Has anybody used any of these products, Drivers and horns?

Re: Has anybody used any of these products, Drivers and horns?

I've used DDS Horns and been quite happy with them -- you'll probably find quite a few people here who speak well of them. I haven't used that particular model, though. As for Radian, I've used their ceramic magnet-based drivers and been very happy with them -- they have a smooth, sweet sound. I did notice that the new neo model has a very nice looking response graph. There's some opportunity for hanky-panky with smoothing, but if the chart is a fair representation of the driver, then it's definitely worth a listen.

The RCF HF94 is what is installed on the dB Technologies DVX DM12 boxes (maybe others with the 90x40 horn). The DVX DM12 uses a RCF ND651; it also had a Art700 marking as well.

For being a powered speaker; the horn sounds good and it can cut through with a rock band.

Alan,

I had a lot of experience with the B&C ME90 before I started working for them, and I always thought it sounded excellent and had excellent way off axis frequency response, even when crossed fairly low.

B&C DE900, the current version is the DE920TN. The 820TN is the less expensive version. There will soon be a DE980TN with improved HF consistency and waterfall, but it's not available quite yet.

82tn is ceramic and the 920 is neo. Whats the difference between the mmd3atn8 and the mmd3ctn8m? Whats the a, c, ending m stand for?,,, If you can reveal that info.

...and while we're picking Bennett's brain, why did they create a titanium version of the DE250? The non-titanium version has higher average sensitivity and a smoother, more extended response... why mess with a good thing?
 
Re: Has anybody used any of these products, Drivers and horns?

Alan,

The A, B, C, and D stand for the generation of the diaphragm, more or less. They are not necessarily physically compatible, and the latest (D) diaphragm certainly requires the correct phase plug to operate properly. Every driver in our line has a specific diaphragm designed to work with it. The M stands for push button, as opposed to spade, terminals. We only stock push button here in the US, except where impractical (e.g. on the DE7).

Please note that I was talking about the DE820TN, not the DE82TN. There are new ceramics as well, the DE90 and DE95.

Hey Chris,

The DE250 is certainly a popular product, sounds great and takes a beating (IMHO!). Some people prefer the sound of a titanium diaphragm however, especially in these smaller diaphragms where the resonant frequency of the dome is almost ultrasonic. The titanium diaphragm actually has a more extended and accurate HF response than the polyimide diaphragm, even if it is rolled off a little more. In the past, customers desiring this more "hi-fi" high end had to go with the DE500, which is considerably more expensive and uses a neodymium magnet. Now they can have that same sound in a ceramic magnet driver, at the same cost as the existing DE250.

Looking at it again, I see what you mean -- the polyimide diaphragm does seem to drop like a rock, while the titanium one looks like it's got a bit of life in it past 20k.

Bennett,

Whats the difference between the mmd3atn8, it says Titanium throat, mmd8008m says polymide / Titanium throat, whats the polymide mean?

Alan,

Polyimide is a plastic-like material. In our hybrid diaphragms, like the MMD8008M, the surround is polyimide and the dome is titanium. On our all titanium diaphragms, like the MMD3ATN8M, the surround and dome are titanium. The difference is mostly for sonics, although I've been told the hybrid diaphragms are somewhat more durable. Many of our drivers are offered either way, but the latest batch (DE980, DE1080, etc) are only offered in full titanium.

These photos should make the difference clear, full TN diaphragm on the left.
