Thanks to Brandon (Beast) for hosting a great GTG. Beast has a heck of a theater room and the upstairs AV123 towers were pretty damn nice too. What’s even better about this GTG than the awesome equipment is the world class guys that attended. We definitely had some personalities there but everyone was incredibly nice, knowledgeable, and just simply wonderful. As an aside, there was quite a bit of money laying around in a few piles for supplies and food and no one touched it. A little thing maybe but for a bunch of strangers getting together, that is awesome trustworthiness and speaks to the character of the guys present. I truly enjoyed the experience of Brandon’s awesome theater and am fortunate to have made some friends with great guys.Disclaimer
– I brought the LMS 5400s, Noesis 212 HT-LPs, and SpeakerPower SP2-8000. Shouldn’t affect my impressions but want to be open.Primary Equipment We Listened To:
- Peavey IPR-7500 – primary amp driving SI HS24…until later in the evening.
- SpeakerPower SP2-8000 – primary amp driving the pair of LMS 5400s and later in the evening, both voice coils of the SI HS24.
- Stereo Integrity HS24 – 15 cu.ft. enclosure driven off of a single channel of a Peavey IPR-7500 most of the night. Then we hooked up both channels of the IPR-7500 to the HS24. Finally we hooked up each channel of the SpeakerPower SP2-8000 to a voice coil on the HS24…more info in Round 3.
- TC Sounds LMS 5400 (Ultra) – Pair of tried and true LMS 5400 18” subs in 5 cu.ft. enclosures. Powered by the SP2-8000 amp.
- Stereo Integrity SI18 – In the picture, Beast’s Danley’s are flanked top and bottom by a set of dual-opposed SI18 boxes for a total of 8 subs. These are run off of a single channel of the IPR-7500.
- Danley SH50 – These are Brandon’s main speakers and were used to compare against the Noesis 212s. Has the BMS 4550 compression driver, which is a step down from the 2-way compression driver used in the Noesis 212. Also has four 5" drivers for midrange and a pair of 12" woofers. Sensitivity of 100 db.
- JTR Noesis 212HT-LP – Brought to compare against Brandon’s Danley’s. Has the 2-way compression driver, 4593 ND, and a pair of 12" woofers. Same sensitivity of 100 db.
Additional Equipment (helped in our listening/testing):
Round 1: Stereo Integrity HS24 vs TC Sounds LMS 5400s
- Speaker Switcher – NathanJs automatic speaker switching magical box. Very nice and Nathan says he’ll share some info…I posted it so it's official...Nathan will now have to share info on how to make this awesome contraption.
- Speclabs equipment and $2000 mic – Thanks to BossoBass and his son for bringing the equipment necessary to grab some awesome captures of the listening experience. It was pretty neat to hear a difference in equipment and then see exactly the difference that was measured.
We started off listening to the HS24 with a 9 track set and then moved to the pair of LMS 5400s. My initial impressions of the HS24 is that it is a beast of a single sub. It was clean and articulate (airy – right Nick?
) and seemed to handle everything we threw at it. Then we switched to the LMS 5400s and it seemed like more of the same. Then we started doing some back and forth and I really couldn’t hear a difference between them…until we got to a 7 Hz signal. The HS24 was clearly audible at 7 Hz while the pair of LMS 5400s didn’t produce much audible sound. And the Speclabs captures showed what we heard, which I’m sure Brandon will share when he gets a break from being an awesome host.
Now this is my subjective thought that I cannot truly validate without some additional critical listening. Were the LMS 5400s cleaner at the 50-80 Hz range than the HS24? I initially thought maybe but I’m not sure. Is it me wanting my LMS 5400s to sound cleaner…I don’t know? I will say they were close and I MIGHT give a slight nod to the LMS 5400s at the upper mid bass range, equal in the 15-30Hz range, and the HS 24 at under 15 Hz. I think it is truly amazing that a 24” subwoofer was that clean from 100 Hz down to ~7 Hz. I would say 2 of those in a room would handle/destroy most normal size rooms with AUTHORITY, even for the AVS bass freaks!Round 2: Danley SH60 vs JTR Noesis 212 HT-LP
For this one, we went back and forth in real time and occasionally backed up to listen to a section of a test track a second time. We initially had some problems with the Noesis but thanks to BossoBass’ son for figuring it might be a phase issue, we finally got the Noesis sounding like they should.Soundstage
– clear winner – Danley. I’ve always thought the Noesis had a pretty wide soundstage but they seemed thin in comparison to the enveloping nature of the Danley. I guess that is to be expected as the Danley’s are all horn and at least twice as wide as the entire Noesis cabinet, much less the 212's horn. Noesis on their own have a nice soundstage but the Danley’s simply owned this category.Upper range
– clear winner – Noesis. In my opinion, the Noesis were the clear winner as they extended right up to the 20,000 Hz most humans can hear…humans with good hearing that is (not a given on the AVS forum
) I’ve heard many quality speakers and headphones and I can tell when I speaker doesn’t hit the 20,000Hz range and the Danley’s fall into that category. This was also backed up by Speclabs, which showed the Danley’s having reduced output from 16K to 20K. Now up to 16K, I think the Danley’s had a very nice sound but so did the Noesis.Midrange
– winner – Noesis. In my opinion the Noesis sounded better in the midrange, especially with vocals, than the Danley’s It wasn’t as clear cut a win though but the Noesis were slightly more articulate and detailed in the midrange.Midbass
– depends – The Danley’s clearly have more midbass, which for home theater is outstanding. The Noesis don’t have as much midbass but aren’t slouches by any means. I also felt it was pretty clear the Noesis were more articulate with the midbass, where the Danley’s had a heavier character.Overall
– While we were setting up the equipment, Brandon had music going through the Danley’s. Since I was up front setting up the LMS 5400s, I was able to listen to them for quite a while although nothing critical as I wasn’t intimately familiar with all of the tracks. I really liked the Danley’s and I was looking forward to hearing them in our testing. Like I said, the Danley’s just create a wall of sound that completely envelopes you. The Noesis project a nice soundstage but seem like amateurs in comparison to the Danley’s. Other than midbass impact, I felt the Noesis were the better speaker, especially if you are a critical music listener. If you just passively listen to music or watch movies, especially action flicks, then the Danley’s should definitely get your consideration. I and several others mentioned how much we would like to see a Danley Noesis, a little smaller than the SH50 would be nice too while we’re helping in the design. Round 3: Movies with the Stereo Integrity HS24 (8,000 watts on the Sub!!!!)DISCLAIMER!! The Stereo Integrity HS24 is not rated for 8,000 watts so please do not try this at home!
After dinner the talk was about hooking up each voice coil of the HS24 to a channel of the IPR 7500 to see if we could destroy the sub. I believe within the first track played, the IPR 7500 went into protection mode on one of the channels. We measured the voice coils and found them to each have an impedance of about 1.6 ohms. So then we hooked up each channel of the SpeakerPower SP2-8000 to a voice coil on the HS24 and let her rip. The HS24 took all 8,000 watts of the SpeakerPower and the more we turned up the volume the more it took…and then after a few tracks of steadily increasing volume, the SP2-8000 went into protection mode on one of the channels. So we backed down a bit and then continued our testing/listening. Our movie watching and listening was primarily focused on scenes with low frequency output. Hulk, Battle: LA, How to Train a Dragon, and a few others that escape me right now but they were all awesome. It was amazing how much bass was coming from the single HS24…felt like it would shake the house apart. Even more interesting were the Speclabs plots that BossoBass and his son measured. It was especially interesting to see how the raw signal (looped back and measured) compared to the microphone measurements and how close the system output was to the original signal. Awesome experience.Round 4: The Beast System in Full Effect
So we ended the night (for me anyway since I had a 2 hour drive home) with the Metallica – Through the Never concert disc. We started with the HS24 but Brandon decided it wasn’t Beast enough and so he switched back to his personal 8 SI18s. As impressive as the bass was from a single HS24, Metallica and +10 over reference was truly an experience, especially with the added visuals of a 138” projection screen. The system sounded awesome, amazing, astounding, and any other adjective you can think of. As others have said, it is the best theater experience I’ve ever had. The great people involved were icing on the cake to a truly enjoyable day.
Edited: I removed the part about the 228HT using the same compression driver as the Danley. I was informed the 228HT uses the 4547, not the 4550.
