The rear ports are different in that picture... my black ones have two round rear ports... did that bring any sonic change? the binding post setup also looks different... why is that?

first try to get them to their full bass potential which will definitely satisfy you... tower speakers might not be able to provide as much sub bass as subwoofers but they can certainly provide enough bass to thump the chest. Maybe the amp is just not driving them to their potential and may not be able to handle any impedance dips these speakers have.

I don't think crossover frequency has anything to do with headroom. The capability of your mains decide what frequency you should crossover at. If you mains are capable then 80hz should be the max crossover value. I use 80hz as my rf7iis supposedly have an impedance dip at around 70hz.

The rf7iis have plenty of bass that you feel rather than hear due to their high being a bit over powering... Due to their height it hits the gut and the chest while with a subwoofer you feel it in the legs.

rythmik is also very good... i would go for something with the most output though

I am enjoying rf 7iis for the last couple of months in a 2.1 system for now with a marantz 6010 and an anthem mca 20... very big sound, with both movies and music...

had a chance to listen to hd800S yet? i have heard that it has been tamed in the highs slights with slightly more extension in bass and the overall effect of slightly lesser resolution/detail...

................................................

i have a rb81ii with a dimple, and i don't remember hearing any difference in sound before and after that dimple happened...

i recently got rf7iis and they don't sound too bright to me, although there there are not many reflective surfaces in my room...

nah i just wanted to ask what is the definition of it....

Every time I see your username, this scene replays in my mind. i am a sci fi fan and my username and avatar is basically from stargate universe series... the universe exploration ship aka destiny... great movie though and great scene and can anyone tell me what is voltage trigger on these avrs? trying to find pre out voltage mostly led to this subject...

is there a list on a site of some kind where i can find out about the output voltages for different processors and receivers? i find tv response times and input delays everywhere, but this stuff is harder to find...

this is exactly what i am thinking. I want that extra headroom which i will have due to higher pre out voltage as the amp can go to 450W to 4 ohms also. Bottom end is the main reason i am not going with a receiver even as good as denon 4520 which can give those 160W to the channels i want to drive. An external amp would be much much better with impedance dips. I have some budget flexibility which is why i am trying to get better parts right now. I am not sure about how good a receiver would handle the impedance dips below 4 ohms, as i will push them for bass. I don't have a proper home theater room right now but i want to buy the equipment first and then build a room around it. Complicating this is that the distance from the speakers can make them drop quite a bit. The difference between 3 feet and 12 feet can cut what you actually hear by about 12 decibels. http://www.globalrph.com/master_speaker.htm i will only be 2 meters away though... i like the "in your face" blown away effect...

Ok....let's see.... RF-7ii have a 101db sensitivity. Double the power = a 3db gain in volume 1 watt = 101db 2 watt = 104db 4 watt = 107db 8 watt = 110db 16 watt = 113db 32 watt = 116db 64 watt = 119db 128 watt = 121 Looks like you will be able to enjoy about 8 seconds of that amp cranked wide open before you lose your hearing. I somehow "think" that Adcom would power your RF-7ii's just fine. Keep in mind, a quality power amp will have a much easier time driving a set of speakers, especially when you get above 5 speakers. With a receiver, as you ad more speakers, you get less power from your amp. With power amps, you have the same watts / ch even when adding more speakers. Yes...but you are wise in doing as much research as you can. Then and only then will you be able to make the best decision for you and for your setup. I wouldn't say it's for no reason at all. Truth is....do any of us "need" an amp? No. Are there benefits of adding an external power amp? Absolutely. Are they night and day difference from your receiver? No. Is this all confusing? Yes. i know that i won't be able to ever hear that loud... though some people say that the rf 7ii is not as efficient as klipsch labels them... i am actually only concerned about the bottom end, which ain't no concern with a separate amp but there is that itch that i should at least have the full capability under the belt, even though i may only crank it up full once in my lifetime... it is not actually research, i just am reading up before i have to buy them, as i still am about a week away from getting the money ... and why don't the avr/ avp makers tell these things in their specs. I have been trying to find the pre out voltages for the rca outputs of these two yamaha and marantz processors on their site and other forums but there are no proper figures... ah, i just don't want that extra 140 watt capability going to waste even though that will be less than 3db difference...

not that i need a lot of power the headroom would be lost won't it? e.g using this article http://www.audioholics.com/audio-amplifier/amplifier-voltage-gain i concluded(correctly hopefully) that the amp adcom gfa 7805,rated at 300w into 8ohms per channel and 29.6db gain with 1.61vrms input sensitivity, would only give me about 164W into 8ohms max when feeded with 1.2v rms input.... if so then spending for an external amp might be a waste considering that is pretty close to what a receiver like denon 4520(according to soundandvision.com)... so this is worrying isn't it? spending twice the money for really no reason at all? confused

researching more and more gets a little confusing at times... i didn't know of an issue before that i think i must understand before investing into the equipment that i want to buy... the issue i am wondering about is that with pre outs you need adequate output voltage to the amplifier to get the full potential of the amplifier... e.g the gfa 7805 has input sensitivity of about 1.61Vrms and 29.6db gain etc... so does that mean the the pre should have an output of 1.61vrms as well for full potential? i have heard, or rather read, that normal avrs have very low output like 1vrms... so a dedicated pre pro like the marantz av7702 or the yamaha cx a5100 a better choice or only cheap avrs have this much low output voltage? if i rather use a marantz sr6009 for a pre pro, is that good enough(don't know its output figures on preouts)? this is confusing me... what preout voltage would i need and ofcourse how?

Probably a good solution. Maybe that but usually flagship or near flagship pre/pros use better parts(DACs, analog section, lower noise floor, etc.) than mid level AVR's with preouts. Some mfr's flagship pre/pros have the same guts(minus amps) as their flagship AVR's. Bill as i see marantz has 7702 which is about the same price as their flagship avr sr7010... so they would have similar internals? then wouldn't that make the avr as better option? even if you don't use the amps? or the dac would perform better in a preamp due to lower noise floor equaling more detail in sound? my audio knowledge is limited to mostly headphone audiophile world, and all my assumptions are based on that... an external dac is better due to lesser noise etc...

Just to clarify, if you buy a preamp, you will also need to purchase an amp to power the speakers. the adcom amp gfa 7805 should do the trick, i think... the reason for the pre amp without amps is to save power(assumption only)... otherwise i think almost every avr has pre outs now...

what is the price of the a31 anyways? i don't really know... but the speakers won't cost me that cheap(i will be buying them at full price as my country won't have discounts for them). rf7iis and 64iis would cost me more than about 4.5k in us dollars. I don't think a31 is that pricey(kinda like 3k$ maybe?)... anyways, i am not thinking of getting them. I am more interesting in knowing about the preamp selection right now... a pure preamp might do the trick, without any amplifiers... is there much difference in these brands when it comes to sound? and for that matter would a flagship matter much?

bump... any advice?

Okay, i now need some advice about the components that i have decided to buy(hopefully within a couple of weeks). I am hoping to find a parasound a31, which may or may not be available. What is a good avr that i can use as a pre amp? If i am using an external amp then i don't really need a flagship model, do i? e.g if i get a marantz sr6009 rather than an sr7009? and which avr will have the best dac quality if i use it as a pre amp? denon/onkyo/yamaha/marantz/pioneer and many others are there but i have the impression that the marantz will have a smoother/warmer sound which might pair well with the klipsch speakers. I don't really know about the sound signatures of these different avrs or which are higher in quality/durability etc. Also i can get a brand new adcom gfa 7805 amplifier, if i cannot find a halo a31 in my country. Adcom's amp has 300 watts per channel into 8 ohms and is five channel too. It is also much cheaper than parasound amps. Will there be much difference in quality in those 2? i have never seen a bad review of parasound though...

i meant entry level hi fi... not mid fi... you can say that it is the cheapest headphone in the hi fi category... anyways, the hd800 has more bass in its later models, as far as i have heard... it was thinner in bass but later the bass level was increased in the more recent batches...

hd800 are twice the price and in another league... he500 is an entry "hifi" headphone with a very pleasing sound and the hd800 are one of the best when it comes to the strengths that you mentioned.... i am also thinking of buying it
