This review is from: Polk Rti A9 Cherry High Performance Floor Standing Speakers
Pros: Good investment, Great for home theater, Great for music, Easy to drive, Very attractive, When driven properly has thundering bass, Articulate, Crisp, Detailed
Cons: A little harsh, or bright during break in.
Other Thoughts: If anyone tells you these speakers don't do music well, then maybe their expectations are worth $100,000.00
I drive my A9's with an Emotiva XPA-2, 300wpc. I can crank these things til I can't stand it, no distortion.
As they break in, these speakers really deliver the quality audio I hoped they would. Mine are towed in just past the listening point, almost 9' apart and just over 2' from the wall.
During movies, if I take my sub out and set the 9's to full, LFE can be felt in the floor and in the chest, they hold no candle to my Epik Empire but they can punch out the bass.
For music, I use them for 2ch listening only, no other speakers and no sub. The detail in the 9's are incredible. If you watch, it looks and sounds like the vocals are coming from the center channel. If I close my eyes, the detail provides an illusion of 5 speakers playing at once, the sound actually places the instruments right in front of and to the sides of you.
Yeah, I'm pretty happy with these 9's.
Just some FYI. I noticed in some reviews, that Bi-amping is attempted to bring more power to the A9's. Just to shed a little light on AVR bi-amping, you ARE NOT doubling the power to the speaker. If an AVR has a rating of, like in my case, 140wpc, that is only with two channels driven. Once you add more channels, the power rating drops per channel, even in the case with bi-amping.
Yes, you are sending more power to the speaker, but near as much as you would think, and certainly not double, which is a gross misperception, heck, even I thought that in the beginning ;)
If you able to get bench test results on your AVR, you'll see the power out put for 2ch, then 4 then 6 and then 7 etc etc. Sometimes the power per channel drops significantly.
So if you're running four channels at one time and the power rating is only 80wpc, then your speaker now has the benefit of receiving the equivalent of 160 wpc. But now throw in the rest of your set up for a 5.1 and the power drops even more.
What's the moral, AVR bi-amping is a waste unless you're just doing 2ch PERIOD. If you're doing it for H. T. then an external amp is highly recommended. That way your speaker gets dedicated power and the AVR can do it's thing without getting overloaded.
I've had only a few guys tell me, "hey, I'm doubling the pwer to my speakers by bi-amping off the AVR", then I ask them to research the bench readings on the power of their AVR and get back to me with what they've found.
Anyway, these A9's love the power. When I'm not running a sub, the three woofers are super power hungry, and with todays audio tracks, the LFE's are sucked up by the A9's so much so that my 300wpc amplifier lights up like a Christmas tree from the power usage. But at least I'm not clipping the signal. Best to be safe than sorry when driving these bad boys. I've even bridged my amps and supplied 860wpc to the A9's, did they love it? Heck yes they did. Hope you have fun with your A9's, they deserve to be treated properly!
This review is from: Thermaltake Notebook Cooler Massive 14
Pros: Runs in a USB cable, dual fans, fairly quiet, multiple speeds, LED's can be turned off, more uses than an lap top cooler, low profile
Cons: Not 100% quiet, but that's okay
Other Thoughts: A friend and fellow Home Theater enthusiast recommended this product to me. I use it in my H.T. gear rack. I was using it on an Onkyo TX-NR807 AV receiver. This thing has a tendency to get pretty warm while in use, the "lap top" cooler just sits on top of the AVR and presto, the AVR now runs very cool. The AVR measures 17" wide X 18" deep and this "cooler" sits toward the rear of the unit, over the HDMI board perfectly, and, having dual fans, the area is covered very efficiently!
If you listen very closely, you can hear it, but if you don't know it's there, you'd never guess I have a dual fan cooler doing it's job.
I've since upgraded to an Integra 70.4, I don't know if it gets warm or not, the Massive 14 has been on top of the new AVR since I've installed it's been nice and cool since day ONE!
Highly recommended, I have external power amplifiers as well, currently using small AVR fans however, I plan to upgrade to another one of these bad boys! It is efficient, quiet and I like it!
This review is from: ONKYO TX-NR807 7.2-Channel Black Home Theater Receiver
Pros: Pre-outs, Rated at 135w per 2ch, Audyssey, multiple listening modes, Ethernet port, plenty of analogue and HDMI connectivity, 7.2 availability, even more features
Cons: HDMI board failures
Other Thoughts: It may be a moot point by now for this model however, I have enjoyed my Onkyo 807 for around 5 yrs now! After 3 yrs, the HDMI board went south. Onkyo gave me an out of warranty fix, I was out of pocket only the cost of shipping one way. It's been a champ ever since. I run three amplifiers from this unit to power 5 speakers, the 807 powers the surrounds. I use my 807 daily whether it's blu rays, CD's or internet radio. For music, the 807 offers "Pure Audio" LOVE IT!!
Yes, it's true that Onkyo has had it's more than fair share of HDMI board failures, but when handled properly, Onkyo has taken care of their customers, I know of others beside myself, so my claim is accurate!!
And now, after 5 years of ownership, I'm ready to expand my theater to an 11.2, enter the Onkyo TX-NR3010, with my 807 still running strong, will retire it's H.T. duties to a 3.0 bedroom set up :) I have no interest in the new Dolby Atmos, but instead prefer the capabilities of Audyssey MultEQ XT32 offered with the 3010.
Hopefully, those with unfortunate HDMI failures will see this and ask Onkyo for a "one time out of warranty fix". This has been a great receiver, no need to let it go to waste over a very fixable scenario.
