Any full ranger will have limitations and all are subject to cone break up. The problem is when you generalize and assume all drivers sound the same when pushed to their limits. They don't. Cone break up is easily measured and looks quite different from driver to driver. I would be willing to bet that if the OP swapped out his AN driver for a 15 inch Lil driver his "suffering" would be largely mitigated.
15 in full range drivers
I built a pair speakers with 15 in full range drivers that drive easily with a 300B set amp. With certain music, (vocals) they are beautiful, but other music can be fatiguing. Wife can only take them at lower volumes. Added great subs to support the base and the 300 B Set tubes, but I am grappling with just investing in a new pair of speakers that are more well rounded or trying to different DAC's and a Equalizer to help the speakers I have. I am thinking like one of the speakers from the Klipsch heritage line would be a great way to go. But getting rid of the ones I made is like putting down a dog that doesn't walk as far as he used to and fells like I am giving up on them. Do I go with new speakers or keep suffering? LOL.

Every example limps as the saying goes. But anyway, below is Paul Miller's measurements of the Lowther Almira which uses an eight inch DX3 driver supplemented by a supertweeter. I've never hear a "full range" driver which uses a whizzer cone to extend frequency response that didn't sound ragged. A 15in driver is going to be very compromised in the midrange - more than the Lowther driver. The best sounding efficient loudspeaker I've personally heard is the Devore Fidelity 096. Expensive, but properly engineered to perform with low powered amplifiers.

I see this is a paper cone. Is there any coating on it? C37 lacquer Used this on my untreated paper cone F-R. Figured I had nothing to loose as the breakups made it un-listenable. Had it shipped from Austria. Put on 1 coat and still harsh. So took a chance and put on a second coat as Dieter recommended and sound was good. Subjectively, I think prefer it over Nextel as it is lighter in weight and more beautiful tone to it. Although I would had to hear side by side, before and after, to say for sure. You can coat most anything with it. Except for tubes. Haven’t tried the C37 lacquer ear drops yet, haha. (that is a joke) Evaporation is a problem and even though I stored it in its original container in the refrigerator, it still evaporated. |
