Speaker/subwoofer for REW

Hi. Glad you're moving forward. I've never heard of anyone measuring a room with bluetooth speakers. The problem is probably not the Bluetooth wireless signal but the frequency response and polar pattern of the speakers.

These sport speakers aren't designed with critical listening in mind. If you bounce sound around the room, it'll be highly comb filtered once it arrives at your ears along with several other reflections. This is pretty much the opposite of what acoustic treatment is about. Even if you have a small 'stereo' sport speaker, the tweeters probably aren't facing your ears and, even if they were, they're too close together to make a meaningful stereo image.

So, to answer your question, you can probably get *a* result with those boomboxes but you'll likely get better result with a similarly-priced pair of studio monitors.

Hope that helps.

On second thought, I'll answer your email here because the information might help others. I assume / hope you don't mind!

As explained in my Web Store page, flat-rate consulting is based on $200 per hour, but those are "loose" hours. For most people who don't have endless newbie questions, the initial $200 is sufficient and includes a "reasonable number" of emails back and forth, or phone calls, or Skype if overseas. So the fee is not a "per room" charge, and the hour or two I'll spend for that flat rate doesn't have to be all at once either. Often people have initial questions, then a week or two later they have a few more questions which I gladly answer without charging again. So I don't do this like a lawyer and run the clock for every second I'm helping someone!

If someone wants to learn REW, we might both have REW on the screen as we talk on the phone and I walk them through the steps to measure and interpret. And then they know what to do without me when they measure again. But the help isn't unlimited. Someone with a large project that needs more help might be asked to pay $200 again. But that's only if I've already spent two hours or more and there are still other issues to go over.

I've never seen a laptop that has a suitable input for an XLR microphone. If you already have a mic then get something like the Focusrite Scarlett Solo USB sound card for $100. If you don't have a suitable microphone, then this USB mic is perfect because it requires only the one USB connection:

I assume any sound card in any modern computer will be good enough for REW. High quality converter chips are common and inexpensive. But any Scarlett would be just as good if not better. I'm certain that your 2i4 can record and play at the same time!
