Hey guys. It's time for me to get serious about adding some authoritative BASS to my home theater system. I could use some advice.\n\nI am looking to add 2 subs to compliment my system. It is for a room about 16x15, with the left wall open to a hallway and kitchen bar counter. The lowest level of bass that I'm willing to consider is the HSU VTF-15, since I can get 2 for around $2k, and they come with a nice finish.\n\nWhat would be some subs that are a step-up in clarity or power from here? The caveat is this: My wife will not accept a sub with a black veneer finish like the Monolith sub, it would need to be a furniture grade satin or gloss black. \n\n(**I'm trying to gauge what subs of similar size could even provide superior performance? If so, at what cost?)\n\n\nI have probably added some equipment since I last posed here, so here is a current summary of my 5.0 system:\n\n\nMain L\/R: Polk LSim 707\nCenter: Polk LSim 706\nSurround: Polk LSim 705\nPre-amp: Denon X4500h receiver (no amps utilized)\nAmp: Emotiva XPA-7 gen3 (only 5 channels utilized)\nInterconnect Cables: Bluejeans LC-1\nSpeaker wire: Belden 10awg\nMedia player: Xbox One X \n\n\n\nNote:\nFor those people who are curious: I was previously driving all 5 speakers with the robust Denon X4500, but it became fearfully hot to the touch. When I changed to the the Emotiva XPA-7, however, it really woke up the speakers and added some noticeable bass. It wasn't a "night and day difference", but the Emotiva definitely added some power and authority, as well as a bit of clarity and "openness" (for lack of a better word) that was lacking before, especially at louder volumes. The main improvement that was noticeable was that bass was much stronger. Machine guns and explosions on Saving Private Ryan now hit the room with visceral authority... at least compared to what I was used to.
