Enigma Traitors : The Struggle to Lose the Cipher WarEveryone knows the story of Enigma and secret codebreaking in the Second World War: the triumph of Bletchley Park over world class cipher technology. Except that excellence in codebreaking was nearly betrayed by incompetence in codemaking. German codebreakers were effective and Allied codes and ciphers were weak. With both sides reading each other's codes, the biggest secret of all that the codes had been broken was now at risk. Sooner or later, on

Everyone knows the story of Enigma and secret codebreaking in the Second World War: the triumph of Bletchley Park over world-class cipher technology. Except that excellence in codebreaking was nearly betrayed by incompetence in codemaking. German codebreakers were effective and Allied codes and ciphers were weak. With both sides reading each other's codes, the biggest secret of all - that the codes had been broken - was now at risk. Sooner or later, on one side or the other, the cipher failures would become known, the systems would be changed and the most valuable source of intelligence would dry up. Were it not for obstinacy, overconfidence and ostrichism. On both sides. The Germans demanded that the traitors be rooted out; the British stifled cipher questions beneath a tangle of committees. The codebreakers' contest became a struggle to lose the cipher war. From the very outset, the Enigma secret was one of treachery, betrayal and deception. This is the story of the people who fought behind the scenes for cipher security - and of the Enigma traitors.

Love Klipsh speakers. Beautiful, full, rich, clear sound. Combine with a sub for best sound. Very loud. Love these.

Great Sound
Size: Pair
Great things sometimes come in little packages. Powerhouse sound with virtually no input at all. Tight, crisp, and well-made as usual from Klipsch. If you are looking for a powerhouse monitor these are what you want.

Great starter speakers - for the right price.
Size: Pair
A good all-around pair of starter speakers if you're planning on using them as standalones. These will have zero trouble filling a small to medium sized space with rich and detailed sound at low to mid volumes. The bass is adequate for their size. They're not going to knock your socks off on more thumpy genres. I would imagine pairing them with a subwoofer would make quite the difference but for rock and some synth pop, they're pretty sweet. Plus the copper woofers look very striking without the faceplates. That said, I say these are best suited at low to mid volumes because cranked, the higher frequencies can be awfully fatiguing coming out of these speakers. I would not pay anywhere close to the $349 MSRP for these (you can probably find a pair of far superior RP-600Ms for around that price nowadays). Around $150 seems like a sweet spot for the R-51Ms, but the Sony SSCS5s and Fluance Signature bookshelfs are very comparable, if not better sounding for around the same price. Still, these will probably more than satisfactory if you're not expecting to be blown away by them. UPDATE 5/20/25: Can confirm that the subwoofer made a big difference. I was going to retire these since I replaced them with some bigger floor speakers on my main setup but I decided to try them out in place of the factory speakers on the Klipsch ProMedia 2.1 I have hooked up to my computer. Not only does the onboard amp seem to drive them okay at not-insane levels of volume - they sound really sweet paired with the 6.5-inch subwoofer. While I won't change my rating, I do highly recommend getting a sub along with these speakers.

Great speakers, rich full sound
Size: Pair
These are really great speakers. I got them to go with my husband's new record player for Christmas. These really sound fantastic. A rich range, with a nice bass that's not too much. They were easy to connect to the player. I like a rich sound better then bright (I think if it's too bright it doesn't have enough bass), and these definitely fit the bill. I got these on a black Friday deal which was even better. They are a good value for the quality.
