各位燒友好
有鑑於前面貼文有人品爆發的版友成功修復了X300A,也剛好我的喇叭修復失敗,才有本
文的出現
因疫情影響無法外出,想說不如來惡搞一下我那組躺在琦富1年多的X300A無線版
在詢問下我的喇叭還在,付了贖金後不久就寄回來了,其實當初內心還在猶豫要不要這麼
做,如果修不好又無法改被動就是送個大磚回來XD
過程其實都是抱著一個死馬當活馬醫的心態去嘗試,小弟本身也對這方面完全外行,單純
就是一個消磨時間的實驗
在之前苦主貼文有回覆留言過,在嘗試修復雖然能開機,但主喇叭的擴大模組故障,剩右
喇叭能正常出聲,主喇叭則變成聲音超小,也詢問過維修店家說無法修復,於是開始了被
動惡搞過程
左右更換測試後確定出問題的模組,但店家一眼看到馬上說無法修復?

既然也是半殘,修復這條路已確定GG,就來土炮改造了
我的想法是以最低成本來玩,先求有聲再來求好,其他先不管,後來在淘寶找了分頻器
X300A內部是5吋4歐的uniq單體,賣家說搭個50瓦的擴就行了

因本身剛好有台Dx7 pro,為了試喇叭臨時收了台STA-9
先簡單接線試了一下,可出聲沒問題,再來就是固定上去

剛好有背面的開口,為求改造的完整度,就訂製加工了2塊板子,喇叭線直接焊上分頻器
,裝起來完整度算是還行

因為是自己在外租屋,受限房間大小及桌面空間,只能克難擺著測試
測試設備:
PC.usb > ddc.i2s >Dx7 pro(dac模式) > STA-9

心得:
剛開聲的感覺是音場及解析比原廠擴提升不少,聲底有些STA-9的暖聲,但低頻下潛能量
感不大,也可能是受限於房間空間太小,我也怕影響到隔壁租客不敢開大聲,不然在前級
DAC模式下以STA-9去推感覺上是非常輕鬆,PC端音控在6~8就有大音量了,雖然音量不等
於音質,但在大空間上肯定會更好的
這次改造除了購買零件的等待時間,大部分零件都是從淘寶購入,花費除了分頻器及訂做
的固定板之外其他都還好,總花費約2k左右
我知道板上神人高手如雲,其實這也算一種自製喇叭,國外也很多神人自購單體自製箱體
分頻,有更專業發燒的方式,但小弟非專業人士,只是簡單土炮惡搞去玩,有聲就好,只
是讓X300A有復活的機會,當然要更好是一定能更好看要花多少錢及心力去搞了
以上為不專業土炮改造分享,供各位KEF主動苦主參考,謝謝各位
