and at least decent dynamics?

You'll have to pardon my initial rant, and a hasty one it was... My expectations were (are), indeed, exactly as you describe. After listening extensively throughout the day today and into the evening, though, I'm appreciating them more and more. And after listening to them side by side with my not-yet-shipped-off-after-sale Lores, said expectations have been met. Why I felt the need to type up my initial experience without giving them a *truly* thorough listen, I don't know. Again, pardon me. I'll leave it at that.

It is only a fe126e a very small driver. Plus the enable process is a very questionable tweak. I feel you would be better off buying a larger driver than enabling a smaller one.

Well, sure. I suppose I thought the loading of the driver would render more bass than what I'm hearing (which is, again, very little). The EnABLe-ing process had been applied to the drivers already. Part of me wonders if replacing the drivers with stock 126en's might alter the sound for the better, but then again it might not do a darn thing. Again, though, these speakers sound pretty darn "just right" with acoustic music. Rock and roll, large orchestra and electronic music, though, just doesn't work well with them at all... And maybe they're just not supposed to.
