| [#281] KEF LS50 好欣賞長長影子兄嘅專業技術派分享，從中獲益良多！Meta改善左中頻凹陷……當年第一次聽LS50感覺好奇怪，把聲好AV，一高一低被拉升顯得聲音機械化，隔離隻R100仲比較平衡，Meta的確改善左少少，LS50新款舊款都需要大power amplifier去damp住隻Uni-Q，不過一對喇叭又豈止於頻率響應曲線？個人覺得Uni-Q單元已經注定左聲音嘅格局，水能載舟亦能覆舟 |

| [#279] KEF LS50 我之前都有調整過 LS50 分音器，但係原先目標係為咗整隻喇叭要用薄身密封箱時調整曲線嚟做布幕後中置喇叭，過程係要由量度 driver 阻抗曲線、高/低 driver 入箱後嘅頻響曲線、然後用收集好嘅數據做模擬嚟修改分音器設計，之後再做測試調試....。 有興趣享受吓 DIY 嘅過程係值得鼓勵郁手試吓，但如果目標只係想修正少少中音下陷未必需要大費周章，用 FIR filter 或普通 EQ 就 OK，起碼 A/B quick test 試吓係咪自己想要嘅嘢先。  |

| [#278] KEF LS50 我之前約略比較過舊版 LS50 / 新版 LS50 meta，新版本中音下陷已經有改善，新版嘅設計係喺高音音箱內加 meta 去增強吸音，meta 嘅設計係去優化吸音，而 QRD 係 diffuser 設計嘅方法之一並唔係用嚟吸音，QRD 吸音係設計上嘅缺陷，原理完全唔同。 另外據知 LS50 meta 新版低音單體磁路設計有進一步優化，我自己試出嚟低音失真控制都有改進。 但我自己唔建議用改分音器嘅方法去修正 LS50 中音下陷，如果用 digital source 嘅話可以試吓用 FIR filter 去修正 LS50，否則雖然中音下陷有改善頻響睇落平順咗但產生不必要嘅 phase shift 問題更大。 二來改分音要先度齊 driver z-curves 有足夠數據去修正分音器設計，否則盲目去改，改出嚟嘅效果未必如理想。  |

| [#276] KEF LS50 我以前都係用Ls50,隻喇叭本身設計就係垃圾低音，出中高你聽 本身跟機會送舊棉比你封死哂佢 如果想入LS50就入新版，冇必要在買舊版 新版用咗QRD技術吸咗本來D垃圾低音 但係睇完佢咁玩，你不如試吓買對舊50後面各放一塊QRD板，可能同佢新版本效果一樣 |

| [#275] KEF LS50 師兄：我都明白有貴買貴；小弟補充下預算幾千蚊、睇番post長長影子同朋友setup、同我的想法好接近、首先講小弟用緊小型全音想玩返手上罰企幾年magnepan1.6加對低音、又想多一個口味所以諗下再加一對書架加對低音轉換吓、所以才有添加LS50的想法、訊源用minidsp shd訂咗未收貨可玩2.2！多年前玩過Tact 2.2好正面 |

| [#268] KEF LS50 #267 there are some better vibration testing apps ( if u using an android phone) those apps able give u some idea on how;s the the characteristic of the vibration frequency etc.. of your TV cabinet Suggest, do not jump to conclusion too soon by using what kind of support to your speaker on the TV cabinet there may be better product for that task after you have some idea about vibration frequency of your TV cabinet let's say already have a piece of stone...,suppose the vibration amplitude will be reduced but frequency the same..etc..or even higher... test it with those apps etc. with stone..without stone..etc.. with stone plus a little sand bag..etc.. things we do not want to add something heavy as a support but altering the vibration frequency upper..., we want to keep the vibration frequency lowerrrrrrrrrrrrr , lets say..below 10 hz, On my desk now..without stone..the frequncy is at 6.75 hz.., and on a piece of 30mm thick stone..is 15 hz.. haha, it require different tactic...if u care.. sometime u may be better off with some Spike on a piece of stone with simple and small sand bag.. etc.. never knows... until some test Haha some off topic is great haha some off topic is such ...such as below.. i shall behave haha btw, it is 2 china within a china one of them...usd 50k handbag is cheap , for that china....those people not likely to buy KEF bookshelf one of them USD 50 handbag is expensive , vs buying power from this china may be less than 1/20 of USA , 1/10 Vs Some EU for that china LS50 is too expansive ...lower end B&W may be ... this is what i feel from working 20 yrs within china,. 最後修改時間: 2020-10-06 13:21:52 |

| [#267] KEF LS50 Anyone with experience using LS50 without proper speaker stands? Am thinking of getting the new wireless ones and use them with iso acoustic stands on a TV cabinet..(with damping matt and heavy stone underneath) |

| [#266] KEF LS50 可惜room response measurement未必識用於香港，北美以DRYWALL同木為住屋建築材料，room response measurement相信大不同 歐洲會用比較多磚，近似香港環境。所以香港人比較愛歐洲製品喺聲音比較近似創作者原意。 ELAC就算死到臨頭都好清醒, 醒目改變市場方向（並無以中国市場為中心），過去幾年以北美BUDGET喇叭為中心贏得幾好成績。請ANDREW JONES喺機緣巧合，AJ在PIONEER TAD方向其實正確，可惜PIONEER走錯市場方向。 OFF TOPIC OFF TOPIC OFF TOPIC 講吓LS50，設計調音其實在香港。目標應該開拓中国市場, 1998 UNI-Q之後無新技術嘢， 今星期個MAT公佈，應該喺KEF十九幾年來第一次有新技術公佈 中国市場喺唔喺咁撚大，我唔知，我只見十個入中国，九死一傷，而成功傷個一個（例如老麥）只是美國曾經HIT過。今日老麥剩下中国市場，死有餘辜，一路好走 希望KEF貼地啲。做啲正常市場。LS50喺我少有留家數年作品，又愛又恨，又要要笠住個頭見人。不過每每記得佢任務喺器材照妖鏡, 好洗好用! ＞＞ 得閒可唔可以介紹下呢3對喇叭? 會，等DBR62開聲先。 |
