  1. [quote name='stingraybassman' timestamp='1424775286' post='2700224'] I feel like someone should stick up for the OP a little bit here...... I'm guessing the design and prototyping of the Amp will be accompanied with a report/dissertation, half of the experience is finding the issues. This isn't a highly polished concept with sleek marketing and a huge R&D budget, this is someone trying to think outside the box (no pun intended), and do a project with some substance for university. A bit of open mindedness would help from everyone, he isn't going to harm anyone! (insert back related joke) [/quote] [quote name='skankdelvar' timestamp='1424905786' post='2701896'] T'is to be regretted if I seem daunting because that's not my intention. As Beer said above it's better to be realistic and questioning than give someone a pat on the head and walk away thinking 'That'll never work but I'm not going to upset him'. I mean, I could've just posted 'Nah!' and left it at that but I found myself researching the weight per sq foot of plexiglass for a given thickness, the gross weight of comparable amps and cabs; sundry other stuff. I even popped over to see a guy today who builds and repairs valve amps and had a ten minute chat with him about the project. He's been doing this for about thirty years. His reaction was broadly the same as most here: Why plexiglass when it only adds weight? You'd need an array of toroidal transformers if the bigger amps are to be movable. And there's only one guy in the UK (to his knowledge) who's built a 500w valve amp and that's John Chambers who was only able to do it because he wound his own transformers rather than stack up a line of proprietary jobs with all the attendant difficulties. I didn't [i]have[/i] to drive over to Somerset to talk about the OP's ideas but I did anyway. Frankly, I think the loosely defined scope of the OP's project is far more daunting than I could [i]ever[/i] be. And while it's nice to be kindly-spoken and 'encouraging' it's no kindness to let someone wander off a cliff out of a desire to be polite. [/quote] Thanks for the comments guys, this is a field that i am not familiar with, i am a spark and engineer to trade. however, this project concept is something different to whats available todays market and innovative (it wont be everyones taste. Engineered properly it will meet the stated weight and price). The setup is constructed or unbreakable polycarbonate in order to show the valve glow, show something different, allow for LED controllable lighting and perhaps be a talking point. Its worth noting that the point was to construct it to be small yet boast massive power. The design pictures that were posted are very basic as CAD and finite element analysis is still being completed on this model but this forum was to see what interest there was for this type of concept and how to improve it to make it more appealing (mentioned above). I realise i would have to wind 500w valve amp transformers myself, but thanks for asking your mate skankdelvar. Cheers guys
  2. [quote name='Musky' timestamp='1424733932' post='2699953'] What are those figures for - the 1x12? Presumably the SPL figures are 1w/1m with the higher one for the 4x10, although it seems to be a bit higher than I'd expect. I like the concept (and judging by the photos others have posted there are bands that like the idea too), but I can only really see two markets for this sort of product: Touring bands and home users. The touring bands will have their equipment roadcased and the roadies to shift it, and may well just be using for show with other monitoring options. It's also likely they'll already have a preference for the type of gear they're using. Home users would probably be happier using something much smaller and this really points towards a practice amp or small combo. So while I think the idea is good I think you're targeting the wrong market. You might find more purchase by offering a custom cabinet service for the touring musicians, building them to rehouse their amps/speakers, and/or building lower cost practice amps. [/quote] The sound range will depend on which setup is used, the concept is meant to be something innovative and different to anything on todays market, this concept will be designed to be portable but have huge sound. i was looking for information on how to upgrade or add to this product in order to appeal to a larger market, things such as covering the cab in a mesh to prevent scratching, changing plexi colors, lighting controlled by music, silent recording feature etc. then a specific market could be targeted. cheers
  3. [quote name='Jus Lukin' timestamp='1424693126' post='2699148'] I've actually discussed this design with the guys from a band I play with, so we will certainly watch with interest! The two main issues (outside of finding bands which the look will suit!) would be weight, and sound quality. Do you have and rough weights for the cabs, and how is the sound? Damping and so forth would be a little more complicated to deal with in a transparent design, although a black layer on the back panel might still give the light effect whilst keeping internal reflections down. There is of course the option to use them as dummy cabs for purely visual purposes. Colour me interested! [/quote] Thanks for discussing with your band , its still early stages as you can see, all i can say is the setup will weigh no more than 24kg (possible 20kg) and the sound range will be between 94db and 113db. if you have any other contacts then id welcome their thoughts too. What band are you in??
  4. [quote name='skankdelvar' timestamp='1424727386' post='2699820'] Ta, Skipper. I scrolled up and down [i]this[/i] thread several times thinking I was losing it. And - yes - I can imagine a certain [i]froideur[/i] towards the concept. Thing is, people, I don't get why entrepreneurial types don't join up in disguise and start stealth threads like 'What do you want from your next amp?' or 'How much would you pay for a 100w valve head?'. Handy research, I'd have thought. [/quote] This is a uni project, and having amatuer musicians involved in the project, more info is required which is why i am here. focus groups have been done with bands and distributors prior to this. The concept is meant to design and engineer something different to whats available on the market. this basic concept wont be everyones cup of tea however, it can be ammended to appeal to a wider audience. cheers
  5. [quote name='NJE' timestamp='1424692378' post='2699130'] I like the concept, the lights and plexi glass is a fun look and I think there is a market that would jump on it. My comments are: [list] [*]From my knowledge Plexi is pretty heavy, how does it compare to say birch ply that comapnies like EBS use. Weight is a key factor for a lot of people [*]Whilst I personally like the lights and think it looks brilliant, I think you will exlude a lot of players and narrow your market. I would never get away with using one in my bands, I play in Soul/Funk bands and it just wouldnt look 'right' for the band. [*]Would you consider offering something like a smokey grey semi transparent plexi which would satisfy some of us more conservative folk? [*]The angles speaker idea is nice, I think it would work well. Will they all be angled or will you offer a 12" flat front and then one angled so you could stack them and have one facing forward and one angled on top which would be closer to ear height? [/list] Good luck, as I said its nice concept. [/quote] To address your questions, yes there is weight in polycarbonate, the setup will weigh between 17 and 23 kg and should be small enough to be portable. The lights will be remote controlled with a range of functions, but can be built without them. Yes for sure there would be a few colours of housing .. grey being one. The front on these portable models will be angled to project sound, on future models flat to allow stacking.
  6. [color=#141414]Hey,[/color] [color=#141414]Im currently designing a concept valve amp/bass speaker for a uni project to take to market. its in early stages of development but will be constructed of plexi glass and lit with colour strips. Im looking for market feedback regarding interest in the product.[/color] [color=#141414]The spec shows the sizes and dimensions, the angle on the face to project the sound and some possible options. [/color] [color=#141414]The speakers selected were Eminence, Fane, Celestion.[/color] [color=#141414]The unit will come with wheels and an extention to pull it (making it portable).[/color] [color=#141414]Costing of the products would be - 12" setup, around £600. 15" setup, around £700. 4 x 10" setup, around £1000.[/color] [color=#141414]I also attached a picture to show an example of how the design should look.[/color] [color=#141414]Hope to incorporate a silent recording feature aswell.[/color] [font="Times New Roman"][size="3"][color="#000000"][attachment=184764:Sppec.jpg][attachment=184765:GuitarShow_18_zps02337708.jpg][/color][/size][/font]
