这个东西自己做怎么样,
找个现成的设计
买两个好单元,或者自己设计一个
不过估计要参考声学的书
有人自己这样干过吗? 效果如何? 花费在5000人民币一下.

I have a speaker which says 260w.
My receiver can only deliver 100w / channel.
most receiver can deliver less than 140w.
what is the power required for Port RTi12?
I plan to get a pair of RTi12 or RTiA9. what receiver should I use?
If I want to purchase a stereo preamp, any recommendation?
Thanks guru.

又到午休时间。今天聊聊rebalancing. 很多投资股票多年的朋友都没听说过这个概念

谈rebalancing, 不得不先说asset allocation.
financial planning的一个很重要的部分就是asset allocation based on individual

take risk, 概念可大可下。不理解asset allocation, 是很难了解active management

Red Sox Owner's Fund Gets Bloodied
......
A fascinating chart on Henry's Web site shows that, thanks to recent
catastrophic losses, anyone who jumped into his main fund when it launched
in 1996 and stuck with it until today has actually done worse than they
would have in a fund that merely tracked the S&P, international stocks. Even
30-year government bonds fared better. Overall, they've done worse than a
cheap index fund.

path for your share of wealth creation (or wealth shrinkage during recession

发帖数: 1707 | 28 Yes.
Suppose you define two Runnable objects r1 and r2. They share the same
object of C. r1 calls method1 and r2 calls method2 in their run method.
Then you can use
ExecutoreService es = Executors.newSingleThreadExecutor();
es.execute(r2);
es.execute(r1);
Then it is guaranteed that r2 finishes running method2 first and r1 runs
method1 second. |

发帖数: 1133 | 38 it depends on the behavior you want
do you want the caller to be blocked in m2 and notified when m1 is done?
or do you want m2 to return to caller immediately?
both are pretty easy to implement with some thread sync approeach.
blocking is bad, usually. |

Can you design a mechanism to make sure that B is executed after A, C is
executed after B?
And the solution is using two semaphore synchronize between A&B, B&C. I

在Java里就是用wait and notifyall.
