Jbl 2241h vs 2242h


This process pumps air through the magnetic gap and directly over and around the voice coil to provide immediate heat transfer and reduction of operating temperature - a direct improvement in power compression.

The copper ring acts like a shorted secondary turn in a transformer, with the voice coil acting as the primary winding. Patent 5, A typical application is as a subwoofer for cinemas, with extension down to 25 Hz. Careful attention has been paid to the design of the moving system.

The H is intended for use in applications where large amounts of low distortion low frequency acoustical power is required, along with excellent mid-bass transient behavior. The H carries a power rating of watts, as compared with the watt rating of its predecessors. This is accomplished through the use of a voice coil with one-third more surface area than in the earlier designs, allowing the H to dissipate heat more effectively to the surrounding metal parts, The higher power rating, reduced power compression, and increased efficiency give the H a net continuous output capability that is 3 dB greater than that of the H.

The cone used in the H is reinforced with fiberglass for added strength. Short-link Link Embed. Share from cover. Share from page:. More magazines by this user. Close Flag as Inappropriate.

I'm really not concerned with performance above Hz as I will be crossing over to a full range driver above hz.

In my application, higher the efficiency, the better for me. Are these drivers not considered "musical" or "audiophile" enough? Ultimately, I don't want to spend alot of money trying snowrunner azov 5319 obtain TADs or AE TD15 or even the JBL H, when one would not be able to tell much difference between the performance of these speakers over the 30hz - hz range.

Any thoughts? Pretty sure that it was answered times before ;- Look below. Similar threads. For Hz, I would definitely go with the if 10 cu ft isn't a problem. Add the small powered sub of your choice to drop below 50Hz? What is your "full range" upper range device? Originally Posted by Lee in Montreal. Originally Posted by Mr. Originally Posted by dkalsi.

It's not a musical woofer. One note bass. But I am sure it will give you great Hz.The H is built around a completely new motor structure with a pole piece extending both above and below the top plate to improve gap flux symmetry and increase thermal conductivity from the voice coil to the pole piece.

In addition to the benefits of JBL's Symmetrical Field GeometryTM, the H also incorporates a copper shorting ring that is imbedded in the pole piece at the precise center of the gap and is in close proximity to the voice coil. The copper ring acts like a shorted secondary turn in a transformer, with the voice coil acting as the primary winding.

The benefits of this are a reduction in third harmonic distortion and a reduction of the voice coil's inductance, which improves the transducer's transient response. The H can produce peak instantaneous outputs of dB above Hz measured at one meter, greater than any other JBL low frequency transducer. The H carries a power rating of watts, as compared with the watt rating of its predecessors. This is accomplished through the use of a voice coil with one-third more surface area than in the earlier designs, allowing the H to dissipate heat more effectively to the surrounding metal parts, The higher power rating, reduced power compression, and increased efficiency give the H a net continuous output capability that is 3 dB greater than that of the H.

The copper ring acts like a shorted secondary turn in a transformer, with the voice coil acting as the primary winding. The benefits of this are a reduction in third harmonic distortion and a reduction of the voice coils inductance, which improves the transducers transient response.

The elder Martini was a coal mining engineer, and his work required that the family moved about quite a bit during Lansing's early years. Lansing was the ninth of fourteen children, one of whom died in infancy. For a short time, Lansing lived with the Bullough family in Litchfield, Illinois. He later took their name when he changed his from Martini to Lansing. Not much is known about Lansing's early days, and we are indebted to Bill Martin, one of three surviving brothers, for providing most of the information presented here.

Lansing graduated the eighth grade at the Lawrence School in Springfield, Illinois. He also attended the Springfield, Illinois, High School. Later, he took courses in a small business college in Springfield.

As a young lad he was very interested in all things electrical and mechanical. At about the age of 10, he built a Leyden Jar which he used to play pranks on his playmates. He also constructed crystal sets, and at one time, probably about the age of 12 or so, built a small radio transmitter from scratch. The signals from this set were apparently strong enough to reach the Great Lakes Naval Station in Illinois; naval personnel determined the source of these signals and later supervised the timely dismantling of the young Lansing's radio transmitter.

For a while Lansing worked as an automotive mechanic, specializing in fine engine repair work. He attended an automotive school for mechanics in Detroit through the courtesy of the dealer he worked for in Springfield. Lansing's mother died 1 November at the age of 56, and at that time Lansing left home. As best we can determine, he went directly to Salt Lake City. At the time he was working for a radio station as an engineer. In addition, he worked for the Baldwin loudspeaker company in Salt Lake City for a time.

All it does is to give the coupling efficiency between the air and the speaker driver a boost. Drivers and horns essentially serve to match the impedance between the low density of outside air and the high density zjinnova zlink the speaker horn diaphragm. Drivers and horns are perhaps best put to use in concerts and PA systems, where sound reinforcement is needed.

Cabinet horn loudspeakers are also popular in concert venues, as they are able to reproduce high volume bass sounds. Drivers and horns have other, more specialized uses.
