    Driver recommendations - Hiquphon

    Hiquphon is a boutique manufacturer of OEM 3/4" dome tweeters and custom air core inductors. Like Skaaning, this is a labor of love for one dedicated and talented designer. Unlike Skaaning, Hiquphon's tweeters are priced within the reach of the average DIY'er. Despite being an OEM selling to such prestigious high-end vendors such as Fried and ProAc, Hiquphon does offer a limited number of "standard" tweeters. Each model comes in matched (+/- 0.5 dB) pairs with individual (and extremely accurate) curves and design data for each driver. Common characteristics include an outrageously high 0.9 mm Xmax (2.2 mm pk-pk physical excursion), 8 ohm impedance, and advertised distortion under 0.2%. Bucking current practice, but similar to the Scan-Speak Revelator, Hiquphon eschews the use of ferrofluid.

    1. The OWI (D2094-8708-03) is a lower sensitivity (87 dB/W/m) tweeter with, quite literally, ruler flat response on-axis from 2 kHz out past 20 kHz. Response at 20 kHz is only 5 dB down at 30 degrees off-axis. The design goal of the OWI is extreme smoothness and listenability. response waterfall

    2. The OWII (D2094-9008-03) has slightly higher sensitivity (90 dB/W/m) than the OWI with slightly less flat response. This is deliberate. A small "shelf" in the response from 2-5 kHz is designed to complement midrange or bid/bass drivers with a slightly rising high end response. Even with this FR contouring, for any other tweeter, this would considered excellent performance! Off-axis Performance is actually better than the OWI, being only 3 dB down at 20 kHz. The design goal of the OWII is analytically precise transient response. response waterfall

    3. The OWIII (D2094-8908-G3) "gold dome" tweeter is essentially the OWII with a gold dome. Modified versions of this unit can be ordered to match the Bud Fried designs, including the use of ferrofluid.

    Note:
    The Hiquphon OW I/II/III, along with the AccutonC223/6, Human 002, Scan-Speak R2904/7000, Morel MDM33, and the Alison Acoustics 4010203 (available only as a replacement part for Allison loudspeakers) are considered by many to be the ultimate electrodynamic tweeters.

    Driver guidelines - Tweeters:

    Prior to ca. 1960, the predominant tweeter designs were either cones or horns. Cones were generally found in lower priced consumer gear and horns were more often found in audiophile systems. Since that time, dome tweeters have pretty much supplanted both. Cone tweeters have always suffered from problems with beaming and resonances, while horns have always been expensive to manufacture and tricky to get right. Domes, on the other hand, can be as cheap and easy to work with as cones, while still challenging horns on sound quality (but not efficiency).

    Early domes tended to be made of hard plastics or soft treated fabric. Current technology uses a variety of materials as noted in Appendix B above.

    For DIY projects, most of my respondents recommend sticking to 1" (25 mm.) dome tweeters and avoiding the 3/4" units altogether. I've generally (more on this qualified statement in a moment) followed this advice because it's easy to see why. There are few things that a smaller dome tweeter can do that a 1" dome can't. Add to that the facts that a smaller dome will almost certainly have lower power handling and have to be crossed over at a higher frequency. Still, I have included a select few smaller domes for those who want the slight edge they offer in extended and off-axis response. It's still fairly safe to recommend against using one in anything less than a 3-way system (although even this has been done successfully in a handful of commercial systems).

    Having said this, I have to note that there exists a small minority of 3/4" dome tweeters that turn this advice on its ear! Most significantly, the line of 3/4" domes from Hiquphon are among the best dome tweeters in the world and certainly an outstanding value.

    A fairly recent addition to the technology of dome tweeters is the use of ferrofluid. Ferrofluid isn't a single material, but a class of some 50 magnetically and thermally conductive liquids of varying viscosities which are used to fill the gap around a tweeter's voice coil, thus providing heat dissipation (i.e. greater power handling), mechanical damping, and lowered mechanical resonance. Still, some manufacturers (Scan-Speak and Hiquphon) have moved away from using ferrofluid in their top-of-the-line tweeters, claiming improved transient response and transparency.
