Hello all, I am thinking about the upgrade. I have 2 pb2isd's right now and i am going to upgrade. I have a theater room that is 22x17x8. I know that I "do not need" anymore than what I have right now but you know how that goes. My options are to sell the 2 pb2isd's and get 2 b4plus's or either add 2 more pb2isd's. Going with 4 isd's would be much cheaper, but would it be possible to get all four of them to sound right together? Also if I could get them all together properly, how would they compare to 2 b4-plus's? Any help would be great. Thanks guys.

Yes, 2 B4+.

4 of the smaller ones will get you output, but 2 of the bigger ones get you output *and* low freq extension.

As far as integration, I think that more subs are usually easier to integrate than fewer. Some white papers over on Harmon Intertnational's web site about that.

i would question whether you could do 4 of them, one crossed over speaker level with each main and each surround... this would give the best HT integration.

BUT, if you did 2 B4+'s, you could do them as main preout subs and get a similar result.

A much more even comparison would be 4 cylindar subs vs. the B4+. Obviously the ability to not have to sell your current subs is easier. With 4 subwoofers you would have a nice option of placing the subwoofers in a few locations. Or just keep all 4 in a corner. Of course one single subwoofer may be easier to set up and locate aesthetically.

Some considerations.

I'd also vote for the 2 B4's only for simplicity sake (and if you can, place them symmetrically so they do not create cancellation. Harmon Kardon web site not withstanding, getting 4 subs to integrate is NOT easy.

At least that was my experience as I had 2 B4's and 2 PB2+'s and the 2 B4's alone sound (in my room) much better

Might I be so bold as to suggest an alternative? What about either dual PB2-Ultras ($2,550 each delivered) or dual PB2-Plus subs ($1,298 each delivered)? One thing to note is you could pick up either dual PB2-Ultras or four PB2-Plus subs for the price of two B4s. And that thought is just sick. Better bring in a structural engineer to verify the structural integraty of the house.
