Gorilla in a shoe box!

Function and form, this is the end all set to be beaten! The KPM4 was a test to see how KUSTOM monitors and PA's performed; It was sitting in a room full of 15" subs and overpriced gear. (I've never thought of KUSTOM as a viable, reliable company, and the KPM4 changed my mind!) (Check out the PW50 as well, it's just as good, but a little more in the package. This is more of an extension, but I use it as I wish..) I demoed this unit, listening to some classic rock on it and was amazed at the output. Zero line noise when it should have been there from an unbalanced source. It event had zero distortion in the output beyond halfway to ? max volume. The response was stout and yet, it's so small and PORTABLE... I'm now building my acoustic & mobile recording rig from all KUSTOM active cabinets. While I praise the KPM4, I just found out about the PW50, with dual 4.5" and a high 3.5 piezo driver. It has 3 inputs, crossover, and lower response by a marginal amount. I am getting two of those as well. (Before you toss your head up, Kurt Cobain even played off of his Crest PA amp to keep it simple!) On a side note, I will be using the KPM4 (plus two PW50 daisy chained for gigging & recording rough in) as a acoustic practice amp and doing so with an acoustic preamp. For giggles, I'll also attempt to run my Fender directly without an amp. I will be using a SANSAMP PARA DRIVER to balance the line and throw some dirt onto the channel. Then I'll will use the SANSAMP Classic and pass it through my PARA DRIVER to replicate cabinets. Then I'll review again as an update! (I was in need of a studio monitor set, but I'm not the kind of guy to break for that kind of cash. They cost way too much and at the end of the day, you're stuck with a paper coned woofer that began dieing the day you purchased it. Don't even think about gigging with your 600 dollar studio monitors... they were never made for that kind of abuse. Not to mention the laughter...) Sorry for a long review, but discovering something 3 times as useful to myself is something worth mentioning. Take care and good luck!

Not as good as I had hoped.... might be ok if modified

I have a couple of Kustom PA50 speakers, which sound surprisingly good and are a tremendous value, with a lot of features for the money. I've used them as monitors and they work well, but I bought this because it's smaller and can be mounted on a mic stand. This product is done in by the failure to include any kind of eq to tame the absurdly loud tweeter. The first time I used it I fought dog-whistle feedback all night, and finally just turned it off. Since most small mixers don't have any kind of eq on their auxiliary sends, you get what you get, and if that's not usable, them's the breaks. A treble roll-off or even a pad switch on the tweeter would have helped to get more gain before feedback. Also, a handle doesn't seem too much to ask. The description on the web site says it has one but nope.... Since you can get the PA50 for the same price, and get two mic preamps, with 2-band eq on each, a stereo input for a phone or ipod, with a comparable amount of power, and two speakers rather than one, you just have to wonder how they come up with their price points.

    I just got this amp so I could hear my voice while rehearsing, and I really dig it! This amp can be pretty loud and really amplify your voice! Please buy it if you are looking for a affordable microphone amp.

    I recently purchased this Kustom monitor to use on stage for solo acoustic gigs. It's a solid little 50 watt monitor that works like it should. As a bonus, it also makes a good practice amp. My only criticism, so far, is it lacks a carrying handle of any type.

  • Works great as practice/travel speaker for my HX Stomp.

    I use this as a monitor for live shows, to give me coverage of most mids and highs of our tracks. As a bassist I need this to follow our tracks. and our vocal mix with the tracks. My bass runs through our system, but I really do not get my bass out of it, I listren for my basss out of teh PA speakers turned toward the audience and from my amp on stage. If you want bass response this speaker is not it. But to monitor vocals and other higher frequency instrument tracks, it works very well. My only complaint of the amp is that the volume control goes from zero at start to very loud with very little movement from the zero position. This may be due to a higher amplitude of input from my Harbinger V2315 link out function.

    It will function as a low impedance line out - it's designed for a microphone. I don't know what amp you're using.
