It had (and still does have) a 10\" active and 10\" passive driver. What made the subwoofer so unique was its size and power, accomplished by a long throw driver and an amplifier capable of several thousand watts. Although long throw drivers are not unique, fitting a kilowatt power amplifier in such a small enclosure was, at the time. Since then, just about every subwoofer manufacturer has designed similar subs. To this day, everyone is amazed at the amount of low frequency sound that comes out of these small boxes.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan style=\"font-family: Arial;\"\u003eJunior's muscle\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-family: Arial;\"\u003eThe 10\" was followed by a 12\", and now, the\u003cstrong\u003e 7\" Junior\u003c\/strong\u003e, in a 9\" enclosure. No one is saying that the Junior will take the place of an 18\" sub in a large box. But, that is not its function. The Junior is for a small home theater setup, for example, in an apartment or student's dorm room, where your mains and surrounds are bookshelf speakers. On the other hand, this 7\" subwoofer makes toast out of any other little sub of the conventional variety. I measured a 1\" throw at maximum output using a sine wave generator at several low frequencies. No conventional small subwoofer will do that.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-family: Arial;\"\u003eAlthough the specifications state that it has a 1,500 watt amplifier, you will never need that much power, but the amp is indeed capable taking into consideration its design. With typical use, you can figure on about 300 watts or so, when it is cranking at deep frequencies.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-family: Arial;\"\u003eThe rear panel of the Junior has everything you could possibly want. Line-level input and output jacks are gold-plated. Speaker-level inputs and outputs are five-way binding posts. Potentiometers let you control volume low-pass frequency including a setting for crossover bypass, and continuously adjustable phase. For the low-pass, 65 Hz is marked \"Normal\", and for phase, 90\u003csup\u003e0\u003c\/sup\u003e is marked \"Normal\". These are merely starting points, from which you can make adjustments to fit your own needs. An LED indicates power on or standby, so there is no need for an on\/off switch. The AC cord is detachable.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-family: Arial;\"\u003eThe output of the Junior is remarkable. A measured, at maximum output, 108.5 dB at 50 Hz, 106.5 dB at 40 Hz, 106 dB at 31.5 Hz, and 96 dB at 25 Hz.  For its size, this is astonishing. It was really quite clean too, even when cranked to the limit. That brings up one feature, which is the Junior's limiter. With early models of the Sunfire Subwoofer, I could get it to clip. \u003cspan style=\"text-decoration: underline;\"\u003eNot so with the Junior\u003c\/span\u003e. Once its limits are reached, further adjustments of the volume control don't change the output. This is a great feature because it will protect the driver, the amplifier, and also prevent that knocking sound you get when an amplifier clips hard in a subwoofer.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-family: Arial;\"\u003eWe also measured substantial output even at 20 Hz, but I could hear a great deal of harmonic distortion, so this output does not count. Practical limits of the Junior are around 25 Hz, which is fine for most films and music. Orchestral music sounded \u003cstrong\u003e\u003cem\u003equite\u003c\/em\u003e\u003c\/strong\u003e acceptable, as long as you don't expect it to do the kind of thing the big subs will do. But, as stated, that is not its purpose. The Junior takes up less than one cubic ft... that's almost laughable for a bass driver this potent. Totally gone through and performing marvelously. Just a killer little sub that is as musical as it is muscular. Fabulous condition and a super rare unit.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan style=\"font-family: Arial;\"\u003eDemos are always encouraged at the Andover shop.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cem\u003e\u003cstrong\u003e\u003cspan style=\"font-family: Arial;\"\u003eBob Carver Sunfire Pure Subwoofer Super Junior: $399.00 plus sales tax and shipping when applicable\u003c\/span\u003e\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Holt Hill Audio","offers":[{"title":"Default Title","offer_id":43292434759747,"sku":null,"price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2197\/6387\/files\/PhotoMay222026_30036PM.jpg?v=1779480255","url":"https:\/\/holthill.com\/products\/bob-carver-sunfire-pure-subwoofer-super-junior-jaw-dropping-low-end","provider":"Holt Hill Audio","version":"1.0","type":"link"}
