Not true Mojo, my Realistic Mach's with 15" woofer had plenty of bass.

I just remembered that I did a 600 vs. Sony face-off last year. I don't believe I ever posted this but here it is. It was at that time that I discovered the 600 had a lower than normal input impedance.

Note the hump from 50Hz to 80Hz in the Sony and my comments regarding the lack of thump when I reduce the Sony's cross-over to 50Hz. The prices shown are what I paid. The bottom chart represents the maximum SPL I was able to achieve in my room. My room is 4,000 cubic feet and it is open to the rest of the house via an open stairway. The Sony believe it or not went louder but as you can see, I nearly killed it .

It looks like the little Sony tried valiantly to produce some low frequencies, albeit at the detriment to itself. Still, for 165 bucks you can't really fault it for anything.

Interesting results. I've never really experienced the so-called "punch" with my set-up. However, my brother-in-law has my old Klipsch speakers and sub and he's set them up rather well so they produce a sharp clean sock to the chest.

Sean,

What sub do you have?

From your chart, it looks like the "payoff" frequency is around 60Hz. I'll try adding a +6db, .15 b/w at 62Hz or so and see what it sounds like.

Mojo, great post. Thanks for putting that info up. It's hard to believe this, but I'm thinking I should try a pair of 350s...

The posted specs for the 350s say they play down to 18hz in room (though they don't say at what volume). This compares to 15hz for the 600... I honestly don't think there'd be much I would be missing in that 3hz range on the majority of material. Even now, on test tones at least, I don't hear much at all at 15hz in my room with the 600. (mainly the propeller sounds Mojo mentioned)

Max SPLs are pretty comparable as well, and since I don't need massive SPL in my size of room, maybe the 350s really would be more pleasing to me? The lack of any posted FR curve definitely makes it a bit harder to know what you're jumping into with the 350s, though the personal recommendations from Mojo definitely have me leaning that direction.

Sirquack, how do you think they compare on the low end? I know you have a huge room so it'll be a bit different, but since you have both in your house, you seem pretty tough to beat as a first-hand source of info.

I have a Hsu VTF3 mkII. Also, I run two Dominator D10 subs with it in my HT. With the three subs I get a relatively flat response in my room.

I bet I get a super-flat response when I finally tell that one girl how I feel, regardless of what room I'm in.

I'm guessing a slight hump is preferable?
