Hi Bob

I've just stuck the supra baffles with silicone. How long do you wait before mounting the drivers.

I had a bit of a set back due to dust falling on to the wet paint, so annoying!! But after a light sanding and respray they look fine

Last question, I hope!

Bob suggested inserting a stiff cardboard tube into the port before committing to the standard 4” plastic tube.

How does the length of the tube effect the sound?

Thanks

Richard

The longer the port the lower the tuning

Thanks Dave

The speakers are complete! but the silicone manufacturer says the sealant will take 24 hours for 1.5mm of silicone to dry. He also said the silicone might not adhere to the supra baffles because the MDF isn't primed...argh!!

Oh well, I better not stand the speakers up until tomorrow morning

On the little red boxes, the veneer was paper back quarter cut white oak, stain was industrial alcohol based dark pigmented named "Port Mahogany".

On the micro-towers, the veneer was paper backed cherry, stain was ML Campbell Woodsong WS26124 Cinnamon.

On both, the top coat was ML Campbell Magnamax pre catalyzed Nitro cellulose lacquer (25 degree sheen, 4 coats, hand sanded between)

The cherry's pores are quite easily filled by the 3rd or 4th coat, the oak still retains much of the pore texture. One client had requested oak grain to be fully filled with water based polyurethane - it took at least 6 spray coats and looked like cheap plastic laminate.


Even if your layup skills are up to the challenge of working with contact cements, avoid solvent based adhesives on paper or wood backed veneers when the product will be finished with solvent based stains or top coats.

The day that I have been waiting for, and I'm far from disappointed!

The speakers actually sounded surprisingly good from the start (not as thin, boxy and screechy as I was expecting) and and over the last four to five hours the bass has developed significantly. I've tried a variety of music and it sounds good with most easy going genres.

I really must thank Bob, you've been a great help and I thoroughly recommend your speaker instructions, very clear and easy to follow.

If you are looking for a relativity simple build, not too large and something the wife would like, it should defiantly be on your short list!

I've taken lots of photos during the build and if anyone is interested I'll be happy to upload them.

I'll post further information as the drivers break-in.

Richard

The cone movement was due to a slightly high dc offset during powering on and off...all is well with the chipamp.

Is the port supposed to be pulled out like that? It looks like it is pulled out of the hole like 1/2".
