小弟而家套CAS組合

聽勁歌快歌反而無呢個問題
例如 ... 安室奈美惠 D快歌 ... BASS好清晰

但係聽"部份"慢歌情歌去到BASS會出現 "BOOM BOOM 聲" 問題

蔡琴 老歌專輯 - 是夢是真
林峰 - 我們很好
張敬軒 - 斷點
張國榮 - 紅 , 偷情 , 追

無論透過 CAS 或 CD 播同一首歌都係咁

you need some room EQ

The "Boom" sound is likely caused by standing waves that depends on the dimension of the room

You may use CDs with test tones at multiple frequencies (30,40, 50Hz .... up to 100 Hz). The frequency that causes the standing waves will sound loud.

You many reduce the booming effect by re-positioning the speakers and putting bass traps (or thick carpet rolls) at the corners.

The ability of the amplifier to fully control the bass energies of the speakers is another factor to consider (though, may be to a lesser degree).

Inserting an equalizer may help to manually suppress the booming frequencies, but it may cause other distortions.

我兩個喇叭都出現 "BOOM BOOM聲"

唔係單係左邊係牆角位喇叭先係咁

至於加地毯係唔係真係可以改善 ?

試下將amp, cd機, 等逐部放落地 .

My suggestion is based on the assumption that booming is caused by standing waves - i.e. the environment. It is not uncommon for the relatively medium to small sized listening rooms in HK

To verify this, you can use a test CD as explained before. You may also try to place the setup in a different room to observe the difference? For instance, is there similar problem in the demo room?

Floor Carpets can absorb mid frequencies , and may not help much with booming Bass. Placing a Roll of thick carpet at the corners may ease the problem. The official solution is something like the ASC Tube Trap or DAAD4 that you can search for more information from the web.

Also note that some CDs are produced with very rich bass responses to "simulate" an unique atmosphere, and these CDs could lead to more booming.

C-Hing, I search your speakers EPOS M5i on internet, and saw one review. If the review is correct, it maybe the speaker's design problem. PM me if you want to see the link, or you can Google "EPOS M5i".

hi apprentice

pm左比你

thanks

By the wau, where can fine CD with test tones ? Thanks.

if you are not in a hurry, pm me your address. i mail you one when i'm back to hong kong. i made these myself. there are other tracks as well as frequency sweep.

比卡超 C-Hing, pls check PM. Thanks.

Booming caused from the speed and room size

Sinking caused from the tits and butt size

very good~

笑左。。。

老牛啃嫩草 食到"BOOM BOOM聲"！

行埋果陣骨女「room size」太大而樓主完事「speed」太快唔應該有「booming」
