Nice Steve. Chris choose a similar veneer for the FH3 we are currently doing.

Steve,

What are you using for damping? Can you share some pictures of the stuffing?

Thx, Zia

well the supplier shipped the wrong product twice, so it's not exactly a true ribbon-grain, but will be fine

takes longer to apply the veneer and inlay solid edging for chamfers than to assemble the cabinets (discounting glue drying )

stained that nice dark port colour with lacquer finish to follow in the next couple of days


BTW folks, if you're planning on burying your magnets for grilles, do it before assembling the boxes -it that was fun jigging up on the drill press - found yet another way to use "carpenter" app in my iPhone



Dave took some photos of an assembly mock up of the FH3 a week or so ago, including damping schemes for different drivers. In his spare time, he'll probably get around to updating the FH site or the vendor's thread here.

nudge - nudge

Nice work Steve. Chris, have you ever used 1" thick ceiling tiles to line the box. Would this eliminate need for stuffing?

nope

my intuition is that neither standard Fibreglass, or the cellulose fiber based that I've seen would be quite right, but it couldn't hurt to experiment - provided it's accessible to replace

And less time to assemble than to pack for shipping.

Lining boxes can remove the requirement for stuffing, but it depends on the box in question & its alignment. In the case of the Pencils, which are a TL variation in terms of their approaching ~flat impedance, the stuffing is needed.

Thanks Scott for the specifics. I am still thoroughly enjoying my Pensils. For an easy introduction into FR enclosures, it sure does sound good. Building an F3 with a little more power to see hoe they sound together. Sorry for the hijack!

Thanks for the comments guys, it was a fun and rewarding project.

Zia, I'm using a touch over 1.5lbs per cabinet of genuine Poly-fil. I ended up going to a local hobby store and snatching some up about 6lbs for right over $13 USD. Steal of a deal compared to online stores selling it for much more per pound.

Chrisb, Fortunately I don't foresee the need for speaker grills on these cabinets due to the limited amount of people I have over, as well as the strict rules my girlfriend understands about my listening room. Plus I absolutely love the copper/gold-ish color of the cones.

The speakers sure do sound great and I think I got the amount of stuffing spot on so I'll permanently seal them up in a couple of days. I think my amplifier and this speaker combination work real well together, providing a nice smooth and relaxing sound. Though, I plan to step it up a bit to the higher end of amplification and see what kind of detail I can really pull out of these things. I'm also using the absolute worst rca's available to man kind (the free generic ones you get with new equipment) so that may be a slight limiting factor in regards to getting more of a sharpness in detail and presentation.

Overall, everything just sounds 'right' no shouting vocals, nice smooth warm sound that's very inviting and non-fatiguing.

Cheers,
Steven
