Designed as a direct swap for standard 1 3/8" mounts, it includes four mounting screws and is ideal for professional audio setups seeking enhanced stability and durability. ## Description Upgrade your subwoofers! Replace existing 1 3/8" Sockets with the SSA20M Threaded speaker Adapter. Designed to be a direct replacement for most socket mounts; simply remove and replace. M20 threading provides a rock-solid, wobble-free connection between the subwoofer and compatible speaker poles. Perfect for use with the SS7746 adjustable subwoofer shaft. Review: This is a very sturdy piece of steel. You can use this "Top Hat" to replace the 1 3/8" smooth socket you get with most subs. This is threaded - most are not. When they are not threaded then the pole that fits into this socket actually has too much play in it. Extend the pole up about 3 feet and put a PA cab on top of it and it makes the Leaning Tower Of Pisa look straight. The pole will flop all over the place and the speaker atop it will be all askew and look really stupid, like its about to fall over. Inserting this speaker pole mount allows you to use a threaded pole that screws into it so it doesn't wobble. Now, this mount DOES NOT WORK with the stock ElectroVoice ZXA1Sub, which has a THREE-HOLE mount with a smaller outer diameter than this one. The EV Sub's hole is recessed so this doesn't fit into it, but luckily it fits OVER it. You'll need to drill new holes and by bolts and T-Nuts. I wouldn't use the wood screws that this mount comes with - they may tear out of the wood if the PA Cab atop the pole is jossled. It was regardless very easy to install and all the screws and t-nuts are available at your local hardware store for under $10. Works like a charm. I will buy more of these! Good product, good price and fast shipping! -UPDATE: I gigged with these last weekend and they are as solid as a rock! I'm happier than a clam at high tide! One more thing, as an afterthought, you probably want to protect the thread on the poles that fit into these sockets. Again, take a pole to your local hardware store and buy some rubber "feet" - the kind they put on the bottom of metal tube chairs and such. The Ace Hardware part#/SKU is 51245 - it is a solid white rubber "foot". I paid $2.49 for a pack of four. I drilled a hole through mine and put a cord through it and attached it to the pole so that when I remove them from the pole they're still tied to the pole and don't get lost. You don't want those threads to get damaged, or even dirty, while transporting and storing them. -G Review: Very sturdy. Works well on my Mackie SRM1801. ## Features - Replaces existing 1 3/8" sockets - M20 threading provides wobble-free connection between the subwoofer and compatible speaker poles - Includes four mounting screws ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00FKY86V6 | | Best Sellers Rank | #138,714 in Electronics ( See Top 100 in Electronics ) #1,374 in Audio & Video Speaker Accessories | | Brand Name | OnStage | | Color | Black | | Customer Reviews | 4.7 4.7 out of 5 stars (310) | | Global Trade Identification Number | 00659814101504 | | Included Components | 4 mounting screws | | Item Dimensions | 15.2 x 5.1 x 15.2 centimeters | | Item Type Name | Cabinet Adapter | | Item Weight | 227 Grams | | Manufacturer | On-Stage | | Manufacturer Part Number | SSA20M | | Material Type | Alloy Steel | | Model Number | SSA20M | | Mounting Type | Tabletop Mount | | UPC | 659814101504 | ## Product Details - **Brand:** OnStage - **Colour:** Black - **Item dimensions L x W x H:** 15.2 x 5.1 x 15.2 centimeters - **Item weight:** 227 Grams - **Material:** Alloy Steel ## Images ![OnStage SSA20M Speaker Mount Adapter with M20 Threading - Image 1](https://m.media-amazon.com/images/I/51dMRGtw80L.jpg) ![OnStage SSA20M Speaker Mount Adapter with M20 Threading - Image 2](https://m.media-amazon.com/images/I/51mLWc4rS7L.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***Y on 29 March 2015* This is a very sturdy piece of steel.
