inexpensive tweeter to match vifa TC18WG-15-08

[SQ Kid]

i noticed parts express was doing a one day sale on these guys, and figured they would be nice for a new set of speakers. however, i dont know what tweeter to match up with these. i was thinking maybe something from Dayton, but if anyone knows of a better budget tweeter (preferably around $30 or less per pair) that would go decently with these, lemme know

also, if anyone has built something with these, what size enclosure worked best for you? just trying to see if anyone else has given these a shot.

Specifications:
*Power handling: 35 watts RMS/100 watts max
*VCdia: 1"
*L1: .8 mH
*Znom: 8 ohms
*Re: 5.45 ohms
*Frequency range: 40-4,000 Hz
*Fs: 41 Hz
*SPL: 86dB 2.83V/1m
*Vas: 1.03 cu. ft.
*Qms: 2.96
*Qes: .63
*Qts: .52
*Xmax: 4 mm


thanks

Bump. I was thinking about AP210Z0 (24L, 89dB, F3 ~57Hz, F6 ~42Hz), but now am considering 2x TC18WG (40L, 89dB, F3 ~58Hz, F6 ~46Hz) for 60% of the cost. Any comments on the Audax versus the Vifa?

If you search there is a thread on large vented boxes (140L) with dual TC18WG drivers. F3 ~35Hz. There are tweeter recommendations.

Have a look at the Vifa TC20TD05-06 and should match the TC woofers. Quite a nice good valued tweeter.

I just ordered a pair of these today. Dunno what I'll do with them but they were on sale and I couldnt resist. Prob gonna go with a sealed encl.

thats exactly what i did. i hate big sale pics, they always make me buy things

I was so close to getting a pair of these and the Audax TM025F1 while I was at work yesterday but I wanted to go home and see if I needed anything else before I made my order. By the time I got on to order the sale was over. Would have made a good budget speaker. Now I cannot seem to find anything I like under $50 or so.

thanks for the recommendations. i probably will stick with vifa for the tweeters, especially seeing as they are in the price range. has anyone built these things into cabinets yet? i've really been looking to do a floor standing setup, whether its sealed, ported, or better. any sizes that lend themselves better than others?

Hello all, this is my first post to this forum!

This might be a bit off-topic, but I couldn't resist posting

I have a 2-way speaker project 'in progress' which uses Vifa's TC woofers and tweeters. The woofer used in this project is 5,5" TC14WG49-08, 7" TC18WG49's little brother. And the tweeter is earlier-mentioned TC20TD05-06.

They are to be installed into 14L bass-reflex enclosure, tuned around 44Hz.

Nice thing is, that If I build this 14L bass-reflex box and then for some reason want the 'closed-box' -sound, I can plug a piece of foam into the port and enjoy 'Qtc=0,6 sound'. But because the F3 for closed approach is quite high, I don't think I will ever need that
For a novice like me, it's quite interesting to notice how porting boosts bass performance...even for this small(ish) cabinet.

For Qtc=0,6 closed box: F3=~87Hz, F6=~63Hz
For bass-reflex: F3=~44Hz, F6=~38Hz

Later I might add some little active subwoofer to this system. The closed enclosure might be good for this use (no need for highpassing?).

so anyone else touch these things yet? i know i cant be the only guy to grab em at that price....

I bit on the DOTD sale too. I bought 4 of 'em looking for an MTM design. I did a bit of modeling and found that a ported design would need ~4cu ft box to get some low f3s out of these 7" ers. Not the route I was looking to take, so I am going to mess around with an open baffle design using these woofers with active digital equalization (via the behringer ultra curve). I think in an open baffle design these drivers would be able to tolerate some eq'ing to get decent bass output at modest SPL levels in the neighboorhood of say 90 and pusing it, 100dB. My past few speakers have been sealed so I wanted to try something different. The sealed models I did just didn't give the f3 I wanted out of 7" ers so I figured I could active EQ them in a sealed enclosure but that just wouln't be any fun, so open baffle it is!

Oh, I'm also thinking of using the tangband 1-1/8" tweeter because I have it laying around from an old project. The tweeter has sounded nice so far and it has a small faceplate, ideal for mtm stuff, so I'll see how it goes. I already modeled up a crossover w/FRDs passive crossover designer and managed to get a decent looking third order electrical on both the tweeter and woofers at around 2000Hz, with a 4rth order acoustic. The freq response gradually slopes downward from about 100Hz to 5kHz, which will help out with the bafflestep/open baffle bass issues.

I'll keep you posted on the project if you want, and you guys keep me posted on what you are doing with these buyouts as well.
