Good afternoon Gedlee,

For example, consider these two drivers: The Peerless 830884 8" The Eminence Beta 8A 8" Here we have an example of two drivers that could be considered good, but have different goals. The Peerless would not be the best choice for high SPL applications, and it looks as thought it would have to cross over lower comparatively. It does however appear to have smoother response through its usable band (though the resolution of the provided data is not great!) and a bit more low end extension. In my opinion the Peerless would be the better choice for a modest SPL, comparatively near-field application, where the Eminence driver would be my choice for higher SPL, and higher dynamic situations such as large room live-performance oriented system or high quality home theater. Certainly a random comparison of two drivers at face value is not to be taken as proof that prosound drivers aren't for use in hi-fi. That's not what I mean at all and I bet the systems you've put together with prosound units have great SQ and the rest. But my (rather long-winded!) point is that I am not certain even great prosound drivers are the best fit for every requirement. Quote:

It would be very interesting to hear the Peerless and the Eminence compared in the same 3-way rig. Certainly a worthy experiment.
I have heard the Beta-8 used as a midrange with only a small inductor to flatten it. A really nice driver. Much more "refined" than you might think. Wonder how the Peerless would compare. Less efficient, but other than that? .

but then i also don't consider dynamic headphones to have acceptable treble sound quality. and when i heard electrostats they didn't have acceptable treble sound quality to me either. hm ... and i only hear to 17 khz. i wonder what guys who hear to 22 khz think LOL. if i can hear the difference between 1" alu/mag dome and 1" titanium dome then i certainly don't want to be listening to 1.75" metal dome ... i would gladly take a compression driver with 1 inch VC, 1/3 inch throat and a 5 slit phase lens. but who will give one to me ? i can't afford JBL Everest

I agree with Borat, 1.75" metal dome just can't sound good, it has distinct metalic resonance. Although a piece of foam, like in gedlee's system, should absorb most of the resonance. The only compression driver I'd get is BMS, because it has extremely well damped ring diaphragm.

Everyone has different tastes. <shrug> And I don't like most tweeters, either.

With you on that Mike, and my whole affair with horns and HE in general started with the JBL 075/2402 annular ring radiator horn tweeter. I've had both alnico and ferrite. Currently using the 2402 ferrite version. It's not perfect, but there is something about it that I find rather appealing.

The ring diaphragm is no better damped than a dome. Its just smaller and therefor lighter. |

Oh No! You'll lose a whole octave!!
![]() I actually like stuff that is rolled off about 12-15K. Systems that go higher sound fake to me. Too sizzly. I just don't hear that stuff in real life. But everyone's ears are different. Yeah Kevin, we are on the same page. The horn stuff isn't perfect, but done right it has a realism that few other drivers can approach. .

A good question!
I just don't find that much difference. I hear/feel most of that impact down lower. Rock kick drum does have a lot of HF energy, at least mixed live, but it it doesn't go above 10K, IIRC. Getting the crossover phase and horn position right has a lot more effect on the impact. For me, at least. |
