In walls are one thing, but I'm concerned that the Heresy drivers weren't designed to work well when hung in that orientation. Now planning to use speakers purpose built to be installed in the ceiling instead. Cool marketing by Klipsch and Chipotle though! Just came in from viewing the Super Blood Wolf Moon in -3 degree temperatures. That was very cool also....and cold!! Chuck

Tim I just fell out of my chair reading that sentence. I was imagining four Klipsch Heresey's hanging from the ceiling. Whatever configuration you are going to get you are going to be having a large grand sound. Though I'm not a big fan of the Klipsch horns, I won't deny so many speakers for surround would be an experience for sure. Thanks Gar, I would have at least entertained Atmos...but with twenty foot angled cathedral ceilings I could never really pull it off. My basement does in fact have Klipsch Pro KPT-200 speakers hanging from the ceiling for height and rear surround. www.klipsch.com/products/kpt-200Basically a two way Heresy with extremely high output and a 1.5 inch titanium compression driver. Unbelievable how strong these are. I think each speaker weighs 47 lbs. Tim I just fell out of my chair reading that sentence. I was imagining four Klipsch Heresey's hanging from the ceiling.

I actually was trying to figure a way to build Heresys into the ceiling for Atmos. But I'm drawing the line there and will use Klipsch ceiling speakers instead. Clearly you boys know how to party!!

And I finally got the Klipsch RP-600m speakers to fill in the midrange like the Klipsch Heresys do. Took three things:
1. Put the speakers on stands so the woofers (not the tweeters) are at ear level 2. Leave the grills on the speakers (they're too bright without them) and 3. Use the (cough, cough) tone controls to reduce the treble by 1 dB and up the bass by 1 dB
NOW they're something to listen to!
And by positioning, I've eliminated the need for the tone controls.

Playing with the OPPO UDP-205 (Roon ready) directly into the power amps. Not too shabby... The current power amps seem to ameliorate some of the Oppo's Sabre-DAC-shrillness.

Glad you are enjoying those RP-600 and that you got them set up in a way that better suits your needs. Do you still have the Heresy Boom, or are they gone home with their owner>

The Heresy speakers are still on loan, and I have permission to keep them until my review of the Klipsch RP-600m speakers is complete. Last night, I hooked up the Heresys again, and REALLY enjoyed them. It took some adjustment of the subs to match the Heresys because the smaller speakers are less sensitive, but the sound was glorious. Don't let anyone tell you that Heresys won't image either - Sounded awesome! I have the Heresys placed closer together than the 600s, and many (most?) speakers in that position give a deep center image, but not a wide image. The Heresys (with no toe in, even) managed to do both deep and wide. I've no idea why, but I'm not looking a gift horse in the mouth. The Heresys I'm listening to are actually Generation one "HWO" models that someone has modified to use banana inputs. I'm listening with the grills on, and with the speakers up about 20 inches on top of the subs - I think garbulky has photos. Since I'm driving the speakers and subs off the balanced outputs of the Oppo UDP-205 (feeding the power amps and the subs), there is no bass management. The (sealed-box) Heresys are driven full-range, and the crossover on the subs is being used to roll-in the subs below the Heresys. The subs & Heresys are about eight feet apart with the listening distance about 11 feet. The subs and Heresys are about two feet from the wall behind them. The power amps are 140 wpc. This is giving a lovely, relaxed sound that still has significant detail and speed. If you heard these with a blindfold on, you wouldn't know that they were horn-loaded speakers. Very surprising...

This discussion of the Heresys reminds me of our dearly departed friend Chuck Elliott. I recall he was a big fan also. I'm reminded of how much we miss him!
A great weekend to all!

I have a larger (33x15x9) room and a new set of Klipsch RP-600m speakers. I also have a pair of 15" downward-firing subs. My crossover (JL Audio CR-1) is capable of discreet R/L stereo bass management. At what frequency should this pair of satellites be crossed over to the subs for stereo audio use only? I've had audio amigos advise me that I should set the crossover as closely as possible to the -3dB roll-off point of the satellites, but as I see it, this has numerous potential disadvantages: 1. The acoustic roll-off of the speakers will be added to that of the upstream electronic crossover, causing asymmetrical crossover rates between the satellites and the subs. 2. The intermodulation distortion of the satellites will be increased because of the higher woofer excursion on the satellites. 3. The single 6.5" woofers of the satellites will be stressed at high volumes in my room. I've (conversely) also had other audio amigos recommending to me that since I do have two subs, and because those subs will (initially) be located as closely as possible to the satellites, that I set the crossover to as high a frequency as possible (150 Hz. with the JL). As I see it, this does have some advantages, but also some disadvantages: On the plus side: 1. The intermodulation distortion of the satellites should be minimized because the longer excursions required for lower bass will be handled by the subs (whose larger cone area will minimize distortion for the same volume). 2. The amount of current required to run the satellites will be greatly reduced allowing the use of much lower wattage tube amplifiers if desired. 3. By judicious use of the phase knob on the sub's plate amps, I can move the subs more independently of the satellite locations. But on the minus side: 1. Having a higher crossover frequency may allow the transition from satellites to subs to become more audible. 2. At higher frequencies, acoustic localization of the subs may become more likely. 3. The downward-firing design of the subs may muffle the higher frequencies. The specific subs being used are Powersound Audio S1510DF models, a sealed-box design that has worked well in my room before. I plan to use the JL crossover with 24dB / octave slopes, rather than the more ubiquitous 12. So noting that movie soundtrack use is NOT a priority for this system, where should the crossover point be set? Thanks in advance for your help - Boomzilla

The more accurate answer is whatever measurement that gives you a smooth bass response with an even transition. In this case, it's about running some frequency sweeps and taking measurements. The room and its interaction with the speaker will give you different crossover points of varying smoothness. I know my Axiom m80's don't reach anywhere as low in your room as it does mine. So a stated -3db point isn't really accurate. If you don't want to measure, you are going to have to do it best as you can by ear.

still cant believe someone as fanatical about getting everything exact still hasnt embraced measuring...and just guesses There are so many variables - -Frequency Response of Mains -Frequency Response of Subs -Resonant Frequency of Room -Standing Wave Points in Room (which will vary with frequency content of source) -Listeners audio acuity -Positioning of furniture -Materials used-in and covering walls, floor, ceiling -Personal Taste in Music (How one "thinks it SHOULD sound" - which varies from person to person) (and several others that have minor effect, but I cannot recall them now) Calculations often work great for "guidelines" - but what sounds optimal with one recording will be less so with others For Sweet 2-Channel, one must experiment and find what works best "on the average"... (Which is where your EARS become the instrument to be trusted above all others)

Thanks, geeqner - You're right, of course. If the question were an easy one, I'd not have troubled youse guys with it! LOL I'm currently using 130 Hz. as the crossover point, but I think I'll have to slide it down a bit. The upper bass sounds too smooth when notes are in the crossover region. I'll drop the transition to 100 Hz. and see if that helps.

- SWAG = "Scientific" WAG (Start with some carefully-calculated numbers, then tweak as needed to compensate for this thing that we call "Reality"...)
I first learned about the WAG vs. SWAG for assembling competitive bids for installed Fire Alarm / Security Systems. (It's kinda' the same thing, but boogering-around with different numbers.)
