  1. if you do need another C7, you may want to keep an eye on www.ubid.com they still seem to be popping up there from time to time. & from there they're new w/ the full klipsch 5 yr factory warranty.

    i got another new c7 to use as a rear center from there for about $270 including shipping.

  2. the nonfiltered LFE inputs on the rp are compatiable w/ also using the gold straps or wire to connect the bottom posts (sub section) to the top posts that are connected to the fronts terminals of the receiver. so you want to leave the sub section also connected there so you don't lose any bass in between what comes out of your receiver sub out & the fronts terminals.

    i think the crossover on the bottom speaker terminals (sub section) in the rp is at 80hz. so that way you may still get some directionality in the rp sub woofers from the speaker level connections (gold straps or wire).

    the main reason to connect the LFE ins to the sub out of the jvc (you can use a Y-adapter or daisy-chain one rp to the other using LFE out to other LFE in) is for LFE. that's the .1 channel in 5.1 material. should be more dynamic that way.

    you should probably then set the fronts in the jvc to large. you could even set it if possible so it sends only LFE to its sub out & thru the rca interconnects to the LFE ins of the rp. may not be much audible dif but you can experiment w/ different settings in the jvc & w/ dif source material to hear what sounds best.

    but since the the low bass is filtered around 80hz in the rps & also filtered at 80hz thru the jvc sub out, you won't be getting much if any directional bass from the rp sub sections anyway.

  3. no you should be fine. just was checking to see whether you should use the sub out of the jvc for lfe in HT or not. i think you should - that is also connect the jvc sub out to the LFE ins of the rp. & use that along w/ the fronts terminals connected to the rp top posts along w/ the gold straps or wire running from those to the rp bottom posts. you should get good LFE & bass that way.

    cut & paste this thread or do a search for rp-3 in this section. much rp info there.


  4. congrats. they should give you pretty good bass even in that larger room. make sure you experiment some w/ their placement as that & the room can make a big dif in results.

    are you using just these 2 rp just for stereo music listening, or are they part of a 5.1 system also for HT?

  5. mike, i have time warner digital w/ a scientific atlanta 2100 box & digital output hooked to a digital input of my b&k ref 30 pre/pro.

    the b&k displays the bitstream its receiving & its showing either "ac-3 2.0" or "ac-3 5.1" depending on the broadcast for all my digital channels. when i go to an analog channel it of course shows analog.

    so i think this verifies that it is a digital bitstream, unless time warner has figured out a way to trick my independent pre/pro. but the b&k shows the same "ac-3" info when i play a dvd in dolby digital.

    seems to me the problem was your box wasn't digital. otherwise there should be no dif between cable & sat systems as far as passing an ac-3 bitstream.

  6. cd, excellent. & sounds like you found the peak in the room. when you get that sub you should have some pretty strong bass there. be sure to put the sub in your listening position & crawl around the room to find where the bass sounds strongest/best. probably over in or near a front corner.

  7. "the mass of a body determines the extent of attraction (i.e. the strength of the

    gravitational field)."

    john, that depends what you mean by "extent of attraction". the mass of a body doesn't determine acceleration. in a vacuum anyway that's a constant. it does determine velocity, momentum & force though as far as i know. but that's as far as i'm going. 9.gif

    btw, how is something correlated indirectly? did you mean inversely?

  8. d, assuming you have a receiver w/ a sub out to where you'll be connecting the sw, turn the crossover all the way up to 120hz or highest. your receiver will do the filtering & you don't want the sw's crossover cutting any lfe.

    & probably will sound overall best setting all the speaks to small & sending the low bass only to the sub.

    as for level, i'd set that sub to flat (0db) in the receiver & adjust the sw's output to where it blends or sounds best to you, or best of all use a sound meter to calibrate the sub level & all speaker levels w/ the test tones from your receiver or a test dvd.

    as for phase, sit in the listening position & have a helper switch it back/forth while listening to some bassy cd. leave it where the bass has the most impact &/or sounds best to you. as many don't, you may not hear any dif in the phase settings. if so, just put on 0 (in phase w/ your speakers).

  9. man, physics revisited. i still can't relate to that, in a vacuum, a feather has the same acceleration as a brick. i think that vacuum thing is the key. so iow, acceleration is just a gravitational pull constant. here on earth that's 9.8m/sec squared or 32 ft/sec squared.

    how did i do? 9.gif

  10. from what i've seen logic 7, dts: neo, & DPL II all do the same significant thing: they take 2.0 encoded material & put out 2 full-range surround "channels". these "channels" are not discrete, but one of the above may make them sound more discrete & hence better than the others. i wouldn't think there should be a big audible dif between 'em, but haven't had the chance to eartest any of them here yet. 15.gif

    but all 3 offer a big improvement over 2.0 material decoded in prologic I - that is where a mono surround "channel" is sent to the surround speaks & its not full-range to boot.

  11. thx also has post-processing formats which can can be done after the decoding, whether dolby or dts. though they were developed w/ dolby in mind.

    if thx has changed their rear surround, speaker type opinion, then its because of their new "advanced steering" capability in ultra 2.

    that's just a reference. thx has always advised to have 2 rear surround speaks, & now apparently even more so w/ ultra 2 & this "advanced steering" (Bobg mentioned something about it in a previous thread).

    but I hope you can tell I'm in no hurry to run out & get a 2nd rear surround or change the speaker type because of what thx says to do. 16.gif

    you also have to keep dts in mind. they use a 6.1 speaker set-up & imho their 6.1 discrete makes a strong case for a direct speak in the rear surround (fly-over effects).

    so obviously w/ all the variables there's no set answer except using your ears & tastes. demo w/ all your various material at home. 2.gif

  12. a tech at b&k told me wrapping aluminum foil around the speaker cable can work on rfi too. still need to try that myself. will try wrapping the foil on the cable near the amp to start.

    thing is i only hear the rfi from the rear speaks w/ the long monster Z cable runs when the system is turned off. once the system is on it takes out or overcomes the rfi. so no real biggy here.

  13. moon, you should be able to relate. dsp=digital signal processor. i don't know as much as you on computers but i'd think of the dsp as the cpu. the algorithms for bass management & other processing functions are like its own little operating system.

    iow, since its in the digital domain, the dsp is programmed by the makers on how to handle all those 1s & 0s. some like your HK allow adjustability of the crossover program in the dsp.

  14. moon, depends on the mode & what your dsp does or doesn't do w/ it. if you ever play 2.0 channel material (like a regular pcm music cd) & get sub output thru the sub out, then that means your dsp is creating it in that certain mode.

    if you play this 2-channel source & get no sub output, then that mode is mostly or completely bypassing the dsp & you get output only from the 2 front speakers. some receivers call this mode "direct", some call it "stereo" - depends on the maker.

    if you play 5.1 channel material the dsp isn't creating the LFE/.1 channel. the .1 channel is already there in the material. so if you put a 5.1 disc on a "direct" type mode that bypasses the dsp then you can still get whatever sub output from that .1/LFE channel, as well as full range from all the other channels.

    iow, the bass management is done in the dsp. but most all receivers have some mode that bypasses the dsp & plays the material just as its decoded from the source w/ no further bass mgmt or processing.

  15. "Christmas Wrapping" by The Waitresses (why do i have a feeling Clu likes that one? 9.gif)

    also wonder if the "jingle bells" by the barking dogs is out in dts w/ a bigger dog for the LFE channel??? 6.gif

  16. yes it depends what the stereo mode does. if it doesn't create sub output from the sub out for 2-channel material, then its all moot & the processor will ignore the large/small setting & play just the fronts full-range.

    if you play something w/ the LFE channel in whatever mode you'll get that LFE output from the sub out/sub because the processor doesn't create or redirect your LFE. its in the material.

  17. jr, thanks for the interest. but that's another great thing about b&k - the upgradibility. i'll probably go that route when i find out what b&k is offering for the upgrade & the cost (probably 500-$1000).

    sounds like a lot of b&k dealers are offering the 30 now for $1500 or so. doubt a used one would be worth much more than $1K. if you look at the 30 now + the cost of upgrade, its pretty much the same price as a new reference 50 at $2500. so it would make sense to get the 50 unless you could do w/o the new formats like DPL II, dts es & neo, & the new 192/24 dacs, balanced connectors & such.

    if someone offered me $1500 for the ref 30 i'd take that & get the 50, but anything less would make it better for me to keep the 30 & get the upgrade (as long as its not over $1k).
