Cambridge SoundWorks - is highly regarded for designing some of the best sounding high-end home speakers, home theater systems, WiFi music systems and now the OontZ family of Ultra-Portable Wireless Bluetooth Speakers. We sell all our speakers directly to you our customer, eliminating the huge mark-up that retailers add to the price of a product.  We can then deliver high quality better sounding OontZ speakers with exceptional design at less than half the price of our top competitors.

The OontZ XL - Our team of industrial designers and acoustical engineers worked in tandem to deliver a light weight high fidelity portable speaker, with excellent bass output; loud enough for parties and to fill even a large room with high quality sound.  They designed an enclosure that is ultra-rigid, to minimize unwanted resonances, which can otherwise cause distortion.  They utilized a soft curve design for the front of the OontZ XL and a hemispherical design for the rear to alleviate the potential for diffraction problems that are caused by sharp corners and to help minimize vibration and distortion.   They incorporated a hemispherical design for the rear, substantially reducing the potential for distortion and vibration.

Our acoustical engineers then expertly matched the custom enclosure with two custom designed precision drivers that provide sharp highs and clear midrange. They implemented a tri-passive radiator design to deliver deep bass output.  The design layout of the three passive radiators has one facing forward and two facing backward serving to further reduce the potential for sound distortion and vibration.  The result is the OontZ XL which produces surprisingly loud volume, in high quality without distortion even at maximum volume.


'Champagne at a Beer's Price'

Review by Amazon Customer M. Garic "TruthTracker":

'Excellent speaker for a portable USB speaker. Between my husband and myself we have all three of Soundwork's Speakers and we are extremely happy with each of them. This one is obviously the best as per the price but it's still amazing value for the quality of sound that you get. If you are looking for audiophile quality sound then don't buy a portable,USB speaker, however if you are after an excellent quality USB speaker then you can't go past this one! The bass is deep and rich without being overpowering for the sake of it. It is well balanced with the rich and clear mid range and the nice clear tops. The overall sound is warm yet each level is distinctively clear and rich and the volume is great! Even at high volume it doesn't distort. The build quality is excellent too. It looks great and so is it's distinctive shape. It's nice to touch too with the soft touch coating that's used on it. Some have said it smudges easily, however unless you have very damp or greasy hands I've not had any problems with it. The only time was when I had just put moisturiser on my hands and it easily wiped off with a couple of wipes. There are other speakers out there that could compare to this however you will pay at least double for the privilege! Thank you to Soundwork's for making a such wonderful quality speaker at such a low price!' - review on Amazon.com
