500-watt, 15-inch Passive PA Speaker

This Passive PA speaker features a huge 15" main driver and a 1" exit driver. It handles a massive 500 watt (RMS)/1000 watts (peak) of power at 8 ohms impedance.

The speaker has a 50 Hz ~ 20 kHz (-10dB) frequency response and boasts 97dB sensitivity (1 watt @ 1 meter) with a peak sensitivity of 126dB. The crossover is at 3.3 KHz. The cabinet measures about 27.5" x 19.0" x 15.0", weighs about 37.3 lbs, and has an internal capacity of 5.3 cubic feet of air.

This speaker requires an amplified signal and pairs well with our 1000-watt, 12-channel Powered Audio Mixer (PID 604570). It connects to the amp using a 2-conductor NL4 cable.

Each order includes one (1) speaker.

Pros: Sound quality, volume.

Cons: Heavy on the front. Legs should be moved forward a bit.

I bought one of these speakers and I am not disappointed. I have used the speaker for local swing dances along with Monoprice's powered mixer, and I was surprised that the one speaker alone produced better sound quality than the many built in overhead speakers in the building. The room was quite large, which could easily hold a few or maybe even several hundred people, and the speaker was loud enough to be heard quite a distance away. They are very directional, just as most speakers are, and when moving out of the speaker's degree of sound output, it made them sound quieter and have less clarity, but that is the case with all speakers of this type. The degree or width of the sound is still very wide, but there is a definite sweet spot, which can be increased if two speakers were purchased. I am planning on purchasing a second in the future, but for now I only need one.

The one drawback with the design of the speakers is that the front is obviously the heaviest, and the front legs should be moved forward to compensate for that. You can see this in one of the pictures. If these speakers are placed on the ground or a table, they can be easily knocked over if bumped the wrong way. Ideally, speaker stands would be used to make the audio go over the crowd's heads, which would eliminate the possibility of them falling, but I just noticed this area of improvement.

Ultimately I am very satisfied with this product and will definitely be purchasing a 2nd in the future.

Just to give some details, my current setup is an iPad 2 with the 30 pin connector going to the stereo returns port on the powered mixer.

Pros: really good sound quality, lightweight, inexpensive, good build quality

Cons: none yet

Excellent value and really good sound and build quality. I bought these to replace 2 extremely heavy Yamaha 15" speaker cabinets, as I got tired of lugging those around from gig to gig. I use them for a couple of loud tribute rock bands in the LA area and they're perfect for our needs. We just run vocals and a kick drum through them and we have plenty of volume, warm vocal tones and plenty of headroom. I didn't do an A/B comparison between these and my Yamahas, but I from memory I don't feel I'm sacrificing any sound quality, and my guitarist believes these actually sound better than the Yamahas, which are almost 3 times the price. Highly recommended as they won't break the bank, or more importantly my back!

Pros: - Molded Plastic Construction
- Respectable Sound Quality
- Amazing Price Point
- Lightweight (comparatively)

Cons: - None so far

Preface: While I'm certainly an enthusiast, I would not necessarily describe myself as an Audiophile or a live sound setup expert. My current setup is under-powering the speaker with a TechnicalPro AX5000, which has an advertised power output of 5000W. In practice, however, it has an output of about 240W RMS.

Build Quality - In a word excellent. The cable connectors are very secure with no play (sometimes a concern in cheaper speakers). Most speakers in this price range are built from MDF or other similar fibreboard, which is heavy and prone to damage during the course of usage. Happily, this speaker is built from tough, molded plastic and the overall build quality is exceptional.

Sound Quality - Absolutely great for the price range. Obviously a speaker 3-4x the price will have better overall sound fidelity, but this speaker is certainly no slouch. I will have to update my opinion once I have an amp that can properly drive it, but for the moment it's fine.

Value - Very great value. I purchased a single speaker to try it out, but I will definitely be purchasing another. They will see use as personal speakers for light entertainment at parties and events.

These are a very respectable entry-level product for performers looking for live sound speakers that won't break the bank.
