Default W8-1772 build

I put the pictures in the showcase area, but figured I might post here as well.

Just (almost) finished a pair of W8-1772 following Bob Brines' design. Need to do some finishing touches, mostly the trims. Haven't decided on the style nor color.

I added some color to the "inner" box, to fit and blend with the living room, hoping to induce a higher WAF. Seems to work!

The boxes were a bit bigger then what my wife was hoping for, but the combination of color and wood made them pass the test!

I've been breaking in the drivers for some time, and finishing to do so while they are mounted on the enclosures. I like them a lot, so far.

Haven't pushed them yet, but they seem really nice and precise. I can't wait to try them with some known recordings and compare.

I'm usually using a computer for my music, so the BSC is going to be handled by an EQ.

Just curious why people use the 1772 rather than the 1808 for ported designs? Otherwise, your speakers look great and I'm glad your wife accepted them.

Basically from reading on threads here, looking at how the 1772 was well regarded. I did a horn for a 740Q and figured I didn't want to rack my brain on these... plus didn't have the time... so I went the easy route with plans already laid up. I was hoping to have sound before Xmas, and I did!

Also, the 1772 was the one available directly from the company.

I actually didn't know so much about the 1808 until after I had already bought the 1772. Maybe one day, the 1772 will end up in a karlsonator or something else, but for now, I plan on enjoying these the way they are now!

Thanks for looking and the comment!

why not? Qts is ok for port cabs. I think 1808 have too big xmax for fast fullrange speaker. I prefer 1mm.

They look great, and I've long considered getting a pair for a folded horn or similar.

I agree with methodarn - the real qts of 1772 is higher than spec, lays in vented box range and will often be modified higher yet by significant source Z of low negative feedback amps used in this hobby. 3mm is too much xmax - wastes flux and sensitivity plus invites "gargle" . FE206E can develop more usable impact. 1772 is well damped for a fullrange and sounds more like a competent 2-way than some fullrange drivers. I do better overall with good 12 inch coaxial as less power is required.

I rather like these drivers.

Can't remember which I've heard now, but, with a floor-standing ML-TL, they're the closest to full-range I've heard from a single voice coil.
I'd take 3mm Xmax over 0.5mm every time - its nice to have headroom. Sensitivity is high enough for a couple of watts to make quite a lot of noise.

The only problem for me is the price.

Chris

The 1808 requires a rather larger cabinet in comparison to the 1772. My MLTL for the 1772 is 70l and 40" tall. For the 1808 it would be 100l and 48" tall.
