Quad 2905 versus Quad 2805 plus subwoofer

To Willemj: Hi, I'm also matching my electrostatics (in this case Soundlabs) with DIY open baffle woofer towers.
I'm curious about the sound of your system. Maybe the insights derived from listening to your system can be of additional value in the process of finetuning (of my own system).
Do you live in The Netherlands?

Yes I live in the Netherlands. In the meantime i have lowered the crossover further to 33 Hz and increased volume to 83db sensitivity. This makes the sub disappear just a tiny bit more. As I said, integration with the Quads is now fine. Integration with the room remains a bit of an issue, especially at lower frequencies. And that is with a (beautifully reconditioned) Quad 33/303 amplifyer with a low cut filter that removes all the really low frequency junk.

My experience with the sub has persuaded my that subs do indeed have undesirable issues with room acoustics. I can make those tolerable by turning down the sub as I did, but that almost defeats the purpose of the exercise. So I am now considering an Anti-mode 8033 room equalization system. I would be interested if there are people who have used one with a system like mine.

I bought an Antimode 8033 cinema and it works a treat. Room modes have virtually disappeared. The sub now sounds as tight and fast as the main speakers. Bass extension also seems even lower. Even with boomy recordings the sound is much improved. There is only a little bit of experimenting left to do, and then I can stop thinking about audio, and just enjoy the music.

I have 988s fully upgraded by Electrostatic Solutions and with the Mye Stands. I recently bought an REL S5 subwoofer and find that the reviews were correct - it blends in seamlessly with my Quads. I have the REL engaged at around 35 CPS, so the REL supplements the full range Quads. Highly recommended.
