SVS Speakers..

The SVS speaker systems have front speakers that are too small for decent system performance. This is a problem with most HTIB setups.

I recommend that you get the JAMO S426HCS3 5.0 system and add a subwoofer. The JAMO setup goes for about $300 and you can get the Polk PSW505 subwoofer for around $250. That will perform far better than 98% of the HTIB systems.

The PSW505 is a much better subwoofer than the ones that come with any of the HTIB setups.

Of the HTIB systems available, I would recommend the Martin-Logan MLT-2 system which you can get for $450 or so and has somewhat better front speakers and subwoofer.

I'm not sure which "crossover" you mean. Each speaker box that has two drivers or more will normally have an internal crossover to separate the lows from the highs electronically. That is sort of like asking if a car comes with tires.

If you already have a subwoofer, then the JAMO 5.0 system is the perfect thing for you, and is only $300-400.

Rythmic makes some of the very best subwoofers, but of course they are a bit expensive.

One that is quite good and has been available recently for only $300-400 is the Klipsch RW12D.

Sony makes speakers costing $59, and they make speakers costing $27,000 per pair (the Sony SS-AR1). It might help to know exactly which model you have if we are to attempt a comparison.

for under 500 shipped, the svs's are hard to beat. they are miles ahead of any sony htib systems. and the svs are not a htib setup like the other person was saying. get the scs02 for l/c/r and the sbs for surrounds and your good. My brother has the same exact setup with a hsu vtf3 with about the same room dimension as you so i can tell you first hand they are great for the price. big soundstage, very neutral sounding, and imaging is good. I dont recommend those jamo 426's. for some reason they do not sound good and are cheaply made. I would jump up to the jamo s606 for 399 at vann's. The only thing i dont like about the s606 is the center channel. it doesnt match up well with the towers since it uses smaller drivers so i just use my system as a 4.1. another good setup in your price would be 2 polk monitor 70's 2 monitor30 for surrounds and cs2 for center.

The Sony SS-MF600H is a 3-way speaker.

It has TWO crossover networks inside each of the speakers.

Since it is a 3-way system, it has a crossover to separate the bass frequencies from the circuits connected to the other drivers and another crossover to limit the frequencies that go to the tweeter.

I have no idea why you think they don't exist; they most certainly DO!!! The speaker cannot function properly without them (for one thing, the tweeter would burn out in no time at all without a crossover to limit the frequencies that go to it...).

To replace the crossover (filter, if you wish...same thing...) that came with the speakers and make it work properly, you would have to have extensive data on the electrical characteristics of each driver and an extensive background in electronic filter design. It does not sound like you have either one.

In a cheap speaker like that, the tweeter "crossover" is probably nothing but a resistor and capacitor to limit the tweeter current and filter out the lower frequencies. It is still a crossover, even if it is a relatively simple one.

I owned the SVS SCS-01 series for mains a one point and have since given them to my brother-in-law. IMHO, these are a steal for the money. They are a very neutral sounding speaker and play clean. They will be a noticeable upgrade to your Sony speakers, and I compared the SVS speakers directly to Polk rti series speakers that I owned and the SVS were superior in sound quality,

You will need a good subwoofer as the speakers are designed to roll-off at 80hz. These are an incredible deal for the money.

I have a full 7.1 SVS system since several years back ( first generation ), comprising:

* 03 X SCS - 01 for the front array;
* 04 X SBS - 01 for the S/SB duties;
* 01 X PB -10 ISG SW.

Bottom line: so far, so pretty darn good and I couldn't be happier with this little awesome setup, though
