Homemade speakers – the Riders get baffled in Horsham

Posted by: David Hobbs-Mallyon on 31 January 2003

Following the thoroughly enjoyable, but unduly restrained trip to Tom Alves a couple of weeks back, the Riders were looking forward to our next trip where neighbourly wars wouldn’t play havoc with the volume knob. Fortunately for us, RichardN came to the rescue, with an invite to come for a listen to his sistem. Richard lives well off the beaten track with neighbours well out of view, never mind earshot. MrsN must have also had a tip-off about the Rammstein, as she decided to make herself scarce for the evening.

Richard’s sistem consists of an LP12/Lingo (with the ‘Weekes’ modification)/Ekos I with a retipped Troika and also a CDX at the front end. Amplification was provided by an 82/HiCap/250. All the equipment sits on an Ash stand in quite a large room which is probably near perfect in proportions. However, what really was of particular interest was for us to see and hear the DIY speakers that Richard has been working on.

Prior to arriving, Richard had described them to me as a home designed and built loudspeaker with infinite baffle of Linn Tukan proportions. What I was not expecting was the sheer quality of the build and finish – these certainly did not look like one of my DIY isolation platform projects. The speakers were on Kan II stands sited close to the wall. The finish was at least up to the standard of most commercial loudspeaker manufacturers – perhaps the only thing to give these away as homemade was the fact that Richard had kept the crossovers in separate boxes outside of the loudspeaker cabinet at the base of the stands – something that must provide better results. Examining a spare pair of the speaker cabinets showed the build quality to be superb – really heavy beasts for their size. In making his own speakers, Richard was able to use the best quality drivers he could get his hands on for the cabinets. Using the best quality components certainly has sonic benefits, but it does push up the cost significantly above the ‘entry level’ price range.

So what did the speakers and the rest of the sistem sound like? Where the sistem really excelled was in the PRaT, dynamics and detail. The sistem delivered an excellent rendition of our Rammstein ‘test’ track with some real attack – these are fun speakers. This is the second time, I’ve recently heard a set up with 82/Hicap/250 recently – a set-up I never really got to be comfortable with in my own sistem, but it was undoubtedly doing the business, so I think I’m going to have to re-evaluate my opinion of this combination. Part of this is I’m sure a real synergy between the amplification and the speakers. Whilst the speakers didn’t produce that much depth in the soundstage, I never found this to be something that was important – basically a true flat-earth design. It was also surprising for all of us to hear the amount of bass they did for their relatively modest size.

Coming on to the front end, there was one more component that is an essential part of Richard’s sistem, and that is his Moth II record cleaner. A comparison of a before and after of one of the records that Dave J brought along, demonstrated a real clearing-up of a whole layer of grain. If you like to hear your snap, crackle and pops at their clearest, then this noisy beast is well worth it from what I heard. Certainly this all helped in making the LP12 the superior source to the CDX on the night. However, even the combined forces of LP12 and the Moth II failed to make Richard’s copy of ‘Alessandro Moreschi - The Last Castrati’ bearable – a painful record to listen to in every way imaginable. In terms of shock value, this performance of a 2nd rate castrati well past his prime only managed 3rd place for the evening. 2nd place went to Tom’s Glastonbury recollections of a Hawkwind concert. 1st place went to the yellow jump suit on the cover of one of Richard’s Max Webster records – undoubtedly a design encouraged by the 12 inch medium. I think I’m starting to get my head round at least the differences between the sound of an Aro and Linn type arms on an LP12. For me I find myself leaning more in the direction of a preference for the Aro, although I know Dave J will put this down to my familiarity with the CDSII.

For me there was one negative of the sistem - whilst the speakers could go down low, there was sometimes a lack of weight in the lower mid-range to upper bass. The effect of this was sometimes an overall lightness to the presentation where the tonal qualities didn’t seem quite right. Part of this was undoubtedly down to the room which had recently had the carpet replaced with a wooden floor. My suspicion is that some if this is also down to the speaker crossover – I know that Richard is working on a new design that promises even better results. He is even talking about developing a carbon fibre design if he can get a few other people interested in the project as well.

So, many thanks to Richard for inviting the four of us round, and for keeping us suitably fed and watered – very much appreciated. As usual, I’ll write some more on the music when Nick supplies the track listing.

You have cats? So Tom doesn't have the magic touch.

And prey tell, what Max do you have?
I thought they were pretty much unknown outside of Canada.

Any pictures of the home-made beasties....I have not seen them since the development phase.

Horsham is indeed a baffling place. A bunch of us once made the front page of the local rag there, just by doing trials tricks on our MTBs in around the town centre. The headline was 'Hooligan Cyclists'. If the Advertiser ever started selling back issues, I would definitely get t-shirts made up.

Saw Max Webster once thank god Rush came on after.

Funny lot in Horsham Wink

Hove actually!
Great bakery in Southwater.
RSPCA building is very impressive.

If anything, Southwater is even more Royston Vasey. Still, decent bike shop, and usefully close to the Downslink.

I can't talk about Crawley, just thinking about the place makes me depressed.

Hove is now a borough of London. I believe there may be a bylaw that requires the wearing of Helmut Lang trousers anywhere west of Seven Dials. I've not risked going over there since it became illegal not to sport a Hoxton crop.

Crawley ain't as bad as most people think (its much worse). No, if you keep out of the "no go" area's between 12 at night and midnight your OK. Wink
I detect bit of Londonism in your post, guess where I came from?
Where are you from?

Howard, for my sins, I spent most of my formative years in Horsham.

Some comments about the tracks.

Ella Fitzgerald/De-Phazz – “Verve Remixed” - Wait 'Till You See Him
Sounded really good on Richard’s sistem . Really enjoying this album at the moment.

Joseph Haydn - Kyrie from 'Theresienmesse' - English Concert/Pinnock
Saw this with the same performers at the Proms a few years ago – on my sistem, the recording just doesn’t live up to what I remember of the live event– doesn’t on Richard’s either. Still worth having though.

Anton Webern - Funeral March from Six Pieces Op 6. - Yuasa/Ulster Orchestra
Actually a very good piece, and an excellent recording from Naxos. Richard’s sistem coped admirably.

John McLaughlin – “Extrapolation” - Binky's Beam
Excellent track – sounded really good.

Yello "Live at the Roxy NY Dec '83" Single sided vinyl. "Sounds a bit like Rammstein..."
I think I made the comment about the Rammstein – superb.

Alkan, "Mad Woman.. and Comme La Vente" Two very different pieces by the same composer.
Hmmmm. First piece was interesting, other was VERY different. Not convinced – need to hear more.

Hawkwind – “Stonehenge Do Not Panic - Live 1984” - Shot down in the Night because I was there man
Suitably brutal - need to hear more of this.

Craig Armstrong "Weather Storm"
Excellent – if it’s the track I remember. Lots for the sistem to cope with, which it did admirably.

Chaka Khan – “What Cha Gonna Do For Me” - Night in Tunisia
OK, it’s Charlie Parker next time…..

John Patitucci "On the Corner" On The Corner
Another dodgy LP cover

Neil Young – “Decade” – Like A Hurricane
It was odd that this sounded dull – white label vinyl (???) as well. I’ll stick to my CD until proven otherwise.

Jacques Loussier – “Pulsion” – Soupir
Did I say crap? I'm sure I was less subtle than that. I hope this wasn’t why Nick decided to leave at this point?

With apologies

I've been utterly snowed under with work so have been unable to add my comments to what was the main focus of attention: Richard's speakers.

The expression 'home-made' can often give the wrong impression but in this case, Richard has clearly put an awful lot of time and effort into producing an exceptionally professional looking product. I was particularly intrigued with the self imposed limitations of using a Kan-sized enclosure, which in this case has worked remarkably well. Bass was surprisingly good for such a tiny speaker, no doubt the use of top notch (and very expensive) Scanspeak drive units has helped.

The possible limitations of a compromised cross being a minor criticism, the speakers did major on dynamics and pace and coped very well with some fiendishly difficult source material. The cones hitting the bumpstops on Rammstein was something I haven't seen for a while!

I'm pleased to hear that the new room placement is working well. We mentioned on the evening that re-positioning the equipment stand from between the speakers would be a good idea and that it would be a very good idea to get the LP12 off the all-in-one Ash stand altogether, did you manage to do this at the same time, Richard? If so has this had a big impact?

Thanks for the hospitality.

Richard,

I think you need to get some pictures of the speakers up on the forum.

BTW, what sort of design were you considering for a carbon fibre speaker?

There's an article in the February/March edition of 'Race Tech' magazine by a chap who's building a racing car from aluminium honeycomb.

This material would appear to have some similar superficial benefits to carbon/Kevlar except that it can be routed and folded/glued up into boxes. The chap referenced above seems to be using a woodworking tool for this.

I remember Celestion having trouble manufacturing consistent SL600s, but they were starting from the wrong place...

Think a sealed box version of a Wilson Benesch with the same internal volume of the Kan.

What shape were you thinking of?
