From Marten Coltrane to Avalon Isis, Hansen King??

Maxx1973, What amplifier are you using with the Marten? That seems to be an inefficient speaker (300w recommended, 89db, 2.7ohm min). Could that be contributing to the lack of bass?

The Avalon would be a improvement over what you have. The crossovers in the Avalons is what makes them so great. I went from Kharma Midi to Avalon Diamonds and it wasn't even close. The bass is also much cleaner with better definition. Avalon really make the best speakers in the world. Just look at how many pairs were used at CES this year.

Mtdking,

Thanks for your info. Of of curiosity, why are you currently selling your Avalon Diamonds again? Which speaker are you going to replace it with?

Rtn1,

I am using Vitus as amplification. I think it should provide enough power, but yes I agree, it's not an easy speaker to drive.

I am not sure about the power ratings for Vitus. However, I would not think twice about putting 600-900+ watts at 4 ohms onto the Marten.

For the Isis in a large room, with few exceptions, I would be looking at 400+ watts into 4 ohms as a minimum.

Other tricks to increase bass would be in the cables. The power cords on the source have the largest effect, followed by speaker cables and interconnects, followed by power cords on the amplifiers. Elrod power cords have a striking effect on the bass.

You have great speakers. All great systems take some time to build and refine.
