The STS-01's are a 2-1/2 way design, with a 1" coated silk dome tweeter, and four 6" poly woofers.
The tweeter on one speaker is mounted on the left side, while the other speaker in the pair has it mounted on the right. Depending on your setup, you will likely prefer them arranged either with the tweeter on the outside or on the inside, so be sure to try them both ways.
On the rear, there is a single set of speaker binding posts.
The PB10-NSD subwoofer uses a 10" long-throw driver and 350 watt power amplifier in a rather large enclosure. When I tested it, I had not looked at the price yet, and the results led me to figure this thing would clock in around $1,099. But, no, true to the SVS philosophy of giving your something that will shatter windows for a few bucks, the sub is priced at $499.
The 10" driver is a long-throw design, and I can attest to that fact, because when I ran a 25 Hz sine wave through it, my pants legs were flapping in the wind coming from the port when I stood 4 feet away.
The 325 watt BASH amplifier has a simple set of controls, including gain, crossover frequency, and phase. It also has speaker-level as well as line-level in and out for pass through to small satellite speakers. I used the line-level (low-level) inputs for listening and bench testing.
The new AS-EQ1 is an outboard EQ box specifically for subwoofers. The processing is via Audyssey technology, and thousands of points from 10 Hz to 1 kHz are analyzed and compensated for. It requires a software program to be installed on your computer (I suggest doing this with your laptop) to set up the EQ.
The rear panel has line-level RCA inputs for two subwoofers if you have stereo sub pre-outs (most receivers only have one sub-out, so I set it up to use both subs with a single sub-out signal). There are two sub-outs and a pre-out for one of your satellite channels for matching the output of the subwoofers to your receiver's other channels. I bypassed this step because I used the system in a two-channel setup, and it still worked fine. I just had to turn the volume control on each sub to match my other two speakers after I ran the EQ software program.
