Are There any Space-saving Alternatives?

Tom,

For low frequency absorption my tests show that the denser 705 is better at the lowest frequencies - those below what the published specs report.

> Rockwool will also do the job won't it? <

Absolutely. All such products are fairly similar, and all come in a variety of densities.
