I think the 157hz he was referring to is the +- 3dB on the Captivators

Good topic ... this represents a blind spot for a large amount of enthusiasts.

Love the details in the videos!

I think Arendal uses the hybrid approach in their 1961V sub. It starts to roll of at like 25Hz and has a "knee" at about 16Hz.

I've always been partial to Harbottle Audio and Funk Audio although they are definitely not on the inexpensive side.

Inflation may come back in the form of labor shortages, at least for a while. Many countries are aging out of having people to build things especially Western Europe and North Eastern Asia.

The video is pure gold. Thank you.

The video is pure gold. Thank you.

Great video, I like the way you answered the question a lot, from dynamics to amps, thanks!

Love This

I realy like the info you give us on youtube. Thank you!👍🏼😊

If i understand you right, for sealed pro audio driver such as lavoce, apply low shelf boost at the roll of frequency.

After many years of tweaking the hell out of my eq systems. I have learned to turn it off and enjoy my movies. I only adjust volume levels and distances. Nothing more and nothing less...

Thanks:- Forgive my ignorance. I’m not an acoustician or any type of engineer or technician. I do however, have a good basic grounding in the sciences and I do have a logical brain. I note that you and others often talk of time alignment” and “phase anomalies”. I sit 11 feet from my speakers which are 9.5 feet apart. If we work with the speed of sound being 1100 feet per second, then it takes 1/100th of a second for the direct sound from my speakers to reach my ears. Are you honestly telling me, that our auditory system is sufficiently acute as to be able to distinguish minuscule time alignment improprieties within 1/100th of a second to the extent that it notably degrades the audio reproduction? Really, seriously? I’ve witnessed Dr Floyd E Toole express an opposing opinion. Your comments welcomed.

Great info.

Thanks again for a well explained video.

Thanks for giving the DIY guys some love! Great info and gives me some extra things to think of. Currently running a Stereo Integrity HT-18 in a 12cu-ft enclosure tuned to 15hz (I was shooting for 18hz, but this was my firat slot port and missed a bit 😅) as my LLT. I've gotten things under control with my MiniDSP, but I've been using PEQ and not shelves. I'll give that a whirl. I also added 4 18" PA ported subs so having some fun trying MSO and multi sub placements. Currently have a pair in the front corners, and a pair behind the couch. Pretty great after a round of MSO with the HT-18 handling 15-60 and the PA subs doing 30-100.

Really interesting. I didn’t know a lot of this. I’m using Stereo Integrity Drivers and recently switched to all sealed. I use a single filter of a little boost down at 20hz and let Dirac with Bass Control do the rest. Definitely going to try doing some of this. However, I recently pulled the minidsp out of the chain bc I didn’t think I needed it anymore. My processor can do PEQ and shelf filters so ideally I’d want to use the shelf filter to replicate a LPF. Not sure how difficult that may be.

These instructional videos are awesome, so much info, thanks for sharing your extensive knowledge.

great video. a buddy of mine spent a small fortune on a REL 6 pack line array and was telling me all the reasons it is the superior subwoofer setup. is this subwoofer layout more audio voodoo?

Dad scores a 100! Lifetime memories right there. Good for you Matt. I envy you greatly.

I've measured Presonus Temblor T10 down to 20Hz. Pro sub. Very good. FYI, the Tonewinner SW-D6000 15" 800W looks likes the best value around right now... Have you tested either of them? Also, have you tested the Dayton Audio BST-1 PRO ?

Thanks for all your videos! I'd be interested in time and phase alignment of speaker and subwoofer using REW. Some subwoofers have contious phase dial and minidsp also has continuous phase dial, but alignment tool in REW doesn't seem to have continuous phase, just delay.

So I need an amp if I’m running matin Logan prodigy’s on my pioneer lx 505?I get around 97db at -10 that I have seen so far.

I see no issue with using bipole or even tripole if it fits the room or sitch. Atmos may be based on monopole, that doesn't mean that it can't be improved on

Here’s a different HT issue. 2016 Dolby Atmos demo disc in a Sony X700 4k BRP into a Yamaha RX-A3080 via HDMI. Playing the 5.1.4 channel test tones from the disc I get tremendous bleed-through during right side surround, ceiling front, rear, and again on left side surround, then ceiling front and rear. Front LCR tones are discrete, surrounds and heights are not. Do you have this disc? Have you experienced this issue? Anyone? wozzola113@gmail.com

You completely lost me after "Hi everybody" 😅, obviously I still have a lot to learn.
