Проблемче с едни Монакор'и

Мнениеот slaff » 16 Фев 2011, 21:09

Привет,
Въпроса ми е главно към Радо, но всеки с полезно мнение ще е добре дошъл...

Та, едно приятелче има 2 широколентови монакор'а 5" :
1:
РЕГИСТРАЦИЯ или ВХОД за пълен достъп. РЕГИСТРАЦИЯ или ВХОД за пълен достъп.
РЕГИСТРАЦИЯ или ВХОД за пълен достъп. РЕГИСТРАЦИЯ или ВХОД за пълен достъп.

2:
РЕГИСТРАЦИЯ или ВХОД за пълен достъп. РЕГИСТРАЦИЯ или ВХОД за пълен достъп.
РЕГИСТРАЦИЯ или ВХОД за пълен достъп. РЕГИСТРАЦИЯ или ВХОД за пълен достъп.

Идеята ни е да сложим фазови палци, затова сме и изрязали капачките.
Проблема е, че имаме сериозно разминаване на АЧХ във високочестотната област между двата драйвера.
На снимките се вижда че на драйвер 1, високочестотния конус е 'хванат' леко на криво, и е с по-ниско ниво, спрямо на драйвер 2.

Ето и АЧХ с фазово палче, защото се вижда по-добре разногласието между двата:
РЕГИСТРАЦИЯ или ВХОД за пълен достъп. РЕГИСТРАЦИЯ или ВХОД за пълен достъп.
Драйвер 1 -тъмно син, драйвер 2-св.син

Ето АЧХ и без фазов палец:
РЕГИСТРАЦИЯ или ВХОД за пълен достъп. РЕГИСТРАЦИЯ или ВХОД за пълен достъп.
Драйвер 1-червено, драйвер 2-лилаво

Гледайте измерването само във високочестотната облас.
Как можем да ги 'оеднаквим' ?

Може да се уеднакват само с отлепване на двата конуса, евентуално претегляне на масите им и уеднаквяване при нужда, промазване и залепване в правилно положение с по-подходящи лепила. С тази процедура не само, че ще се уеднакват, но и ще се подобри излъчването им във високочестотната област, ще се разшири честотния обхват.

Кофти...ако махнем ВЧ конусите, какво би се променило в АЧХ?...горе долу?

Ще станат едни широколентови среди, свирещи до около 10-12 килохерца в най-добрия случай.
Не ти го препоръчвам. Може да се монтира и капачка със сферична форма, но трябва да е лека и здрава. По-добре е вариантът, който съм описал по-горе.
Аз на едни им приготвям точно сферичен излъчавател от хартия, но е специално направен, както и хартията сам си я приготвям. А ти ако искаш, пробвай с топче от пинг-понг, на мястото на ВЧ конуса, ще се учудиш от резултата.

Автора ги мисли да ги ползва така или иначе с някакво туйтърче отгоре.
Целта е да ги оеднаквим максимално, било то и да загубим високите над 10к да речем.
Ще ги борим :)
Благодаря за насоките :)
