Holy old thread resurrection.  Sad to see names from this post from members who have passed away.

True, I didn't even look at the post date.  It came up in a search. My bad.

I wouldn't worry too much about the low impedance dip in the

RF-7's...it only becomes a problem when you start pushing your

amplifier to its extremes - which means you need a better amp anyway.

When you're pushing the amp hard, you'll notice some loss in the low

end because the amp isn't capable of supplying the current for long

enough - with the RF-7's it just happens earlier (a little over 3dB

earlier to be exact).

But yes, having two woofers in parallel causes every impendance to drop

in half...so if the speaker was a one driver design, you would have a

minimum impedance of 5.6 ohms, which isn't uncommon for an 8ohm driver.

The impedance of a driver is actually a function of a few variables so

it is going to depend on the T/S parameters of the driver needed to

achieve the design goals. I'm not sure if it's an actual trend, but it

seems the wider the frequency range drivers have lower dips in the

impedance (like the RF-7 woofers that go from 30Hz to 2kHz).

Btw, does anyone know precisely where the dip occurs? I would assume somewhere in the

Hello All,

I`m new to this forum but have been lurking for a couple of days. You people seem to give solid advice to newbies such as myself. My system is:

Philips 55pp9401 HD ready tv

Sony V555es receiver

Pioneer dv-444 dvd player

Xbox gaming console

Klipsch sf-2 mains

Klipsch sc-1 center

Klipsch ss .5 surrounds

KLH 15 asw-200 sub

To me mt system looks and sounds pretty doggone good. A friend of mine came over to watch a movie the other day and he said my system sounded okay,but the klipsch reference speakers would blow mine away. My question is how true is this statement? Do my synergies sound that bad compared to the reference series? Any input would be greatly appreciated,Thanks.

 

The Synergy series uses aluminum dome tweeters where as the Reference series uses titanium diaphragm compression drivers. Titanium being considered better by some. - Synergy uses injection modeled graphite (IMG) polymer woofers where as the RF line uses Klipsch's patented Cerametallic technology.Oct
