No. 5957 \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\t\u003cb\u003eCharacteristics and sound properties\u003c\/b\u003e \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tIt is well-known that there are two types of loudspeakers: hi-fi speakers that produce the most accurate, unaltered sound possible, and disco or musician's speakers, where the top volume level is of the utmost importance. These volume levels are normally only possible with horns but these often cause coloration of the sound. The MONITOR 890 MK III was designed specifically to combine the best of both worlds. In the mid-range, we use a driver \u0026amp; horn unit which is so dynamic and produces such undistorted music, that many a horn-disparager has had to admit that this is simply unbelievably \"different\". Two excellent quality woofers, TIW 300 8 Ohm, mounted in the 180 litre vented cabinet, generate a bass sound pressure that is physically tangible, as you have experienced with concert speakers. Combined with the first-rate TL 16 H 8 Ohm high-range horn, we have created a loudspeaker system that breaks down the previously unbridgeable barrier between the hi-fi and the professional speaker. \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tThe output levels of the mid-range driver and tweeter can be adjusted to the requirements of the locale using output controls. We recommend, initially at least, the following level settings: tweeter: -4 dB; mid-range: -4 dB. These can, of course, be adapted to suit the specific acoustics in the room and personal preferences. \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tThanks to the added impedance linearising unit in the crossover unit, the Monitor 890 MK III is now even better suited to use with critical amplifiers (e.g. tube amplifiers). \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\t\u003cb\u003eConstruction\u003c\/b\u003e \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tThis octagonal cabinet looks more complicated than it really is. All the chamfers are cut at 22.5° except two (at 45°). When you set up the saw, it is best to cut fractionally over 22.5° to ensure that, on the outside, all the chamfers are really airtight. \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tFirst cut the required cut-outs in the boards, which have already been cut to size. The two circular ones for the bass loudspeakers, the square opening for the tunnel and the two for the level controller. \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tNext, build the main body without the base and top. You will need plenty of sticky tape to hold the joints together when gluing the side panels. The parts for the tunnel, the four stiffeners on the side panels and the vertical stiffeners (50 mm wide) on the front baffle then need to be shaped to an exact fit. The base then has to be shaped to fit exactly in the completed main body, since it is hardly possible to build the body with millimetre accuracy. Next, glue the vertical stiffeners to the base and the stiffener between the baffle and the rear panel. \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tThe top with its cut-out for the terminals for the high- to mid-range is then shaped to fit and glued in position. The two crossover circuit boards are attached to the rear panel opposite the lower bass speaker drivers. The wiring to the horns need not be heavier than 1.5 mm2. From the terminals to the circuit boards and to the woofers, use wires with a cross-section of 2.5 mm2. \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tThe twin terminal unit for connecting the mid- to high-range horns is fitted in the square cut-out in the top. The two gold-coloured jumpers have to be removed to do this. \u003cbr\u003e\r\n\t\u003cbr\u003e\r\n\tThe mid-range horn is placed on top of the cabinet on its three straight-sided feet. The tweeter is mounted on the wooden base supplied and is placed on top of the mid-range horn, towards the rear. The position of the two horns is crucial to the acoustics and, for this reason, they should be positioned as shown in the drawings.\u003c\/p\u003e\r\n", "published_at":"2018-10-11T14:40:58", "created_at":"2018-10-11T14:40:58", "vendor":"Visaton", "type":"Visaton - Loudspeaker Kits \u0026 Accessories", "tags":["Type_Large Floorstanding","Visaton - Loudspeaker Kits \u0026 Accessories: Large floorstanding"], "price":425495, "price_min":425495, "price_max":425495, "price_varies":false, "compare_at_price":null, "compare_at_price_min":0, "compare_at_price_max":0, "compare_at_price_varies":true, "all_variant_ids":[15301429952579], "variants":[{ "id":15301429952579, "product_id":1676695928899, "product_handle":"visaton-monitor-890-mk-iii-price-per-pair", "title":"Default Title", "option1":"Default Title", "option2":null, "option3":null, "sku":"5957", "requires_shipping":true, "taxable":true, "featured_image":null,"image_id":null, "available":true, "name":"Visaton MONITOR 890 MK III, Speaker Kit (Pair) - Default Title", "options":["Default Title"], "price":425495, "weight":999990, "compare_at_price":null, "inventory_quantity":0, "inventory_management":null, "inventory_policy":"deny", "inventory_in_cart":0, "inventory_remaining":0, "incoming":false, "next_incoming_date":null, "taxable":true, "barcode":null}], "available":true,"images":["\/\/impactaudio.co.uk\/cdn\/shop\/products\/730c2048d8b877d0b237ffddf0150971.jpg?v=1539265259","\/\/impactaudio.co.uk\/cdn\/shop\/products\/25e7d5d8e2b06412c0c332b936bd0a45.gif?v=1539265259","\/\/impactaudio.co.uk\/cdn\/shop\/products\/25069dd82f9e3a49a446e53aee069f9d.gif?v=1539265259","\/\/impactaudio.co.uk\/cdn\/shop\/products\/0c3ad89fef3e4cd18831a4d489881265.gif?v=1539265259"],"featured_image":"\/\/impactaudio.co.uk\/cdn\/shop\/products\/730c2048d8b877d0b237ffddf0150971.jpg?v=1539265259", "options":["Title"], "url":"\/products\/visaton-monitor-890-mk-iii-price-per-pair"}
