  1. Not at all. The sensitivity doesn't diminish with positive changes in EQ, rather it's headroom (ie, desired playback level subtracted from in-room freq response minus any boosted EQ plus total power handling all expressed in dB). The loss is proportional. For example a +3 dB boost in EQ yields a 3 dB reduction in headroom. Where the K402 is concerned in the home environment, this is typically not an issue in terms of capability. The K402 requires EQ for the typical Jubilee application because it behaves naturally as a low pass filter when driven above ~6 kHz.
  2. IOW, don't melt them. Like say, cranking the piss out of the volume knob looking for bass instead of using an EQ or a proper sub. New gaskets from Bob; to seal the fronts. Double check the seal on the backs. The diaphragms will last practically forever. Lastly, the horn math says don't expect big miracles from changing just the drivers. That being said, A-55G is one helluva nice unit.
  3. Want your stereo to sound extra juicy for little to no effort?? ...and not involving alcohol...cough cough Learned this one from watching the tube folks, yet found out it has not so much to do with the electronics, but rather more so the improvement in driver compliance proportional to duty cycle. Simply leave the system fired up playing the radio (or streaming) at very low-level all day long. BAM... extra smooth and wide by the end of the day when you go to turn it up. Particularly noticeable with horns.
  4. FWIW, all this talk about the purportedly "superior" dual phase-plug K55V.....it's also worth mentioning the K55M is a direct descendant of the design. The only reason Klipsch stopped installing them is because the supply was exhausted after EV quit manufacturing them.
  5. There's more to bi-amping in this case (Pioneer w/ MCACC). With the LF and HF split, the DSP is free to adjust delay to compensate for splitting of the filter network (ie. removing the jumpers). You paid for it, so I'd say use it. You'll hear the difference after you re-run MCACC.
  6. Yup. Possibly even higher depending on how the room is interacting at the listening position, but you can check that with your SPL Meter when you get that. When you start adding subs (whatever flavor you end up going with), sensitivity will eventually increase to the point of having to really dial down their filters in order to keep them from walking all over (ie. interfering with) the KG. Don't be surprised if you end up running the subs low-passed between 30-60 Hz and the KG high passed between 90-150 Hz. Something worth experimenting with even now. Might unlock some untapped potential there before spending anything. No worries there. You're welcome.
  7. As this is the single biggest factor in how any future audio expense is going to perform, you may want to make this decision VERY carefully. 15 foot ceiling height if at all possible. These two are mutually exclusive. It's not because of the speakers per say, but rather the electronics and other equipment involved to pull it off. As distortion goes down, the ear's tolerance for SPL goes up. We can handle a fair a bit of clean sound (80dB SPL in the mid range and 110 dB SPL in the bass is not unreasonable), and it takes the right gear and room to keep things able to play that "physical". Sure those KG's will go loud, but they need to be high passed to do that. Which places a tall order on that sub. The limiting factor in all this. High pass the KG to increase their power handling, at the same double or quadruple your sub count to pull as much program power out of the Onkyo, putting into the plate amps instead.
  8. It was an invitation. The thread view count doesn't lie. People are genuinely curious, regardless of the outcome.
  9. A request from the other half: "image stabilization, please." Seriously. She was interested in watching, but couldn't finish the videos because it was too hard on her eyes over the big screen. I'd recommend bumping up the FPS rate on your cameras or in your renderer, even if that requires trading-off some resolution.
  10. The above A/B suggests how each approach works out in-practice. It's not like either system is simply cobbled together, nor recorded too poorly.
  11. Courtesy of another YouTube audio enthusiast, we can finally present these two videos (about the first minute of each) that afford some degree of comparison between an all-horn Klipsch Heritage based system and a Bose Acoustimass 10, both in a 5.1 arrangement. Not a perfect scenario, but still close enough to draw some general conclusions. The blu-ray source and particular scene are the same. The amps are very similar (both Pioneer D3). Yet, my sub is not adjusted ideally and my MCACC time window, at the time of recording, was a little on the hot side. On their video the amp is set to THX Cinema, which it shouldn't be, the recorded audio is compressed somewhat (from a cell phone or the like) and the room acoustics....well, you can get a great idea what a hardwood floor will do to the sound in that regard. There's lots to discuss here so take a listen to both and fire away.

    Great football none the less. Professional aside from that one move. Some slop by both teams, but each owned it where it counted. Minimal flags. Dak has some serious potential there. Hat's off to both kickers...wow!! Anyone else notice the great sound quality in the broadcast? Dallas stadium is outfitted with all Electrovoice, and it came through in spades over my system.....big bass and all.
  13. 1. Go on ebay, buy up a pile of old Bose "cubies" or Anthony Gallo-types and pepper the ceiling with them. 2. Spend a fortune on trying to wire them all up...cosmetically if possible. On a serious note... There is no such thing as "Best" where Dolbly Atmos is concerned. The real magic lies in its high bandwidth, object-orientated signal encoding and processing. Not littering a room with as many speakers as possible.
  14. Big +1 there. I totally agree. Prior to 2005, the traditional arguments in this regard tended towards holding water. Since then however, things have gotten murky....and recently even more so. Blanket statements can no longer apply to a product where combinations of on-board DSP, sophisticated noise shaping, and novel amplifier topologies are involved.
  15. Regardless of your phone volume setting...this is going to be a given, as almost everything on the market is less efficient than the La Scala or the like. They'll spoil ya' like that. For your zone 2 issues, I second the DAC suggestion that was already mentioned. No ideas on the wiring though. As far as placement, it'll be all about putting the sound on target (ie. keeping it out of the neighbor's chili). Tucked up in the corners to maximize bass output, angled in and down 45 to cover the entire patio (above the flower pot and above the traditional door if there's room up there). Another option is to place the pair above and directly flanking the hot tub as that's the greatest source of noise (unless it has its own stereo). Although it's tempting to believe you might need to cover the entire back yard with audio. In reality you'll really be better off keeping an area "with sound" and an area with "little to no sound".
  16. Been using the following: -Deltron banana plugs. They make many types, but I purchased the basic nickel-plated kind with the crimp/solder joint (#579-0500). -Monoprice 14AWG 4 wire CL2 for anything bi-amped. -Sub cable is a mix of Monoprice, RG6 coax from CableWholesale, and 12 ga. from HD. I'll leave it to anyone else to debate whether this constitutes "the best". However, I will say without a doubt that for this particular system, it constitutes "enough".
  17. Bill, PM sent. I reviewed the manual for the XR70, and its bi-amp/bi-wire is only a 2 ch feature. Any multi-channel input and the amps swap back. Also, the xr70 differs from the xr57 in that the latter has MF/HF balance and delay adjustment available when in bi-amp mode. Probably had you wondering what I was talking about.
  18. With the XR you should experiment with tweaking the delay setting now. My experience was similar to yours, a little louder right off the bat...but with the addition of improved detail in the crossover region and a significant improvement in stereo width / depth. Been running my system bi-amped the same way through my Pioneer SC-87 since last May. It has a setting by where I can run the front three (L,C,R) channels bi-amped...using up all the spare amplifiers same as the XR.
  19. The real deal and Danny Elfman like you've never heard him.
  20. Just not keen on the romantic view of that era, nor that only a handful of people were somehow privy to what constituted off-the-shelf automobile performance of the same. Many of the famous names were simply blessed with more capital/access/notoriety at a particular time. Tweaking IC engines has been going on since their inception. Nothing special about years past, nor what's coming down the pipeline so long as it has a piston and a crank. It's all well within the box.
  21. Aside from the usual suspects upstream of the speakers themselves, how about blown tweeters?
