In the 1960's my father owned a pair of Wharfdale speakers (don't remember the model). Each of the two stereo speakers had six drivers, two 12" subs, two 8" mids and two tweeters. The cabinets were constructed of a double wall of 3/4" plywood with a space between walls filled with dry sand. Heavy is an understatement. I eventually ended up donating them to the local children's theater for auditorium filling sound.
Woah, that was heavy, man. Ok, the rules that everyone works with when designing speakers have been with us for many decades. The differences in speakers is in the combinations of these rules and the extent to which each one are employed. The infinate possibilities are what keeps the art alive.
When I was an audio/video salesman, one of my demonstrations was to have the customer pick up the product. TV . . . stereo . . . heavy meant bigger parts and power supplies. Hitachi used to win the weigh competition a lot . . . of course, Carver and NAD figured out how to be more effective/efficient.
The heavier a speaker is normally means better quality drive units. Big motor structures weigh.. Top subs weigh a ton due to huge magnets.. My speakers are 57kg each and my sub is 63kg.. They don't get moved around much.😂
To some degree, yes. But as a general rule the biggest difference in weight will be from the cabinet construction/materials. Also if the speaker has a self powered woofer(s), then the associated electronics will obviously add weight. Often I see two similarly sized speakers with same number of drivers and a large weight difference. I would avoid the light speaker. It is bound to have audible resonances somewhere in the response.
I love my old Spica SC-50 speaker with the round back. They are made from a cylinder but with a flat front baffle and a flat top. Not the best but very good for a smallish speaker. With French Audax 6.5 inch woofer and dome tweeter. They had thin foam around the speaker but it rotted. I'd like to find some replacement foam and upgrade the crossover.
I’m a noob when it comes to this audiophile hobby. But I love physics and strictly speaking from a physics perspective, the two best solutions for a speaker cabinet are 1) to get rid of the cabinet completely - e.g. open back speakers that emit in a dipole fashion (because the sideways waves will cancel themselves out)...OR 2) create a spherical or egg shaped speaker box that won’t create any standing waves (however in that case you have to deal with vibration of the cabinet itself so that adds levels of complexity to the design.) I recently came across these Egg shaped studio monitors that from a nerdy/physics perspective and from an aesthetics design perspective are pretty cool. They are the Munro SE Egg studio monitors. And to put my money where my mouth is, I recently purchased a pair of open back speakers - the Spacial Audio Sapphire M3s. They are a genius design in my opinion both from a physics perspective and from an aesthetic design perspective as it marries the two perfectly. They have a beautiful, museum quality bauhaus contemporary design that are both elegant and sound amazing. Who wants to have to re-create stone henge in your living room to get great sound? I sure don’t!!
I remember seeing a cut away B&W matrix 801 at my HiFi shop years ago and was amazed at the bracing. I wonder though, if weight is added in some things just to make them appear to be substantial. The remote for my Primaluna amp weighs ¾ pound, that’s just silly and actually makes it less useful because it’s too heavy.
The matrix in the 805 was much better than the 801. B&W had a speaker called the Matrix 1 that was seriously matrixed with the foam inserts but reviewers found them dead and uninvolving.
@@carlosoliveira-rc2xt I would love to see B&W build the enclosures and KEF build the drivers on some speakers. The newer KEF's look a lot like matrix enclosures though.
The round speaker, among other shapes, was suggested in an enclosure study by Harry Olson in 1951. This was presented to the Audio Engineering Society. The PS Audio project certainly looks interesting!
Harbeth 30.2 are 26lbs. For a speaker about 18x12x12 and only 2 drivers, I would consider it average in weight for its class. Checking other models I found the same. They may seem light but they are rather small.
@@r423fplip The weight comes from somewhere though. Bracing? At any rate the finest sounding speakers made have nonresonant dense enclosures and as a result have significant weight to them. Harbeth speakers even though still somewhat resonant are less so than in earlier years. There is more than one way to skin a cat and very few choose to work WITH the resonances In order to ameliorate the deleterious effects. Most at least include cabinet density among other things in the fight against them.
jeff lynne I am lucky to have my dream speaker, the Graham Audio LS 5/9, totally have fallen in love with the sound they make, timbre, clarity, the fantastic sound of piano or violins, wonderful speaker with jazz, but also very capable with blues and rock, could not be happier, have had 2 pair of speakers before, both using the thicker and heavier design philosophy and they sounded very nice too, but there is just something special about the Graham’s, they also work wonderfully on lower volume. They look like hand built speakers instead mass produced ones too, which is nice, just gorgeous. ;-)))
The Emit died? Get a new $25 ribbon on eBay and save a fortune... If the round speakers were ugly but was a better sound why not build a round box inside of a light square exterior box?
I’m totally biased towards heavier gear, if I pick up something that’s lightweight, I put it right back down and keep searching for heft...be it massive power amp and or tiny headphone amp lol
Gotta agree. Though there are great bookshelf type speakers ($2-10k yikes) large floor standing speakers are better if you have the room. Same for class A (or A/B) for amps.
Paul , what year did he do the round speakers? I built a pair using a 6" woofer and a few small horns on top. This was 1978. Yes the sound was impressive.
Harbeth HL5 Speaker cabinet are made to absorb energy and they are heavy cabinet so it depends on the manufacture design and thought process in what he believes in. I have a pair of HL5 speakers and are very open transparent sound.
Paul, when do you expect the Stellar line of speakers to be released and about what price point? May wait on new purchase to give yours a try. Thanks for the great info
He mentioned it in a recent longer "talks" video from a show. I don't know if its that specific model, but I believe the cheapest or maybe second cheapest model was estimated at 17.000$ ?
The Stellar line is going to be the more entry line, which will be more affordable. I did see that video and the top of line models look great but out of my range.
@@mrhatch117Plywood may be more physically robust than MDF but MDF is definitely less resonant that plywood because of the fibrous nature of the core and therefore a potentially better choice for a speaker cabinet.
@@avsystem3142 don’t disagree with you. Stiffness of the enclosure definitely changes the sound/tone and resonate frequencies. I just don’t like MDF as you well know the pitfalls.

not always. heavier weight can be due to many things. heavier material, more bracing or simply because it's bigger. none of these can ensure elimination of audible panel resonance. what you want to look for is a proper bracing which is almost impossible unless they have a cutaway model to show you the inside of the speaker. a proper bracing needs at least connecting each panel to another perpendicular panel. connecting a panel to the opposite one is pretty much pointless and is a waste of time and resource. this is one of the reasons when it comes to speakers, i'd prefer DIY approach.
"connecting a panel to the opposite one is pretty much pointless and is a waste of time and resource." Joseph D'Appolito, Phil Vafiadis and AR Bailey might disagree with that. It's what you do when building a folded transmission line cabinet. OTOH if you build a _straight_ transmission line as a friend of mine did, you end up with a tapered box that's 3.6 metres (12 feet) long. Unwieldy to say the least.

Disagree. Bracing a panel against a parallel panel shifts the resonances higher in the frequency range. For a bass resonance that would ameliorate the deleterious effects of said resonance. Low frequency panel resonances are the most destructive and easily heard. They tend to stay around longer. Perimeter or window bracing is the easiest type to make in manufacturing and the most commonly used. With that said the effectiveness of a brace is greatest at the mid point of each panel.

Also heavy speaker's do not move around so much from bass because of the force from the cone.
