This Bluetooth amp converts any old speakers you’ve got into wireless wonders

By Caleb Denison January 18, 2015

I can’t even begin to count how many times someone has come up to me and asked me how they could go about converting their existing speakers into Bluetooth speakers. It’s clearly an idea folks are into, yet one with few simple solutions. In the past I’ve had to suggest Bluetooth receivers to pair up with existing stereo receivers or perhaps a small digital amp — hardly plug-and-play. But now, thanks to Griffin, I’ve got something I can recommend with confidence. At CES 2015, I found the Griffin 20, a compact and attractive Bluetooth amplifier that can turn nearly any pair of passive speakers wireless.

The Griffin 20’s 20 watts per channel won’t allow you to rock a block party, but it should be more than sufficient for casual indoor or outdoor listening. Let’s say you want to set up a garage audio system with some oldie-but-goodie speakers you’ve got sitting around — the Griffin 20 would be perfect. If you’ve got a subwoofer, the 20 can handle that as well, thanks to a dedicated subwoofer output.

This is no el-cheapo solution, either. I was impressed by the quality of the amp’s binding posts and gold-plated jacks. The large silver volume knob felt weighty, and I love the addition of a digital optical input for connection to another component like a gaming console or cable/satellite box.

At just $150, I think the Griffin 20 is a slam-dunk of a value. What a great gift idea! You can even bundle in a pair of excellent NHT Super Zero speakers for $300 total, or add in a great compact NHT sub at $600 for the total package at Griffin’s online store.

sony srs xb12 jbl flip 5 marshall stockwell ii bluetooth speaker deals best buy summer sale 2020 720x720

A portable Bluetooth speaker represents the cheapest way to upgrade the sound of your phone. They also allow you to take any party outdoors thanks to their ruggedness and extreme portability. Not all are created equal, though, but we're sure you'll be able to find a Bluetooth speaker with a set of features that will perfectly fit your needs and budget. Below are the Sony SRS-XB12, JBL Flip 5, and Marshall Stockwell II. All three are on sale at Best Buy starting from just $40. Read on to peruse which one suits you best.
Sony SRS-XB12 – $40, was $60

The Sony SRS-XB12 is proof that a tiny portable speaker can have it all: Great sound, fully waterproof housing, and best of all, affordability. At just $40 at Best Buy (down from the usual $60), this Bluetooth speaker may be cheap, but that doesn't mean it performs cheap. Weighing in at a mere 8.6 ounces and measuring roughly 3.7 x 3.0 inches, this speaker is small enough to fit inside a tote bag or even an oversized coat pocket. A metallic grille protects a single 46mm driver which is responsible for the killer audio. It can go surprisingly loud without any noticeable distortions, with a bass that packs plenty of punch. Of course, it doesn't compare to any large speaker with an actual subwoofer, but it's good nonetheless. Finally, the SRS-XB12's IP67 rating is pretty rare for a speaker at this price point. It's fully waterproof, provided the cover protecting the ports is closed. The Sony SRS-XB12 will make you forget that you're listening to a really small speaker. Get it for just $40 at Best Buy.
