Best way to calibrate two subs...

Arkive

Hey guys. I've finally made the plunge to upgrade my old Sony 5.1 and Yamaha receiver and settled on the VM30's for the front, VM20's for the back/center, and a pair of DSW MicroPro 2000's. I couldn't find a 3k or a 4k at a price that was even remotely as good as two 2k's off the Polk eBay store, so I went that route. I'm pairing these speakers with an Onkyo 608 receiver. So setup *should* be simple, but I'm guessing calibrating the two subs might be a little tricky. Any recommendations? For reference, I use my setup exclusively for HT and the room is about 17x25. Thanks!

Not sure what your budget is...

You could try the Behringer DEQ2496 along with their EMC8000 microphone. You would simply need a microphone cable and Y splitter if your current receiver only has .1 out. You would need RCA to XLR for the DEQ

You would go from the Y splitter into channel 1 and 2 of the DEQ2496 and apply filters, eq, phase/delay per channel.

Looking at ~$320

Place both subs where they are going to live. Run LFE to both subs using a Y adapter at the receiver end. Unplug one sub and calibrate with just one working. Once it's calibrated , un plug and calibrate the other sub. Once both subs are calibrated by themselves , plug them both in and calibrate using the receivers level. Get 75db at your listening area and your done.

This is the easiest way to get there. if you want to go deeper , understand this first then talk to me,

The Onkyo I also bought (the new 608 model) is 7.2, so I don't need a y-splitter. I figured it would be simple to calibrate them with that amp, I just wasn't sure if there were any gotchas or tips I should be aware of.

oh, i wanna hear how you like the 2 subs.

i have one PSWi225 and im gonna pick up a microPRO 2000, not too sure how they will work together. was also thinking about doing a pair of them and sell the PSWi225.

I did by mine ear...or should I say what sounded the most esthetically pleasing while watching a favorite movie. My trusty old AR is corner loaded to the far left of the viewing screen while the smaller Velodyne is directly below the viewing screen just a little to the right of it. The Velo is a front firing speaker so, I wanted it aimed at the listening area. The AR is down firing and with it corner loaded as it is disperses nicely when there is an explosion or what not. Not the most scientific way of doing it but, it works.

I have both subs (Velodyne DPS-12 and Infinity PS210) on either side of my couch, and it kicks. I calibrated both subs to 75db - 80db is a little too hot for my room.
Pick up an inexpensive SPL meter, tripod or boom mic stand with a camera adapter. Link here and follow the directions.

F. Attempt to match the output level of both subwoofers.

1. Use the receiver / processor internal LFE test tone while adjusting the volume control on the subwoofer to perform the following:

2. Turn one subwoofer on, and adjust the output level to 80 dB using an SPL meter.
a. Ensure the SPL meter is located where the first Audyssey measurement position will be taken (see section V.), and is set to “C” and “Slow”.
b. If you do not have an SPL meter, adjust the level by ear.

3. Turn off the first subwoofer, turn on the second subwoofer, and repeat the procedure.

4. Turn on both subwoofers and calibrate with Audyssey.
