OK. So I've got a HT (the audio only system is downstairs) with the following:
Room is 15x13x8 that is a 2nd floor landing (so it's open to stairway to 1st fl).
Equipment includes Hales Rev 3 and Hales RevCenter with a pair of Sonus Faber Concertino satellites for rear. The current sub is a Def. Tech. PowerField 1500.
Using an Integra DTC 9.8 (Theta Intrepid amp for non sub speakers). Using Epson projector and screen clearance is about 18" (so this curtails placing a pair of subs at room front, I'm afraid)
Like to keep the cost of the sub under $2k.
Size is not an issue nor WAF. Not worried about looks (hey I use "ugly" open cage tube stuff in my audio system)
This is a dedicated HT.
Goal is effective and accurate low frequency response delivered from source to my ears.
From Craigsub list I was thinking of SVS PB-13 Ultra or similar Epik or ED but I'm not absolutely clear on which of these will work out best, let alone whether I need to even upgrade.
Aside: with my new pre (Integra) I've set it for LFE only (no other low frequency from other channels sent to the sub) with 80hz as low-pass filter (setting the control on the speaker all the way up to 100hz so that I'm avoiding it's electronics getting in the way of messing with the signals.
Not sure these are the right settings but I don't think I'm hearing problems (distortion) in my system. Anyone with insight....please chime in here.
