Amplifier advice from Ohm Walsh 100 Mk. II owners

I think either amp should work well with either MicroWalsh or 100. I'd try each and see and then go from there if needed.

Again, make sure these are the right size for your room based on the model to room size mappings on the OHM site. 100s will do better in a larger room than Micros.

In teh case where the OHM Walshes are undersized for the room, even in the case of Micro Walshes, adding and integrating a good subwoofer later if needed is a good way to make up the difference in lieu of going to a larer model.

Also, some report good results using even tube amps with the OHM Walshes when subs are used to offload the work needed for the low end. So adding a sub and offloading the work for teh low end to it is another option for weaning better performance out of any given amp.

Mapman, any sub recommendations to go with the 100s?

HAven't tried subs with 100s (no need in my 12X12 rooms that I use them in).

Choice of sub will also probably largely depend on room size.

Bigger room-> bigger sub with more power needed. That usually always is the case.

The line I am most familiar and comfortable with from having heard sound good in higher end dealer systems in general is Rel. That is a popular line with the audiophile crowd in general. I am sure there are many other good ones though.

In general, 2 subs are usually better than 1, but 1 can work well especially if big enough and you have flexibility with locationand used with more full range speakers to start (like the 100s) where the crossover frequency need not be too high. Higher frequencies are more directional sounding in nature so a lower crossover point is generally better especially if using just one sub.

Personally, I would rather right size the OHMs to the room if possible rather than go the sub route, but that is just me. You might defer some cost adding a sub later, but not really save much if any money in the end once you do.

Plus the Walsh drivers are full range up to about 7Khz or so, which is part of its magic in terms of coherency. Crossing over to a sub might intrude on that.

Thanks for the info! I believe Martyk1 has used the 100s with subs in a larger room, but it's beginning to look like my 100s will end up in a 12x12 room, so it's unlikely to be an issue. I thought they sounded very good in my larger room, but given the fact that I wasn't willing to put in the effort/expense to integrate a sub into my setup, I think that putting them in the more appropriate sized room will bring out their best.

YEs, I would say MartyKL is the one to talk to with the most experience I know of regarding use of OHMs with subs and tube amps and how that setup might compare to others.
