Sorry, just realised that I didn't answer your question, and the answer is ... try it both ways and see what works.

Where are you crossing over to the subs? 120hz was the suggested place but try 80hz instead (the 3x3 has plenty of low end)

when does Oxford arrive at this train?

Hello,

I am using an Apogee system consists of 4 3x3s2 and 4 AE-15 with
Apogee Pocessors and 8 DA-800 amplifiers. In my opinion this is a great sounding system.

I think 4 3x3s2 with 4 AE-12 is a good system.
You need many subwoofers as 3x3s2 is a powerful loudspeaker.
My suggestion is when you will service the drivers you must use Apogee original spare parts.
All Apogee drivers are Ferrofluid treated.

Here are the models of original Apogee spare parts:

3x3s2 Replacement drivers:
1" HF: 110-142-B
2" MF: 110-12-B
15" LF: 110-06-B

3x3s2 Diaphragms-Recone kits:
1" HF: 110-142-D
2" MF: 110-12-D
15" LF: 110-06-R

You can contact with Apogee directly for the availability and prices.

Stavros Triantafilou

Thank you everyone!

Ok, I'm going in today to test drivers, etc...

Any tips on quickly testing drivers, phase,etc...(i have 8 3x3's to work out!)

Also, is it best to remove the grill or open the back of the 3x3's?

Lastly, how do I know if I need new Ferrofluid? If so, what is the recommended procedure?

Thank you all again!

You must remove the grill to check the HF driver and the back panel to check the MF and LF driver.

You can ask Apogee about Ferrofluid. I think that there is a bottle with Ferrofluid in each Apogee Recone Kit box but I am not sure.

About the phase, you must check that all the cable you are using, are correctly soldered and the connection between the processor and the amplifiers are correct.

You can check the phase of the loudspeaker drivers with a phase meter, there are many analyzers that have phase meter.

Regards!

Thanks Everyone for the tips!

Made some changes with the array and I put 2 3x3's arrayed 60 degrees and 2 AE-12's per side.

Sounding much better!

Any idea how I can attached a array plate or bar using the top array holes to fix the 60 degree angle.

Thanks for any help!

Google for Apogee MARS frames and couplers, I've seen them on ebay, splay couplers were made at various angles. Please note that the MARS frame adds about 80lbs to the (already unwieldy) 3x3.

Hi Ian,

Thanks!

Do you think I could DIY a splay coupler?

Maybe some 3/4" baltic birch,etc...

Or, fabricate a couple pieces of metal?

probably, do your 3x3 have aeroquip or nutplate connectors? if nutplate it shouldnt be difficult to make a spacer with the correct angle and attach it to the cabinet. if they are aeroquip be prepared to spend a lot on connectors!!

Looks like null plates.

I was thinking 2 "bars".
One to attach the rear inside corners together and the other to attach the front inside corners (null plates).

OR do you think I should aproach it using something else?

Null plates? I assume you mean nut plates (circular metal plate with a threaded hole in the middle) but 2 bars as you described should work well

Sure. Two bars per pair of speakers will work fine. You don't need the MARS stuff because these bars aren't being used in a critical application such as hanging the speakers. All you're doing is holding a certain distance between the front grilles; the speakers's weight is on wheels on the stage. Any reasonably sturdy bar stock will suffice. Wood or metal or plastic.
