Product Details

Radian 1228-8 Diaphragm Fits Most Altec 1" 8 Ohm

Radian manufactures replacement diaphragms that fit popular compression drivers found in home and professional loudspeaker systems. Each diaphragm employs aluminum alloy dome/Mylar® surround construction to provide high efficiency, accurate reproduction, and extended bandwidth. Radian's use of sophisticated materials and processes results in diaphragms that have equivalent or better performance than the original. Made in the USA. Fits 8 ohm Altec 602, 802, 806, 808, 902, MR902, 904, 908, 909.

Radian manufactures premium replacement diaphragms that fit popular compression drivers used in professional loudspeaker systems. Each aluminum alloy replacement diaphragm provides high efficiency and accurate reproduction with extended bandwidth. Replacement diaphragms are designed and manufactured to have equivalent or better performance than the original.

Compression domes are precision formed from heat-treated, structural aluminum alloy and bonded to a copper-clad aluminum voice coil with a Kapton® former utilizing proprietary tooling. Aluminum has a higher strength-to-weight ratio than titanium providing low-distortion, high-fidelity response that delivers clear, crisp music and speech for theatrical, auditorium, stadium and church installations.

The suspension is made of specially developed Mylar®. Utilizing a Mylar® surround enhances the replacement diaphragm’s reliability and eliminates fatigue stresses that destroy other compression driver diaphragms. The Mylar® surround also provides good dampening of the voice coil/diaphragm assembly for smooth, low-distortion, linear output with excellent transient response. To ensure longer diaphragm life, our high temperature voice coil former and advanced adhesives permit each replacement diaphragm to sustain high RMS and peak power levels, equivalent or better than the original.

The diaphragm/voice coil assembly may be rapidly readily replaced in the field. The self-aligning diaphragm assembly assures simple installation and accurate alignment with same polarity as the original.

Unparalleled power handling, high-frequency performance, reliability and low-distortion make Radian premium replacement diaphragms the preferred choice for loudspeaker repair centers, consultants, sound system designers, contractors and engineers worldwide.

Radian 1228-8 Diaphragm Fits Most Altec 1" 8 Ohm
Radian 1228-8 Diaphragm Fits Most Altec 1" 8 Ohm is rated 5.0 out of 5 by 6.
Rated 5 out of 5 by from Painless ReplacementI had ordered a diaphragm for the Altec 846B (VOTT) horn driver from another source - it was bad and did not even fit on the pins and screw holes. Then I saw this. The price is a little steep for a simple part like this. But it fits perfectly and after about 15 minutes the driver was back to work and sounds just like new.

Rated 5 out of 5 by from Radian Diaphragm, A Great Driver ProductHere is a great driver product from a well known driver company. This unit sounds incredibly good. Very transparent, handles high power well, vocal definition is superior to most others types out there.You cannot use this with the Altec loading cap, as the connection tabs get in the way. If you can forgo the loading cap, as some tend to do, then these will work with most any Altec small format horn device.The price is well within those that yu find out there and you have the customer service & support that PE is well known for.I used my diaphragms with an Altec driver 902-8T & 511 horn lens. It worked very well with excellent output & clairity- it does not get better than this for the small format horn use!DC

Rated 5 out of 5 by from great diaphragmI bought some much cheaper ones for $30 each on Ebay from Hong Kong. They were so bad-sounding that I ditched them. The Radian diaphragms I bought here are excellent. My altec horns now sound like original equipment.

Rated 5 out of 5 by from Great replacement diaphragm for my 16" Altec horn!Still rockin' with my Heathkit AS-101 after over 40 years thanks to Radian and Parts Express. I have replaced both diaphragms and the 880 hz Altec horns are back delivering the crispness and clarity that I expect. Paired with 15" low frequency speakers (again Altec), they can still shake the walls.One other thing to consider if you're replacing diaphragms in a similar setup. Consider replacing aging crossovers and L-Pads. Tubular capacitors and chokes can't match the performance of state-of-the-art gear. Eminence makes excellent crossovers that worked well for me when paired with Pro-Tech L-Pads.
