9F推: 2.0講立體就算了，環繞？？10/16 13:31
10F→: JBL這種賣多媒體喇叭賣的比Hiend還開心的廠牌根本是自甘墮10/16 13:33
11F→: 落，你怎麼可以買呢10/16 13:33
56F推: 我就說JBL自甘墮落了，曾經的Everest 也是越做越偷懶10/17 00:08
307F推: 喇叭好壞我會看低音，高音這個用什麼單體就什麼聲音的，箱10/15 07:39
308F→: 體設計的功底跟低音差老遠，怎麼會去看高音咧10/15 07:39
39F推: Sabaj 20d/20a*2 前+後級二萬內可組成mono10/13 16:03
33F推: 不懂你並聯幹嘛？ 負載沒這麼重載，你源頭的線徑也沒這麼10/07 23:41
34F→: 粗，用成這樣跟真的是跟裝了MUGEN晴雨窗馬力加5匹一樣10/07 23:41
35F推: 要這樣搞直接用歐規無融絲斷路器+開關盒好了，並聯有現成10/07 23:46
36F→: 的並聯銅牌可以用，直接裸線上去鎖不是更快更生猛，省去端10/07 23:46
37F→: 子的干擾和花費欸！保證純淨10/07 23:46
44F推: 老前輩 一堆蛇油和相信自己之術10/08 04:56
45F→: 我只能說，比擴大機還敏感的量測儀器設備都不用這樣搞，3810/08 05:01
46F→: 平方，一堆人家裡台電電表出來都沒這麼粗啦 真的是標準10/08 05:01
47F→: 蛇油10/08 05:01
48F推: 油管上很多老外儀測power cable的結果就蛇油,用對足矣，只10/08 05:11
49F→: 能說信仰有了人耳比儀器更敏感，解析力直入雲霄10/08 05:11
50F推: 基本電學看你好像也不是很懂，負載效應在電壓與電流的關係10/08 05:18
51F→: 也不熟,開口就提38平方，你認真？你連一個線徑在固定長度10/08 05:18
52F→: 下，負載在什麼程度會掉電壓都沒概念吧10/08 05:18
71F推: 音響跳脫框架？ 你知道什麼叫聲學Acoustic嗎？ 科學的東西10/08 16:26
72F→: 被誤會玄學是因為，外在因素太多，信眾不把因素用科學的方10/08 16:26
73F→: 法納入分析，土法煉鋼直接用聽感來解釋帶過，音響要提升最10/08 16:26
74F→: 有效就是換喇叭，換環境，其他的就真的是改爽的10/08 16:26
75F→: 大廠真的的是最愛這種客人…….10/08 16:27
12F推: 推力不足是在亂講什麼，就純粹增益開太小低頻差，因為你喇10/02 09:41
13F→: 叭低頻滾落跟不上中高頻段，你拿怪物後級開一咪咪一樣低頻10/02 09:41
14F→: 出不來，擴大機推力不足跟你開的增益是兩碼子事10/02 09:41
40F推: 很轟是品質太差，一般的重低音就算廠箱爛的也是一大堆，過10/03 12:42
41F→: 度追求低頻延伸的結果10/03 12:42
44F推: 哪有不是...JBL大箱子上面的woofer可以轟到30Hz以下ㄟ10/03 17:03
45F→: 只能說不是貧民二聲道的範疇 有錢幾聲道都轟得起來10/03 17:04
66F推: 轟不轟箱體設計就天註定了，你去調音就是把失真的部分砍掉10/03 23:29
67F→: 而已，倒相式的重低音，倒相孔出來的非線性失真非～常～大10/03 23:29
68F→: ，把那部分砍掉就會乾淨，速度快，但是下潛-3dB點也提高就10/03 23:29
69F→: 會覺得量不夠，高低通的設計也有關係，設計爛的impulse re10/03 23:29
70F→: sponse和group delay數字不能看，當然也是又轟又糊10/03 23:29
73F推: 怎麼不能砍 你要最快直接高通砍下去啊10/04 00:24
76F推: 會影響,要抓平衡點10/04 01:18
80F推: 失真可以降低，看個人取捨找平衡點，我先說不要迷信廠箱，10/04 08:38
81F→: 大牌子求帳面數字好看-6dB點也是標，消費者看了也爽，下場10/04 08:38
82F→: 就是轟轟轟，十幾萬的超低音照樣是那種死德性，數據都亂標10/04 08:38
83F→: 還能期待啥10/04 08:38
84F→: 找一顆超低音把T/S參數找出來，把電路抄出來，套箱體下去10/04 08:46
85F→: 算，就知道我在講什麼，你要劇院效果轟轟轟沒差可以不計較10/04 08:46
86F→: ，要Hifi低音精準反應快速，下潛一定比較轟轟差，要Hifi10/04 08:46
87F→: 又in your face，最簡單就是大單體大容積的密閉箱，是要拿10/04 08:46
88F→: 東西換的，一般人家裡落地喇叭都不一定有地方放怎麼會擺得10/04 08:46
89F→: 下這種鬼東西東西10/04 08:46
94F推: 兩回事？ 你連模擬都沒跑過吧 =_= 我看你不太懂非線性失10/04 12:56
95F→: 真主要是在哪10/04 12:56
96F推: 高通就是要把倒相帶來的非線性失真砍掉 你說兩回事??????10/04 13:02
97F→: 你是不知道失真在哪長怎樣還是誤會高通不會設計高通10/04 13:03
98F→: 失真的主因是共震延冗? 這跟那有什麼關係? Group delay10/04 13:05
99F→: 數字漂亮和良好抑震箱體 就算是這樣 線性失真就是再那不會10/04 13:06
100F→: 不見 倒相設計就是這樣 失真就是在那邊10/04 13:07
101F→: 封閉箱 被動輻射 倒相 倒相的失真最大 這是天生的10/04 13:08
102F→: 你先去搞懂倒相怎麼去求更深的下潛和失真怎麼來的10/04 13:10
103F→: 去看看各家最好的HIFI重低音是用倒相還是另外兩種多10/04 13:12
104F推: 失真這種東西量測或是模擬一翻兩瞪眼的東西.......10/04 13:16
105F→: 模擬的條件都已經箱體最佳化在跑了，失真畫在Graph上10/04 13:16
106F→: 然後卻要說是共震延宕 =_= 我不懂10/04 13:17
107F推: 總之就這樣 上面說PEQ也可以，是說minidsp入門的跟玩具一10/04 13:20
108F→: 樣但要也要5000 600010/04 13:21
5F推: 過譽了10/01 21:23
6F→: 墊材腳架的錢不如直接拿去砸一顆重低音 真心不騙10/01 21:24
15F推: 當然不是假貨，但就低頻體驗的差異和是否滿足需求，要跟落10/02 09:48
16F→: 地箱比小書架就是不夠10/02 09:48
22F推: 所以說視需求，啊人家就是要更大量感的話，要電音蹦蹦叫，10/02 15:05
23F→: 不來一顆重低音解決不了的10/02 15:05
38F推: 基本教義派 ：低音單體？ 沒有18寸以上談什麼低頻！ 小單10/03 23:35
39F→: 體談低頻就跟隆乳的說自己奶大差不多10/03 23:35
8F推: 80dB的喇叭，功放要很大力催哦09/30 15:22
9F→: 人家1W可以到87dB，你這台要4W多才能到87dB09/30 15:23
11F推: 先說這台是低音10W 高音2個5W 合計20W09/30 16:14
12F→: 如果它是80dB@1m/20W 那這個效率爛到嚇人09/30 16:14
13F推: 差不多接近68dB@1m/1W 這種東西2022年還有在生產?09/30 16:19
14F推: 是說我也不會去買這家貼牌的東西就是了 吉他音箱頭老店09/30 16:23
22F推: 我也下了一組 廠商說中秋後的機器已修正問題重新生產 我也09/26 19:55
23F→: 試試看09/26 19:55
33F推: 我的新版A20a到手了 音量10點鐘目前沒什麼問題 BTL聽感會09/29 06:45
34F→: 差很多嗎？09/29 06:45
35F推: 我覺得20d那個電源和選單按壓式的設計很爛 這種很容易壞09/30 11:08
26F推: 橫放單體朝外靠左靠右09/29 08:55
