Product Details

1/2" Inverted Dome Tweeter Element 10 Pcs.

Speakers in a line array are always limited by their center-to-center mounting distance, driver-to-driver, when it comes to high frequency reproduction. When the wavelength being reproduced by the speakers is physically smaller than the center-to-center distance, the speakers begin to experience destructive interference (which is commonly referred to as comb filtering).

For instance, multiple drivers used in a line array that have a 2" minimum center-to-center distance will begin to experience comb filtering at and above roughly 6,750 Hz. This creates havok on subtle imaging cues, high frequency playback, and top-end sparkle. 

This 1/2" inverted dome tweeter element is sold in packs of 10 and are the perfect high frequency element for use in high fidelity line arrays. A 7/8" minimum center-to-center distance allows for unaltered frequency response all the up to and above 15,000 Hz! A low 450 Hz free-air resonance frequency allows you to crossover to a fairly large driver while maintaining seamless integration. The frame design requires mounting the tweeter from the rear of the baffle using a 3/4" opening and securing it in place with epoxy. 

Note: Higher power handling and output can be achieved by using multiple tweeters together, and using a 2nd-order 1,500 Hz filter. For example, a series-parallel group of four tweeters will handle 8 watts RMS/16 watts max while increasing the SPL to 72 dB. Two series-parallel group of four tweeters paralleled together (for a 4Ω load) will yield 16 watts RMS/32 watts max (without a filter) and increase output to 78 dB.

1/2" Inverted Dome Tweeter Element 10 Pcs.
1/2" Inverted Dome Tweeter Element 10 Pcs. is rated 3.0 out of 5 by 2.
Rated 4 out of 5 by from Best I've tried in this sizeI have tried a bunch of these little 1/2" tweets, and I find the top end the most relaxed and extended. If you think even 3/4" tweets have a beaming problem and still lead to listening fatigue, using these as super tweets might do the trick. I typically use these with a 2" or 3" full range woofer. Woofers at that size will obviously beam the treble. These tweets allow me to listen at arm's length without any listening fatigue. After a couple of hours, the top end is still relaxed and airy. More airy than any larger tweeter can do at arm's length, no matter the price. I can't vouch for any type of linearity of response, as my application merely does soda pop fizzle, but it really does put the air and soundstage back into the sound when used with the full range woofers (alone, the full range speakers lack air and sound dark).No beaming and ultra-detailed (and completely not harsh) talcum powder in the air is audio heaven for me. (Also, I did have to bi-amp the tweet with a little IC amp because the output level is quite low.)

Rated 2 out of 5 by from Not the same driver as CBT kitI was informed by PE tech support that this is not the same driver as in the CBT. I ordered 2 sets (20 drivers) and measured each one with EASERA. The response curves tended to fall into 3 groups, see plots. These might be used with a crossover above 2.5kHz, but not at 1kHz like the CBT. The problem with using these in arrays is that the phase is all over the place and would not add up coherently. This could be dealt with by sorting through however many drivers it takes to find enough that match. Used individually this driver's sensitivity is too low to be of much use. The SPL plots are in arbitrary dBs and measured at less than 1watt, on an "Infinite" baffle. As always, PE staff were most helpful in handling the return.

1/2" Inverted Dome Tweeter Element 10 Pcs.

Anyone who can give me the series/parallel combo to wire 8 (I can go up to 10 units if required) of these to arrive at a minimum of 2ohms load (running 15 watts RMS to this channel). Thanks

Does anybody have frequency response and impedance curves for these drivers? I plan on building a center channel with 25 of these tweeters and need a reasonable guess at the crossover frequency so I can select appropriate mid/ woofers.

Asked by: LoveToBuildSpeakers
You may want to ask this question on our Tech Talk forum, there are a lot of folks that provide third party measurements for many different drivers.

is this 1 tweet in 10 Pcs. or 10 tweets in 1 Pcs.?
Asked by: speaker freack
This is 10 individual 1/2" tweeters.

66dB/W/M sounds too low for a tweeter any chance thats really 86dB?

if it is 66dB this tweeter is essentially useless
Asked by: audvid921
This is in fact 66 dB, these are designed to be used for line array purposes where multiples would be used.

Does these tweeters require a seperately closed encloser? I kinda see that the backs are open

Asked by: mintos
This item mounts directly in the cabinet. First carefully measure and mark the approiate spot where you intend to mount this tweeter in your project, Take a second to insure that your spot on your cabinet looks right and has clearance front & rear. If installing accross duplicate cabinets insure sides are even if using center mounting and measure top and bottom to insure consistent appearance. If offest you will use "mirror matched" mounting for best look and sound. Create 3/4" openings working safely remembering neatness counts ! Insert driver from rear and epoxy in place after insuring your wires are soundly connected. Be sure to install a crossover capacitor or high-pass filter to protect your investment in time & money. Enjoy

36 of these approx. db output per L/R speaker?

I want to do a build similar to the CBT36 but smaller and cheaper and not as classy. Hooking 36 of these together for an 8 ohm load using the magic square trick just need the db from these so I can choose the right woofers and frequency cut I should use. thank you. Power consumption is not an issue.
Asked by: VusstoppyPro
With one (1) tweeter at 66dB 1w/1m, using 36 units of this tweeter would net a sensitivity of approximately 80-82dB.
