Hello, I am getting one Mach 5 IXL 18.2.2 driver, maybe two, but would like to use REW to see the response graph after moving the box(s).

I have a Dell Inspiron B130 Laptop that REW is installed on, and everything is stock (except for the battery but that doesn't matter lol).

I would like to keep the price of the mic below $20 if possible, but could do around $40 if the more expensive mic is needed.

Would I just need a mic? What kind of mic should I get? The results don't have to be VERY accurate, just enough to see the differences in moving the driver(s) around.
It would be In-Room testing also, if that would matter any,

Thanks for any help

The cheapest new meter (with a cal file from our download site) is the RadioShack meter.

To measure above ~3KHz and generally more accurate you would require the Galaxy CM-140.

The best mic and preamp would be the ECM8000 and XENYX802.

You also require an external USB soundcard for most laptops, as they don't have a line-in facility. Mic-in is not suitable.

Would I need the preamp for just using REW?
Yes, the level from a mic needs to be raised to line-level to be usable, and also requires a phantom voltage to operate the internal electronics. Note if you use a mic, then you also require an inexpensive SPL meter for the REW setup.

An SPL meter has the advantage of being a (mic with preamp and meter) all-in-one package. That's why many people choose that route.

Some of the more expensive soundcards have internal mic preamps.

Hi Dylan,

If this is going to be in your bedroom you will not have many options for sub placement so REW measuring isn't a big deal. Personally, I wouldn't bother with the added expense until you can afford it.

If you follow Mike P's suggestions, plus read the other IXL builds you won't be disapointed and you WILL have a grin from ear to ear.
