Re: Curved SLA depth

https://epson.com/epiqvision-ultra-ls500-laser-projection-tv I can see why this is a problematic configuration for the centre channel. But I guess my cure would be to build the SLA deeper, and then put the projector on top of it. Or put the SLA beside the projector. That shouldn't be so off-centre t...

Re: Passive Crossover questions

For any crossover steeper than 6dB/octave, you'll need to disconnect the drivers from the crossover. Otherwise, the amps will "see" the drivers in parallel with extra components, which may cause substantial problems.

Re: Replacing electronic parts

That's very likely not a potentiometer in the traditional sense, but rather a rotary encoder. They don't really have a value as such, but can be had cheaply: https://www.amazon.com/s?k=rotary+encod ... ush+button

Re: TITAN 48 in 89"

Just to clarify: 18" (inches) is 45.7 cm. 36" is 91.4 cm. You've got to keep your eyes on the units. If you bring up the SketchUp model, you can change the unit of measurement, but it does yield rather uneven numbers. I have found it easier to just get a steel ruler with inches on one side...

Re: Makita cordless circular saw (36v?)

A lot of the 36 volt tools will run on 18 volts with one battery, which keeps the weight down, albeit with less gusto. I recently purchased a Festool TSC 55 tracksaw which does just that. Yeah, it's pricey, but lovely. The included dust collection bag really works well, and that in combination with ...

Re: Makita cordless circular saw (36v?)

Do you in fact mean 18 volt, rather than 28 volt?

Anyway, I second Bill's opinion. 18 volt will be ample for cutting 1/2" plywood. Brushless gives you more per Ah, so that will make up a bit of the lower voltage.

Re: Plans in metric diamensions

I have two steel rulers that I bought at Hornbach here in Sweden. They are metric on one side and imperial on the other (with one edge with the usual fractions, and one with 1/10 & 1/20 divisions). The shorter is 60 cm / 24 inches, and the longer is 100 cm / 40 inches. I've used them a lot when ...

Re: PL vs. wood glue

I've become a huge fan of PL, using it for lots of other types of projects around the house too. However, I have a question. Is there any downside to using a good wood glue for some of the face to face joints? For instance, the woofer spacer to baffle (assuming no mesh), or some of the places speci...

Re: Type of plywood for THTLP

I looked at Sikabond-T2 iCure, but I doubt that it's the same stuff as PL Premium. There's no mention of expansion, which is a major benefit of PL Premium when building loudspeakers. I have ordered PL Premium from Speaker Hardware, and that worked well. I have also used Sikabond-545, which I suspect...

Re: Type of plywood for THTLP

My preferred source for anything plywood related in Sweden is Calexico Wood (http://www.calexicowood.se/). Great prices, and execllent service. They carry both 2440x1220 mm (8' x 4') and 1525x1525 mm (5' x 5'). They can deliver to your house, or you can pick it up. I happen to have an outlet nearby ...

Re: Simplexx 110 Build

When the ripped up finger was finally healed it didn't work right anymore, so what I used to fret with that finger I had to learn to fret with my pinky.

Then there's the question of how the glue will stick to that surface. My guess is not well at all.

Re: How do I reduce feedback

Ok I took the receiver home to do more testing. I opened up the unit and I powered it on. On the channel that is giving me problems the signal meter pegs when I tap on the circuit board. Other channel no movement. Does anyone know what I can look for that may be causing the issue? Or should I just ...

Re: Speakons; Just use the screws or solder them?

Tin the wires and use the supplied screws is what I do... Tinning is what can cause the screws to loosen. Bare copper deforms under pressure, allowing the screws the best possible grip. Tinned copper is too hard to deform under the pressure of the screw, so it doesn't grip as well. This. In some ca...
