Don't be a wuss! Get your saw out and be a man. I built these in six weeks. They put hairs on your chest and muscles where you didn't know you had muscles! They weigh 140pounds each.

They weigh 140pounds each. those days are loooong past bubba. in fact my first build was a refridgerator size REAL subwoofer built from 1976 "Audio" magazine plans.Sounded great,a bitch to place,sounded great,was butt ugly for far too long,sounded great.........and weighed in at an estimated 350LBS as my woodworking tools grew so to did my thirst to make "better" speakersa than i could buy (never happened ) Nope,the above,open baffles single panels or buy it ;D nice job BTW

Rick. My previous post contained a poor choice of words given your current predicament. Mike put me straight. Very best wishes.

I can't see the kit on the bottlehead site Rick? Look like a nice pair of NFM's, is it a dual concentric driver (AKA Tannoy) or a full range driver? Mike.

thats because there IS no actual kit just a "build this" article www.bottlehead.com/loosep/loosep.htmlas for the driver,just your everyday Foste FE 166E The Box ? Daytons.The box is a fully finished "blank" which means all you need do is drill holes for the driver and binding posts,stuff the box,then mount the driver Done !

Puffin, nice speaker build there, what design are they?
I'm thinking of building a pair of cyburgs needles next year, in the summer (such as it is!) and have enjoyed looking at the different speaker plans and designs that are around.
Are the drivers Fostex units in yours? Did you find a UK supplier?

Will. The drive units are Fostex 206E in a Fostex 208Sigma cabinet. I did a lot of investigating before making the cabs as I knew the wood alone would cost a fortune. I was assisted by Diyaudio and the World Designs website (Scottmoose in particular)
I used Baltic Birch Ply which was cut mostly to size by a local timber yard. The wood alone was £250. I got the drive units from Wlimslow Audio. I made them 3 years ago and have been totally satisfied with them.

Will Just remember that dual cone drivers, in general, roll off very quickly towards 20KHZ and aren't suitable for high resolution audio. I certainly wouldn't use them in a system with a Sabre. Alex

Hi Alex,
The needles I'm planning on building use a Visatron FRS8 driver, a 3" full-ranger (£8 each), so probably even 'worse' than the fostex dual cones. They'll be on the end of a standard chip-amp, and are really only for 'background music' rather than for proper listening/musical enjoyment, which is what my headphones are for.

Will I guess that we were spoiled years ago. Even Jaycar had a range of fabulous DIY speakers in different sizes and 2 way or 3 way. Later ones used Vifa drivers. Even now, Wagners in Sydney(W.E.S.) has a couple of great kits (Signature Series with Peerless Drivers and 3" Ribbon tweeters). They all come with precut baffles and panels, and are excellent value for money. Alex www.wagner.net.au/speakers/

But Alex, single driver speakers are so much more musical! BULLSHIT ! Miguel I wonder if the word "Musical" was coined by valve amplier lovers, to explain why the amplifier sounded different to the original recording, but they loved it's sound anyway ? "But it sounds so musical "

I've found that slim, floor-standing, single driver speakers also have a far greater 'WAF' factor than traditional speakers on stands. I've got it in writing and everything. Anybody got an 'under the thumb' smiley?

Musical and engaging , yes , perhaps with Apple "Lossless" files and MP3s . Some people are easily pleased.(especially wives) Why don't you swap your DCM speakers for a pair of them, and put the proceeds towards a valve amplifier that is more suited to such an antiquated design, but rediscovered for less discerning, or less affluent listeners ? They aren't too bad for non discriminating use as PC speakers in a small room, though. What is the point in having reasonable amplifiers with response only 1dB down (or less) at 20KHZ, when the speakers are not typically capable of even being 3dB down at 20KHZ? Have you ever looked at a frequency response chart for typical speakers of this kind ? Bear in mind too, that many decent headphones have a frequency response out to 35KHZ . (or MUCH better in the case of one Sony design.) Why go to all the trouble with 24/96 or 24/192 material , where the upper recorded frequency response is a maximum of 48KHZ or 96KHZ respectively, when you have such a savage HF rolloff. Added to that, the treble from this kind of "whizzer" cone is vastly inferior to that from a well designed tweeter. P.S. I was listening to designs like that while you were still in nappies !

Most likely not, but I think he still likes swinging on big nipples ? Which taste the best Miguel, pink or brown ? P.S. I more than likely listened to 300B monoblocks before you had your 1st wet dream !

The older the fiddle the sweeter the tune........ I think Miguel has a mother fixation and sees "big tits" as a comfort zone.... I'm sure "nappies" play a part in his fixation which is why I will ask the question again........ Got any pics of yourself in nappies Miguel?

SandyK once I'd heard ribbons, in my case Tonigens in the Heybrook Sextets Mk 1Vs (no Miguel tets not tits) I could'nt go backwards.
I bought a pair of s/hand ESS AMTs (the biggies) and the passive x/overs but I shan't be using those. I intend to go active.
So the plan has been for sometime to build OBs and big buggers at that. I had nowhere to work when I lived way out in Ortigueira, nor in Guadix but here I do have the space and the time until I buy the land and get planning permission.
My problem has always been finding the right woofers to go with the AMTs.
A few of years ago Solen/Canada was selling lots of Chinese transducers and one company had at least two models that would suit me fine - it was only a question of 15" or 12" - paper cones and both were about 99-101dB, the AMTs being 96.5dB.
All the other woofers I had seen were less efficient that the AMTs. Funny thing about the AMTs they do not like being enclosed.
Far from being a negative I see that as a huge advantage as it allows me to advance or retract the AMTs relative to the woofers.
My problem is that I did'nt make a note of the name of the woofer manufacturers and Solen stopped selling them and can't be bothered to check their records for it.
And before someone says something about bloody Chinese gear it's worth remembering that they now make virtually all the worlds transducers - Eminence being an exception.
Having heard both horns and OBs I know which floats my boat.
I am not constrained by the WAF factor, Angela is'nt like that and anyway I intend to emulate Michael Caine who had a house built for him in Andalucia at the end of the 60s. He, his wife and his daughter all had their own personal rooms and no one was allowed to enter the personal room of another unless their life was in imminent danger.
We each will be able to do what the hell we like in our own rooms - so my OBs can have baffles as big as I like aka what will maximise the quality of sound. They will be huge and I will do artwork on the baffles - well endowed hippy girls smoking huge spliffs WTF.
I have tried and tried to find that damn Chinese company - that's the only thing holding me up now.
Sandy/Robert - Rod Elliot has such a great reputation that I shan't look further for the active x/over.

Unfortunately it is quite common for chinese companies to close and open up under another name the next day. I have had experience of this in the optical industry, making spectacles one day and opened the next day making alarm clocks!!
It may be worth having a look through newer companys for your driver.

Andy, thanks for that. I would have bought at the time but for some reason post from Canada is horrendously expensive.
There's a big parts supplier in the States who had a load of special Eminence woofers bought as a job lot from a speaker maker that had gone bust but when I looked at the cost of posting these 15" woofers, it was going to cost 150% of the woofers costs.
With what I have detailed as per efficiency I don't need more than a couple of watts of class A and now that I think of it I am definately going for 15".

@solderdude
They look interesting alas my next DIY speakers seem a little way off at the moment, although thinking of replacing the drivers in my current DIY mains.

@ Robert
Should you ever be thinking about making electrostatic speakers ... (from 200Hz up) I know how to make one without it having a 'stretched' membrame ... meaning NO resonance point of the membrame !! Have never seen that anywhere before... can PM you pics ! NOT for publication or just anybody though, I would hate it if a commercial manufacturer runs of with the idea.
