<font color='#000000'>Hi, I am going to purchase a Denon 1804 90 W 6.1 HT receiver and currently have Klipsch SB-2 bookshelf speakers rated at 85 W.
I want to start building a speaker system with a center channel, reasoning that movies would benefit most from this unit. *Klipsch suggests matching the SB-2 with an SC-1, which retails for ~$280. However, I actually like the added features of the RC-25, which sells for ~$199. *See below for a head to head comparison of specs. Timbre matching is a factor; from a web site, it is suggested that it takes about a 4 dB change in mid or high harmonics to be perceived as a change in timbre, whereas about 10 dB of change in one of the lower harmonics is required. *
Questions: Can the SB-2 handle the wattage of the Denon in stereo mode? *(I've heard the power drops in 6.1 mode).
Can it be determined from the specs if the timbre of the two choices are close enough to be indistiguishable? *If not, what info is needed?
What's up with the difference in measuring sensitivity?
Did Klipsch overprice the SC-1? *It sure looks like the RC-25 is the better value.
Any purchase recommendations if you were in my shoes?
Parameter * * * * * SC-1 * * * * * * * * * * * RC-25
Freq. Response * *60Hz-20KHz * * * * * * *69Hz-20KHz *
Sensitivity * * * * * 95dB @ 1watt/1 m * *95dB @ 2.83 volts/1 m
Power * * * * * * * * 100 W * * * * * * * * * * 125 W
Enclosure * * * * * * Sealed * * * * * * * * * *Bass reflex, front ports*
Impedance * * * * * 8 ohms * * * * * * * * * *8 ohms
Drive components *Two way * * * * * * * * Tapered array**
Tweeter * * * * * * * *K-101-S 1" Aluminum K-130-DN 1" Titanium*
Tractix horn * * * * *5" square 90x60 * * * *5" square 90x60
Woofers (2) * * * * *K-1079-SV 5.25" IMG *K-1127-OV 5.25" * * * * * * * * * * * *
* * * * * * * * * * cone/cast polymer frame Cerametallic® cone/cast * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * *polymer frame*
HF Crossover * * * 2200 Hz * * * * * * * * * *2250 Hz
MF Crossover * * * ---- * * * * * * * * * * * * *250 Hz
* Advantage IMHO
** From the Klipsch web site: a 2.5-way design, eliminates the acoustical interference between drivers that plagues most horizontal center-channel speakers. This technology allows both woofers to create intense bass, while only one works with the tweeter to acoustically blend the midrange. The result is a smooth, clear sound not just directly in front of the speaker, but off to the sides as well, where conventional center speakers often exaggerate or eliminate sounds.</font>
