3 X Quested LT20 Loudspeaker Plus 3 X Quested AP1550 Amplifier With Filter Cards

1230 Views 6 Replies 2 Participants Last post by  Bassfeen
Hi All.



Fully Active 3 Way Studio, Production, Home Theatre Speakers. These are built for High SPL with out sacrificing Sound Quality. Amplifier, Filter Cards and Speaker are all designed by Roger Quested.


I also have the Amplifier for these AP1550 with Fillter Cards Installed, Each Amplifier is configed in a Biamped Mode. I can Split the package if you dont require
the amplifier but highly recommend them as this was designed and configed for the LT20


The tweeter can be changed on these to give the speaker a shorter throw distance if required!!


What does the package Include:

3 x LT20 Speakers (With Original Box)
3 x AP1550 Amplifiers (Each Channel is Fitted with a Filter Card, One Channel for High& mid, the other for Bass)


Filter cards can be removed and you can run Electronic Crossover if you want too. However the Filter cards were installed
due to there natrual sound higher fidelity (Quested Opinion)



I can ship world wide by Fedex Air
