Zerone 1 Pair 2" 4Ohm 30W Silk/Polymer Composite Dome Tweeters Treble Speaker HiFi Stereo Heavy Bass Car Loudspeakers

El producto funciona muy bien para su costo tiene muy buen desempeño lo recomiendo

I used these for home bookshelf speaker project, as well as a two way component setup in one car . Now i also have them in i a three way setup in another car . I have always loved the sound characteristics of the peerless dual ring radiators in all of my audio projects since the early 2000 s, and gave these a shot back in February. Since then i have purchased several pairs and havent got a bad one yet. with the right speakers to accompany these and the right tuning and placement , they help make such a good soundstage that you almost forget that your setting in a car.

One of the few open back tweeters that work well in an open baffle application. Eliminates the need for a second rear firing tweeter. Very reasonably priced.

To Whom it may Concern: I bought this tweeter to help out a friend and replace a few speakers in a monitor for him. Here are the Small parameters as I measured them if anyone could use them.Exported from the Dayton Audio Test System: DATS** Piston Diameter = 32.41 mm* f(s)= 856.3 Hz* R(e)= 5.395 Ohms* Z(max)= 10.99 Ohms* Q(ms)= 1.722* Q(es)= 1.66* Q(ts)= 0.8453* V(as)= 0.009794 liters (0.00035 cubic feet)* L(e)= 0 mH* n(0)= 0.3532 %* SPL= 87.58 1W/1m* M(ms)= 0.3372 grams* C(ms)= 0.102 mm/N* BL= 2.428* K(r)= 1.696* X(r)= 0.1177* K(i)= 7e-06* X(i)= 1.135

They are almost Identical to the Peerless by Tymphany XT25SC90-04 . The only deference I can see is the phase plug is copper . I own both . I am very impressed with the smooth airy response they provide . I have been working on eliminating the soft dome tweeters in every thing I own . I used to think they were great until I got to listen to a pair of Ring Radiators . You will not be disappointed with these . Especially for the price .
