The adapter i'm replacing has the following specs. will this adapter work? input: ac 100v~240v, 50/60 hz output: dc15v~1.5a

Yes it should work. Your old one was 15 volts and this one is 15 volts. The old one put out 1.5 amps and this one puts out 2 amps. More power so it's at least as powerful as the one it's replacing and having more amperage is OK.

Is the pin size compatible with Harmon Kardon Multimedia speaker 15v 1.1amp?

No. The plug does not fit Harmon Kardon speaker P/N 01D430, even with the included different adapter sizes.

What is the polarity of the plug?

The outer is Negative and the inside is Positive

I have a turntable that says it takes 15v dc in, and the manual says it's 4.5watts consumption. seems that's 300ma. will this work for that?

Yes 15vdc ÷ 4.5watts = 3.3 amp, this power supply charger can handle the load more than enough.
