Just listening to these at Colin's - my cunning plan is to get up really early in the morning and steal them while he's still asleep!

Seriously, tho they are the closest thing I have heard to Quad63 but without the 2 ohm load hassle, they have amazing speed and focus; I like these a lot, they suit my tastes and work nicely with 300B power.

Its like having a pair of headphones but in the room.

We plan to compare them to his Rossendale floorstanders later, I'll get a idea if they lack bass then, but right now I could be convinced that they don't, its so tight and fast, perhaps a little recessed. Colin has them running with just a touch of T90A super tweeter, through a very small cap, the effect is very subtle but just takes off some of the driver's inherent dryness. I could live with them either way....

I'm curious as to how they will perform in the Pencil design.

In terms of a 2-way, the challenge will be finding a suitable bass driver to match these lightening fast drivers, stunning design work Mark et al.

Colin's choice of veneer? Well let just say, the photo doesn't do it justice...

Andrew

As to the actual veneer these will be skinned, in I have taken a close up photo of one the actaul leaves I have. To remind folk this is radial saw cut birch burr and each leave measures 237cm x 70cm That's 93 inches x 27 inches for you non metric folk and costs 35/m (UKP). It is nice and flat and quite flexible. I don't see any issues with using this veneer it looks and feels very nice indeed. The photo don't do justice really and the colour in real life is a little richer than the photo suggests. But hey I'm no David bailey with a camera.

My mate Andrew left for for home this morning and didn't steal the speakers as threatened. However, the plan is, with the aid of Scottmoose, to design him a floorstanding cabinet with some bass helper(s). So watch this space, for developments of this design.

Here's something different to think about: Surreal Sound Audio - Home TangBand 8" fullrange driver claimed 20K down to 100hz crossed to six stacked downward firing 10" woofers per channel. I believe it's called a push pull triple chamber bandpass enclosure with two woofers/channel, chamber #1/driver firing into a vented chamber #2/2nd driver firing into the third chamber. Never saw it done with six drivers, three and three oriented parallel to each other all six chambers vented.

Unfortunately no.

The start of a new full time job, back to work as a Civil Engineer after a near 3 year semi-retirement with a long commute means I now only have the weekends spare. However, Scottmoose is coming over today to spend some time listening to his design and a couple others and it's Bank Holiday weekend here in the UK so hopefully I can make a start veneering them tomorrow (Sunday).

Cool man, congrats on the new job! I know how it is to work full time and be limited to a few hours on the weekend to work on projects. In any case, I hope the listening session went well and Scott can chime in with his impressions. I'd still love to get those enclosure dimensions and porting so I can build a pair for myself.


Cheers,
Steven

Steve, If you contact Scott direct he'll give you the info. for a personal build. I do know he has had issues recieving emails of late so be patient.

Scott went home with a very favourable impression and a broad grin of these speakers so I expect he'll post up something in the next few days when he has collected all his thoughts together.

I've been looking at this one as well

I imagine the imaging would be even better than the pensil designs.

Yeah I shot him an email on Friday regarding this enclosure while at the office. I sure hope he answered

Vaughn, I have the same thoughts. I'd imagine it images better and has a more delicate presentation. Can't wait especially since I just built a new subwoofer (CSS SDX10 & Apex Sr. plate amp) which should help tremendously to augment any lost low end. I'll also be using my Electra-Print PVA and crossing them over at 70hz.
