Steve headed up many projects for AE, his last notable achievement was the AE22 studio monitor working with freelance designer Phil Ward. This speaker is sealed box, an 8" woofer with large underhung motor and 50mm VC, straight sided AL cone. Low thermal compression, high power handling, and excellent time domain response were the targets for this model.

Steve took these principles for his own speaker, added a very strong,low colouration cabinet and sourced the best bits he could find, including many made in the UK.

This is the price of hand made in the UK with some of the best parts available.

Yes, ATC, AE etc are all in the Stroud area. Not surprisingly there are a lot of technology companies near Cheltenham.

BTW why is the thread locked? Reading the thread I saw my name and Googlebot as the "people" viewing. Is this why?

Confused So I reopened it and merged threads, odd that so will keep an eye out.

Back to the speakers, have heard a couple of Magico systems, great timing involvement could easily live with a pair Smile

It's always useful to track down a speaker's review from one of the 2 main German magazine ( Audio and Stereoplay ) as they include distortion graphs at 100 dB and it's interesting to see that in spite of all the high tech in Magico they still don't manage to bring down distortion to ATC levels .

Perhaps another one for Martin in his pro-monitor round up?


Hi folks. Just thought I'd join in the chat as I'm intrigued why having Scan Speak drivers could be seen as a negative as, in my opinion, they are one of the best driver manufacturers in the world. Maybe assumptions are being made that the drivers used are standard stock components..... They’re not. They are tuned in-house to hit certain target performance characteristics for our speakers that enable us to keep the crossover component count down to a minimum.

As well as wearing my SP Acoustics hat I also hold the challenging position as development engineer for Kurt Mueller in the UK so tuning driver cones and suspension parts is a speciality.

We are proud that Scan Speak manufacture the drivers in our speakers. They have a team of very talented designers and to be able to have them behind our products is a real bonus for us and our customers. I get to work with a lot of transducer designs and designers so it should say something if I’m willing to put my companies cash in to someone else’s pocket. Those of you who are familiar with Scan Speak will know that they are not a budget brand.

It is hard to pin point exactly who designs what in this business. Don't be fooled by someone accrediting designs to themselves (or someone else). It is rarely the case that one person is responsible for a complete design of anything these days no matter what claims are made - most things are variations on a theme and have teams of designers behind them. Sometimes component parts within a product carry the brand name, not because they designed the part but because they order enough parts to have them OEM badged as theirs. If we ordered 10,000 woofers from Scan we could probably have them badged as original SP Acoustics parts, but would we want to? Probably not.

Steve,

Many thanks for taking the time to reply and correction of any errors. My apologies if I have said anything incorrect. Blushing

I didn't intend to put down Scanspeak drivers or your use of them, it was more the emphasis that it wasn't such a ground up exercise as the AE1s. Of course you could argue why invent the wheel. Without wishing to sound wise after the event I thought of putting comments about tuning/rebuild/OEM specing the units but this being the internet fairness to all doesnt always happen mainly driven by being called an audiofool despite being being paid to work in audio.....I was reporting my conversation with evangelical users/listeners and I am happy to report their keeness.

Ashley,

There weren't any errors on your part that you could have been aware of and I do understand your comments I just thought I'd clarify what isn't obvious about our speakers. RollEyes I have had experience of people trying to copy our SP1 using the stock Scan components and wondering why it doesn't work as they expected. The Scan Illuminator drivers are, in my opinion, about as close to a perfect driver as you can get within reasonable parameters so to try to design something better (or just different for the sake of it) seemed pointless.

The AE1 was (or is) a speaker that has grown and changed over time. The original driver for that was a modified copy and was made by someone else not AE, but that was a long time ago and has been forgotten in the passing of time. The tweeter is an old catalogue model from Seas with a slight damping mod to the rear chamber.

The later AE1MkIII was a bespoke neo woofer, one of the first; it took the combined efforts of 3 of us to create it. I was one and you probably are familiar with the other two but as they were contracted for the job so I can't name them. There again that driver is made by Scan and the tweeter is a stock Scan part.

Who'd have thought it.....Smile

there is just a hint that we might get a mid range , whatever that is

Magico sealed box, mid this year , for review

the only worry is how to pick it up and place

it they are very dense indeed

If it's too heavy why not the Vivid Giya 1 or 2 instead - just as high-tech and lower distortion than the Magicos in spite of a port ( but a sophisticated one )

how can you know this ?

I do think Laurence Dickie has done great work with the Vivids

but your assertion must be just that unless you have a good argument assembled.

I will wait to find out

The 2 main German magazines ( Audio and Stereoplay ) always publish a distortion curve for 90 , 95 , and 100 dB over the full frequency range.

The G1 had the lowest distortion of any speaker I've looked at even in the bass ( sub 50 ) which is very unusual ( review 7/2009 )

I have a pair Q5s at home right now. I think about 250kgs of solid metal each ... fine tuning the position is a challenge to say the least !

I remember that in the 60s AUDIO magazine had a feature article on some concrete horns that an audiophile had constructed on his lawn for outdoor listening. They weighed a couple of tons each. A harbinger of the future? Perhaps our hobby will be known a HEAVY-FI rather than HI-FI. Personally I am giving my gear a weight reduction program having just sold my Duetta Signatures and putting my Basis Exclusive up for sale. Even my CJ 350 is not entirely safe. I like to shuffle my gear and like lifting heavy objects less and less. Perhaps I should sell it all and buy a 25 lb. MP3 player?

They are still breaking in (less than a hundred hours on them), so you need to keep that in mind. Also, keep in mind that I've lived with Magnepans for 14 years, so I am quite willing to forego heavy bass for a realistic and transparent performance everywhere else. Others may not want to do that compromise. My listening is mostly jazz of the acoustic variety (anything from big band to solo instrument and vocals) and I never listen to death metal/punk/eletronica/ hiphop/drum'n'bass and other stuff of that sort.

The Q5s have a similar sound to the Mini 2 (if you've heard that speaker) but with a lot more bass, and as a result is much more fleshed out from the midrange down. It is also more dynamic, goes louder, has a much bigger and deeper soundstage. The speaker is planar like in the mid and highs (with a lesser enveloping sound than bipoles can throw) in that it is extremely transparent and unbelievably detailed. The heroic cabinet construction makes it so easy to hear every instrument or voice in a brass section or choir perfectly; there is no smearing at all. Unlike planars, it has a fantastic bass reproduction that goes down to mid 20s (I believe), BUT this is not headbanger bass. Some people may therefore find its bass restricted, though for my ears, there is more than enough of it. As per the rest, there is no smearing whatsoever and you can follow and hear each note in a double bass line clearly and distinctly, even at the deepest registers.

At very high volumes, I find the treble a bit aggressive on some material, though, as I have mentioned, they are not broken in yet and therefore I have not yet finely set them up. Toeing out a bit more might help - the Mini 2 had a hot treble on axis. Also, I might be oversensitive to highs - I had dropped the level of the Maggies' ribbon tweeter by a couple of dBs as I found it too 'hot'. Finally, these speakers perform their best on vinyl, and open up a bigger gap between CD and vinyl reproduction!

Will write more after I have another 100 hours or so on them, and fine tune their position/toeing.

I had to do a show at a Bristol auditorium that used the entire front of the stage as the mouth of a bass horn underneath the stage area, driven by four 15" drivers. Mid and treble was by multiple units scattered around the ceiling throughout the rest of the auditorium. What did it sound like? - absolutely terrible, horrible squawky mid and treble which varied dramatically as you move around, all accompanied by stomach-rumbling bass.

I have paid more than lip service to bass timing, though looking back , partly out of necessity, my timing emphasis has been low mid to treble based, particularly for sound sources and amplification.

Over the course of loudspeaker reviews, low frequency timing has an issue but few speakers really nail it and there is a tendency to go with the general status quo if only to avoid condemning most of the field for a few that trade bass extension and efficiency for timing.

When large enough, speakers such as Wilson Maxx3 with extended low frequency bandwidth, greatly resolve the question while for a smaller scale design such as the DSP active model Meridian 7200, with on board group delay compensation, nailed the issue showing that extended bass with excellent timing and extension was possible from a relative compact bass reflex design.

Recently I have experimented with a three way with the facility for adjustable bass, mid and treble alignments and in particular reflex and sealed box. With the latter the bass is quite well damped so some loss of extension/level is inevitable from 25 to 35Hz in-room but in practice is not too disconcerting.

Familiar music , classical jazz and pop, with good bas pattern timing, as judged on the Denon Reference AH 7000 headphones was not well resolved with the reflex alignment and the usual mental adjustment was required to make sense of the extreme low frequency timing and syncopation.

Regardless, this standard was quite high in a review context.

However the realigned IB version though 1.5dB less sensitive overall showed an unexpected turn of speed in the bass and the timing precision and resolution of complex syncopation was substantially closer to that heard on the reference cans.

In addition I concede that I have historically underestimated the high level of listener satisfaction such ability engenders.

In addition it is as if an important level of time smear and information masking has been stripped from the low range reproduction, from about 300 Hz to 30Hz

It would be useful to have listening reports from those few sealed box users out there.
