The Ohm Speaker is remarkable in what it can do in Crappy rooms, my neighbor has the ohm 3000s about 18 inches from a mirrored wall. The presence of the singer in the room is frightening. So life like. I have Maggie's 2.5 large speakers that would never work in his room. I also know my Vanderstiens don't like glass, and the JBLs will make your ears bleed at even low volumes. But Dennis, with all my ❤️ Heart I wish you would get a pair of these or find someone who owns them and listen. Rock, Opera, Jazz they just lay out images throughout the room. I had them over at my place for 2 days and have wanted a pair ever since. When you buy them the have a place to enter your room dimensions. I Bet in one of your rooms these things would shoot far above Thier price point...or tank because they sound best in crappy rooms.

Interesting. My living room is a nightmare for my 1.7i. Treatment is not an option. Plan on building a room downstairs. But want as good of 2channel as reasonable in it. I have been looking at Ohm 2000s. Ohm's seem designed to fit into the problems better.

I have the Ohm Walsh 3000's and they are night and day different from any other speaker design. I agree with not having glass as it's rear wall. I had to design a room with 17 foot tall glass wall because of our amazing view but I made the side walls and just behind the speakers sheet rock and lots of density to not sound like streaking nails down the chalk board.

How can a speaker fix a "crappy room". Are we ust chasing our tails here. Fix the room and then use any speaker type.

@yassinetalbi5884 3 ай бұрын

In some cases, allowing bass frequencies to pass through a material (like glass) can reduce the amount of low-frequency energy that bounces back into the room. This can help minimize standing waves and bass buildup, which can muddy the sound in a small or untreated room. So I don't see why that statement isn't true for you ?

Stay away from glass in all critical listening environments. It produces reflections that have a negative impact on room resolution at all frequencies.

@2:05 -- PS Audio's Aspen series speakers fire into the front wall. I do not believe that there is a control to defeat that firing-into-the-wall tweeter. I never heard those speakers. They have gotten very good reviews. But correct if I am wrong... Firing into the front wall compensates for either a design flaw, or an overly damp room. Richard Vandersteen's model Seven manual states: "The decision to incorporate the rear tweeter into the Model Seven was not an easy one. Even though it can produce some pleasing phasey phenomena as its output reflects 901 different ways off the surrounding walls, it is a second source for the information reproduced by the direct tweeter and therefore, its contribution to the sound field is significantly smeared in time and technically 100% distortion. (The front direct tweeter is already reproducing all of the high-frequency information on the recording, any increase above what is actually on the recording is by definition, distortion.)" Vandersteen's rear tweeter, however, can be dialed in or defeated entirely with its rear dial controls.

There are speakers that use front wall reflections to increase spatiality. This is another electronic compensation for a poor room.

A large glass panel window is just like a great big bass drum head, passive radiator! It will resonate like crazy at that frequency! Yes the modern Ohm's are designed to load to the wall rather than be moved away from it. But that is for a solid structured wall. Not a passive radiator drum head. Though drywall on studs can do similar things.

Take some measurements of drywall vs glass on the front wall to backup what you're saying. And not just frequency response. We need to see all the data. Its easy to trash talk something because you have a belief. I'd imagine drywall is detrimental to the sound in othet areas vs glass. Choose your poison. Everything with audio is compromise.

Question. They claim they want a front wall which is dispersive. Won’t a glass wall produce a specular reflection NOT a dispersed reflection? I’m not an expert, and not questioning the speaker. But I am questioning the marketing copy. Am I missing something?

Agreed. However, immersion can be just that with little resolution and possible some distortion. Remember bouncing energy off a wall and then back to your ears produces phase by having different reflection time signatures at the listening position.

Guys if you want to follow Dennis approach you will need to either build a proper room or be willing to roll a row of ACDAs around you including windows and open areas. This approach obviously works great but is not for everyone. You either need to commit or look elsewhere.

Bose 901's were designed where 8 of the 9 speakers were facing the rear walls to increase the spatiality, and when they first came to market, they were considered "high end" speakers. Now, they are the butt of many jokes in the audiophile world. They relied on reflected energy instead of direct energy, effectively the worst type of speaker design.

@AcousticFields 3 ай бұрын

Dr Bose realized that what we hear mostly as a final sound from any source is reflected energy. I believe he estimated around 70%. This truism formed the basis for his design and company. Unfortunately, reflected energy and resolution to not go together. All the more reason to treat your room for the negative impact reflections have on direct energies.

@Oneness100 3 ай бұрын

@@AcousticFields He probably got that 70% because he used an untreated room to arrive at that number. So, he's just boosting MORE reflected energy by his speaker designs in an untreated room. That makes a bad situation worse if you ask me.

@Oneness100 3 ай бұрын

@@AcousticFields What's humorous is that Bose released a Professional version of the 901 called the 800 Pro and then the later 802 series, where they removed the front facing single speaker, they turned the cabinet around where all 8 drivers were facing the audience. What a concept, now they are direct facing. 🙂 It was mildly popular in nightclubs and smaller venues in the 70's.

It would be very interesting to see you point out significant room and speaker placement no-nos that are shown in product marketing/advertising photos that are on very high-end speaker manufacturers' own web sites. Start with B&W and their 801 D4 photos. $42K/pair. Close to the wall, glass coffee table, etc. Oh but they're endorsed by a famous footballer, like that matters.

@Oneness100 3 ай бұрын

B&W have long been used by top recording studios for the TelArc and other Classical record labels in Europe, that's why they were originally touted as top audiophile speakers for many decades. Classical recordings typically don't rely on EQ or any signal processing and more straight forward recordings that cater to the more serious listener. Many people wanted the same level of speaker that top recording/mastering studios used during the creation of the recordings, so they could have as close to what the engineer heard. Abby Road is a famous studio that endorses B&W speakers. I don't know about the famous footballer you're referring to.i

Focus on the room's reaction. It will reflect back to the listener distorted energies from 800 - 2,000 hz. Our goal is less distortion, not more. The room dimensions do harm enough. We don't need windows creating more issues.
