【 Weak current College 】 audio playback is in pursuit of a sense of relief---Power By 【 China power house network 】

To me, the sound can have dynamic sense is very important, this dynamic fluctuations will ultimately determine the vivid and lively music. Of course, I agree with undulating interested others may not be able to understand, but this clearly and my personal view and the music and sound awareness.

Not only did I like classical music and jazz, but also love to listen to rock and roll, pop music, sometimes I will use a large volume to play the music, because I have undulating interested in addition to the requirements of sound nice addition must be strong.

From the late 70 's to 80 's to the United States as the Center, along with hi-end reproducing the sound of pop, emphasis on sound positioning and true reproducibility, that is to pay attention to the music of audio-visual style more and more popular, even if that was the sound of the highest priority topic ideas. However accept that kind of sound, tend to feel and understand the changing music reproduction interested is my most vexing, but in fact sound completely reproduce musical sense, the body naturally follow swing, you should not think of how audio and video.

Sound too refined, broadcasting becomes plain water, really boring, adhering to the United States hi-end audio genre of speakers also vary greatly in the past, more and more able to render out the fairly vibrant sound, THEL, WILSON AUDIO, AVALON, MARTIN LOGAN ... And so, compared to the start, the latest products of the sound is very rugged.

General explanation of undulating, with average hearing level, relative to the direction of high level, low level direction was identified in a linear good replay status, most weak tone to clear the replay is the highlight. For example, Claudia Black Diou Abad conductor of the Berlin Philharmonic Orchestra for 威 rain the Requiem, if you put the following at the beginning of the volume level is too high, after the outbreak of the climax would be difficult to have an amazing performance.

In order to put the Requiem have ups and downs are replayed, replay system must ensure that the full force of the maximum levels, but in fact, we hardly consider to original size replay orchestral, realistic requirement is relatively small, so small fluctuations are small, medium, there is a sense of relief, medium if the use of small speakers, because the accent was too high to bear, timpani and percussion sounds of continuous is too low. If you need to increase the volume to maintain alive, which means that the entire system of ups and downs are inadequate.

On the other hand, continuous weak tone of rock and roll (of course there are exceptions) replay, apart from the average hearing level set to high, how to set the maximum level set in the Replay system ceiling, but also to gain better listen to the replay sound, musical rhythm elements react especially important. To truly to play the powerful bass, miniature speaker, obviously cannot be met, in the dynamic range of the maximum limit that large speakers certainly beneficial. In fact, equipment bass unit diameter in 30cm (12 inch) above the speakers reproduce the dynamic range of supply capacity is very strong. Fitted with a horn speaker very undulating, baritone above use the dome or tapered direct radiator or drive-Horn also changes a sense of relief.

Like to listen to jazz and rock music, I think more than the use of horns in the treble range of speaker systems of music especially strong. Device with Horn speakers have dynamic range adequacy, most far exceeded all radiating speakers. Incidentally, JBL has been actively used varying is curved radiating Horn Horn dyeing techniques, thus effectively of JBL speakers with Horn cell system until now still in widespread use in the field of electroacoustics.

Fitted with a horn system sounds may not experience a Zheng Ning impressed, but this young for persuasive play rock music was able to give a sense of dynamism. JBLprojectk2s9800 with s5800model4348 and westakeaudio bbsmi5ftowerl2towerhr7 of, what I most like to listen to the sound of feeling full of ups and downs. Especially when a large volume of JBL's good sound replay is off, a sharp increase in the volume increases, the degree is a way to let the listener in high spirits.

With this speaker, to perfect the replay jazz, rock and pop music. In the case of CELESTION SL6, 1980s is a small 2-way Bookshelf-a very popular, after extended shelf-type speaker tall floor-type speaker dock, now almost this type of heyday, which is equipped with independent subwoofer unit, develop into 3-4-channel models can be said to be a small caliber bass unit-based, it is worth noting that they have a large dynamic range.

To me, I like the last stage output parallel transistor low power amplifier, low-impedance speaker had fads, power amplifiers can be unbroken output strong power became a problem, in order to ensure low impedance of the current supply capacity, and uses the enhanced power and enhanced output part number parallel tubes, but to make the speaker can really play out energetic, have a sense of sound flow, but is not that simple. One of the most intuitive feeling is the driving force, despite high manipulation, but the sound is dull, cold hard.

Power, the greater the better, but much is best? decide and speaker efficiency, if sensitivity 90dB/w (m) speaker 300W power is needed, and 100dB/w (m) speaker just 30W can get the same sound pressure. A jazz tea room's customJBL system drive 2208B + 375/537-512 + 075 unit is composed of 40w/CH transistor amplifier consisting of multistage amplifier driven, and jazz can be dynamic.

On the contrary, to have low efficiency of speakers play the sound of rolling sensation, power amplifier requires considerable impetus. My audio-visual room using JBLS7500 plus GEM (now KAN SOUNDLAB), TS208 (standard type) × 2 3 road system, and driven them is GOLDMUND's 3CH power amplifier.

Since the speaker is a double bass of the S9500, so specifications in addition to this option, no alternative. But the S9500/S7500 1400ND bass unit resistance of about 6 euro for parallel driven S9500 minimum resistance can be lowered to 3 ' or so, so even with 125W/CH double tube parallel push-pull amplifier also reduced due to impedance push a bit hard.

Relative to S7500, SR3 can without any problems and drive direct continuation of the low-single-unit. In order to add GEM of belt type treble speakers from the original S9500 changed to S7500, results and SR3 match better. The conclusion is the key to getting a sense of relief is the speaker, but their unique style of the amplifier, of course, the front-stage amplifier and signal sources can not be taken lightly.
