Hello people I have been wondering if there are any members here that own or have owned an SVS PB12-NSD and used it with a Hsu MBM-12 midbass module??? If so, please share your impressions/oberservations with us. My room is just a tad bit under 2000 ft^3 and when watching movies my PB12-NSD really kicks as* if you know what I mean. However, the same is NOT true when listening to music. That is, the PB12 does not give me enough output above 35-40 Hz range where it is needed for tight articulation. In other words, I need more output in the 30-80 Hz range so as such been thinking about buying me a Hsu MBM-12 midbass module. If I do this, will this give me what I am looking for? Are there any other alternatives with respect to cost(s). What I am implying here is that I have a very tight budget. Been thinking about plugging the 4" port on the PB12-NSD BUT havn't done so because of fear I may damage the 12" NSD driver. I would had been better off buying a sub that offered me a better balance of the two extremes-one being ht performance and the other being musicality. I really do not need a sub to dig to the lowest depths BUT rather one that is capable of digging low while at the same time remaining quite punchy and articulate when listening to music. Perhaps, getting a second PB12-NSD may solve my problem but not sure. I have experimented with various placements as well as X-over frequencies. As a result, the PB12-NSD is currently placed between my mains with a X-over set at 100 Hz. When it was placed in the upper right hand corner I used the 80 Hz X-over setting. But to be honest, I have NOT found any significant improvment in performance with any placement. Just seems to sound and perform about the same. I also level matched the sub with my RS meter for better integration. My guess is that since the PB12 has such a large cabinet that by plugging the 4" port may allow the sub to offer me more midbass impact and articulation. Am I correct? Please help if you can as I am open to any and all suggestions. Thank you for your time.
