    I have klipsch rp280f , rp450 c front and klipsch rb51ii rears, i have a polk psw10 amp that really has no business being here, i have ordered an rsl speedwoofer, june 25, still waiting for delivery,  but getting ready to set it up, where should i set the crossover,  as i have read this  and didnt really get a the best option.  I love my set up, its quite loud and amazingly clear, but lacks the kick in the chest. Also i am thinking of getting a 12 inch sub, the bic pl200 for the deaper kick in the chest, i can manage another $300, but the wife is getting annoyed at my budget expansion from original plan and think this will be a good solution, but maybe i dont need it as i havent even heard the speed woofer yet. Theatre is in basement with carpet and block walls , 15 x 22 is room size

    I think the basic concept is that you look at the spec sheet for each speaker you are running. If you have high-end speakers and a high-end powered sub, you want to set ALL speakers to SMALL (manual crossover), then manually adjust the crossover for each channel pair (Front, Center, Surround, Surround Back) to the lowest possible setting that is ABOVE the low frequency response rating of the speaker on the spec sheet. For a speaker with a 52Hz response, you would set to 60, for 32hz, you would set 40, etc.  But you can play with the settings and see what sounds best in your room as well.

    As long as the manually adjusted crossover frequency is above the low-frequency response level of a given speaker, then you will have no holes or gaps in the frequency range that is being reproduced. My receiver only has 20Hz increments for manual crossover settings, so for me it is:


    Speaker Channel:                                 Frequency Response:      Crossover Setting
    FRONT L-R  RP-8060FA                       32Hz-25kHz +/- 3dB                40Hz
    CENTER  RP-504C                               50Hz-25kHz +/- 3dB                 60Hz
    SURROUND L-F  RP-600M                  44Hz-25kHz +/- 3dB                 60Hz
    SURROUND-BACK L-R RP-502S         58Hz-25kHz +/- 3dB                 60Hz

    I think this is the way; but, I am not the most knowledgeable person here, so others may refine or correct this information. I still need to understand how the Subwoofer crossover setting plays into this, as I notice a crossover setting for it, both in the receiver speaker setup, and on the back of the sub as well.

    Will a classic Harman Kardon AVR 325 drive the Klipsch Reference or Reference Premier speakers?

    Thanks to you all for your replies. Well, I found the 'deadline' for the Klipsch July Sale' to be extended. In-fact I think it's just ON all the time so plenty of time to decide. Duh... LOL

    As it turns out I went ahead and put together my own 9.1 surround set of Klipsch:

    2 x RP-8060FA Front (w/Height channel built-in)
    1 x SPL120 Sub
    2 x RP-600M (side channel)
    2 x RP-502S  (back surround)
    1 x RP-504C (front channel)

    This seemed like the current best quality for buck. The RP II's are out now, but cost twice as much, but because of this the prices on the standard Reference Premier's are now quite nicely down into the common man range. :) I like the clean look of the newest RP's too I guess.

    I realize I wont get the last 2 channels only having 7.1 on the receiver, but perhaps one day I will upgrade to a 9.1 or higher receiver, or find another way to utilize the height channels built into the RP-8060FA's, and for only $100 more per speaker, having the built-in height speakers was too good to pass up. 

    Anyway, I keep looking at the old AVR-325 spec that reads "Total Power Consumption:  890W w/7-channels driven", while other modern and supposedly more powerful receivers (like Marantz) report 100-150+W per channel, but with a strange "70% guarantee" -> "70% of rated wattage per channel, with 5 channels driven".

    So, I am look at this a wondering... wtf??? And I see so many people saying how much better the old HKs sound than the newer receivers, and how much the newer designs have their power ratings jacked-up on paper.

    Even before seeing you replies, I decided to go ahead and get this set of speakers and see how it goes. Hee... like audio exploration, into the unknown. There is what is supposed to be, what is not supposed to be, and what I might find I guess. I'll know when I get there. Hopefully I don't crash my boat into the rocks. :)

    I'll be a week now receiving the various 8 units, and then getting them from the USPS PO to my place in my Veloster, and then up the stairs. lol Then another day or two  on a weekend getting them unboxed, swapped into place, and tuned.

    Man... it's a lot of money and a lot of work. Hopefully it will be worth it. :)

    I have 10 hours left to answer this question (or I miss the July Sale!)

    Will a classic Harman Kardon AVR 325 drive the Klipsch Reference or Reference Premier speakers in 7.1 configuration? The AVR 325 is only rated at 45W per channel x 8 - but this era HK is apparently way more powerful than your average receiver rated at this power level.

    The room is 18' x 16' w/normal ceiling (8-9 foot). Would I be able to upgrade speaker to the reference series for this receiver?

    Replies are welcome as I only have a few hours left to buy.

    Thanks! - Garo
