Original PROGRAM20 20% off Selected Sellers on eBay Deal Post

Cheap subwoofer option with advanced controls (level/cross-over/phase).
For those who may not want to spend double what they paid for their soundbar/bookshelf’s.

Discontinued product. Only 1 Year manufactures warranty according to Sherwood.
User Manual Link + Official website archive provided by alvian:
https://www.appliancesonline.com.au/public/manuals/Sherwood-…

Lack of after sale support (manufacturer warranty/product support) so best you will get is a refund.
10-inch woofer powered by slightly under-powered amp.
This enclosure is big (not in a good way) 40x40x40cm, makes it harder to place.
Solid sounding subwoofer if you aren’t pushing it (source: forums .)

Crossed this off my list, too large a box, too large a woofer, lack of after sale support.

    not enough doof doof

    • thebadmachine on 19/03/2019 - 16:10

      Yup you right there if you want doof, 150 - 200 watts RMS seems the standard usually for 10-inch.

  • Wystri Warrick on 19/03/2019 - 16:11

    My guess is 100 watts RMS, slot-shape down port.

    TA's subwoofer woofs at 1000 Watts and the slot is shaped up…

  • 51kabunka on 19/03/2019 - 16:54

    Not fully sick enough. You always need heaps more power to push lower frequencies than higher frequency.

    • thebadmachine on 19/03/2019 - 17:42

      Thanks very much.

          Frequency response 30-200hz not bad.

          • alvian on 19/03/2019 - 17:52

            @thebadmachine: No comment, as you know my sub is not the usual.

            • thebadmachine on 19/03/2019 - 17:56

              @alvian: Yeah the Dr. Frankenstein designed subwoofer. I imagine double-bass/bass guitar/guitar must sound glorious through that thing, even at high volume..
              But that makes me think. At high volume, is it accurate anymore for normal recordings? As in, the source should be a live recording when it’s that loud because you would be simulating concert listening levels, not your typical studio/standard levels.
              I imagine 6 x medium size drivers sound to move quick/accurate, but get low & loud enough, I can understand the concept.

                @thebadmachine:

                At high volume, is it accurate anymore for normal recordings?

                I cannot tell for certain because of my main speakers. They are an even more special creation by Martin than the sub. He only made one and it was so difficult to build he swore never to make another. I got to name them the Avalon.

                2 tweeters and 8 woofers per speaker in an isobaric arrangement. They are the size of a fridge. They go down so low that the Zeus doesn't have much to do most of the time.

                • thebadmachine on 19/03/2019 - 18:13

                  @alvian: A speaker that interests me, as in how it delivers sound, is the Beolab 90.
                  You may cringe at the fact it’s reffered to as a ‘digital loudspeaker’.
                  Apparently from people who have heard it; it has this ability to be tuned with a microphone to eliminate the perception of the source of sound coming from the speaker itself. And compensate for any room (I guess like an auto DSP tune mode).

                  I am just curious to experience it.

                  • alvian on 19/03/2019 - 18:16

                    @thebadmachine: $115,000. Westpac high yield investment and Tesla S territory.

                    • thebadmachine on 19/03/2019 - 18:27

                      @alvian: I just wanna audition them that’s all. Out of reach for myself and most people.
                      And limited numbers, my understanding was that it was sold out in most countries.
                      I’m just curious to know, what is really going on with these speakers.. a possibility after hearing them is I’ll curl up into a ball and fade into non-existence.

                      • alvian on 19/03/2019 - 23:45

                        @thebadmachine: I spent the last hour writing down my thoughts on the Beolab 90 and I was about to post it when the bloody browser crashed. It is now half past 11 and I am in no mood to rewrite it >-(

                        So instead here are a few thinking points.

                        • correction: Martin only made one pair and it was they were so difficult to build he swore never to make another.
                        • $115,000 seems to be the price of one Beolab 90 speaker.
                        • The idea of making speakers sonically disappear is not new. Amar Bose tried it with his Direct/Reflect theory and the Bose 901. The 901s do disappear but all music get scaled up onto an unrealistically large diffused soundstage.
                        • MBL is still developing the Radialstrahler omnidirectional speakers. Problems: diffused soundstage (I cannot see how you can avoid it with omni speakers), inefficient drivers, listening rooms need heavy acoustic dampening, very high power amps needed. I heard a pair of mark 1 before, I wasn't convinced relative to their asking price.
                        • B&O uses dynamic drivers to overcome inefficiencies. It uses DSP to focus the soundstage, to control dispersion, and to decouple the speaker from the room. I haven't heard them so I will make no comment on its performance. However, no amount of DSP will overcome the lack of a second speaker, you still need a pair to satisfactorily reproduce stereo sounds.
                        • thebadmachine on 20/03/2019 - 01:00

                          @alvian: The Beolabs look it but they are not omnidirectional, they have a front and a rear.
                          They have a sweet spot just like normal speakers, apparently the width of the angle of the sweet spot is adjustable.
                          Yes the price is for one, but they are meant to be bought in pairs and used in stereo.
                          According to a long winded article I read awhile ago:
                          They are meant to be listened to as conventional speakers are (there is a target listening area, although it is much larger area covered than normal). (Many mentions of B&O claiming this allows for you to truly have the same experience when listening to music with other people.)
                          But the most surprising part was that when walking all around the room (which was a large room with high ceilings/high windows with large tall curtains, shared with a few other people, kind of like an “art gallery” setting, with a pair of Beolab 90’s against the wall on then long end of the room) he noticed strangely how the sound did not change at all wherever he went in the room. It did not even sound like the sound was coming from one side of the room.
                          And that this was the most memorable thing about the speakers that stuck with him after listening to them. He explained it as with a traditional speaker sound changes quite quickly/dramatically by becoming off axis or changing your position. And he didn’t doubt it was still happening with the Beolab 90’s, only it was to the point of being barely noticeable. He also stated if he really forced the sound to change (crouching in the corner and putting his head up against the wall) he could hear a change in the sound, but in all normal circumstances or positions (sitting or standing around the room) the sound stayed eerily consistent.

                          • alvian on 20/03/2019 - 01:25

                            @thebadmachine: This demo mentioned 3 modes: focussed, wide and omni, demoed the former two. You can shift the sweet spot with an app in focussed mode.

                            Technical Sound Guide section 5.1.3 describes and measured omni mode.

                            http://www.tonmeister.ca/wordpress/2015/10/06/beolab-90-behi… There are backwards pointing drivers, omnidirectionality is one of the design goals.

                            • thebadmachine on 20/03/2019 - 01:31

                              @alvian: The video I saw (by B&O I think) mentioned that they designed it with a clear front & back, as they are meant to be positioned for focused listening. And then have the option to go Omni-mode for ‘social gatherings’ etc. Yes and shift and control the size of the sweet spot from what I remember (pinching gesture on smart device)
                              They were never designed to be bought and used as a single Omni directional speaker. Although the price may make you think so.

                              • alvian on 20/03/2019 - 01:37

                                @thebadmachine: Please read the Behind The Scenes blog. This is the origin of the third design goal. Directional steering with a circular array of drivers. Omnidirectionality is its byproduct.

                                Two members of the Acoustics Department, Gert Munch and Jakob Dyreby, had been collaborating with two graduate students (both of whom started working at B&O after they graduated), Martin Møller and Martin Olsen on exactly this idea. They (with Finn Agerkvist, a professor at DTU) published a scientific paper in 2010 called “Circular Loudspeaker Arrays with Controllable Directivity”. In this paper they showed how a barrel of 24 small loudspeaker drivers (each with its own amplifier and individualised DSP) could be used to steer a beam of sound in any direction in the horizontal plane, with a controlled beam width.

                                • thebadmachine on 20/03/2019 - 01:41

                                  @alvian: Yes I think we are having a misunderstanding, my definition of an omnidirectional speaker, is a speaker that simply sends equal/identical sound in all directions. (It can be a single upward facing driver)
                                  What this speaker is doing as read in your exerpt, is using this omnidirectional array to steer or bend beams of sound, so therefore it is not Omni-directional in my opinion, it is sending reverse frequencies or whatever it’s doing out the back to affect the sound in the sweet spot (which apparently can be as big as the whole room).

                                  By the way as I started watching the video, I would have just told him to let us listen to the speaker first, then explain the magic later, but since I am not there in person, i am interested in what he has to say.

                                  • thebadmachine on 20/03/2019 - 15:45

                                    @thebadmachine: I consider Omni-directional to be the same sound all around the speaker from the speaker’s centre point. I am technically wrong, but that is how most would understand a Omni-directional sound experience.

                                    By the way I found something else that may interest you:

                                    The JBL Paragon.

                                    Now the music in the demo is not to my tastes.. I don’t know what they were thinking with the first track, and the second is the typical pretentious sounding vocals, with the last being stereo-typical Jazz.
                                    Have you heard of this YouTube channel?

                                    Kendrick Sound modifies classic speakers with specific cross-overs etc
                                    In an attempt to better or update their sound.
                                    Majority of their products are JBL but there are a few other gems in there (such as the Harbeth HL5). They got the demo track spot on for this one.
                                    Also enjoyed watching these:

    Sherwood?

    Are they still around??

    • thebadmachine on 19/03/2019 - 18:00

      I wrote in the description they left the country. Or possibly disappeared into a hole.
