Is it worth adding a Monolith 7 amp to my Onkyo RZ900?
M Mark M Junior Audioholic Apr 3, 2018 #3 I have Elac Unifi towers, unifi center speaker, Elac s12eq sub, 2 debut ceiling surrounds. I also have debut ceiling speakers in another zone. I may add more ceiling speakers to a 3rd zone.

M Mark M Junior Audioholic Apr 3, 2018 #5 The rz900 volume is at 60-70 during regular tv. 70-80 during movies. 70-80 during music. I don’t notice any clipping, I think. My system is in a great room. My speakers are 9.5 feet equal distance.

lovinthehd Audioholic Jedi Apr 3, 2018 #8 That's pretty dang loud most of the time! You might be an amp candidate to get a little extra headroom (keep in mind a doubling of power only nets you 3dB).

M Mark M Junior Audioholic Apr 3, 2018 #9 The unifis are low sensitivity 4ohm speakers. Sensitivity: 85 dB at 2.83 v/1m Recommended amplifier power: 40 to 140 wpc Peak power handling: 140 wpc Nominal impedance: 4 Ω; minimum 3.4 Ω

BoredSysAdmin Audioholic Slumlord Apr 3, 2018 #12 I'd ask Elac first and AJ is occasional visitor here as well. I'm not sure that throwing 200-300wpc at these is safe for their longevity. 200wpc is not going to far. your onkyo has already very capable amp section, 140wpc into 8ohm and rated (dynamic power - a bit bending rules here) upto 240w into 4 ohm two or three of these bad boys and you'll get more power and save moneys: https://www.amazon.com/QSC-GX3-300-Watt-Power-Amplifier/dp/B0018D63KO

Just because they are rated 4 ohms, it does not mean you need to throw them more power than they can handle. In this case, they specified Peak power handling: 140 wpc, so your RZ900 should have no trouble driving them to their limits. S&V bench tested the RZ900. "Into 4 ohms, the amplifier reaches 0.1% distortion at 229.1 watts and 1% distortion at 271.9 watts." Read more at https://www.soundandvision.com/content/onkyo-tx-rz900-av-receiver-review-test-bench#RxpBK5DLoc6mZiZK.99 229.1 watts average (or the technically incorrect but generated accepted term RMS) means 458.2 watts, again, the Elac can handle peak power of only 140 Watts, so you can actually blow the speakers with unclipped power by the RZ900 if you wish, without the help of a more powerful external amp.

That score system won't work for you because you already own an AVR that can provide more power than your speakers can handle. So regardless of your SPL requirement, room size etc., the speakers are the bottleneck in this case.

M Mark M Junior Audioholic Apr 3, 2018 #15 Well I guess I’m all set then. Since the monolith amp won’t change anything.
