Title: Loud and clear!
Review: These speakers are surprisingly good for the money. I'm not a loud bass nut, so if you are, these might only be an option if you have a good subwoofer to go with them. The 5 1/4" woofers are adequate for me. The titanium tweeters are really good, and the overall sound is engaging and not fatiguing. Crisp and clear highs are what makes these stand out

Title: bang for the buck!
Review: Be aware--I'm a senior with declining high-frequency hearing. Those of you with young golden ears may have a different opinion.I have been using mid-priced B&W home theater speakers, and a Polk subwoofer, along with a ~$1000 Denon AV network receiver. The B&Ws are smooth with good dispersion but lack punch, to the point of sounding muffled. The Klipsches were purchased to use as an add-on front speaker pair ('Front A+B' configuration) in the hopes of rectifying these deficiencies.And did they ever. Upper midrange to highs on my system now have much better punch, and clarity, than before. The base is much tighter as well as more powerful. Purists may blanch, but to my aged ears the Klipsch/B&W combo sounds better than either set alone. But if I had to make do with just one, I would jettison the B&W and keep the Klipsch--even though the B&Ws cost at least 3x as much.Decades and decades ago I owned a pair of original Klipschorns. They were fantastically efficient but somewhat disappointing tonewise (e.g., strings just didn't really sound like strings). These new Klipsch bookshelf speakers are also pretty efficient (tho nothing like those original Horns) and much more to my liking in terms of tone.For the price, I think they're utterly amazing. Tight, punchy, not shrill, not tiring. Not the world's most luxurious finish or stunning cabinet, but then at this price what you're paying goes completely into the sound. (And I personally think the copper woofers look pretty cool, and I leave the grillcloths off.) Thanks to them, I look forward to one more golden era of musical listening before my hearing fades completely. I highly recommend them.

Title: Excellent product for the price I paid
Review: This is my first time purchasing the Klipsch speakers. I hookup them with my old Sony STR-D915 amplifier. The performance was very good, as expected.The speakers produce excellent sound quality: clear, crisp, and decent deep bass.They are more efficiency than my other pair of same-size speakers.This highly efficient design could improve AMP work in linear range, to avoid saturation cause AMP output distortion.Exterior: attractive spun cooper woofer color, beautiful front view, solid and refined speaker box.Interior: Sound-absorbing material was placed. The LC crossover is what I want; all components are high grade.Tweeter: deliver High-frequency fidelity sound. Since it is horn type design, sound direction is focus at the front. If more distance is needed, the high-frequency sound will not degrade too fast, but when they are positioned sideways, sound detail will lose quickly.Woofer: for 5.25 inch, produces strong bass, and sound is loud and clear, good enough for most music and singing. However, if I want to build a home movie theater system, I still need a subwoofer.

Title: Klipsch... I always loved the brand
Review: I bought these beauties soley because I always loved the brand. I just connected them to my system, and oh my gosh, they are perfect. I've been an audiophile for 70 years, and an electrical engineer for most of that time too. I built my first set of custom designed 12" acoustical maze speakers -Years before there ever was Bose. These speakers sound incredible...Another reviewer gave bad reviews because his perceived quality of the speakers. I don't know what planet he's from, I'm impressed with these speakers 😀.BTW, Klipsch is an American company... The speakers were built in Japan but that's great... And designed in America.💕

Title: they sound good for the most part
Review: At low and mid volume they sound wonderful but over half way they get echo sounding. For the price I'm pleased.

Review: オーディオ初心者です。たまたまKlipsch社ＳＰの記事を読んで本品を購入しました（アンプはmaranzu Ｍ－ＣＲ６１２）今までのＳＰとはまるで別物。聴こえなかった楽器の音が聴こえてきました。（あくまで初心者の感想ですが）オーディオ上級者のご意見をぜひお伺いしたくよろしくお願いします。

Review: Habe mir diese Lautsprecher für meine Heimkino Anlage als Frontlautsprecher gekauft,da ich nicht so viel Platz habe. Man merkt überhaupt keinen Unterschied zu großen Standlautsprechern. Die habe echt eine beachtliche Leistung. Man muss die Boxen aber ein paar Std. einhören. Dann entfalten sie erst Ihre volle Leistung. Würde die Boxen jedem empfehlen. Klare Kaufempfehlung.

Review: Ho preso queste casse da affiancare al centrale Klipsch RC 52 e devo dire che il rapporto qualità/prezzo è veramente ottimo. Suono potente e preciso, qualità dei materiali eccellente, finiture curatissime (la griglia a bassa diffrazione fissata magneticamente è una vera chicca). Per motivi di spazio non ho potuto prendere diffusori da pavimento ma questi si sono rivelati comunque una soluzione eccellente. Consigliati.
