This is a great Center Channel and remember when watching movies or music most of dialogue and the vocals as well as music plays through the center channel so it is not an area to skimp on quality! The center channel (2200 C) has two features that help optimize it according to the room acoustics. First, it has a "High Frequency Energy" control which changes the "tilt or roll-off slope" of the tweeter.This control has 3 settings:1. "Reverberant" (decreases the high frequency output of the speaker) for rooms with an abundance of reflective surfaces like hardwood floors and glass walls.2. "Damped Room" (increases slightly the tweeter's output) which can compensate for overly absorbent rooms with lots of soft surfaces.3. "Average" which worked well for my room which has a combination of large glass windows as well as large couches and carpeting.Second, it has "Boundary Compensation" or "Normal" toggle switch which is able to "adjust the lower frequency output of the speaker to compensate for the typical sound colorations caused by placing the speaker too close to a TV screen or building it into a wall cabinet". I found the best position for my setting (center channel on a bracket slightly above a 62” DLP) was "Normal".It has been fully checked out and is guaranteed to arrive in undamaged condition and good working order. Don’t take a chance buying something that is sold “AS-IS” and has not been thoroughly checked out, when you can have something that is guaranteed to arrive in proper working condition for a few dollars more! You will not be disappointed. Don’t be outbid at the last minute by $1.00 or miss the auction closing time because you forgot! Use the “Buy It Now “ option and own it today for a fair price! Local Pickup is always welcome. Buyer pays shipping. Also I travel a lot in my job and I do not always have e-mail available, so from time to time I may take a few days to respond to your questions or to ship your item. eBay requires a handling time so I checked 4 days to cover me if I am away - but I usually ship in 1-2 days. Just ask if you need it quick. I tend to over-pack so I will guarantee that my packing will meet the requirements of the carrier so that insurance will cover the damage should there be a claim. Local pick up is always fine! With over 17 years of selling audio gear on eBay, and 100% positive feedback and over 2,500 transactions, you can rest assured that your item will arrive properly packed and exactly as described.Specs:2200 C Center:● Type: Sealed Enclosure. 2-way D’Appolito Array● Tweeter: (1) 1” Soft Dome Woofer: Two 4-1/2" GLH● Magnetic Shielding: Yes● Frequency Response: 90 Hz - 20 kHz ± 3 dB● Recommended Amplifier Power: 10 - 140 Watts RMS● Sensitivity: 90 dB● Crossover Point: 3.5 kHz, 3rd Order● Impedance: 8 Ohms Compatible● Dimensions: 7.5" H x 14.6" W x 7" D
