Dynavox TD2801XL 1-1/8" Silk Dome Tweeter

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!

Dynavox TD2801XL 1-1/8" Silk Dome Tweeter is rated 4.6129 out of 5 by 31.
Rated 5 out of 5 by from Awesome Tweeter!I have used these tweeters in rebuilds of classic 8" two ways, car audio and even in higher end applications replacing Dynaudio D28s. The sound is sweet, never harsh. A great value. Oh, and they look good too.

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.

Rated 5 out of 5 by from Big ImprovementWow, These tweets realy brightened up my sound. They were the last component I added to a re-built pair of ADS 1290's and it put the icing on the cake.

Rated 5 out of 5 by from Dynavox TD2801XL- excellent tweeter. I built an MTM setup and center center around these tweeters and Focal drivers.- the DATs woofer tester showed impedance curves much different than the stock data on the right side of this page. I had an FS of 685, 850 and 975 from three tweeters, so I had to cross over above 2500, using a 2nd order LR.- I highly suggest using a series RLC notch filter with this tweeter, as it will sound much better, and because of the squirrely quality control on the impedance curves and FS.- this may be a Janzten Audio or Dynaudio knock-off, but it doesn't have the quality control of the original Dynaudio tweeters. I guess for under $40 each on sale, you can't complain too much.- overall, my system was +/- 1.5 DB from 37hz to 20k hertz with the system I designed using these tweeters.

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.http://www.parts-express.com/parts-express-speaker-l-pad-attenuator-50w-mono-1-shaft-8-ohm--260-255

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: BJK2
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.
