Pictures of my new range of speakers

I've just posted the first pictures of my new range, featuring a full-range speaker and two different subwoofers:

new range of speakers

I'll be adding more pictures and technical details to my web site for those interested.

My thanks to all those on this forum who have contributed to the discussions that have helped me get these speakers designed and built.

How much did it cost to make them? And do they sound good?

Well, they were expensive to make because I had them built from CNC routed MDF slices. Later I will explain more on the web site but, for now, I have some construction photos here.

As for your second question ...
I think that they sound wonderful - but then I would, wouldn't I?

Another "Translam"....

nicely built speaker, well finished, wish I could hear it !

Please send a pair, all expenses paid, to Down-Under-Land ;-))
(or turn them up real loud !!!)

that method of slices of mdf sure does eliminate cabinet resonances, doesn't it !!!!

I will shortly be putting together a few web pages on "curved sides loudspeaker construction", would it be ok if I used one of your pics as one of the examples of the horizontal slice method??

Yes of course. Please credit Seventh Veil Loudspeakers and, if possible, give a link to www.seventh-veil.com.

Thanks for your nice words.

Are those all running full-range or are they splitting duties?

The 'Awesome' subs have a low pass filter and this is set at 100Hz which gives flexibility in room placement - at 100Hz with a reasonably steep slope they disappear. I have been using an active filter for this but will test a passive to see how it compares. Any comments on active v passive for subs, anyone?

My original plan was to cut off the full-range 'Nonsuch' speakers at 100Hz. I thought that relieving the drivers of deep bass duty would give them higher power handling and could tidy them up. I have been using a passive line-level filter for this. However, I've also run the full-range speakers without any crossover - active, line-level or passive and I prefer it. The sound is even clearer than with the line-level passive in circuit and there is no evidence that the drivers need any relief from sub-100Hz duty. The power handling seems unaffected - they still play more than loud enough for most people's tastes.

I had thought that, as I was going the crossover route, I might as well add a little diffraction compensation (switchable) into the circuit. Having listened extensively to the speakers, I'm now of the view that this may cause more problems than it solves.

There's no doubt that putting anything into the 'Nonsuch' speakers' circuit - either line-level active, passive or, heaven forbid, between the power amps and speakers, adds another 'veil' to the sound and that's not what my designs are about. I'm waiting for an active crossover unit with diffraction compensation to be built for me. When it arrives I will give it a thorough listen but I think I'm leaning towards the 'purist' route.

I'll bet you got more than you bargained for with that question.

Thanks for asking.

In that case coming with a name Seventh Veil Loudspeakers is slightly misleading as your intention is to remove all the veils from your speakers (joke😉)

I also noticed, after some experimentation, that removing whatever is not completely necessary in the speaker's crossover, usually improves the sound.
 
Hi,

I also noticed, after some experimentation, that removing whatever is not completely necessary in the speaker's crossover, usually improves the sound.

Not that I want to speak for Steve here but the whole idea of the 7th veil is precisely that: removing it.

I recall the first product from day one from reading about it in some British mag.

After dwelling in hi-fi circles for way too long I feel that going back to simple, if not perfect solutions aren't such a bad thing.

That is, if music matters to you of course,😉

Now I get it, it's not Seven Veils, but Seventh Veil. That makes sense. Sorry for not getting it the first time.😉

Yup, you got it Peter but just to clarify and for the record ....

Any speaker puts veils between the music and the listener. The goal is to remove as many veils as possible. I believe that in "The Dance of The Seven Veils", the seventh veil was the last. Hence the name.

PS: Wow Frank - some memory!
 
Paulinator, to try to clarify further ...

The preamplifiers that I use have two outputs.

The first output goes directly to the power amplifier (stereo) that drives the Nonsuch 4 floorstanding full-range speakers.

The second output goes to a valve (tube) crossover unit which is a low-pass filter (18dB/octave) acting at 100Hz. From the crossover unit the signal goes to a second power amplifier (mono or stereo) which drives one or two subwoofers.

I have been using (at the Frankfurt Show) EAR power amplifiers (70W per channel, class A) the same for the full-range as for the subwoofers. I would imagine that this isn't necessary and I could use solid-state power amps that were not identical to the "full-range amps".

I could supply power amplifiers with the subs but, at the moment, am offering customers the option of choosing their own. These needn't be expensive and at home I will probably be using used Crimson monoblocks that I bought on eBay at a very good price.

I hope that this clarifies for you. Thanks for your question.

I just can't wait to hear them.
Is the offer still on for a demonstration with my 845 amp? Looks like I'll have to get a move on!

Absolutely. I've followed the saga of your 845 with interest and really look forward to hearing them with my new babies. I'd love to hear the Nonsuch 4 go 'single ended' but think most SE amps don't quite have the power for them.

As soon as you're ready, we'll arrange a time and place.

Alert the media.
