Paradigm vs. Definitive Technologies vs. Polk

[Seth=L]

Exactly. If you have the BP7006 or BP10B or Polk, you could set the crossover to 40Hz if your receiver allow it. With the Paradigm, it would be 60Hz.

Some people like to set everything to SMALL, though. But I like to set everything to LARGE and FULL RANGE.

So what kind of prices are you getting for these speakers and what is your budget?

I think you are missing a few things here.

One of the main reasons we use x-overs on receivers with all speakers set to small is to reduce the load and demands on the amplifier/receiver. At the same time it reduces bass humps and nulls, for a more even frequency responce and more dynamic capability.

Although I would love to have a set of speakers that were full range... I would never be happy with the bass coming from them, therefore I would need a big powerful sub... and to determine the x-over points... that is what analization is all about.. Let your room and room response tell you where to crossover.

Seth has it right... you have to take measurements to figure out where to setup your crossover for even FR. When I bought my Paradigms I crossed them at 60hz, cause "They go that low !!!" right... wrong... I had a major dip in my FR that was relieved when I crossed over at 80hz. Now she is smoother and I'm not missing that dump out of sound at the point.

If your speakers are not full range and you don't have the separate amp for power, then yes, I can see setting the speakers to SMALL.

But if you have a full range speaker + external amps, why not set the speakers to LARGE + Subwoofer?

1) Power is no longer an issue w/ External Amps.
2) You are covering the 20Hz-80Hz with Both the Full Range Speakers and Subwoofer, so you don't have to worry about missing anything like the humps and nulls.

I think the ideal Scenario is to cover all your "BASES", pun intended.

How about letting both the Subwoofer and the Main Speakers cover the 20Hz-80Hz spectrum?

I think both the main speakers and the subwoofer have their weaknesses. I think the main speakers cannot produce as much bass, and the subwoofer cannot produce as much clarity, details, and accuracy as the main speakers.

...The subwoofers in the BP7006 towers are NOT the Supercube III subwoofers...Second, pairing the BP7006s subwoofers with the SVS is no simple task...

You have two good points there.

1) The BP7006 have less interior volume and power than the SC-3. The BP7006 will produce more bass than any speaker without a powered subwoofer. But the BP7006 (or any speaker w/ built-in powerd subwoofer) cannot match a dedicated powerful subwoofer in terms of bass output. My thoughts were too simplified.

2) Yes, mixing 3 subwoofers is very difficult. Again, my thoughts were obviously very simplified and not articulated with details.
I think subwoofer bass management is a lot simpler for Movie soundtracks than for Music listening. For Music, I was thinking of using the Pure Direct Mode, which would totally cut off the LFE/Subwoofer. All you will be using are two full range speakers. Only use the dedicated subwoofer for movies. That's how I set up my HT room. At first I was trying to use 3 subwoofers for music and movies. But as you have stated, it is extremely difficult. So now I'm just using the dedicated Sub for movies.

I was reading an article in the latest Sound & Vision Magazine. They reviewed the (almost $4K) Outlaw Audio 5.1 Speaker System. Frequency response was like 90Hz-16kHz +/-4dB. At first I thought, "Man, those specs look like crap for a $4K speaker system!" But then I read the verdict: "Superb Multi-Channel Sound".

I thought, "Man, I guess you can just throw the specs right out the window!"

No I meant the PB10-ISD. I wanted it to be somewhat fair to the 7006's.

I keep my sub at 1/4

I just didn't see the PB10-ISD on the SVS website. Are they discontinued?

So you just keep your sub at 25% volume? And it still makes earthquake-like bass?

So tell me why do you like Polk Audio speakers so much?

I like speakers with built-in subwoofers and amplifiers. I especially like speakers that can be QUAD-amped.
Unfortunately, I'm not rich enough to own those $40,000 Linn Komri Quad-wire speakers.

But what is it about Polk Audio?

It's good to see your coming to your senses. LOL

The PB10-ISD was replaced by the PB10-NSD. The NSD is the new driver for that series.

If I turned my sub up it would cause severe damage through-out my house. My sub is not in a dedicated, well insulated HT room.

I'm only human. I'm getting there.

I think one of my many New Year Resolutions is to audition as many speakers as conveniently possible.

Like the RTi, and especially the LSi series from Polk.

I believe I already explained this, but I will try again.

When you have more than one subwoofer in a room, especially non-identical subwoofers, they have a tendacy to have bass humps (higher levels at certain frequencies) and nulls (dips at certain frequencies) because the bass from each unit can cancel out or augment bass from the other units. The bass well be uneven and unaccurate, so doing this is not suggested. The Definitive Tech tower series (assuming the OP wants Def Tech) is a much better solution if getting a seperate, superior subwoofer is what the OP is after.

My experiance with Def Tech supercubes and small passive driven subs from Def Tech have been the have sloppy uncontrolled bass and require ideal placement, and placing subwoofers in tower speakers is next to impossible. I have no doubt in my mind that the SVS will produce more accurate bass than the BP7006s.

So why have I so often seen the statement that "using two or more subs yields smoother, more even bass"?

I can't find that specification anywhere.

That is only with "Proper Placement" and is not easy to do.

Yeah, it seems like the actual magazine has more data than the website.
The magazine has the individual specs for each speaker: Front, Center, Surround, & Subwoofer.

Those are on "Very Rare" occasions. LOL Look at your last 10 posts.
