Balanced mode radiators (BMR's)

BMR drivers combine bending wave technology with pistonic motion to create full audio range, wide-dispersion speaker drivers for life-like sound reproduction.

A je pri 8 colarju možen takšen razpon? Če bi imel nekajkrat višji Qms, bi bil res totalna špica, kljub temu se lahko ostali breitbandlerji skrijejo:

20 DE8 is a speaker exception. It was designed by Michel VISAN founder DAVIS acoustics, which proudly claims 45 years of experience in the field of speaker. This project Broadband "ultimate" is the culmination of a career dedicated to high fidélité.Un year has been necessary to develop this HP!

20 DE8, like any good broadband can be mounted in a cabinet plan. Not only do you enjoy listening without filtering, but you will not sound cash. Total freedom that leads to a listening absolute transparency.

However, Davis is working on a more complex load to run the speaker, and thus offer a more compact solution. This column will be available later in the year 2012.

Here are the parameters of this speaker:

- Fs: 33.38 Hz
- Re: 6.51 ohm
- Res: 29.29 ohm
- Qms: 1.83
- Qes: 0.41
- Qts: 0.33
- Vas: 175 L
- Mms: 9.5 g
- Cms: 2402 microM / Newton
- BL: 5.64
- SPL: 93.9 dB
- S: 213 cm2

HSB-21"

http://www.exdreamnet.de/magazin/index. ... &Itemid=57

Die Membran ist ein perfekter Konus (also keine NAWI-Membran), die Staubschutzkalotte ist mit 180 mm Durchmesser so groß wie ein normaler Tieftöner. Die Textilsicke ist 4-fach gewellt und erlaubt so auch hohe Auslenkungen.
Der Alu-Druckgusskorb wird mit 8 Schrauben am Gehäuse befestigt. Die Verbindung zum Magnetsystem geschieht über 5 breite Streben. Der Magnet hat einen Durchmesser von 220 mm und ist 38 mm hoch. Darin bewegt sich eine 100mm durchmessende Schwingspule, die Dank 32 mm durchmessender Polkernbohrung ordentlich Hitze wegstecken kann. Die vordere Polplatte ist 12 mm hoch, der lineare Hub beträgt +/- 8mm. Die Zentrierspinne ist nicht hinterlüftet.

Der HSB-21 ist exklusiv bei HiFi-Selbstbau erhältlich und kostet schlappe 250 €/Stück + Versand. Damit ist er in der Riege der 21"-Chassis ein echtes Schnäppchen!

Ali je že kdo uporabil tele enote; http://www.audience-av.com/parts/A3.html ; so uporabjene v projektu 2+2 http://www.audience-av.com/loudspeakers/index.html
predvsem me zanimajo male FR, ki ne potrebujejo kretnic!? ker je cena teh A3 cca 190 EUR/kos, pa še ni jih za dobiti; me zanima, kaka alternativa?

hvala za nasvet!

Audience je zanimiv FR driver, zelo dobro skonstruiran:

Edina alternativa bi mogoče bila BMR.

FAL C90 N48 Neodymium £1,530.00

The FLAT driver is defining the future. If you are looking for a highly acurate soundscape, perfect phase, and unbelievable depth and spaciousness, FAL is your speaker.
Theoretically, flat speaker designs should produce the most realistic sound. Iwao Furuyama, "soundmeister" and the president of FAL CO., LTD., has been striving for the ideal flat speaker system for twenty years. He made his final version of the innovative FLAT engine using a strong magnetic circuit instead of a conventional network. There is no longer any phase lag. In addition, the new FLAT engine has a incredible sound that you could never get from a conventional cone, horn or condenser speaker. In other words, only the new FLAT engine can reproduce the depth, feel and texture of each instrument or voice, with well-balanced imaging. You can enjoy dynamic and ultra-natural sound for any genre of music. Thanks to the systemization of the FLAT engine, energetic pianissimo is also sensitively reproduced. The deep three-dimensional soundscape by the FLAT engine gives you the deep impression that you are sitting in front of actual musicians.
The new, small, FLAT full-range driver unit is a breakthrough in next generation audio speaker systems.

High-resolution sound quality is not a conventional speaker, clarity of high-speed, three-dimensional sound localization.
●Evenly in order to release without delay all frequency bands from the whole area of ​​the diaphragm, eliminating by the time difference of the sound "muddy", can play a more faithful.
●The ideal diaphragm of requirements is a lightweight and strong, also including more air inside evenly. Developed a special foam to clear these conditions.
●Foaming was uniformed throwout 4mm thickness diaphragm, natural honeycomb structure designed. Minimize the degradation due to aging and resistant to moisture.
●Square foamed voice coils are double winding internal and external, the magnetic circuit is installed only the long edge side of coil. Therefore, less likely to cause inductance, can be realized simultaneously flattening impedance and frequency response over entire band.
●N50 neodymium magnets are employed, consisting a strong magnetic circuit. Minimize the unnecessary movement of the voice coil, has been acquired with high transient response without phase shift.
●Edge has adopted a durable synthetic leather is subjected the double edge to sandwich around the perimeter of the diaphragm. As a result, reduced to tiny twisting behavior of the diaphragm and the piston smoothly.
●Network (contribute to the audio signal can interfere with sound quality) is not employed full-range design enables the faithful reproduction of music signals sent from the amplifiers.
●In general, speakers of the sound radiation angle is about 60 °, however FAL flat driver's angle is 120 ° or more. Broader representation of sound, so even stereo area is vast.
●Cone-type speakers to reproduce the bass by just the outer part, smaller size is difficult to reproduce rich bass sound. FAL flat driver unit to play through the whole diaphragm, can reproduce enough bass even small size. (Comparable to 38 ~ 40cm woofer)
●Generally when playing small volume, the output from the amplifier due to the smaller, harder to run the speakers treble and bass range. On the other hand, FAL flat driver unit of the diaphragm is small and lightweight to be coupled with a powerful magnetic circuit, bandwidth can not tip the balance even at small volume.
●Because of its high efficiency 97dB, useful from output 2.5W amplifiers.
