Product Details

Peerless 830985 2-1/2" Full Range Woofer

Tymphany/Peerless full range drivers set the standard for quality audio in products including flat panel televisions and sound bars, MP3 and cell phone docking stations, and multimedia PCs. With their high power handling, smooth, even dispersion, and low distortion, the Peerless 2-1/2" full range drivers can be paired with the Tymphany LAT250 for great bass performance. A neodymium motor structure and double-venting system keeps dynamic range intact, as the transducer can handle more power and dissipate excess heat efficiently. An anodized aluminum dome provides superior sound dispersion and off-axis response. An inverted semi-progressive surround reduces distortion, especially at high output through long excursion. The driver's direct connected dome dust cap (attached to the magnet system voice coil) improves dispersion at high frequencies, providing superior sound at the higher frequencies. The inserted copper cap on the pole piece ensures control of the system impedance, thereby extending the upper frequency range.

Peerless 830985 2-1/2" Full Range Woofer
Peerless 830985 2-1/2" Full Range Woofer is rated 4.75 out of 5 by 4.
Rated 5 out of 5 by from Tiny Speaker Exceeds ExpectationsThis little driver really surprised me. It's range was much better than expected-the low end was much more prominent than expected for its small size and yet it still managed the high notes with great detail. It does get a little bright in the upper mids into the highs at times, but overall does exceptionally well for a single cone full range driver. Puts out a lot more sound than I expected also, very loud for what it is. Stays clear unless you really push it.Very well built, interesting venting on the voice coil. Has held up perfectly in a small powered project I purchased it for. Matches perfectly with the (also tiny) 15W x 2 Dayton Amp board.They may seem a little pricy, but I am glad I bought them.

Rated 5 out of 5 by from Great Bose Sounddock replacement!I got a portable Bose sounddock for cheap at a yard sale with a buzzing right woofer, I temporarily fixed the right woofer but I decided to replace both of them at the same time. These drivers fit perfectly apart from the mouning holes, you have to drill out or cut out the mounting tabs in the corners to make them fit (word of warning, the plastic is quite brittle to process with caution). I compared the sound to the original paper drivers and these peerless drivers sound a lot cleaner and the bass is a lot punchier.They are a bit bright at times but that to me just makes the dock come alive! They have little to no distortion at high volumes. I would definitely recommend these as replacements to anyone witha bad dock!

Rated 5 out of 5 by from Does what an aluminum driver shouldIt's very bright, just like you'd expect. Don't buy an aluminum driver if you can't handle the brightness, you'll be sorely disappointed. That being said, with the proper EQ this speaker sounds so pure and clear it's amazing. I have 31 bands of electronic EQ per speaker so I wasn't worried about the ring outs that characterize stiff cones in the 1k to 4k range. All in all, with EQ -> get a rigid cone like this, without EQ -> too bright, go with paper or other (not aluminum).

Rated 4 out of 5 by from Not too bad of a driver.Low end is clean and high end also but the mid range is a little clouded with volume. Has a tendency to peak in the 1k-4k range. If you have an EQ to fix this then it's all good. Going to try another set in 8ohm and see if that's the difference to tone them down a bit.

Recommended enclosure? Will it, two of those, work inside 7x4x2 inch case. As a sidenote, what parameters suggest compatibility with such a dimension.

Asked by: arjunm009
The recommended enclosures for this driver are listed on the product page. Two of these would work well in that enclosure assuming you keep it sealed, but they will only play down to about 150 Hz.
