Thanks for the tips Boom! But my wife might kill me!... As an architect friend once said: "Repeat after me - Form follows function - form follows function - form follows function!" Being married I can attest to this, "nagg'n follows ill form"!

After Dirac Live 3 via Minidsp I went back to Onkyo's room correction and ran it to see what would happen. Onkyo's room correction did recommend very similar crossover points to what's been implemented through the Minidsp [no surprise, it's probably detecting the implemented crossovers working]. It's the distance which is interestingly now set at 29-30 feet in the Onkyo after running Onkyo's room correction w/ the Minidsp in the audio chain..... regardless the fidelity has improved in the most breathtaking way. The actual soundstage is 9 ft in front of the couch. What's going on? Is that really the delay the Minidsp adds to the audio chain?
I've heard that Dirac Live doesn't totally smooth the dips ...... dunno as I can't see the frequency response after running Dirac Live until this weekend through Rew. I mean this is pretty night and day for running "After" Dirac Live 3.
W/ the help of MegashOn I'm looking forward to implementing REW and MSO to find out exactly what is happening!
Couldn't resist snapping a clip of my buddy Asher listening to music ...... and man I need sit center of the couch more often!

Insane 146.8 DB by Nine 18" subwoofers. What the reviewer says is true based on my experience when demoing over 140db. Ya can't tell why things are blurred whether the objects around ya are shaking or your eye balls in their sockets are shaking. Michael aka Youthman is a buddy of mine from years on the Klipsch forum. His YouTube channel is always fun, and he has been reviewing quite a bit of gear recently. He was a youth minister for years, and an overall amazing man with a beautiful family. Happy to hear your little buddy made it through everything alright too...can't believe I missed this thread. Enjoying your journey! Tim

Tim Thank you very much Tim for chiming in and offering a little about the wonderful character of Youthman. One might go far in following/emphasizing the first verses of Psalm 1 or what I remember from George Washington's 56th rule of Civility, "Associate yourself with Men of good Quality if you Esteem your own Reputation; for 'is better to be alone than in bad Company." Hope to you see round more often and have a pleasant evening!

Even short term exposure can cause permanent damage - Loudest recommended exposure WITH hearing protection 140dB! Why would anyone want a system that can generate 147dB's in a home theater room in the first place? Unlimited narcissism or just plain stupidity? I actually doubt the 147dB claim as with some exaggeration. However, if it is in fact true, he is going to ruin a lot of hearing in himself and anyone undergoing this 147dB demo. If he might actually demand that all in the room do in fact wear high quality ear protection then this whole setup is a waste, except for bragging rights over too many beers. Sorry to come off as so critical. I'm 76 and my hearing is exceptional. I always take a spl meter to any indoor or outdoor concert. I have at times had to ask them to lower the volume. If they refuse I immediately leave. I'm sure there are many speakers designed for auditoriums, stadiums, etc that put out 145+ dB's but only very near the speaker and no where near this level at the seating area. In this review the word nonsense applies IMO.

I used to own several car audio shops and worked with a lot of dbSPL competition guys who would love to hit 147db.

The frequency in which 147db is achieved is what's exciting ........

I used to own several car audio shops and worked with a lot of dbSPL competition guys who would love to hit 147db. Right on! 147 spl is nothing to laugh about except maybe when compared to 160+ db: And DYohn, curious, what's your view on the technology of car audio vs home audio? I mean, during my install days I got to see some pretty crazy equipment. For example, it was Richard Clark w/ his Grand National Buick that had an active subwoofer enclosure which adjusted volume and port length depending on the "upcoming" frequency being tracked by a DSP in the early 1990s. The enclosure used a servo actuator like a piston to move an interior wall of the enclosure to reduce or expand the volume much like the cylinder/piston in a combustion engine. Coupled w/ a variable port acting like a valve........ I thought his setup was genius. I haven't seen that kinda technology in home audio. The limited space of the cab of cars kept pushing subwoofer technology even in utilizing "membranes" instead of enclosures to trap the rear waves of a sub replacing enclosures altogether. I remember at that time being amazed bout some of the installers talent in designing waveguides of differing lengths all to time align to a main listening position that was offset etc. There's quite a bit of talent and technology in car audio!

Spaghetti! Meh, could be worse, this is only a 3.2 channel system. Had to get back behind the entertainment stand today to switch around some of the inputs and outputs from the Onkyo AV to Minidsp. I had used Onkyo's dual subwoofer outputs to two channels input into the Minidsp giving each a single independent subwoofer channel. Reading the MSO [multi subwoofer optimization] helpguide it recommends only utilizing one subwoofer out from the AV to the Minidsp and then splitting that channel to both subwoofers w/in the Minidsp for sub optimization. Minidsp DDRC88A w/ Bass Management's "routing tab" seen below, one sub input is seen split to two subwoofers assigning a Dirac channel each number 7 and 8. I'm also utilizing MiniDSP's wifi which allows me to use my PC to connect to the MiniDSP but unfortunately have to connect by hardline via USB for Dirac Live. Back of Parasound Halo A31: Power cords from dual dedicated circuits. Big mamma red cables each go to the amps of two Tekton 4-10s. Blue goes to the 3 channel Parasound Halo A31 amp. And the little cord unseen goes to an Emotiva power strip where all the other gear is plugged in. Back of Tekton 4-10 subwoofer. Inside next to the 4-10 is back of Ulfberht biwired: And, yes, that's a power cord running over speaker wire [no bridges]. I even rub my stocking feet scooting them across the carpet before touching any electronics! Static pow boom kabow!

The subwoofer enclosure reminds me of Lanzar's minivan which set an spl record in the 90s. If I remember right it wasn't much over 140db. That was the first time I remember that I experienced 140+ spl. Interestingly, same as Clark Lanzar went w/ 12" woofers from the company's sub speaker lineup. They actually hit the hardest [loudest] w/ 12" rather than 15-18" subwoofers.

Looks like someone's neighbors broke in and dealt with the volume issues.

Today I sold my Onkyo PR-RZ5100 which was providing 3.2 channel configuration. Also sold my CD changer and MiniDSP w/ Dirac Live 3 room correction. My streamer is a Bluesound Node 2i and at this time I get to experience by no other option stereo mode with Tekton's Ulfberhts. My "preferred" audio world has now been turned upside down!
Lemme say that first of all while listening to the Ulfs w/ no room correction that I am not satisfied w/ the low end. I realize audiophiles sometimes want that "flat" frequency response. Well, I saw through Dirac Live's measurements frequency response down to 20hz. Meh, I appreciate the Ulfs mid to high frequencies the most. But I just can't live w/out the dual 4-10s. Thank goodness the Bluesound has a subwoofer output. I only need to acquire an RCA splitter to provide signal to both 4-10s. The Bluesound also has a crossover for the subs which I only tried momentarily to try the Ulfs for days or a weeks w/out any other low end fire support.
Interestingly the MiniDSP or from what I understand all Dirac Live processors limit sampling rates to 24bit 48khz after down sampling. I am told one cannot hear the difference between 48khz and say 192khz. Now that I do not have the Dirac Live processor in my signal path I must say that whoever said such a thing must be deaf. Either that or there's something else going on between the 48khz and 192khz albums offered between Tidal and Qobuz. This is the first time I've listened to 192khz streaming w/out the Dirac processor damming the signal. World of difference in my opinion as I can hear the increased dynamics and upper high frequency airiness to the room.
Stay tuned as my hifi setup "is a changing!" Teehee sounding like Ja Ja Binks! He's my favorite when contrasted to Yoda!
Enjoy, Shim

2.2 channel listening is becoming more pleasing w/ each passing day. Have to say it took me a brief time adjusting from the 3.2 channel front sound stage. Now after acclimating I'm pondering the idea of even pulling my center channel altogether and if I reintroduce a center in the future to task Tekton w/ a better matched speaker. I'd prefer a center channel w/ the 15 tweeter MTM array as well as the 4 7" midbass drivers of the Ulfs. Time will tell whether I put my current Tekton center channel up for sale. This is the first time I've listened through the Bluesound Node 2i's DAC and was pleasantly surprised to see a subwoofer out as well as active crossover in the unit. Using a RCA splitter to provide signal to both 4-10s works nicely. Best of all the Bluesound has an optical in! I can still enjoy television!!!

This evening I learned that TVs can transmit noise via optical cable even when off. Case: A BlueSound Node 2i's optical input has the option to "auto sense". When the TV is selected and sends a signal through the optical cable to the Node 2i the Node should switch to the optical as the source input. Only what happened when streaming the Node kept switching to the optical source from the TV because the Sony TV was transmitting noise. Heh, didn't understand why, don't know, don't care....... moving on. Remedy: resolved through reprogramming a Harmony remote. First, set the Node 2i's source to manual rather than autosense. Second, reprogram the Harmony remote when selecting TV for activity to also switch the Node 2i to "optical". Waaalaaaa! Lastly, I'm playing w/ the Node 2i's subwoofer crossover. @megashon, this might interest ya as you brought something to my attention regarding the "gut punches" in midbass territory during movie playback. At the moment I'm trying both 4-10s at 180hz low pass. Ya ain't kidd'n regarding the blow to the midsection when hearing gun fire etc during action scenes. Wish I could hear the 4-10s play to 300hz but the onboard crossover can't be bypassed as its highest setting rolls to 200hz on the dial. Curiosity has me...... what would it sound like if both 4-10s were bandpassed from 80 to 300hz and a pair of 21 inch subs performed the ground pounding action below 80hz? Kinda going after the areas Tekton Design offers w/ the Brisance's frequency response of 20Hz-350kHz. I'm tempted to pull the plate amps from both 4-10s and bypass the crossover:

Let me know when you are ready to sell it, it matches my white bedroom set of Tektons. Would sound much better than what I have have been using. 👍
