You could always use the high level speaker inputs for the sub.

I helped Jack setup his main room and second zone. When he first got the M60's he was complaining of the speakers sounding too bright and wanted to return them.

I convinced him it was his room acoustics. We move the M60's into his main home theater room and they sounded great and just how we both expected them to sound. That room happens to be smaller and carpeted as well as a little more closed off. But move them into his great room and the sound really gets lost. He has hardwood floors everywhere fully opening up into other rooms which are all tile. Lots of windows and not a lot of wall treatments.

Before you go the Def-Tech route, try a few things and give us some info. First, if the room is bigger, and bass is the issue, I don't think you can assume the Denon 700 is supplying plenty of power. But before we let those worms out, try this: Put the Denon in your second room, and test the speakers with a clean short run from the main amps, not the surrounds/zone 2. Mess with Bass and Treble settings to see how much you can gain from the best possible set up and locations. If that set up is not good enough, you know you need to make big changes and can skip all the second zone issues at this point.

If that sounds good, then you have options. Increase the power to zone 2 with a second cheap AVR or buy a stand alone amp (with tone controls). If you notice improvement but still not enough bass, then a separate sub would be the way to to, but you have to work out the zone 2 issues with that. Adding a built-in sub (like Def-Tech) may be a good option in your situation, but be aware, most of what I (just me, don't freak!) have heard and read on the lower-end Def-Techs with built in subs does not cause me to believe you will find your answer there.

Most likely, in my opinion, you would be best served by a sat/sub setup. Smaller speakers higher up to avoid as many reflections, tied to a solid sub to move the mass of air needed to replicate natural sound even at lower levels.

On a side note, he has the Orb Audio People's Choice system in his main zone. They sound very good. I'll be interested to hear any comparison of Orbs vs the new Axiom Accents when they are released.

He said he was going to try the Orb Super 8 sub in the other room with the M60's and see if a sub really helps. The Orb Super 8 may not help as much as a better sub, but he should have an idea if a good sub will solve the big room issue.

Changing out speakers is not going to solve high frequency reflection issues. If you have a lot of flat bare surface, you should consider some sort of treatment. It may be as simple as carpet and some wall hangings at first reflection points.

If this is a music only system, you don't need a huge sub. A capable 10 incher will reach down into the 30Hz range quite nicely.

From my present perspective, the A1400-2 and the M80s would great in that room, sub not needed, not exactly a budget system.

Hi jackmlin,

Welcome. That's an enormous room--just under 20,000 cu. ft. You're going to absolutely require a big subwoofer. I'd suggest at the least, the Axiom EP500 or EP600, and preferably a pair of M80s. I assure you the deep bass from a pair of M80s, properly powered, with at least one EP500 subwoofer will not be "lost" or overwhelmed by the big space.

You're also underpowered; consider an outboard power amplifier with at least a clean 200 watts per channel.

As others have suggested, some simple room treatments will help a lot--by "treatments", some area rugs and perhaps some wall hangings.

Regards,

Alan

Thanks everyone.

I moved the sub for my home theater to the big room to try it out. It improved the sound considerably although still not as good as having just the M60s in a small room. Since I was hearing plenty of bass using the sub, I came to the conclusion that the room size/shape is simply not conducive to very good sound. However, I will get a matching sub like EP175/350 for my M60s. Thanks again for your feedback.
