{"product_id":"qtx-qr-active-series-8-replacement-driver-4-ohm","title":"QTX QR Active Series 8\" Replacement Driver, 4 Ohm","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThis is a replacement driver from the QTX QR Active Series, built to fit the QR8A active cabinet. It's an 8\" chassis speaker (also called a woofer or bass driver) rated at 4 ohms, made to slot straight into the QR series active speakers when the original main driver needs swapping out.\u003c\/p\u003e\n\u003cp\u003eThe driver uses vented magnets, which help keep the voice coil cooler during longer runs, and it connects using spade terminals for a quick and secure fit. Because it's a like for like replacement, you keep the same sound the cabinet was designed for rather than guessing at a substitute part. That makes it a sensible choice if you run QR8A cabinets and want to get a working unit back in service without replacing the whole speaker.\u003c\/p\u003e\n\u003cp\u003eWe stock this as part of the wider QTX QR replacement driver range, so you can match the correct size and impedance to your cabinet. If you're unsure which driver your model takes, check the impedance and driver size printed on your existing unit before ordering. Fitting is a straightforward job for anyone comfortable with basic speaker maintenance, though we'd suggest disconnecting power and taking care with the wiring polarity when you reconnect the spade terminals.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.35KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e87mm x 210mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSPL @ 1W\/1m\u003c\/td\u003e\n\u003ctd\u003e93dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e55Hz - 8kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoice coil\u003c\/td\u003e\n\u003ctd\u003e35mm (1.35\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e20cm (8\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnet size\u003c\/td\u003e\n\u003ctd\u003e18mm x 100mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnet weight\u003c\/td\u003e\n\u003ctd\u003e0.57KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower rms\u003c\/td\u003e\n\u003ctd\u003e100W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower max.\u003c\/td\u003e\n\u003ctd\u003e150W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance\u003c\/td\u003e\n\u003ctd\u003e4 Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhich cabinet does this driver fit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt's made to replace the main driver in the QTX QR8A active cabinet from the QR Active Series.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the impedance of this driver?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt's rated at 4 ohms, matching the original driver in the QR8A.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size is the driver?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt's an 8\" chassis speaker, sometimes called a woofer or bass driver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does it connect?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt uses spade terminals, so you can fit it quickly and securely to the existing wiring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the vented magnets for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eVented magnets help keep the voice coil cooler during longer periods of use.\u003c\/p\u003e\n","brand":"AVSL","offers":[{"title":"Default Title","offer_id":53272101716235,"sku":"902.528UK","price":18.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/902528UK_0.jpg?v=1785048610","url":"https:\/\/niori.co.uk\/products\/qtx-qr-active-series-8-replacement-driver-4-ohm","provider":"Niori","version":"1.0","type":"link"}
