Review: NOT BlueTooth - Prime lists these speakers as BlueTooth-enabled; they are not. They're hardwire, and a pair require at least a 120 watt amp to push these 8-ohm jewels (eg, JBL VMA 1120) in sequence or parallel. That explained, they sound exquisite in a 30 x 40 outdoor space w enough loud (top - 90 dB), and pair with a TV w the right app.
Review: Impressive and any volume - I've had these installed for about two weeks now and so far I'm really impressed. As other reviewer have said these speakers pack a punch at high volume. Unlike a lot of outdoor speaker they remain crystal clear and have fantastic low end for such a small cabinet, but what has really impressed me is how good they sound as the volume is lowered. I've found with a lot of outdoor speakers I've tried that they start to sound muffled at lower background listening levels but not these they remain nice and clear even when barely audible. I've also been pleasantly surprised at how even they sound over a really wide radius. No matter what volume you intend to use these at if you want an outdoor speaker with great sound and a wide listening range you've found them!

## Questions & Answers

**Q: Can someone plz explain to me in layman terms what the difference between 28-1 and 28-1L is?**
A: The 28-1 has a rotary 70V transformer with several tap values and an 8 ohm bypass built in.
The 28-1L is 8 ohms only.

**Q: Is this a pair or just one?**
A: Amazon lists four (4!) different speakers under one listing. You will absolutely have to determine which speaker you intend to buy. On this listing done are sold in pairs and some are sold in singles. The way the product selection is configured doesn't make it abundantly clear which speaker has option on pairs vs singles. Go on interwebs and check retail price from authorized seller like Sweetwater to determine if the price on Amazon is for a single or pairs

**Q: Is this sold as a pair? Its not stated anywhere. Thanks**
A: Yes they sell them as pairs

**Q: I have four of these installed at my home.  Each one runs directly back to an amp.  What is the recommended amp size in watts (per channel)?**
A: 175 W Continuous Program Power

### ⭐⭐⭐⭐⭐ Great all around sounding speaker
*by J***I on January 30, 2021*

Set these up for a rooftop bar to replace existing speakers. They handle a little more power at 70v than the old ones but sound infinitely better. They have a smoother low end sound. I would recommend these speakers.
