Thank you for comment Gerry.

Did you mean that A400's should be placed as far apart in the room as possible whereas T1030 can be placed closer when you mentioned the boundaries?

Also, should both pairs be toed in or just place front facing?

Thanks

The A400 isn't meant to be be "pulled away" from the wall behind it. Doing so will weaken the bass considerably. Nor was it designed to be "toed in" (which pulls the speaker slightly away from the wall behind it. The T1030 can be used near or close to walls, but also several feet away to minimize wall reflections which can slightly "blur" the stereo image. You can also toe theT1030's in..also to minimize blurring the "first arrival" stereo image.

I personally believe that speaker spacing is best between 6' to10' apart depending on size of the room (for either system) and how far you can sit behind the speakers and still have good imaging AND good, smooth bass at the listening location. There is no hard/fast rules to exact distance..depends on the room and aesthetics.

Dear Mystery. Regarding post #11. The A400 was "before my time" at BA. It was Andy Kotsotas's VERY FIRST SPEAKER when he founded the company.

I did listen briefly to the A400 flagship, but did not use it as "a reference" while doing the design work for the T1030. Note that they are VERY different speakers as far as loudspeaker placement is concerned.

The  A400 was designed to tackle the "Allison effect" by having the woofer very close to all the boundaries (for smoothest bass into the room). The wide baffle minimized diffraction from the cabinet edges. For the system to work as intended, it must be placed against the wall.

With a smaller "footprint", the T1030 was designed to give the user greater flexibility in it's room placement options. When I "voiced" the T1030, I gave particular attention to it's "nearfield imaging" capabilities. I don't know whether Andy did the same for the A400. I do know that the A400 was/is highly regarded in the audiophile community. For all I know, the  A400 could "image" as well or better than the T1030.

Again, I have not "A-B 'ed" the two to see which is "better". IMO, really pointless to do so because it's really like compairing apples to oranges. I've found that when comparing two systems that are competantly designed, the differences heard can be attributed as much to the recordings and room acoustics as to the speaker themselves. Sometimes, these two variables can SWAMP differences in "design philosophy". Which is why I don't pay much thought to exotic (expensive) cables and such.

todtubbi.... "The T930's make a very nice 2.0 system for my big screen tee-vee, but I want to upgrade to 5.0 (I'm thinking that with the T930's I shouldn't need a sub--do you agree?)" 

As good as the 930's bass is for music,"Movie Bass" is a whole other animal. It can't hurt to add a powered sub for "home theater". I personally use a Hsu Research model with fantastic results.

Hi d-rok,

 

I know this is a very old post but wonder if I can ask a question.

 

What kind of sound would one expect with the Lower Mid driver?

 

Would you get bass reproduction through them?

 

I recently purchased a pair of AR9 but not getting much bass through the LMR.

 

Best regards,

David.

The LMR driver is deliberately filtered below 200 hz thru the crossover to NOT reproduce bass. This is done to prevent bass frequencies from interfering with the cleanest possible reproduction of program material in the lower mid range frequencies (like vocals). Introducing bass into this driver would defeat the purpose of having the driver in the first place (lack of intermodulation distortion from bass-heavy material).

David. The LMR should NOT produce "bass" (it is for the "Lower Mid Range"). However, if there is leaking from the LMR into the main woofer enclosures, this could reduce  "mid-bass"  output from the main 12" woofers.

What I would do (if possible) is this: drive ONLY the woofer section of a SINGLE speaker system using a single track of music containing bass. When doing this, place this speaker system into a marked location. Mark the listening postioning when doing your evaluation. Remember the settings of your electronics. Evaluate and remember the amount and "quality" of bass being reproduced for this listening/speaker location combinition.

Then take the OTHER speaker and place it in the SAME location as the first. Be sure to also use the same LISTENING location as for the first speaker. Also, be sure to use the same musical track, amplifier channel and electronic settings as for the first speaker. You should get virtually identical performance results from each speaker. If a noticible audible difference exist between the two systems, then at least one speaker system has "woofer issues".

It's also possible the woofer surrounds may have seperated from the cone (if the adhesive wasn't applied properly when refoamed). Or the woofers are not seated tightly against the cabinet. Either condition will reduce bass output.
