X-SLS Encore build
« on: 12 Jul 2019, 06:08 am »
I'm working on a pair of X-SLS Encores. This is the floor standing version of the X-LS Encore. They're getting upgraded crossovers with Sonicaps, Mills resistors, and Miflex KPCU by-pass caps.

Here's some pics of the build so far:

Parts cut and location of dados marked out. Normally I don't go to the effort of cutting dados for just one pair of speakers but they make it a lot easier to glue the cabinet up square.




Rabbets and dados cut




Cutting out and rounding over the internal braces








Gluing up the braces, sides, and rear baffle








Installing the No-Rez. The last two pics are of the No-Rez that will be attached to the front baffle. It's a lot easier to put it in before gluing the baffle on.









Gluing up the front baffle




Flush trimming the baffles




3/4" roundovers on the front and rear baffles and 3/8" roundovers on the top and bottom




Laying out for threaded inserts on the bottoms




Driver openings cut and a roundunder bit to put the roundovers on the back side of the woofer holes




After that it has been sanding. To start with I used a random orbital sander and profile blocks to hand sand the roundovers. Normally I am working with wood or wood veneer. That does not require a super flat surface so at this point the prep sanding would be done. However, these are going to be painted a satin black so I need a much flatter surface. I borrowed Jeff's ideas from his X-MTM Encore build and ordered in some long Dura-Block sanding blocks (16", 24", and 30"), sandpaper rolls, and powder guide coat to get the cabinets as flat as I can before spraying the primer. I'll be using Target coatings water borne EMTECH primer/surfacer/filler, black pigmented lacquer, and a satin lacquer topcoat.

The Dura-Blocks, sandpaper, and powder guide coat arrived today. Now the tedious part begins... sanding, sanding, sanding, some more sanding, and oh yeah, sanding......

For those of us not as familiar with the GR line, which one is this ? I don’t see this on the site.
What does it look like complete?
Thank you.

Scroll down the page and you'll see plans for the floor standing version. http://gr-research.com/x-lsencorekit.aspx

The X-SLS version includes floor spikes and additional wiring.

That's awesome Mike!

I would certainly like to hear your opinion on the Dura Blocks and the guide coat after you've had a chance to use them.     Just to clarify from my build, I only used the guide coat on the BIN shellac primer I used to seal them and not on the raw MDF.      I'm also curious how those super long blocks work out for you.    The set I got topped out at 16" which is what I used.

Can't wait to see your final results.

Hi Mike, We haven't gotten any updates on this build in a while.   Any progress on your X-SLS Encores ?

Jmitchell3 - Thanks.   The short answer is persistence.    I documented my painting process in this build thread:

I got them up to the point of spraying the primer/sealer at the end of July. I was stuck at that point for almost the entire month of August. I don't have a climate controlled spray booth or area. Instead, I have to set up an EZ-Up canopy with sidewalls in my driveway. This means I can't spray when it's raining. Normally this would not be a problem. In the past I'd set up the canopy in early June and not have to take it down until mid September because we always had droughts in the summer, floods in April/May, storms in September but nothing in between. This summer has been different, especially August. It has rained every week this month. Not everyday mind you, just the weekends. It's like the weather knew I have to travel for my day job during the week so it rained on the weekends. When did weather learn how to read a calendar  :dunno: ?

The pattern held this week too but I only had to travel one day, today. I was able to get the spray booth set up on Monday and start spraying on Tuesday. I had some problems at first with the primer, it's a new product I was unfamiliar with, and with a new spray gun. I ended up having to sand off what I applied on Tuesday and start over on Wednesday. I got three coats of primer on but am probably going to need at least three or four more before I'm ready to spray the black pigmented lacquer. More storms came through last night and today so I had to take the spray booth down to keep it from being turned into a pretzel. The rain is supposed to be gone for a few days so I'll set the booth up again in the morning and get back to it.

To add insult to injury (or just envy) my next door neighbor started pouring the foundation for a large workshop in his backyard....
