Heavy Duty Titanium Super Tweeter TW44
Heavy Duty Titanium Super Tweeter TW44 is rated 4.5333 out of 5 by 30.
Rated 2 out of 5 by from Nice price, but doesn't meet sensitivity specI evaluated this tweeter as a candidate for use in an arena sound system forhigh-end reinforcement. It has reasonably smooth response which extendswell above 20KHz. However, I found that it falls far short of its 104dB SPLrating, and ranks 8-12dB lower in efficiency relative to some other models,such as the PRV Audio TW350Ti, which I also tested recently.This photo is a composite scope trace of the near-field response of the twosubject tweeters, sweeping from 2KHz to 22KHz. The higher-amplitude darktrace is for the TW350Ti and the central bright trace is for the TW44:

Rated 5 out of 5 by from Outstanding for the priceThis tweeter is ear-shattering, yet clear and crisp. The full-metal frame is rock-solid, unlike other tweeters with plastic frames. The included capacitor does its job without any issues. My only complaint is that this driver is difficult to mount. But once you do so, the high-end of the spectrum is loud enough for a party in an area the size of a school gymnasium.

Rated 5 out of 5 by from Awesome tweetersThese tweeters replaced a pair of El Cheepo tweeters that I purchased at Meijer as a quick fix. I had a hard time believing the 200 watt rating on them, however I have faith in the watt rating on these. These tweeters are very clear, reproducing everything from 3KHz (which is where I have them crossed) and up beautifully. Something to be weary of is that these do sound a bright from 7KHz to around 10KHz; even when 4ohm resistance was added to use in the 8 ohm crossover network (which effectively brought the SPL down to 98 DB) there is a peak around 8 KHz. I’ll probably buy a pair of L pads to bring down the peak. Anywho, I still highly recommend these; keep the power under the maximum and they should last you a while. Cheers!

Rated 5 out of 5 by from It's a great dealSpeaker performed as described. You can't beat the price either. No issues mounting it. Don't use the supplied template.

Rated 5 out of 5 by from Big sound... little moneyI put one of these in my center channel speaker coupled to 4 4.5" 100watts each mid woofers and it keeps up fine with very clear highs . I might even be caught saying it sounded as good as a silk dome. I was a little skeptical at first worrying they might sound brash but they were very smooth sounding jewels. I have one grip to Pyramid the cut you give for these tweeters is too large .

Rated 5 out of 5 by from Perfect match for my systemI purchased this driver to augment my Fostex Fe167e in a MLTL cabinet. After the fullrange driver modifications, I found them to be a little lifeless on the top end. After replacing the included cap on this tweeter with a smaller value Dayton PMPC cap , my highs came back to life better than expected. In fact, I leave my L-Pad set at max (probably due to this tweeter being placed below the FE167e driver and having a heavily damped room). I do suggest replacing the included cap.

Heavy Duty Titanium Super Tweeter TW44

hi i have a question, can i use this tweeter with a 15" Peavey Black Widow bass Speaker er

the bass cab that i have this speaker in does not have a a Horn or Tweeter in it, what other parts do i need to buy to install properly in the cab and make it work with the 15" Bass Speaker
Asked by: rubenbass2guitar
You can absolutely use these in your bass cabinet. You do not need a separate cab, nor a mid driver if you're just looking for some detail for slap. You should use a crossover @ 3 or 4K. The power handling on the tweeter is excellent, and although the frequency response chart is not accurate it is a great tweeter for your application. Undercut the cutout or you'll end up with a loose fit. (do a test cut in a piece of scrap) There are no concerns with it rattling or coming loose if attached with the supplied mounting screws. I would not use it in a studio or stage monitor situation.

I have a pair of Boston Acoustics VR20 towers, can i use this titanium tweeter to replace tweeter on tower?will it sound good?

Asked by: muska27
The Pyramid Heavy Duty Titanium Super Tweeter TW44 is a loud strong upper mid and high frequency tweeter with a crossover point using the supplied capacitor of 2000hz.Your Boston Acoustics VR20 towers (circa 1993 - 1998) are a great 2-way tower speaker designed well before digital sound was the norm. BA traditionally are somewhat mellow speakers. Designed and built in the East coast where architecture is aged wood and lots of upholstered room fixtures, the speakers built in the region are typically more mellow than west coast speakers where the architecture is steel, concrete and modern.The Pyramid Heavy Duty Titanium Super Tweeter TW44is something I would characterise more as a wet coast speaker. Being titanium it has a very strong and flat responce but it is very efficient. When combined with the woofers in your BA towers there is likely to be an imbalance between highs and lows that would require some serious eq to balance out.I am not putting down your BA's, but instead suggesting a conventional tweeter set up rather than a projecting bullet such as Part #: 270-252. This is a reproduction of a phenolic ring tweeter developed by CTS in Kentucky as an OEM for dozens of speaker manufacturers such as Marantz, Acoustic Research (AR), Sony, and many many more.From PE speaker description:This is a drop in replacement for the Marantz Imperial Series cabinet speakers models Marantz Imperial 4 5 6 6G 7 8 and 9 with common part numbers 137-7348N, 137-7350, 137-7816 and 841-1022 and HLM312A. Also used in Radio Shack Nova series cabinets Nova 7b as well as the Altec Lansing Santana 891 speakers, RSL Rogersound Labs, Acoustic Research AR 4x and Rectilinear XI Cabinets from the 70's.I would not be surprised to find it is a direct replacement for your BA Towers. It has a very smooth sound characteristic and should be less harsh and able to be balance with your systems bass - midrange - treble contour controls.Another product available at PE is the Tang Band 25-1742S 1" Fabric Dome. This speaker would be between the titanium tweeter and the phenolic ring tweeter I mentioned above. It would be a strong high end tweeter but is more suited for a 3-way enclosure. Because of the box volume of your towers, you could easily add a mid-range speeker, tweeter and a new crossover and convert them to a great sounding 3-way speaker enclosure. All of the items needed to do this are also available at Parts Express.Good Luck

This tweeter, as a few others I see are rated 4 - 8 ohm. Can you explain

Asked by: Davis Basses
Not that the following stats have much of anything to do with impedance once driven with normal program material, but you can look at other stats such as Revc or DCR to see what value they post. In this particular case, it is 3.5 ohms. Label it as a 4 ohms tweeter if you want and base your crossovers etc on that value.

Can I use these with the crossover in my Cerwin Vega DX-5's?

The crossover in them is set at 5000 hz. Do I have to do any additional work or can I just set them up as is?
Asked by: Bauchma
These can be wired as-is with that crossover.

how low can i cross these over at?

Asked by: benny215
These should be crossed over at 2000 Hz using a 12 db per octave slope, or 4000 Hz minimum with a 6 db per octave crossover.

Should i rate these as 4ohms or 8ohms?

Asked by: rodimuz
These have a DCR of 3.5 ohms so I would use the 4 ohm spec. The 4-8 ohm listing refers to amplifiers this will work with.
