🔊 Bass-Boosted Bluetooth 5.0 Stereo Audio Amplifier for Home Speakers: BT30A Review

This TINY little amp sounds GREAT. I was amazed when I turned it on for the first time. I hooked it up to a stereo radio, two speakers over the shower, and a "homemade" 6 1/2 subwoofer on the side. Alexa Echo connects via Bluetooth. I didn't really think the subwoofer would have a lot of power, but I was pleasantly surprised. It was perfect for our fairly large master bathroom. Highly recommended. That's a big advantage of singing in the rain.

The first few months I was so excited about this. I was able to play my vintage floorstanding speakers from bluetooth enabled devices and it was great. However, after a few months it started losing the bluetooth connection. Rarely at first, then more often. It also happens more frequently the longer the device is on, so after about 30 minutes it's difficult to stay connected for more than about 20 seconds. I don't have this problem with other Bluetooth receivers/speakers etc., so the problem is

The only negative thing is that the crossovers for the subwoofer output are too small. Frequencies above 100 Hz are transmitted clearly through the subwoofer (if no speakers are connected, you can hear vocal notes). In combination with the Polk T-15 it still sounds good though. To be honest I use a DVC car subwoofer connected to 2 ohms. This can make the problem worse. Slightly reducing the "bass" helps to attenuate those frequencies above the subwoofer. And the T-15s are LOUD, so you'll never…

This amazing blue tooth power amplifier with subwoofer output has greatly improved my stereo system at a great price. I have outdoor speakers in my back yard where we have a lot of parties and they are hooked up to an old Sony receiver with radio, no Bluetooth and input only for Sony products and my old iPod. I was very limited until I found this amp. I chose this model with subwoofer outputs because I had a subwoofer that I wasn't using. Setting up the amp was easy, I removed my old receiver…

Look, I'm an audiophile. It takes a lot to impress me. I use this little amp for my computer with a BIC DV32B kit and a Pioneer TS-SWX2002 8" passive subwoofer. A very humble attitude, of course. But my goodness, this little amp sounds so nice. for passages. Sounds spacious and warm, like breathing only at high levels. Doesn't add much color. Focus the tone controls and it's really quite neutral. It's almost a shame that the tone controls weren't used. It doesn't matter how picky you are. If…

It's been a few months. I've used it with bookshelf speakers, Micca, NHT Super One and some Infinity. The subwoofers used were a passive Sony, an active 8" Infinity and an active 10" NHT. Bookshelves: Infinity were a bit extravagant. The NHT pumped out plenty of bass, almost too much with a subwoofer, and the Micca struck me as the perfect bookshelf partner when a subwoofer is used. For subwoofers, the amplifier works great with a passive subwoofer. Control the bass slider. The two active…

I use it to drive two vintage Advent midrange drivers and a 10" subwoofer. The subwoofer initially had power, but the amplifier failed. So I bought this 4.2 amp subwoofer to use a 100 watt subwoofer in it instead of the one in my unpowered subwoofer. This was easily done by removing the back of the subwoofer, cutting off the power cord and cutting a hole through the cabinet so I could connect speaker wire directly from the subwoofer of a 4.2 amp amp to the speaker. As long as I keep the bass…

RECOMMEND? Absolutely yes. TESTING: Only tested 2 hours so far, but so far so good. I checked the audio from the phone's headphone jack to the RCA amp - it works. Paired with the same phone via Bluetooth - works. (At first there were problems with the Bluetooth range, but it turned out that the problem was in the phone and not the amplifier). Paired with another phone and had great BT connection from around the house. SETUP: Running with two Bose 201 (LR) 8 ohm full size speakers and one Bose 4

Just got my BT20C Fosi Audio Amp and couldn't be happier! I had no problem getting it to work, even with a 30ft distance between it and a BlueTooth source. There's no noticeable audio lag, so lip-syncing with the video image isn't an issue. The device is VERY solidly built and nice and small. It sits on a table next to my sofa and is barely visible. My app is a little different from most as I use it as a headphone receiver for BT audio from my TV to avoid disturbing others in the house as we…
