Ideally, bipolar speakers radiate into 4-pi space across the frequency band so baffle step isn't an issue. Even a castle arrangement likely wouldn't need BSC.

My listening to a 10.2 MLTL indicates there is minimal adjustment needed for a monopolar version.

That's why I ask. The additional driver may fatten the sound to much. The bass performance usually isn't something people find lacking with the alp10.

My only conclusion is; they must sound amazing!

never apologize for your aesthetic taste,

yes they are rather more bother than a simple MLTL of same approx size and tuning

yes, they do offer some benefits in terms of more control from mid-bass on down, at the sacrifice of less slam / weight

TUX:

agreed on the A10.2 - for my taste it has more than adequate response without any BSC EQ - 2 might very well be too fat in a less than critically damped enclosure -

Personally, I'd be more inclined to try 7.3s in a Castle, or wait for the new 8

It'd be only a little bit silly and expensive to go for dual MAOP7s

What am I saying, it'd probably be stupid good - expensive yes, but far less than the premium meal and adult beverage upgrade package on a 10 day Caribbean cruise , or the HST on this spring's sundeck renos ( motorized awning, staircase, vinyl and glass railing system.) That's a $20,000 check mrs B has no trouble writing - go figure.

You crack me up Chris, ouch. Hopefully it'll have a nice desk system for summer tunes.

Yep, Chris often cracks me up, but I never have anything quite as witty to reply with, so I just giggle by myself.

Re: the original topic; I think I could handle the "fat" of an Alpair 10.2 Castle. The need to attenuate bass is more attractive than never having enough.

Granted, the bass of the single Alpair 10.2 is impressive, but (again at the risk of offending someone) it is not very balanced or well controlled so far. I wouldn't call it a one-note wonder, but there are tracks that just sound completely wrong on the bass. Example: U2 - "One". The bass line is a complete mess on my Pensil 10.2s.

Woke up at 3am with terrible sinus pain, and a single thought in my head: "my pensils have a null."

You see, the bass it great, it is just almost completely missing a note or two...

Am I correct to suspect standing waves due to sub-optimal bracing implementation?

...But I should probably take this over to my build thread...

Likely speaker placement not bracing. But yes, it's very likely that's your bass issue.

I hope that isn't the case, because a) the speakers pretty-much have to remain where they are and b) my microTowers have no issues with bass sitting in the exact same position.

I'm going to run some sweeps after work today and see exactly where the problem is. Will run sweeps of the microTowers in the same position. Probably will run sweeps with the nanoTowers, too, as I have been meaning to do that for quite some time.
