Special HF Application And Ordering Notes -

NOTE 1 -    Special modifications are required to keep the 288B in operating condition. You must send the entire unit in and have us modify and remagnetize the motor structure. The HF diaphragm must also be replaced. Select from one of the following aluminum diaphragms:

                    20221     Aluminum     24 ohms

                    23834     Aluminum     16 ohms

                    23763     Aluminum       8 ohms

                    25884     Pascalite™     8 ohms

                    25885     Pascalite™   16 ohms

NOTE 2 - When the original 24 ohm impedance is not required, use the diaphragm manufactured for the Altec Lansing 299-8A, Altec original part #25884 (8 ohms), or the diaphragm manufactured for the Altec Lansing 299-16A diaphragm, Altec original part #25885.

NOTE 3 - For superior HF reproduction, use original diaphragm. If higher power handling is required, but excellent HF frequency response is also needed, use diaphragm #25884 (8 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 4 - For superior HF reproduction, use original diaphragm. If higher power handling is required, but excellent HF frequency response is also needed, use diaphragm #25885 (16 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 5 - ALL older Altec drivers must use a 288/291 or 800/900 Series Conversion Kit in order to be retrofitted with ANY Altec Lansing Diaphragm manufactured after 1983. Every Altec Lansing driver manufactured before 1983 will require one of these kits the first time a post-1983 diaphragm is installed in it.

                                                                                                                                                                               © Great Plains Audio, Inc.

Old-style Diaphragm/Voice Coil Assembly for all Altec Lansing HF Compression Drivers manufactured prior to 1983. If yours looks like this, you must send it in to Great Plains Audio to be re-fitted with new parts, 
or you can buy a new style diaphragm and a conversion kit.

NOTE 6 - For superior HF reproduction, use original diaphragm. If higher power handling is required, but excellent HF frequency response is also needed, use diaphragm #25884 (8 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 7 - For superior HF reproduction, use original diaphragm. If higher power handling is required, but excellent HF frequency response is also needed, use diaphragm #25885 (16 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 8 - Symbiotik® diaphragms are no longer available. If high power handling is required, but excellent HF frequency response is needed, use diaphragm #25884 (8 ohms). For superior HF reproduction, use diaphragm #23763 (8 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 9 - Symbiotik® diaphragms are no longer available. If high power handling is required, and excellent HF frequency response is also needed, use diaphragm #25885 (16 ohms). For superior HF reproduction, use diaphragm #23834 (16 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 10 - For superior HF reproduction, use original diaphragm. If high power handling is required, and excellent HF frequency response is also needed, use diaphragm #26420 (8 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 11 - For superior HF reproduction, use original diaphragm. If high power handling is required, and excellent HF frequency response is also needed, use diaphragm #26421 (16 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 12- Original 4 ohm diaphragms available only by special order. For superior HF reproduction, use diaphragm #34647-4 (4 ohms).

NOTE 13 - Symbiotik® diaphragms are no longer available. If high power handling is required, and excellent HF frequency response is also needed, use diaphragm #26420 (8 ohms). For superior HF reproduction, use diaphragm #34647 (8 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 14 - Symbiotik® diaphragms are no longer available. If high power handling is required, and excellent HF frequency response is also needed, use diaphragm #26421 (16 ohms). For superior HF reproduction, use diaphragm #34852 (16 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.

NOTE 15 - Symbiotik® diaphragms are no longer available. For superior HF reproduction, use diaphragm #34647-4 (4 ohms). Call us if you need advice on the proper selection of a diaphragm for your particular application.
