Your performance car built in the United States, Germany, or Asia was designed to provide good handling with a comfortable ride.Manufacturers fit softer springs as a compromise to please the majority of their customers who commute every day over potholes, not the driver that wants to wring the maximum out of their vehicle's built-in responsiveness.For those that do want crisper, sharper handling Eibach offers the Pro-Kit Lowering Kit.It drops your ride height and boosts handling from good to great without the punishing ride that comes from kits offered by competitors.Your vehicle was built with a sophisticated suspension, so don't compromise it with a kit that causes your car to ride rough.Riding rough is for amateurs.
Dropping the ride height lowers your vehicle's center of gravity - reducing body roll and any tendencies to lean over.Then, the progressive rate of these Eibach front springs goes to work.Unlike original equipment and some low-height springs on the market, these feature a spring rate that varies as needs demand.The top of the coil is softer for more give under everyday operation when things are not pushed hard.But just as the vehicle starts to lean when more demanding conditions arise, a stiffer and stiffer rate kicks in as the springs compress.The result is less body roll for more stable handling, faster cornering speeds, and reduced nose dive that can shorten your stopping distance.All with an uncompromised, premium ride. Founded in 1949 in Germany by Heinrich Eibach, Eibach has grown from a small workshop-based manufacturer into a global leader and manufacturer of springs and related products.You'll find Eibach springs as the chosen brand in a wide variety of industries and automotive applications.From miniscule springs for incredibly small pressure valves to large industrial tension coils, Eibach's growth and success has always been attributed to a company spirit that drives them to be the best.Eibach automotive springs have been instrumental in vehicles achieving victories in NASCAR, Formula 1, ARCA, GT3, FIA World Rallye, and V8 Supercar championship racing series among others and have been used as original equipment by AMG and other respected vehicle tuners since the 1970s.Today, Eibach also has world headquarters for North America in California where they manufacture all products sold on these shores.Features:

Very good speakers
Size: Pair
The r51ms are used to compliment my klipsch rp500m speakers and a 12 inch subwoofer in a large living room. By placing the r51m speakers to the outside walls , and the rp500m speakers to the interior, closer to the amplifier, and with the subwoofer set on deep bass only at just enough volume to barely compliment the sound, the large living room is more than sufficiently covered with at least true high fi quality sound, if not true budget audiophile sound. My entire 2.1 system is all klipsch. That's how I want it.
I am using them with a high powered tube amplifier, so presence and clarity is awesome. Placement is critical. I was initially disappointed until I switched the r51ms to the spread to the outside walls position, and the rp500ms to the interior, closer to the amplifier. The difference was remarkable. The 2 different klipsch speakers, ie one a rp and the other a r series blend together perfectly with no clash whatsoever because of somewhat more refined sound on the rp500m speakers. The rp500m speakers do sound higher end , but they are supposed to, but with the speakers as outer r51m and inner rp500m, and the klipsch subwoofer at deep bass with just a touch of volume the result is sound of such quality that I can honestly say I can be content and satisfied with it. I can say my system is complete, and no further improvement, upgrades are needed. Tower speakers as primaries are not necessary because of the high quality of sound and the high sensitivity of the 4 klipsch bookshelf speakers and klipsch subwoofer. This saves me money during this rapid inflation period of time. I could easily say that what I have sounds more than good enough to be satisfied and content with without any desire to upgrade further at this point.
Shipping speed was excellent via Amazon itself, and the box and speakers arrived in handled with care and new condition.
I am not disappointed at all now that the r51m speakers are the outside speakers, spread apart from corner wall to wall to compliment the interior placements of my rp500m speakers by klipsch. Im all klipsch here and I love it. 5 stars categorically. As previously stated, I see no need for primary tower speakers, even in a large living room, and that equals high quality sound and savings of money at the same time. I recommend these speakers. They do more than just do sound quality wise.

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.
