sir vic,
any idea on what center and surrounds would match an altec lansing 619-8A and a MS 409 subwoofer? currently using a yamaha rxv450 receiver.
I made a research and found Altec Lansing 619-8A to be a duplex ceiling mount speakers. These speakers are for industrial application like installation for auditorium, church, etc.
Of course, you can use these speakers for HT surround initially. However, after a while, you really have to replace them for a pair that will be timbre matched with other speakers.
First of all, you need to determine the size of speakers to complement the size of your room. If you have a small room, you may opt for this bookshelf package: Mission front MV-4 at P7700. and Mission center MV-C at P6700.
If you wish to have more dynamic presence in music and movie, you may opt for a floor-standing front like MV-6 at P12,300.
Mission delivers warm sounds. It will complement well with Pioneer receiver that delivers bright or forward-sounding.
