HiVi TN25 Fabric Dome Tweeter is rated 4.7368 out of 5 by 19.
Rated 5 out of 5 by from High ValueBought five of these for temporary replacement of Morel mdt 44 when a voice coil burns out. These HI VI's don't sound as good as the Morel's but at about 1/10 the cost of the Morel's they deliver a good 50% of the performance.

Rated 5 out of 5 by from Mellow, clean sound with a small mounting diameterPE was having a special on these at the same time that I got an itch to build a pair of bookshelf speakers, so I picked up a pair along with two Dayton RS125-8 5-inch Reference woofers.A custom Linkwitz-Riley crossover at 5kHz is significantly above the minimum that these can tolerate, but even so, the high-end output from these units is extremely clean and mellow. I can listen to them all evening without getting fatigued, and the off-axis response is adequate for my use as nearfield monitors on an office cubicle desk.The 89dB rated response is a fairly good match for many smaller woofers, although I did L-pad them for a better match to my 85dB-rated woofer. Also, the relatively small diameter of the rear chamber means the baffle can be cut with a hole saw, rather than requiring special work with the jigsaw or plunge router.I would definitely consider these again for another bookshelf speaker project.

Rated 5 out of 5 by from Amazing Tweeter For The Price!!Pros. - Clean, Natural sounding easy to listen to. Also handles high volumes well. Fantastic tweeter I have 3 sets of them in different builds and love them all.Cons. - Small faceplate makes mounting a bit more difficult.

Rated 5 out of 5 by from SmoothFor the price this is an excellent tweeter. A clean sweet sound equal to drivers 2 or 3 the cost.

Rated 5 out of 5 by from Fit My Needs & sounded good!I bought two of these based on favorable reviews and electrical/acoustic parameters. I have a mediocre pair of old aftermarket Sony 4 ohm 6x9" speakers on the rear deck my car. My plan was to disconnect the crummy mylar tweeters and mount the new HiVis next to the existing speakers on the deck. I used 14.7uF of capacitance each and protected them from direct sunlight with speaker cloth stretched over a flange I manufactured for them that recesses the tweeter slightly so the fabric does not come into contact with the dome. After connection, voila! Worked perfectly, voicing transitioned well with the adequate bass of the Sonys and efficiency matched nicely as well. The Sonys didn't have a true crossover as apparently the manufacturer just used the natural roll-off of the woofers, so my solution, (around 2,200Hz 1st-order x-over), worked just fine! Previous comments concerning transparency and detail were accurate. I am pleased.

Rated 5 out of 5 by from Excellent performer, but what happened to the value?I just revived a pair of diy t-lines with Zeta .5 series crossovers, the TN25 crossing over at 4000hz to a vintage Rogers polypropylene mid-woofer and a no longer available Vifa M22WR-09-06 woofer doing the bass chores. An l-pad with a 1 ohm series and 10 ohm leg was necessary. Transparency and naturalness are its virtues. It amazingly handles the frightening penny whistles of The Banquet from the Jarvi recording of Ivan the Terrible and Christina Deutekom as the Queen of the Night with aplomb. It just never draws attention to itself. However, they've unfortunately doubled in price since I bought them. Nevertheless, an excellent performer, especially where space is a concern.

HiVi TN25 Fabric Dome Tweeter

Looking to build a pair of 3-ways using this tweeter, the hivi 4" mid (297-434), and 8" woofer (297-446).  Just wondering if they will play well together and if there's an ideal crossover PE sells that will work with this.

Crossover question.

If I'm using the HiVi TN25 and a HiVi M4N 4" Aluminum/Magnesium Midbass in a small boombox, about the size of a lunch box, is a crossover recommended? Thx.
Asked by: Reelz
very much so! A crossover is required to keep the bass frequencies from destroying the tweeter. With a 4 in driver you can get away with a higher crossover point, I would guess that a crossover point of around 3000-3500 hz with 2nd order filters would do nicely. But it would be best to model the drivers and create a custom crossover with Jeff B's spreadsheets or a similar modeler. Good luck!
