    Super cheap 4675a's

    Would these be appropriate for a normal sized living room? I would have to buy three and only need two so I would end up with an orphan. As you might guess, I am wifeless at the moment.

    We've got a set of 4270D's at our family cabin. Same bass cabinet and HF driver I believe. Smaller horn. These are playing into a very big room with 20+ foot ceilings, and believe me they have the sensitivity and headroom to blow the back walls out with a 70 watt tube amplifier.

    Very smooth, with ample bass, and highs that are extended enough that I don't feel cheated. Wonderful speakers for the money.

    I've considered dropping the 4270D components into a set of old S8R cabinets to make them more presentable for a living room.

    I'm curious what they're asking for the 3 speakers?

    I am not sure, but I believe You are talking about 'theater series speaker 4670' ( 2 x 2225H + 2445 + 2360 ). I can imagine the use of the mentioned after some hard works on appropriated network (either on 2 or even 3-amplification with electronic network, or passive, where experience with 4350/55 or Ev2 DD66000 would be good starting point).

    May be helpful:

    or for 2445 only, good starting point can be L200B network :

    or as our member toddalin in the post has suggested:

    but for the LF section (one of the two 2225H) for the so-called "helper bass unit" some ideas in the:

    http://www.audioheritage.org/vbullet...l=1#post301423

    where LF1 denoted 'helper bass unit",

    may the rest can be as in N4671

    Yes that is the correct model number. My mistake. The system sounds pretty good already with the stock passive crossover.

    I don't have owners manual at home, and am not sure it would even have the schematic for the crossover network. Sorry.
