My friend did some graphics design work for me so I built him a pair of speakers as a 'thank you' for him.  They sound very open and transparent so I was pleased with my first attempt at doing hifi!

No where near as good a build as yours but here's my humble 2.1 set up, sounds great! Seas and vifa drivers in the tops driven by rotel amp and neo bms 12" driver in the sub powered by 800w coming from two bridged coldamp modules.





The flash has kind of ruined the pictures and before anyone says anything they're not going to be set up like that for good they're just waiting to go in my new house! That's my parents basement.

Excellent parts. Do you find that listening to these types of cabs is just as enjoyable as listening to big PA. I only ask because when I got into it, I was hearing much more content out of small cabs than I would ever get for a PA system, and the imaging is a 1000 times better.

Tony,  To be honest I have NEVER heard a big P.A. that gets close to the sound of a good Hi-Fi system.

I think that part of the problem with imaging comes from the fact that because  the physical size of your typical PA stack is just so large and obviously multiple drivers especially at the top end no matter how well they are focused is just going to compromise everything.

I know that Line Array systems has got a bad rep on here but the closest I have heard a system to Hi-Fi was a small scale ground stacked LA.

I don't think that large scale rigs of any persuasion will ever be Hi-Fi in the proper sense at least with current technology.

Sorry about the quality of the photo, done in a hurry with my phone, couldn't be bothered to find the real camera!

Still very much a work in progress (although progress has stalled for some time).  There is a pair but thought a pic of one and the rack which runs them would be more interesting.

Ha, funny you should say that, I've found the same and I wasn't sure whether it was me imagining things.

It was a couple of years back (when I was less speaker geeky) so I don't remember what it was, and there were only three or four boxes in the array, so not enough to form a line, but it sounded great.

Seeing as I started off this thread, it's about time I posted a reply!

That's a nice set of custom builds you've got there Tony and they're some pretty serious mids you've got there!  Volt VM752's by any chance?

I see you've also been using 'ring radiator' tweeters, how do you like their sound in comparison to conventional soft dome tweeters?  I was very impressed with their performance especially considering the low price they cost!

Look foward to seeing yours as always!

I'd set up the floorstanders in a much more typical symmetrical fashion, however my mate decided that he wanted more stereo width and he found that the new arrangement caused less issues with reflections in the room.  Unfortunately it's a awkward room for speaker placement when considering the room characteristics and other furniture placement!  He's very happy now with the setup so I'm not going to try and interfere with his stereo setup now.,

Both very nice speaker by the way.

You've got it spot on!  It's a kitchen worktop, solid oak and 40mm in thickness.  I rubbed in some natural danish oil to give the finish a nice contrast with the patterns.

It was surplus to requirements from a friend so I recycled it, but it still cost me £200 for half a worktop sheet!

As for the other projects posted:-

perttu - very nice finish, superb quality - looks like the cabs have been veneered, how many ply is the exterior finish on those?  The reason you've had comments about kits is that they look too good to be homemade!  So that's a compliment for sure....  I still want to try veneering speakers but I didn't want to risk it on a build for a friend as I didn't expect that I'd manage to pull it off very well on a first attempt!

Tony Wilkes - your cabinets look understated (not saying they look bad btw!) however I can imagine they sound very clear and accurate.  I used to have some 'Living Voice' floorstanders which used the D2905/950000 tweeters and they had a very natural and non-fatiguing sound.  So would like to hear what yours sound like!

So Chris, your floorstanders look interesting...I was considering trying out some ribbons that looked just like those - I've always been very curious about ribbons but I know that they can sometimes be very difficult to integrate well.  How do you find yours generally sound?

And finally Ibex, wtf that is weird!!  Good to have some music whilst reading the newspaper during an extended crapping session :)

Hi Rossco, The tweeters in the cab are Scanspeak so they are expensive, however I have produced a cab with the same bass speaker, but budget domes and radiator tweeters, they come from within the same company group as Scanspeak. Excellent results but a more involved cross over to make them work, so sensitivity is down a bit. 
The mids ate Volts, All my stuff started life with ATC components, but It's easier to work with Volt and the mid unit is better.

Hi Rossco:

Regarding the ribbons, they are actually made by TangBand and distributed by Monacor.  They are very well made though and that is reflected in the price still being fairly high.  The soft dome midrange is from the same place and also very impressive.  The sound from both drivers is very natural and incredibly detailed.  The ribbons are particularly good on cymbals etc.

The integration between the two with a 5kHz passive crossover is pretty seamless.  I have more of an issue with the integration between the 10" and the midrange, probably because of the spacing, something which will be sorted in the final version.  One issue with the ribbon/soft dome combo is that one is set back into the baffle and one sits proud.  I can't hear any time/phase alignment issues but I will be setting the soft dome back into the baffle further to minimise the path length difference.

I'm wondering whether it would be worth the effort to build a transmission line for the Volt 10" drivers.  They work fine in the reflex box although a little EQ is required to bring the bottom octave up for a flat response.

I should really get round to doing an RTA measurement of them, I've just done it all by ear so far.

Also on the to-do list are the amplifiers, unfortunately my amp designs have stalled for various reasons, mainly lack of time.

Should fix all the cross over components including the power resistors to a piece of ply wood.
Or has that already been done?

I think i used 2 strips of about 0,3x1,5m ply. All ply was something less than 10 euros, so it's quite cheap. Veneering takes time and especially beech is quite hard to put on because of its long fibres (cracks easily when warming with iron). I can still recommend veneering and maybe it's easier to start with some ply with short fibres.

Ahh you've made my mind up now Tony, I was wondering whether to go for the upgrade... (ive got the non-super ATC's and you can't get the Supers at the moment).

Where do you cross the domes over at? (On the bottom end....) I see PMC use a 380Hz Xover ... but theirs may be modified?

I cross over at around 400hz. It took a while getting used to the fact that you have to crossover that high, from bass  to mid especially from a dedicated bass speaker. However, the bass speakers are linear, and it sounds very coherent.

I see. Volt seem to think the VM752 doesn't drop that low ? (They suggest 500Hz as I recall?).

Like all things Audio, you have to get the units and do the work yourself. All parts are thoroughly tested before they're ever applied to a design. My units go from 400 to 6K and are flat within 1db. The information from these units is incredible. Worth getting if you want the best.

Hi,

It's Alpha 6 and Beta 10, actually. The cabinets are solid aluminum, quite a bit of engineering: http://www.jumpingcactusloudspeakers.com/ - http://www.jumpingcactusloudspeakers.com/ . And the Alpha 6 sounds very good in the midrange indeed. As good or even better than the ones used in some €1000...2500 hi-fi speaker's I've listened to. It's amazing how cheap are the components used in many expensive speakers. And in addition, the enclosures and crossovers are often quite simple too.

The great thing about these laminated cabs is that you can profile your own shape inside, and generally get the wall thickness as thick as you want. This kind of facility is not easily possible with standard ways of making boxes. There are other manufactures doing these kind of cabs, but this one is one of the best I've seen. Hopefully it weighs a lot and doesn't move.

On a side note, I've always been told its better to put each driver (when you have a twin bass unit for example) in its own box? But I notice a fair few hifi cabs where this is not the case. Is there any reason not to let them share? (I know in the case of driver failure there will be problems but this is for hifi applications.....).

Just finished putting this lot together, taken best part of a year.

1 off 2.16 m long transmission line, Monacor SPH 165 CP
Designed with the Mathcad worksheet from quarter-wave.com
Outdoor plots of the TL matched fairly well with the predicted response, including LF roll off.

2 off Closed box mids, Scanspeak 15W/4424G00

2 off Soft dome tweeter, Morel CAT 408

24 dB/octave L-R 3 way crossover: 310 Hz / 2840 Hz
Circuit design courtesy of Elliot Sound Products.
Tops and mids running stereo, bass in mono.

3 off Sure tk2050 amps, running at ~ 27 V d.c.

Overall really pleased with the result, especially the mids, can definitely recommend the Scanspeak drivers.
Bass sounds clear and effortless.

Plot was taken in my living room, which measures about 4 to 5 m across.  The dips/peaks in the response changed quite alot depending on mic position so not really worried about them.

If I was building it again I'd prob have the bass in stereo and not make the shape of the TL take up so much floor space.
No complaints about the sound of the amps, but with no music playing you can hear the sound of the cooling fans.

Still got a bit of tidying to do on the crossover/amp cases but overall pretty much there.  Roll on the next project!

its a shame you used cheap speaker cable, something with a 90%+ silver content in the cores would give a much much clearer balanced sound, without the distortion copper provides by being resistant to certain audio frequencys depending on the resonance of the material blend.

Those TL subs are a thing of beautey, love the arrangment of the folds to make it, and the craftsmanship on them is amazing.

Amazing work!!

Don't worry, I've superglued lots of rare stones inside the enclosures so all will be well! Wink
 
The TL took a few long nights on autocad to get the panel drawings out, and fortunately miscuts were all oversize!
 
Just noticed this thread is half full of orange speakers, anyone else got any?

Mykey,
If that's the system I suspect it is, It retails for somewhere over

£100K as a very ‘Hi-Fi’ component! Seem to remember seeing it in a mag last year. It's goon be good but 100K good - I wonder?

Hi Mykey,

I guessed straight away the make of that design, it's by "Living Voice".

I'd used to have a pair of their "Autditorium Avatar" loudspeakers for my bedroom hifi system but have sold them now - surprisingly they were made out of chipboard(!) with walnut veneer on the outside which I noticed when I had a look at the tweeters(Scanspeak), I thought this was a bit pants for a speaker which retailed at £3000 new!  They sounded good but I needed to add a decent REL subwoofer to get a nice frequency range......

So here's a few more pics....

http://fastcache.gawkerassets.com/assets/images/4/2010/09/olympian1.jpg">

 

They look like excellent value for money....

"Pricing for the custom made Vox Olympian starts at £210000 (about $328700) and goes up, depending on the materials and finishes."
