Sealed dual LMS 18" 5400 build - Page 2

The decision regarding how many subs is best made after you have measured the room and you only need one sub to do it. One sub in the listening position, moving the mic all over the place with REW. Paying special attention to the dips so that once certain positions are combined, the dips are taken out. That can give you useful data to help you decide. In a difficult room, more than 1 or 2 may be needed. In other rooms you might not find more very useful and you can then start putting multiple drivers in each box or whatever floats your boat.

Here is an example with just some mains + 2 corner subs overlapped:



Turns out in my room, two corner subs are slightly better than one and with the mains running down into the midbass a little I get a pretty good result. More subs in different spots don't help much. You might have a bigger room and more options, so the situation could be completely different. The key is to find out for your room then you are in a much better position to decide.

Sweet! Stock fans?

DAMN! That is a fine looking piece of gear!

Gettin close!

That looks familiar

should get a nailgun

I hope you used Titebond II.. to mate the surfaces of the box... PL is for the bracing....

I'd use PL over titebond, that stuff is invincible, and it expands.

PL is fine for sealing... but it will fail as a strictly wood glue... you don't see carpenters using that stuff...

What are your plans for finish? What can you do protect the driver cones if you have kids? I guess you can make a beefy grill how do you keep a homemade grill from rattling?

Looking good so far though

That looks great.... it will look better if you weren't using a cheap a$$ camera..

Not correct. PL Premium especially is some of the best glue for wood that is available. It is also very good for for MDF and end grain because it is not water based so it will not wick.

The downsides are that it is pricey and hard to clean up. I have used it without gloves and had it on my had for several days.

LOL


Nice work there buddy...

Its been a while since I made sawdust - I'm getting the itch again...


Get some good heavy duty magnets and sink them for a magnetic grill before you do the finish work - if your doing grills that is.... Not a big fan of grills myself, and little ones don't really like to mess with the big monsterous vibrating cones all that much...

Best idea for that is - after you finish building them and get them dialed in, tell the kids to get a close up look at them and then send out some test tones - you'll freak em out so as to never really have to worry about them messing with them.... Does that make me evil...

What are you talking about? My friend is a carpenter and loves the stuff. If you PL two 2x4's together, they'll break before the PL gives.

Yeah 2x4"s... No woodworker will ever use PL... You don't build furniture or kitchen cabinets with PL... I am surprised at you guys...

maybe no Canadian woodworker... lol..

There are pluses and minus, although I would really like to see some pull test done pl vs titebond.

I have my suspicions that pl would kick the snot out of titebond.

I think that "woodworkers" may choose titebond due to the ease of cleanup, rather than strength..

You can't mate two pieces of maple with PL.. Pl needs a cushion...

Pl is a construction adhesive ... rough construction like plywood boxes..
