英國喇叭廠PMC將家用市場的喇叭升級，將現有的型號從"+"改為"i"，包括最小的書架DB1i(英鎊770)、中央聲道DB1M-Ci(英鎊425)、書架TB2i(英鎊950)、中央聲道TB2M-Ci(英鎊500)、小落地GB1i(英鎊1,275)、中央聲道CB6i(英鎊1,500)、中落地FB1i(英鎊1,850)與最大的落地OB1i(英鎊2,950)。單體與分音器都有升級，箱體也都改為全部是原木的，當然也包括背板在內。PMC的商標也改為金屬製的。高音為與挪威SEAS合作開發的Solonex soft-dome單體。中低音也更換為PMC新的單體，可承受更高的功率、更平順與更少的扭曲。分音器使用法國Solen的電容，並配合新單體重新設計。

PMC發表了MB2 XBDi，訂價英鎊17,500/對。原本的MB2 XBD專業主動式版本目前仍為Emil Berliner / Deutsche Grammophon, Berlin所採用，新的被動式版本使用與主動式版本相同的PMC手工製75mm的中音單體與兩顆12吋Radial™低音單體(ATL™ , Advanced Transmission Line)，只差在擴大機。工程師手工製的32階、24dB的分音器(32 element 24dB per octave crossover)設置在專屬的箱體中，位於喇叭後面下方。與其他i版本一樣，MB2 XBDi使用精調後的SONOLEX™半圓球高音，箱體使用更高密度的Medite®所出品的MDF。

Radial? Harbeth不再「獨家」採用這材質了嘛？:O

劉主編可要好好問問看Harbeth or PMC了...
Alan在論壇的回覆蠻快的
表示PMC的單體跟Harbeth沒關係

======================
Dear Alan,
I see the Radial is used as PMC MB2 XBDi LF drive units, is it the same with Harbeth?

Best regards,

======================
Of course not. We've been using RADIAL as a descriptive name since the early 1990s. We make our own drivers and I don't think many companies have the skills to design and manufacture their own drive units - because if they could, surely they would. In-house manufacture gives you exactly the performance you want and far more control over QC. Setting aside for a moment the superior sonic quality of Harbeth RADIAL, the RADIAL drivers we make ourselves are so incredibly consistent that there is nothing that we could buy-in that has anything like as good a QC.
Might be worth you enquiring as to what that driver material and supply source actually is. We do not make Harbeth's crowning glory available to any other company.
音響論壇劉總編將二對ATC100堆疊起來聆聽，小弟粉好奇為何沒有人將二對BB5或MB2也堆疊起來，形成類似點音源的方式使用呢？(mem)
二對MB2加起來一起使用，價格好像比一對BB5XBD便宜的樣子，這種玩法難道不會比較超值嗎？:O
BB5XBD的實力已經那麼驚人了，換成是二對BB5，那豈不是嚇嚇叫！:^)
這句話“We do not make Harbeth's crowning glory available to any other company.“ 很有意思。好像話裡有話。
MB2與BB5都有自己的低音柱，可以疊起來用，也可以分開用。我在曹永坤先生家中曾聽過BB5底下墊上低音柱的聲音，那已經是很驚人的氣勢了。引用:

兩對喇叭疊起的確是「接近」點音源的作法，但是也還不是真正的點音源設計，在增加氣勢之餘仍然多了一些「不精確度」。也許，這種「不精確度」人耳還無法分辨出來，但是仔細觀察PMC與ATC的設計，一個頻段內都不會用兩個同樣單體，這也可說是他們「不願妥協」的態度吧！
兩對MB1疊起來聽引用:
作者: martin
以前論壇一位跆拳道主筆好像就這樣聽
我是認為MB2傳輸線出口在上面
真的兩對疊起來
兩個高音單體相隔甚遠
這樣擺聲音相位不會有問題嗎??
IB2i(£8,900)、MB2i(£10,350)與BB5i(£14,950)

‧PMC/SEAS Sonolex 27mm tweeter, complete with dispersion plate
‧PMC's 7.5cm soft-dome driver, also found in the company's pro monitors
‧IB2i uses PMC's 25cm flat carbon fibre piston bass driver
‧Larger speakers have the striking Radial driver: a 31cm in the MB2i, and a 38cm in the BB5i
‧All the speakers use a newly-upgraded 32-element crossover.
‧The BB5, by the way, is designed for use with amps from 200W to 1kW!
‧As well as having PMC's familiar Advanced Transmission Line loading, the new cabinets are now made from higher-density Medite, with a staggered jointing process being used to give greater integrity and stability.
‧The speakers are available in black ash, walnut, oak or cherry wood veneers, and are priced at £8900 a pair for the IB2i, £10,350/pr for the MB2i and £14,950/pr for the BB5i.
MB2這腳架不錯看
但是好像沒有跟喇叭一起進口
在台灣好像只能買到台製品:)
pmc 在站中的用家很少是不是?
也很少看到討論,
pmc mb2i,bb5i
大家覺得是好喇叭嗎?
大家評價如何...
