Engineered for open baffle systems like the Linkwitz LX521 and King Roy kits, it offers exceptional mechanical stability and high power handling with a 4 ohm impedance, making it ideal for audiophiles seeking precise, dynamic low-frequency performance. ## Description Design by Seas 10" Subwoofer L26RO4Y-D0004 This woofer is used in the Linkwitz LX521 open baffle system and the King Roy kit. "There is more to a woofer than its published TS small signal parameters and X-max, derived from mechanical measurements. In the Orion's open baffle, a woofer operates in the large signal domain; and its distortion, dynamic stability and limiting behavior determine the sound. An open baffle is the most demanding and difficult environment for a long throw woofer." -- Siegfried Linkwitz: To meet these stringent demands, the L26RO4Y subwoofer builds upon the already excellent chassis, magnet system, cone, and surround of our L26ROY. An all new FEA designed spider and 4 layer voice coil wound on a stiff glass fibre former have been employed, resulting in a driver with ultra long throw, very low distortion, and extremely stable mechanical operation under all conditions; including open baffle systems. The low Qts and Fs are ideally suited for active open baffle bass systems, but the L26RO4Y can also produce excellent results in enclosure based subwoofer and multi-way systems. Extremely stiff and rigid aluminium cone gives tremendous bass precision. The cone and the long throw low loss rubber surround show no sign of the familiar cone edge resonance and distortion associated with soft cones. Lead-out wires symmetrically stitched to the spider to avoid resonances. Total suspension designed to assure stability for extreme excursions. 4-layer, extremely long, high temperature voice coil wound on an glassfiber voice coil former gives a high power handling capacity. Cu-cap around the pole pieces reduce non linear and modulation distortion and increase overload margin. Extra large magnet system provides high efficiency and low Q. ## Features - Designed by Seas 10" Aluminum Cone Subwoofer - 4 Layer voice coil version with lower Qts - Designed for use in the Linkwitz LX521 Open Baffle Kit - Also used in the King Roy kit. - Will not work in conventional sealed or vented systems without DSP correction. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ZYTKRRI | | Antenna Location | Mechanical | | Audio Output Mode | Surround | | Brand | Seas | | Compatible with Vehicle Type | Car | | Control Method | Voice | | Controller Type | Voice Control | | Is Waterproof | FALSE | | Manufacturer | Seas | | Model Name | L26RO4Y | | Model Number | L26RO4Y | | Mounting Type | Flush Mount | | Speaker Type | Surround Sound, Woofer | | Subwoofer Diameter | 10 Inches | ## Product Details - **Audio Output Mode:** Surround - **Brand:** Seas - **Model Name:** L26RO4Y - **Mounting Type:** Flush Mount - **Speaker Type:** Surround Sound, Woofer ## Images ![Seas Designed L26RO4Y 10" Aluminum Cone Subwoofer, 4 Layer VC, 4 ohm (D1004-04S)- Each - Image 1](https://m.media-amazon.com/images/I/41wNizANzIL.jpg) ![Seas Designed L26RO4Y 10" Aluminum Cone Subwoofer, 4 Layer VC, 4 ohm (D1004-04S)- Each - Image 2](https://m.media-amazon.com/images/I/51vUAIcK+eL.jpg) ![Seas Designed L26RO4Y 10" Aluminum Cone Subwoofer, 4 Layer VC, 4 ohm (D1004-04S)- Each - Image 3](https://m.media-amazon.com/images/I/51VnYqP7k-L.jpg) ![Seas Designed L26RO4Y 10" Aluminum Cone Subwoofer, 4 Layer VC, 4 ohm (D1004-04S)- Each - Image 4](https://m.media-amazon.com/images/I/512o91fwd1L.jpg) ![Seas Designed L26RO4Y 10" Aluminum Cone Subwoofer, 4 Layer VC, 4 ohm (D1004-04S)- Each - Image 5](https://m.media-amazon.com/images/I/41OMG1GVy3L.jpg) ## Questions & Answers **Q: What is the correct enclosure volume for this 4 layer driver with a passive radiator?** A: You could use about 1.0 to 1.25 cubic foot with the passive. No additional weight needed. The 2-lay L26ROY in a 1.5 cubic foot box also looks great. **Q: The seas l26ro4y( 1004) with 4 layer vc is less efficient than the 2 layer vc model (1001). can a plate amplifier with dsp helop offset this?** A: A 4 layer voice coil has more wire and is heavier, adding to the drop in efficiency. You can make many adjustments with a DSP. Output, boost, delay, many things. You will probably find you need to boost the low end output on this woofer. **Q: Would this be ok for a sealed passive box in a car?** A: Yes, but you will probably need to use an equalizer or bass boost to extend the low end. Using this woofer in 0.6 cubic foot sealed box without any boost will give you an F3 of about 70Hz. Using this sealed box in a vehicle with 6dB of cabin gain will get down to 30Hz.
