    Pioneer VSX-82TXS or Denon AVR-2807???

    I'm looking for an A/V receiver in the $1k retail range. Two that have caught my eye are the Pioneer VSX-82TXS and Denon AVR-2807. I need my receiver to power a 5.1 or 6.1 (haven't decided yet) set of Speakercraft in-ceiling speakers. Component-wise I have an Xbox 360, a Directv HR20 DVR, and...

    $800 and 200 sq ft

    Certainly a lot out there for that budget and that small of a room. I would recommend buying an SVS PB-10 and an EQ. Then you'll have money left over for wall treatments, bass traps, etc. and DVD's! Good luck!

    Can I plug the port on my PB-10?

    It's OK to do. I think Ilkka, a HTF member, tried it and wrote about his results. Just use anything you've got around the house to plug it and see if you like it. If your results are positive I'm sure you can find a foam plug somewhere on the net.

    Ok, fixed BFD and replotted

    Great Job Mikey, Now I'd try a 1/6th octave-wide 5 dB cut centered at 36 Hz.

    Dayton SUB FR Plotted-PRE BFD-Advice?

    It looks like they're compensated readings because they were entered into Sonny's spreadsheet. Before you go moving your sub get the SPL with your sub and mains active.

    BFD trouble-HELP

    The cause of the ground hum is a difference in voltage between two power loops. I bet if you plugged your sub, receiver and BFD into the same outlet or circuit the hum would go away. You can use a cheater plug to remove the ground prong as GrahamT suggested but your sub may be damaged if a power...

    Dayton SUB FR Plotted-PRE BFD-Advice?

    It looks like this FR is for your sub only. It would be more appropriate to take SPL levels with your sub and front mains playing the tones. That way we can get a better idea of your FR near your internal crossover setting. At first glance I wouldn't use any filters centered at below 36 Hz.

    pb12-isd comparable to b&w

    If you love low, deep bass you've love the PB12. In this respect there's no comparison IMO. The cylinder equivalent model from SVS may even be more to your liking.

    DIY Tempest freq resp... BFD help

    al lout- Working in 1-Hz increments is overkill. Its only benefit is finding the center frequency to set the filter. In addition to being very labor intensive it emphasizes negligible volatility IMO. It also looks like you're introducing more volatility by using too many filters or filters...

    Rear speaker placement question

    I wouldn't get hung up on positioning them precisely at 110 degrees. It would help if you could provide a diagram of your room. Mounting them to the ceiling is fine too. As long as your rears aren't huge there are ceiling mount brackets available. Just experiment first before you start drilling...

    Rear speaker placement question

    One more thing. Some favor placing their surround speakers on the floor facing up toward the ceiling at 110 degree angles WRT the primary listening position. If there's no danger of someone tripping over them you may want to give it a try!

    Rear speaker placement question

    Ahh, the eternal question... Ok, if you have dipoles/bipoles then I don't have much to say since I don't have either. If memory serves, bipoles/dipoles should be placed immediately to each side of the primary listening position so you're in the "null". If you have direct radiating type...

    http://www.thielaudio.com/models/Cur...bs/subwo1.html I'd be happy with the SS2 myself. Two 10's and a 1000W amp is all I want. If only I had $5k! I can't imagine what the model with dual 15's sounds like. I wonder what it would cost to build a replica?

    An SVS, a BFD and 4 hours...

    Just to clarify, the BFD comes pre-configured with presets 4 and 5 in parametric mode. You can use any of the 10 presets in parametric mode if you choose to. I have a question though about using one preset for movies and one for music. For those of us with smaller HT rooms (

    An SVS, a BFD and 4 hours...

    Bass is output from both your mains and your sub just below and just above the LFE crossover frequency. In other words, with an 80 Hz crossover setting your AVR will still send out an LFE signal even if it's playing a 100 Hz frequency. That's why phase is so important. The proper blending of...

    Nice work Robert, but where did the dip at 111 Hz come from? Perhaps you used too many filters?

    Attn EQ Experts - Am I over-EQing?

    In retrospect, I now understand that 11 filters was overkill to adjust my FR. I ended up with 7 filters but could have gotten away with only the 4 centered at 23, 39, 49, and 79 Hz. When playing frequency sweeps I don't really notice much of a difference between using those 4 and the 7 filters...

    Attn EQ Experts - Am I over-EQing?

    I think I'm getting the hang of this. Four filters did a majority of the flattening and another three filters cleaned up what was left. Check out my before and after frequency response: Short of applying a shelving filter for a house curve I think this is as good as it's going to get. I...

    Soundproofing my sub to quiet my neighbors complaints -mini review

    Hi Mylan, Without actually trying it I doubt anyone could say for sure whether a subdude would fix your vibrating cabinet. Increasing the distance between your sub and cabinet is an easy and free thing to try. Otherwise I'd try putting some dampening material (cork, foam, soft plastic, etc.)...

    Soundproofing my sub to quiet my neighbors complaints -mini review

    Hi, For those of us with nearby neighbors that don't share the same love for HT and bass that we do I recommend the folks at www.soundproofing.org. Here's my experience with them and their products: I live in a condo and share one wall with my neighbors. With them in mind I followed my...

    Attn EQ Experts - Am I over-EQing?

    Good info Wayne, thanks. I think I'm getting the idea. Consider my first FR plot above. Even though my peaks and nulls aren't truly symmetric I can see how I could clean up most of them with only these 4 filters: Center Freq (Hz) / Gain (dB) / Bandwidth (octaves) 23.0 / -11 / 0.50 39.0 /...

    Attn EQ Experts - Am I over-EQing?

    Hi Mark, My interpretation of what you're suggesting here is that I Turn off my sub and measure the SPL of my mains in the 70-120 Hz range. Then, turn off my mains, play the same frequencies though my sub and increase the gain until its SPL matches (or is slightly hotter than) that of my main...

    Attn EQ Experts - Am I over-EQing?

    Thanks Mark, I ran home at lunch to run through my frequency response with my sub at a different location. The compensated values are shown in the chart below. I was able to get rid of the 80 Hz null. The 40 Hz null is a bit of an enigma. There is a significant drop in SPL from 39 Hz to 40...

    Attn EQ Experts - Am I over-EQing?

    Hello, I'm trying to flatten out the frequency response curve of my PB12 using the BFD DSP1124 PEQ. My FR curve* Given the volatile nature of my FR I would assume that at least a half dozen filters are required. However, I could also see using as many as 11 of the 12 filters to...

    Neighbors & bass- Does facing the port away from the wall help?

    Hi all, I want to do everything possible to minimize the bass and vibration my neighbor hears on her side of our shared wall, before she feels the need to complain. I already listen at -20RL and the sub is located along one of the walls perpendicular to the wall we share. Will turning...
