Dynavox is the best kept secret in high end loudspeaker drivers. They were engineered in France and their motor structures were optimized using Finite Element Analysis techniques. This tweeter features a 1-1/8" treated silk dome, ferrofluid cooling for higher power handling, and a heavy cast aluminum faceplate. It also utilizes a specially damped rear chamber for a lower resonanant frequency and crossover point. It offers exceptional clarity and smoothness, even at high output levels!

Rated 5 out of 5 by from High quality sound at a low priceUsed this tweeter to restore an old pair of JSE - Infinite Slope, Model 1's. These tweeters sound very clean and crisp, and have improved after breaking them in for a few months. I would use this product again in a heartbeat!

Rated 5 out of 5 by from Really Sweet !!!!!Bought 2 of these along with Parts Express Crossovers & Tang Band Subwoofers. Built my boxes modeled after the SR71 ported specs.They are clear clean and crisp as could be. For my First time build these are super nice !Everyone including my wife and kids agrees these are giant killers. They prefer the sound of my small speakers over my kappa 8's.I bought these from the reviews here and would defiant recommend them.Thanks PE.

Rated 5 out of 5 by from SPL curve for Dynavox tweeterThe manufacturer spec sheet is a bit outdated (2006), so I am including the raw SPL curve taken by TrueRTA software in 1/24octave resolution, and then input into the FRD response blender excel file to extract minimum phase.If there was a way to add the MINphase FRD file, I'd do it to help the DIY community looking to build a speaker using this speaker...>> This is an EXCELLENT tweeter for the money. Well built, and once broken in, a very detailed and clear sounding tweeter, with a fantastic alloy faceplate (which doesn't bend during installation).(the manufacturer spec sheet doesn't do this tweeter justice)I hope this review helps you in your decision to buy this tweeter.

Rated 4 out of 5 by from Quality upgrade.I upgraded my 3-way center channel with this tweeter and I'm very happy with the improvement. The clarity is great with enhanced vocals with movies and sports programs. This has a well built product with solid metal faceplate and heavy rigid terminals. I auditioned it in a 2-way first and it was clear throughout it's range crossed at 2800.

Dynavox TD2801XL 1-1/8" Silk Dome Tweeter

Hi, would these be good upgrade tweeters for a pair of Cerwin-Vega VS-80's? Looking for smoother, fuller highs. says these speakers have a crossover of 3600Hz.

We do not have a cross reference available for this type of thing. Please contact our tech support for more help with this question, or 800-338-0531 x1.

Asked by: BIG JACK
You can either use a variable L-pad like below, or a fixed resistive L-pad by using a 1.5 ohm resistor in series and 12.5 ohm in parallel after the crossover.

What is the thickness of the front mounting plate of these drivers? Also, has the manufacturer or anyone else produced a set of frequency response, distortion and impedance graphs?

Asked by: BJKinAU
The flange thickness on this tweeter is 4.5mm or .177".

height of dome for recessing?

I have a pair of 3.5 way? dual woofer Dante cabinets 3/4 mdf from the 80's and the factory speakers where rear mounted and cabinets covered on three sides with fabric.Does anyone know how "deep I would have to recess this tweeter so that it doesn't rub the fabric when I redo them? I intend on recessing and front mounting all the drivers.Maybe someone knows an accurate way to recess a speaker when there is already an existing hole?Didn't know where to ask that last question Thank you much.
Asked by: Doofus
The dome of a tweeter does not need to be flush with the baffle, this can actually cause ripple affects in the response. Instead you want the flange of the tweeter as flush as possible to prevent this from happening.

will this tweeter mate with aurum cantus ac-180f1 mid/woofer for a2way

Asked by: zachman
Both are quality drivers and should mesh well together. You can cross over anywhere in the 2k - 4k range depending on whether you like woofer or tweeter covering those ranges. I often cross my designs over at 3k even if the tweeter is capable of lower. The tweeter is slightly more efficient than that woofer so L-Pad to taste. Sounds like a killer combo.

What software will open the freq data into a graph?

Asked by: edgey
You can use either Microsoft Excel or the free "libreOffice" "calc" spreadsheet programs.In libreoffice, use insert, sheet-from-file, play with the settings until it makes some kind of sense, then load it. Then you will have to delete cells (or highlighted groups of cells) being sure to "shift left" until all of the data lines up. Then you click the "chart" button and go through those settings until it makes sense, making the frequency the domain and the remaining two columns the range... I did this with the impedance, phase charts and it came out good. I'm a bit concerned by the phase response at really high frequencies, but oh well...I agree that it would be much more convenient if the values were provided as a CSV or XML file.
