See All Kustom PA Powered PA Speakers

A rock-the-house pair of speakers for bands on a budget.

This Kustom KPC15P pair are 100-watt, powered speakers with 15" Kustom-built loudspeakers and piezo HF drivers. The PA speaker is tuned to deliver rich, balanced tonality while accurately reproducing a wide variety of audio content.
Each Kustom KPC15P powered speaker provides balanced XLR and TRS 1/4" (balanced/unbalanced) input jacks. These may be used to connect a wide variety of line level devices such as non-powered mixers, preamps, keyboards, drum machines and other audio devices including music players such as iPods and CD players. The Kustom KPC15P speaker's volume control adjusts the overall level.

Their TRS 1/4" line out jacks may be used to daisy chain 2 or more Kustom KPC speakers for a wider dispersion of sound. For example, if a non-powered audio mixer has been connected to the Kustom KPC speaker's input, the line out of this first speaker may be connected to a second speaker's Input. This is a daisy chain and it often requires shorter cable hook-up lengths versus connecting the second speaker directly to the audio mixer.

Since its inception in 1966, Kustom has produced high-quality, affordable PA products, and the Kustom KPC15P PA speaker continues that tradition.

  • Each speaker
  • One 100-watt, Class AB, built-in power amplifier with current-limited protection circuitry
  • One 15", Kustom PA Speaker
  • One piezo horn with wide dispersion flare
  • One balanced XLR Input jack
  • One TRS 1/4" Input jack
  • Volume control
  • One TRS 1/4" Line Out jack

Good sound at a fair price. Order this powerful and versatile speaker pair today!

Comments about Kustom PA KPC15P Powered Speaker Pair:

I ordered this pair for my home studio but found them to be very large and heavy. I returned them and exchanged them for a single speaker. I really liked them, but the fact that they're 50 pounds each made it hard to lift onto a stand.


Would go to a higher spl but at this price I will keep them

      Comments about Kustom PA KPC15P Powered Speaker Pair:

      I haven't had the time to do a good evaluation. I tried them in my studio and they sound real clear at low sound levels, but gets a little bassy at louder levels. Not to sure about the spl, cause my 100 watt Sunn amp is louder , side by side at 2, and it is also 100 watts.

      Stellar when paired with Kustom PA112S

        Comments about Kustom PA KPC15P Powered Speaker Pair:

        I use these in conjunction with a pair of Kustom PA112S Subwoofers as a full-range studio monitor system, where "full-range" refers to 20-Hz to 20,000-Hz, which is the full range of normal human hearing.

        [NOTE: The "full-range" aspect is very important for mixing and mastering, because most musicians, singers, and producers are "fundamental tone hearers" (as contrasted to "overtone hearers"), and fundamental tone hearers are not so easily tricked by the "Missing Fundamental" auditory illusion, hence fundamental tone hearers need to hear the deep bass to mix and master correctly, and if the deep bass is not there, then fundamental tone hearers are spinning wheels and wasting their valuable time. Do a web search on "fundamental tone hearer" and "Missing Fundamental", where there are links to an easy test provided by the University of Heidelberg to determine whether you are a fundamental tone hearer.]

        The key is to augment the KPC15P Powered Speakers with a pair of Kustom PA112S Subwoofers, which also are powered, and this is easy to do, since the Kustom PA112S Subwoofers have a full-range "pass-through" jack (1/4" TRS), where there are two ways to connect the units, with one being to run an XLR microphone cable from the preamplifier or external digital audio interface to the KPC15P Powered Speakers, and then to connect the "pass-through" of the KPC15P Powered Speakers to the Kustom PA112S Subwoofers via 1/4" TRS guitar cords, while the other way is to connect first to the Kustom PA112S Subwoofers using 1/4" TRS guitar cords and then to use the 1/4" TRS "pass-through" to connect to the KCP15P Powered Speakers, where both units have 1/4" TRS input and output jacks (the output jacks are "pass-through"), but the KCP15P also has an XLR microphone style input.

        In a small room ([20' wide by 20' long by 12' high] or smaller), these units are vastly overpowered, so you need to be very careful with the volume levels, where 1 to 3 is plenty and really should be measured in real-time with a NADY DSM-1 Digital SPL Meter, which is not difficult to do.

        When using the combined units (15" powered 2-way units and 12" powered subwoofers), the easy way to set the levels is to begin with a well-balanced professionally recorded, mixed, and mastered hit song that you like as the sound source--where the single version of "Billie Jean" (Michael Jackson) is excellent for this purpose--and to set the Kustom PA112S Subwoofer volume levels all the way off, where you work on the KCP15P Powered Speakers and set their levels with the focus being hearing crisp and clear mids and highs, while being aware of the stereo image and stereo center, of course.

        Then you switch to the Kustom PA112S Subwoofer units and gradually increase their volume levels until you hear the deep thumping bass and kick drum. Once this is done if you need more mids and highs, then you can increase the volume level of the KCP15P Powered Speakers and then adjust the Kustom PA112S Subwoofers, all of which is easy to do, but it is best to have a NADY DSM-1 Digital SPL Meter to verify that the maximum loudness is approximatley 85 dB SPL, where the range of 80 dB SPL to 90 dB SPL using "dBC" weighting is preferred, since it does not filter-out the deep bass when measuring. If you set the volume levels initially using "dBA" weighting--which is fine--and then switch to "dBC" weighting and the "dBC" weighted levels are higher, then this indicates that the deep bass is a bit hot, but having a bit of extra deep bass is nice, really, so it depends on what you like.

        Every once in a while, engineers design something which has what one might call "magical" aspects, like the Gibson Les Paul and Fender Stratocaster electric guitars in the early-1950s, a handful of microphones, a vacuum-tube Marshall stack with Celestion 12" 25-watt Greenbacks, vacuum-tube VOX AC30 with Celestion "Blue Bulldog" AlNiCo speakers, and so forth, and this particular combination of powered loudspeakers (KCP15P Powered Speakers and Kustom PA112S Subwoofers) certainly qualifies as having "magical" aspects or a Gestalt "sweet spot", if you prefer.

        I augment the Kustom loudspeakers with a Behringer UltraCurve Pro Model DEQ2496, which has a real-time analyzer (RTA) feature when used with the associated Behringer calibrated microphone, and while the specified frequency range for the Kustom PA112S Subwoofer is 30-Hz to 150-Hz, the subwoofers actually go deeper, which gets the overall system down to 10-Hz to 20-Hz in the small listening room scenario, which is not a problem, because the volume levels are low, which maps to more headroom and so forth, hence the very deep bass frequencies do not damage the woofers.

        These also make an excellent full-range loudspeaker solution for a home theater or karaoke system, where for home theater use, you will discover that movies actually have a lot of deep bass in the soundtracks, effects, and so forth, and the fact of the matter is that this combination of powered loudspeakers when properly adjusted sounds just as good as a top of the line studio monitor system that costs perhaps six or seven times as much, which is an abstruse way of stating that with the aforementioned Behringer calibration unit I am very comfortable going head-on with the approximately $6,500 top of the line JBL studio monitor system at 85 dB SPL, which is the ideal listening level for mixing and mastering.

        And you can use this combination of Kustom powered loudspeakers as part of a custom electric bass or electric guitar rig, where you connect the electric bass or electric guitar to a Behringer Bass V-AMP PRO Rack Modeling Preamp and run the Bass V-AMP Pro stereo output to the Kustom powered loudspeakers, and if you need massive punch or whatever, then use the dual 15" Kustom KPC215HP Powered Speakers or add a second pair of the KCP15P Powered Speakers, where the key to stuff like this is the fact that what typically are categorized as "PA/DJ" loudspeaker units nearly always cost less but sound better, because folks who do sound reinforcement could care less whether a particular musician endorses something, which maps to sound reinforcement folks focusing on specifications and quality rather than being dazzled by sparkly stuff, where it also is useful to note that these Kustom powered loudspeaker units have Class AB power amplifiers, which is excellent.

        Also note that the Kustom powered loudspeaker units require line level inputs, which maps to the line-out of a CD/DVD player, television set, external digital audio interface like the MOTU 828mk3 Hybrid, or one of the Behringer units, including the stereo line-outs of the Behringer V-Amp PRO, which works nicely for rhythm and lead guitar as well as for electric bass guitar.

        And remember to be very careful with the volume levels in smaller rooms, because these are surprisingly powerful PA/DJ sound reinforcement loudspeaker units.

        Comments about Kustom PA KPC15P Powered Speaker Pair:

        I just bought these for fun and am thrilled. Yes, an equalizer would be a great addition. Apparently these are only offered in pairs, now...I bought 2 individually and am not inclined to repeat all the stuff from the original reviews (which are excellent, btw). I live in a 3000 sq ft warehouse and these babies fill it with sound and scare the neighbors...super loud, gut wrenching, ear bleeding monsters...amazingly good sound for the price, imho.
        Basic, exactly as advertised.
        Everything on the surface is plastic, so not ready for a rough and tumble road tour, but excellent for lighter usage. They look and sound great and it seems they should hold up indefinitely with minimal care. It's "good" plastic, ha!
