## Questions & Answers

**Q: Any hiss heard in horns during quiet passages?**
A: This is typically on account of your integrated receiver's THD - on my Pioneer and Mcintosh (both of which have a THD of .005) the speakers were pitch black BUT when I hooked the exact same speakers up to my Rotel Integrated and separate amps (THD .3) there was always an audible hiss, it drove me NUTS - it's actually the reason I got rid of the Rotels. So even though horn tweeters are more sensitive and more likely to hiss - that is not the case with these - it's probably the stereo unit. Hope this helps.

**Q: Can these speakers be laid down sideways? I don’t have 19” space between shelves**
A: You could do that if needed i suppose but i will say if you are tight on space i would recommend looking at something a bit smaller. These are beautiful speakers but they definitely require some room, not your average bookshelf speaker by any means.

**Q: could you use two of these side by side as a center speaker to match my dual 8in  R-28F fronts ?**
A: Yes. however, the tweeter is a 90x60 degree directionality. 90degrees horizontal and 60degrees vertical. If you turn it on its side, the vertical axis become the horizontal axis. So if you watch movies alone, it may be perfect. But i find the 60degrees a bit narrow, and easy to go in and out of the directionality of it. 90 degrees has better fall off. But horn tweeters seem to be a lot more directional than other tech. YMMV

I love horn tweeters for movies. Simultaneously more nostalgic theater sound and very crystal clear on sound effects. Works well with speech too.

**Q: is this a pair (2 speakers) or just a single unit?**
A: This is a single speaker.   You would need to order 2 for a pair.

Ich kann mich den guten Bewertungen hier anschließen. Hatte vorher Teufel Ultima 20. Die waren nicht schlecht,mir fehlte aber etwas Mitte.Kaufte zu den Teufel Boxen den Klipsch R-30c Center LS.Die durchweg positiven Bewertungen und der Center von Klipsch brachten mich dazu die Klipsch Boxen zu kaufen.WOW alles klarer,präziser,mehr Druck und Dynamik. Die Klipsch machen soviel Spaß.Klare Kaufemphelung 5Sterne, aber Hallo Ergänzung : Nach ca.4 Wochen- Laufen die Klipsch jetzt alleine .kein Center mehr,keine Teufel mehr. kein Sub Einstellung 0 Db.. Für Musik ! jetzt optimal für mich .Die Klipsch gehen so tief runter, die Höhen/ MItte perfekt . Nächste Einstellung : analog / Röhrenverstärker. bin immer noch begeistert . Ich habe jetzt einen Hybrid Röhrenverstärker dran ,Dared MP-5 BT vom Klang und aussehen des Dared bin ich klangtechnisch angekommen,erhabener wamer,raumfüllender Sound, macht richtig Spaß.
