I bought the 308 to try at home with my guitar modeler at “bedroom volumes.” It has plenty of volume on tap for that at just 9:00 on the dial. If I were to need it for a small venue gig I believe it would work just fine for that application as well, because 12:00 on the dial was rattling items in my office. My modeler sounds nice and clear, just like with my nice over ear headphones.The 308 is also a nice lightweight and compact size. I could travel with modeler in backpack case, speaker in one hand and guitar in other and have one trip load in.

I love everything about these speakers. They are inexpensive, weigh nothing and are loud! I use them as floor monitors for a small 4 pc. band but you could use them as main speakers for a small room. I have been a JBL guy all my life but these work rather well. I wish they had a combo input but you could easily replace the XLR input if you wanted to. They also have a XLR thru output as well. Highly recommended if you don't want to break the bank or your back.

I am a working musician of 55+ years. I've been thru a lot of equipment. I bought two of these to use as floor monitors. Not really knowing what I would get for such a low price. Boy was I surprised. They are fantastic. They are more than loud enough. They are also very clear. Everyone in the band was really impressed. And added plus is that they are very lightweight. I am extremely happy with the purchase. I wouldn't hesitate to buy them again.

I've been using a QSC CP-8 for last 5 years with my duo. We use a single CP-8 high and behind for two mics, two guitars, and bass guitar. It works great and can cover large outdoors gigs. For the last 3 years I've been playing electric into a modeler while my partner plays acoustic guitar or bass. My acoustic guitar is currently retired.But with a modeler in my gig bag (usually a Spark Go these days, but I also have a UA Dream 65), I thought it would be nice to have something lighter for informal jams that could keep up with a drummer. At 25% the price and nearly half the weight of my CP-8 the TX308 seemed like a good solution. Its only shortcoming is I need a 1/4" female to XLR male adapter.Like the CP-8 you need to turn the bass down on your modeler if the speaker is placed on the floor. They are both voiced to be up on a pole. For music listening the CP-8 is no doubt capable of more volume. I did stress test the TX308 with bass guitar and it did not buzz or have any other issue. I'm impressed given the light weight and low cost. The overall build quality of the TX308 looks quite good to my retired electrical engineer's eye. If you want to run either speaker from a battery power station, they both draw about 5 watts running their DSP with no sound and are deafening loud at 10-15 watts of power from the wall socket.BTW, the Positive Grid Spark amps don't like having left and right (tip and ring) shorted together on their headphone output on the way to your powered speaker (sounds bad regardless of how you configure the output with the app: stereo or mono). A resistive summing cable is a bullet proof solution into a female 1/4" which might be TS, TRS stereo, or TRS balanced (3.5mm TRS stereo male with ~1K Ohm summing resistors to 1/4" TS mono).One other small, good thing to report is the handle molded into the TX308 case does not have any sharp edges. One of the nice things about the CP-8 is a great handle which I think matters compared to the sharp-edged molded handle in for example, the Yamaha DBR10. Another more expensive option, the Behringer B208D has no handle at all. If you're looking to travel light and make one trip from the car this stuff matters.

10": Sound quality is good. Nice flat response, not extra bright. I can add the shimmer at the console if I need it. The foot print is unbelievably small. I’m replacing the cabinets in the photo and the one to the left is an 8” Gemini RS-408 and the one on the right is a 10” Gemini RS-410. The 10” TX310 is nearly the size of the 8” Gemini! Just slightly taller. Aesthetically, it’s definitely an upgrade. Dispute the small size, the low end is pretty good. You’ll need a sub if you want to use these for a party, but they’ll work great as delays or generally to reinforce sound.I would NOT recommend these for beginners. There isn’t much in the way of protection (there’s an analogue limiter) and they will be very easy to blow. The mic pre level has a nasty ramp up right at the top of the knob and even if you slowly ramp up to it, it jumps suddenly and will probably catch you off guard. If you need to put a passive DI inline to take out a ground loop or something, be aware of this nasty hump and don’t let anyone else touch the volume knob. Also, there’s no EQ or mixing on the speaker itself. The Gemini has a mic in, line in with bal and unbal, an amplified mix out and a two band EQ, and it cost $150 at the time of purchase. Inflation is a MFer.These are perfect for adding sound distribution points in a larger system with plenty of control and processing from the console, or for rooms too big for a bookshelf system. If you’re a DJ looking to get these or the bigger cabinets, make sure you put a compressor with limiter inline so they don’t blow when someone decides to yell into a microphone.15": It gets just loud enough to the point where if you're standing in front of it, you'll consider turning it down. This is fine for me because I want the music to be enjoyable, not pain inducing. However, the big issue is that the bass rolls off at about 70Hz. This is fine for kick drums, and stuff like deep house will sound fine on it but if you're playing bass music (trap, other forms of EDM) you're going to be embarrassed. I was playing Beastie Boys' Brass Monkey at a party and there was LITERALLY nothing where the 808 bass drum was hitting. I believe it's hitting concert A1 which is 55Hz. Definitely take a sub if you're going to try to rock a party with these.I actually heard the Harbinger VARI V2315 15" last week and was pretty impressed by the bass. I need to go to guitar center to see exactly how low the bass goes, their website claims to have response down to 40Hz. For a frame of reference, the QSC K12.2 starts rolling off at 55Hz, and is down -10dB at 45Hz, so if you can still hear 40Hz on the Harbinger, it's giving the QSCs a run for it's money at almost a quarter of the price. I always thought their specs are BS because they're a no-name brand and the numbers seem too good to be true, but I'm going to bite the bullet and get a pair of the 12" version if I'm proven wrong. The Harbinger 12" is the same price as the 15" Alto.
