I opened 1 cab, hooked up and it did not work at all, very tinny, no bass or mid. I opened the second and it worked great! I filled out the forms and had to resend the cab back, still waiting for a new one. They are sending, but the Xmas surprise is not going to happen. I love the spark product lines, between my friends we have 6 Spark40, mini, but the cabs should be tested before shipping. I'm just glad I didn't wait until Xmas to find out as the 30 day return policy would have expired.

I have guitars, but recently got a bass. Looked at bass amps and then found that Pos G came out with this new CAB for less money. 140 watts! and it matches my My Spark Mini's styling, which I love. The bluetooth makes the Spark a winner since the backing track music goes thru the same speaker! Before the new CAB, the bass guitar was too much for the Spark Mini alone. With the new CAB, it can rock the walls and just about blows the windows out! Super impressed! Great low-end! I played it at 1/2 volume and my ears are ringing. Afraid to turn it up all the way now. Shipping was 1/2 the time they quoted. Excellent packaging. Thank you Positive Grid!

This Cab is awesome! I have the Spark 40 amp and the Cab works perfectly with it and sounds great and LOUD! It doesn't take much to EQ patches/presets for the bigger speaker. Streaming YT backing tracks sounds glorious too! I also play bass through it and that sounds amazing as well. And, I have a ME-90 processor and it sounds fantastic with the Can too! This thing is so versatile and powerful! Love it!

It's a little early, but so far, so good! Bass response has improved greatly. My acoustic-electric sounds so much better, almost like a direct input to a large sound system. I plan on using it at an upcoming Karaoke Christmas party as a powered vocal PA speaker. Should be interesting to see how it sounds.
Fun to have this. Sounds really good for the price point and seems well built. I’ve tried it with the Spark 40 and a couple of similarly budget minded amp modeling units (TC and Vox) as well as a little Boss bass amp. They all sound as they should, but it’s best with the Spark 40, mainly due to the additional amp that sounded good on its own already. Nice bit of kit.
...way too much bass and compression and when idle it sounds like a mic'd ventilation fan. BUT IT IS LOUD. Go for it kiddies. It also amplifies the quirky-ness of the spark switching. Not a serious product at this time unfortunatly. Wish it was. Returned mine and ate the shipping. Good customer service though.
If mine actually sounded like it should… it has a massive Roar when just turned on and nothing plugged in.. even with my spark amp plugged into it still has the Roar….. I’m extremely disappointed that whomever Dans and other idiots I’ve been emailing say there’s Nothing Defective bout a roaring sound coming out of the speaker cab….. is Positive Grid gonna make this right since you all are a multi million dollar company… no one has offered an exchange nor reimbursement for the $287.83 I spent back in October for pre order……. There’s more videos popping up on your FB they have the same exact issues as mine…. Your gonna get a lot of negative feedback very soon if Positive Grid does not stand up do the right thing for the customer…..
I was early buyer of Spark 40, waited months for it and it changed the way I play guitar! So worth the wait. I then ordered the Cab the day I heard about it, wait time was shorter and I really really like my Cab. I only have 1 issue. It is bass heavy. I love to use the tone cloud but in order to get the best sound ( what Im hearing in the headphones) I will have to change eq settings, then re save it to the cloud so I can then down load the patch to my Spark 40 presets. Thats a real pain. That is the only thing keeping my review from being a 5! I would love some advice from your people on this if Im doing something wrong! Oh and BTW I have none of this hissing or white noise others are talking about, it works perfectly! Thank you.
I first bought my Spark 40, loved it! The tones and ease of use was perfect for me. Then I thought dam, more power! I hooked it to my PA, used special devices to “balance, boost, blah blah” but it would clip so bad no matter where I moved dials! I then got the email for the new cab! I thought finally, more power and the abilities to properly hook to a PA! I got so excited and couldn’t wait for the “expected delivery in 4-6wks” dam why tell me then! Anyway did the wait, finally got it and hooked it up!It is so boomy and muffled sounding, I was definitely disappointed! I am not a techy guy when it comes to electronics but I stumbled enough to get an acoustic tone good! Anything with the electric, sounds like a wet bed comforter is laying over anything that omits ... MoreI first bought my Spark 40, loved it! The tones and ease of use was perfect for me.

I own two for stereo sound and am supremely disappointed to hear that everyone is experiencing a surprise noise floor issue and everyone is flooding customer support for answers. Do they sound good - yesDo they get loud - yesAre they actually FRFR - sort of, I need to tweak every single rig I have to get it sounding goodDid they conceal a noise floor - yesThey're stating that "It's also essential to note that most powered cabinets and high-power active PA speakers, such as the Spark Cab, may exhibit some degree of noise floor, which should be considered normal. Please rest assured that this does not indicate any quality issues with the product."The noise floor isn't mentioned in any of their promos.
