Not everyone wants refrigerator -sized sub cabinets and most large subwoofers with huge Xmax don't have the agility to keep up with full range and open baffle speaker systems. Dyna-fone does. Designed with a powerful motor to run in a ~30L cabinet, sealed for best transient response. Rigid cast aluminum basket.

10"(260mm) to basket rim edge. Alloy cone. 200/400w program/power.

TSP parameters and impedance curve

Frequency response here.

Sound: Articulate. By keeping the Xmax to 14 mm p-p and using a well-damped non-flexing alloy cone, rigid aluminum basket together with a powerful motor, the Dyna-fone is able to keep up with the fastest open baffle or wide range drivers like the Ciare and Neo-fone but still have serious useable grunt down to 25hz.. You can see from the impedance plot that there are no nasties above 2k and smooth response below. The attached measurement graphs were taken at the factory in an anechoic chamber BUT, as the factory is wont to do, with totally green drivers. We'll take some TSP measurements on a run-in pr in a week or two. As the spider and surrond loosen expect the Fs to go down a bit and efficiency/VAS to go up a bit.

$96USD/pc plus shipping air express $80USD/pc most places Europe/North America (7kg each, ouch!) Email to discuss cheaper shipping options (or combined lots of multiple drivers) to your area

Together with the Ciare in small open baffle (13 x 14" and the Ciare dual magnet can cover to 70hz, no suckout in the 100-300hz region), plate amp as below for a cheap killer open baffle system. ($96+$149+$110 for a single sub open baffle system). Or can be used with the Neo-fone also in a sealed box for matching transient response ($96x2 + $149x2 + $100 for a dual bass setup with the Neo-fone .)

Bass without blur

 

  • impedance 4 ohms
  • frequency response 80 – 20,000 Hz
  • power handling 60 watts rms
  • power handling over 80 Hz/24 dB 80 watts rms
  • power handling over 120 Hz/24 dB 120 watts rms

playing these now and they sound way too good for their price. Easy to drive; ideal match for Ella, even a 300b amplifier for moderate listing levels.

 

The best enclosure shape:
Sphere-- has the least coloration

The best enclosure material:
Ceramic-- with spherical shape very nearly inert

The best speaker concept:
Coaxial-- offers the best one point source from every angle.

Best crossover frequency:
No crossover would be best but in this price range full range speakers cannot reach the overall quality of the S-22 coaxial. The bass-mid speaker has no crossover. The tweeter has a 12dB high pass for high power handling.


Best placement
The floor stand T-70 holds the sphere "free air". The wall mount M-10 also offers good decoupling. Included table stand (as shown at left) made from steel with black powder coating.

Reckhorn Subwoofer Amplifier: This is what we wanted all along. Mounted outside for better cooling and accessibility. There are many cheap plate amps with inflated specs. This is not one of them. German technology shows how it should be done. No guts, no glory! Everything is overbuilt and only the best devices used so that real performance meets and exceeds specs. What parts make good subwoofer amp? Output devices must be capable of current delivery without distortion or sag. The Reckhorn uses 4 x Toshiba devices, 6 x 10000uf caps for on-demand power AND a huge torroid power transformer. Shipping is by airmail to most destinations (email to confirm, 1 to 2 weeks), for express delivery email for rates

Taming the bass in any room is a story of peaks and valleys. Get the important 60hz region right but 40hz has a 15db valley then comes charging back +10db at 30hz. And look, there's a 10db hump at 70hz! No problem with the Reckhorn. That valley? Just adjust the boost and waltz that lift anywhere between 20 and 80hz. The peak? Dial in the EQ function to cut it down to size. Boom? Again, adjust the subsonic setting to whip unruly bass into shape. And, 24db roll-off to get out of the way fast. Connections here
