Well, the article has nothing to do to the dynamic response of the speaker and changing impedance for a given frequency. It's merely showing the a relationship of SPL, Sensitivity, and RMS power required at 8 ohms in 'theory'. To tackle the dynamic response of the speaker that dips up to 2.8 ohms or even lower is 'amplifier' manufacturer's problem. For example, this amplifier went one time in 'safe mode' to prevent amp section from damaging while we were using 'Satellites with Sub-Woofer' in 7.1 configuration. These speakers were 4ohms and I'm pretty sure at some frequencies they were dipping below 2 ohms or even futher when I took it to -10dB. To produce that much of a sound from Klipsch RF-7 II, I don't need to dial more than -45dB. That's the point what I was eluding to with that article, showing the relationship between SPL, Sensitivity, and RMS power. While, NOT claiming that the 2808ci is a hi-end receiver, there might be a incremental benefit to a cost in upgrading to the powerful amplifier, while typically not playing loud at -10dB and beyond. Just like what 'reference_head' said, 'I would look at a sub before an amp. A sub will blow your mind compared to no sub.' But, then who knows, when the upgrade bug hits me! Cheers!

'I would look at a sub before an amp' Agree to that statement... In addition it would help freeing up RF-7 IIs from sub-woofer duty as well.

In 'theory' at 101dB sensitivity (efficiency) of Klipsch RF-7 II, it should produce 121dB SPL @100W RMS @ 3.3 feet distance from speakers and @ 200W RMS it will produce SPL of 124dB. Basically, to increase the 3dB output from 121dB to 124dB, double power (200W RMS) is required from an amplifier. I must admit that I haven't bought a SPL meter to provide an exact number in my bi-amped fronts within a 5.0 configuration for 24' x 14' x 9' room, but in reality my ears and most importantly my loving better half's ears can only take so much for so long and thus keeping everyone happy and healthy. While, allowing me to have this 'manish' speaker arrangement in a family room, I'm quite happy and pleased man in the world! The below link/reference should help one to understand what I'm saying. If I have misunderstood, then open for correction! http://www.integratedaudio.com/help/sensitivity.pdf

IMO, yes since they are very efficient speakers @ 'sensitivity' of 101dB. Enjoy! btw., many congratulations for RF-7 IIs... Pite, you have some very nice speakers but a lower end Denon is not doing your Home Theater justice...I am a Denon fan but neither your AVR 28XX or his AVR33XX is rated to drive speakers with low impedance dips that the RF-7s are reported to have, much less 2 pair of them and an RC-64. They may sound nice at low volume but if you ever raise it above 75 dB your HT will come ALIVE with more power. Yeah...I know that it's a ‘lower end’ or a ‘mid-entry level’ Denon AVR from 08's, but, it does offer the 'Bi-Amp' feature, which I'm exploiting since sometimes... Per Denon Specifications it has 'Identical quality and power for all 7 channels, 110W x 7ch (8 ohms, 20Hz - 20kHz)’. Ref: http://usa.denon.com/us/Product/Pages/Product-Detail.aspx?Catid=3d9614d1-8000-4106-ab91-8192242cab83&SubId=40b5820d-83c2-4e93-9909-60aae60e0bdd&ProductId=05671f1c-32eb-43ee-bd28-5ee4d2747493 Literature/Product Sheet (0.26 MB) (8/20/2010, Please note that there is one similar name just above it with (0.68 MB) size, but it has different information. So now, with the fronts bi-amped, truly speaking, if I/we stay within -55dB to -10dB the AVR does a nice job delivering mids/lows for a room size of 24’ x 14’ x 9’. While the receiver has no issues running -10dB and above, it's deafening loud. Not to mention that the 5.0 setup is creating enough bass for this room, it's a 'personal debate' that keeps me off from buying or adding current subwoofer also. All these said, the 'Upgrade Bug' does lead to a fever that drives me/us to audition decent/higher end amps, he he... While a new hi-end AVR or Pre-Pro is inevitable, the 2808ci is going to be there until it runs…

RC-64 II is a great center channel speaker...Haven't heard a better speaker in this price range - Enjoy it! btw., welcome to the forum...

'every time we go I am somewhat disappointed with the sound there ' I can hear/see that! [][Y]

nice find!

Yup, pretty much that's all you cad do! If those caps' electrolyte is dried, you are out of luck and either need to do restoration/re-build or get a new ones. Good Luck!

Let's hope that you get your reciver in working condition and not damaged cosmetically. Till then, fingers crossed! I noticed that, you are not having a sub-woofer. In that case, see if you can do a bi-amping (it's different than bi-wiring). In the case of bi-amping, two seperate amp channels are connected to LS and HS, with link between them MUST be removed. For this, your AVR should have a possibility to run in bi-amp configuration. btw., welcome to forum and Good Luck!

That's awesome! You may have found the jewel, Marvel! [H]

Sorry for your loss. While, it's difficult to fill the void, prayers for Casey and condolences to the Crites Family! []

In my case, I'd rather listen to chalk scraping on a blackboard (anybody left that knows what that REALLY means?) than an mp3. OTOH, an mp3 made from truly first class source material is superior to the finest 180 gram LP or SACD or 24/192 recording made by an idiot. My experience here is that perhaps 40 of the 40,000 or whatever registered here understand that it is ALL about the source. Great source material sounds comes through on anything, crappy source material gets worse the better your system is. Dave [Y]

Nice! So basically, playing with individual dB settings for R, L and C doesn't help? Interesting...

Sometimes ago, I was looking into this, and while googling, did find few links where 'audio enthusiast' were treating their room/area. They had different things in mind such as sound deadening, insulating, good sound etc. so that their system would sound good and then sound wouldn't travel beyond a desired boundry (mostly room walls, ceiling, floor). I would suggest to google and check them out and see if something is of help.

[Y] That's the way to go to solve your remote control need with a bonus of all new formats for HT setup thru new AVR.

Unless you can assign SBL/SBR to SL/SR, you will need to connect your surround speakers to SL/SR outputs on your AVR for 5.1. However, you can still place it at rear and see if you like the surround better from rear than side. Good luck in your placement...

IMO, yes since they are very efficient speakers @ 'sensitivity' of 101dB. Enjoy! btw., many congratulations for RF-7 IIs...

Yes, they are not 'car tires'! haha, funny!!!

No not at that point! But, you did mention in one of your previous post that AVR doesn't go in 'protection' mode when you are in setup mode or running it at low volume. It only happens when you increase it by 10dB... Typically, this happens when either the reciver's amplifier section is on the degrading path or a speaker wire connection issue or driving hard low sensitivity speakers at reference level...

If I remember correctly, someone on the forum have tried either RC-64 or RC-64 II with RF-7s and did like it. I tend to agree with Vital's point as well, as 'center' plays a major role in HT and RC-64 II should blend in nicely...IMO, RC-64 II is certainly a very sweet sounding and dynamic center channel speaker!

Errr what, i wouldnt say you would need to go bigger than a 12" unless you were wanting to go louder but other than that the 10-12" is probably the most natural way for a speaker and enclosure to reproduce sounds of 100hz and below. And how would you recommnd a 15" to go as high as 1khz, at least for a sub thats designed for sub frequencys ??. From what i know each driver size paired with component design has its own resonant frequency range and thats why floorstanders have mutliple sized drivers for each frequency spectrum it works for. Edit. I think im thinking too narrow. For a given price range, RF-7 II with their two 10" Cerametallic drivers and 1.75" Titanium Horn driver, I'm one very happy soul with their peformance and sweet sound. [Y]

He gets that at least once a day from me. Of course it looks like I've been playing in barbed wire from those sharp teeth. He never bears down, but plays with his mouth wide open. It's hard to avoid those sharp baby teeth, I've dremeled his claws a couple of times now, so they're not so bad. []

'Word on the street is that Klipsch does a bangup job on their own.' Absolutely! [Y]

I got this message from the seller...he seems like he wants to help. Oh my. I am very sorry. That sounds weird. Either way, let me know if Klipsch can replace/fix whatever is needed, And/Or I can call up the Klipsch distrbutor where I bought it from and have them replace/fix. Let me know, again, I'm sorry and had no idea . thx, Jon I think your best bet is to follow-up on this with the seller to fix the bezel issue if you still don't want to return it. Well I aVERY fortunate...the sellers distributor is sending be a brand new unit and even has a packing slip in the box of the new unit so I can send the defective one back.......He has earned my bussiness to say the least!!! That's awesome! I guess one can't ask more than that! Hope for the best and good luck in your exchange...

Yup! [H]
