After 4 mos of owning Primus speakers, I am happy with both the product and the service.
I bought an Onkyo 604, a pair of 360's, and a C25, followed by 4 160's to act as my surrounds and rear surrounds. All this was at the low-low closeout prices that we were seeing in January. I figured that that should keep me entertained while I contemplated subwoofer options.
About 2 weeks into the fun, I noticed a flatulent sound coming from my left surround speaker at certain frequencies, and after a brief session of troubleshooting, I determined that the woofer driver was to fault. I consulted the warranty information and looked on their website, and found that if you provide a copy of the bill of sale along with the serial number, and they will grant you a one-time free order of up to two replacement parts per speaker, in the event that a warranty service center would be inconvenient. I sent them my information and recieved an email saying that the assembly was on backorder. I figured I could wait a little. Fortunately I didnt have to since the box from Harmann arrived 5 days later. Four screws and two wire clips later, all was well, and the old driver is now a paper weight on my office desk. Bonus fact: quick examination reveals that the 160s and 360s are made of entirely interchangeable parts... the woofer assys, the tweeters, and the plastic surrounds are al the same in different configurations. Between my array of speakers, I should be well covered on replacement parts should something unfortunate occur.
Anyhow, I decided that the best bang for my buck on a subwoofer was to build one of Rythmik Audio's DS12 Servo kits, and I am shocked at its capabilities. I had never experienced subsonics like this in a home unit. Rather than outclassing the Infinity components, I think it just helps to lift them up, esp since I can cross the Primus speakers over at 80hz to unburden them a bit. Between the clarity and dynamics of the Primus array, and the speed, accuracy and depth of the Rythmik kit, I feel like Ive jumped the turnstile into home entertaiment heaven, paying a small fraction of what I should have to get this kind of quality.
Suffice it to say that the addition of an Oppo 981 for the sake of playing SACD, DVD-Audio and hearing the full range of DTS recordings has been a hoot.
Now, to start saving pennies for when the Samsung HL-T6176S comes out.
