This was the thread where they were basically started as LLT's:

All I did to convert them to DO is pull the port out and shorten the enclosure and build a new endcap to house the second woofer, it was pretty easy smile.gif

Oh, and for the base and feet, I literally got 8 huge lag screws that you usually see holding decks on to the sides of houses, and 8 4" spacers that the lag screws pass through the middle of them and screw into the bottom platform.
post #1863 of 2212
Thanks all.

Headed out to pick up two 3' x 24" tubes and two 1.5' x 24" tubes. Total ... 122.00. biggrin.gif

Now I need to find someone to cut the circles, or buy a router. I don't have a garage, well I do but its a gym. I cant believe how inexpensive this is, and how well they will fit in my space.

How much space needs to be between the down firing woofer and the base plate or ground?

6 -8 inches is usually enough

That will work perfect, just give the driver at least 4 inches or so.

LOL! I'd like to go with as least amount possible. So.... is four doable is it more like 6-8?

I forget, do you get more DB ( I know very minor but none the less) with or without the base plate? I'm on concrete slab with pad and carpet.
post #1868 of 2212
my baseplate is 4 inches, and it works perfect. you gain like 1/2dB or something adding the baseplate so the difference is minimal enough you need not worry about it.
post #1869 of 2212
So beast.... Couple questions.

1) how much does your top baffle over hang the tube? I think you said they were 27" but im not sure how big your tubes are.

2) you say quad 18s. Assuming but want to double check. Thats two per tube right??

Look where i just came from! biggrin.gif Two 3 footers for dual opposed and two 1.5 footers for singles to smooth out the FR.

Long day..... finally back at the office.

With two dual opposed cabinets and two single cabinets I'm thinking it might be best to go with two separate amps. Does anyone have any other ideas?

No matter how I configure it unless I take one driver from a dual opposed and connect it with the two separate drivers on the other side of the room I don't get an even load from a single amp.
post #1871 of 2212
I would use two separate amps since you are spreading them out. I built 8 sealed sonos before.

Ya I'm not seeing any other real 'good' way to do it. Crown has the 1500 and 2500. Definitely open to suggestions.

I was at a speaker store the other day and they brought up Crest amps. I've yet to research them.

I couldn't resist. For 110.00 I just got enclosures for 6 18" woofers. Already have the mini-dsp, the MDF, the dowls.... did I mention 110.00 for enclosures? eek.gif

EDIT--- Think I'm going to treat myself to a router and whatever it takes to cut circles!

Cool! Might you start your own thread.. Plenty of us will be glad to help you out. cool.gif

Yip! that's what it takes and a jig, that can be made though.

It's on the list. 8:02 PST and I'm sending out comps and drawing up paperwork. Guess I'm being paid back for two weeks of 'down' time. smile.gif

That is exactly what I need. But it's too small. I need something that will cut at least 25". Thanks though as I'm sure there are exact models that go bigger.

You can also make one (adjustable) for a few dollars if you’re inclined? Take a few lengths of 1/8” and put two running slots in each one and then wing nuts.

OK on amps, the crests are a good option. Right now I am currently running 4 si's wired to 4ohm per channel of a peavey 7500ipr2 you could literally buy one epx4000 or ep4000 per pair of drivers, or even the new Beringer 4 channel I nuke. Also, wiring 6 drivers, three per channel on the peavey would actually be almost perfect. If you can figure out the wiring.

If I wired three per channel then Id have a third driver on the opposite side of the room of the dual opposed enclosure. That would make eq ing the single enclosure frequency smoothing or near field subs impossible.
post #1885 of 2212
OK then. Wire the two dual opposed boxes to a single 4 ohm load, and the two singles to an 8 ohm load, 4 on one channel of the peavey and the nearfields on the other. Yes they are at a lower impedance but with just two, the power will still be about t the same as each sub is getting on the other channel in 4 ohm

Gotcha.... it is OK to use the same amp wired in stereo and use each channel , one for near field and the other for the dual opposed. I could use the cv500 in the same way with 4 ohm/2ohm load configuration.
post #1887 of 2212
The gains will be different, and on the CV I don't know if the channels are fully discreet, but on the peavey they are.
post #1888 of 2212
Yes, the gains. Thats not an issue though right?

Im really liking the peavy 7500 and the way it breaks down giving my drivers all ~ 1000 wats.
post #1889 of 2212
Nope, you should be good there.

Cool thanks.

You were going to try the amp in 4ohm mode and give your impressions over in Gorillas peavy amp thread. Did you ever get it hooked up with a 4 ohm load?
