Audiozen, because Arial's tweeter has two large ferrite magnets instead of neodymium magnets it has better detail and dynamics? You have no idea what you're talking about. |

I was considering buying the SS-AR1's, and feel sorry for those who took the plunge, and will be buying the Aerial Acoustics 7T's as soon as my sound room remodeling is complete. I heard the AR1's while I was in southern Calif. and was impressed, but after hearing the Aerial's in Portland at Fred's, the Sony is no match against the 7T's which blow the Sony's out the window. Best transparency and mid-range clarity I have ever heard. The bass was powerful, rich, very deep and very tight. Aerial's tweeter is an in house custom design, built by Scan-Speak, who also provides drivers for the Sony AR1's. The 7T midrange driver, is also a in-house design, built by SB Acoustics in Wisconsin who provides the mid-range drivers for all the Wilson Audio speakers including the Sasha's. Michael Kelly at Aerial informed me the 7T's mid-range and bass performance will equal or better any speaker regardless of price. They are that good. Before you plunk down $27K for the Sony's, check out the Aerial's and listen. You will be amazed at what you get for $10K, and think twice about buying a more expensive speaker.
Audiozen (Threads | Answers | This Thread) I was considering buying the Aerial Acoustics 7T's, and feel sorry for those who took the plunge, and will be buying the Walmart 14T's as soon as I find a job. It's has the twin turbo quad cam carbon fiber drivers made by Acme Corp that is just amazing. You will be amazed at what you get for $100, and think twice about buying a more expensive speaker. |
Knghhifi..The speakers made in Mexico at Kmart are a better deal than the one's at Walmart. |
Face..there is very little audible difference between a neodymium and ferrite magnet. It would mainly apply to air chamber differences. Neodymium became the rage in the 90's due to there higher magnetic flux, and the ability to move current three times faster than ferrite. China currently has a monopoly on neodymium, and it is far more costly than ferrite material since its a rare earth metal. The main benefit is that less mass is required with neodymium than ferrite, resulting in a lighter, more compact driver.
Large ferrite magnets are like capacitors, and can handle larger voiumes of continuous current. The tweeter in the Sony's have a maximum rms rating 0f 90 watts. The tweeter in the Aerial 7T can handle 200 watts rms without breaking a sweat, due to there large magnets and there one inch copper voice coil. Neodymium's overheat more easily than ferrite, so avoid clipping your amp. You will destroy a neodymium if it overheats, which is not a problem with ferrite. |
Where are you getting the 200w figure from for the 7T's power rating?
Sony's 90w rating is 100h(hour) RMS, not peak and 150w long term max-power, which means they're capable of playing music at a constant 114dB @ 1M each without clipping. Add in Sony's higher crossover point and power handling should never be a concern unless you're attempting to fill a very large room or trying to make yourself deaf.
I'd still like to know how any of this have an effect on dynamics as the woofer(s) are usually the limiting factor on overall efficiency? Or as you mentioned before, detail? |
