I owned a pair of Bic PL26. Identical to the FH6-LCR except the PL26 has a nicer cabinet. I dont listen at reference but the 170 sounds a hell of a lot better.

I don't know, I didn't hear it that way. Maybe there is something I'm doing wrong but I can't imagine what. When I turned up the 170s they sounded great but then I keep expecting it to clip. My AVR goes to 16db and I cannot get over -8. I know that number is relative but I would think I have ALOT of headroom, not clipping at just over halfway.

I am thoroughly happy with their volume. So when I stated "improvement", I meant in quality, not output. But I did not expect to have to give up so much in volume as a compromise. I do appreciate you answering my questions, David.

It's my pleasure.


I certainly understand your intentions, but even similar volume levels will not be achievable. You are in a rather difficult predicament - if you are looking for similar volume levels in your system (106dB from each speaker at 10.5 feet back) while using your current receiver, you are going to have to spend considerably more $$$. Take a look at high-efficiency speakers from JTR and Klipsch.


One of the ways a loudspeaker achieves such high efficiency is by compromising in the frequency region you are specifically looking to improve. Google Hoffman's Iron Laws of Speaker Design. You basically have 2 choices, if you want improvements in this frequency range, you will have to make significant compromises with regard to overall volume levels in your system, or - you will need to go with a high-efficiency loudspeaker that uses a much larger speaker cabinet compared to your BIC's.

Volume level position on a receiver has no relation to how much power the receiver is or is not producing when comparing one speaker to another. It sounds like at -8dB, you are demanding more wattage from your receiver than it can reproduce. In addition, running YPAO might make this significantly worse if it is applying any boost in any frequency range. My recommendation is to completely turn off YPAO and then check.


Having said that, this is somewhat moot though as you will never achieve the volume levels you desire with this combination of speakers and receiver.


Just like you can purchase a car built for speed, or for fuel efficiency, or for lugging around a family or for off-roading, loudspeakers are also designed for different goals.

Lol! Cmon, David. I hope that was a joke. Are you trying to tell me there are no quality speakers out there that play from 80hz up (not 60) at around 90-95db sensitivity,(not 101) and will output about 100-105db, (not 134) for under 3000?!? Just using an extreme example to make a point, right?

No Jas, I am certainly not joking. I am simply trying to assist you.


There is a tremendous variance in the requirements you just posted. I strongly suggest you narrow these down before your next speaker purchase.


If you are looking for a speaker that will reach 100dB at 10.5 feet back with your receiver, our CMT-340SE will work for you. If you want to reach 105dB cleanly without clipping your receiver, you will need a speaker with at least 94dB sensitivity, and most speakers with this high of an efficiency rating will have somewhat compromised performance at 80Hz, unless you go with something quite large. So, my recommendation is to either give our 340's a try or look for a well reviewed loudspeaker with a larger volume cabinet than your BIC's with at least 94dB sensitivity (that is documented). Please understand that while it might seem trivial to you between a speaker reaching 100 - 105dB, reaching 105dB will require approximately 4 times as much wattage as reaching 100dB.


Not to confuse matters even more, but you must also determine if you are looking for "peaks" of 100-105dB or if this level is for continuous playback. If continuous, you will need to account for at least 10 of additional headroom.

Great sound at reference level isnt cheap. A preamp would also be helpful. Then you would have more power and not be limited to high sensitivity speakers.

I don't know how people listen at 80 db or higher. I could never tolerate it, especially when listening to music at home

Peaks, of course. Going by this resource here on this site, I see at least a dozen.
https://docs.google.com/spreadsheet/...owsperpage=250

According to this graph there are many that meet my requirements, (Granted, much of this info is not likely verified, but hey, if I can't trust AVS....) and from a quick check the majority of these are much cheaper than quoted. But all I need is a range, nothing hard and fast. I just bought a Klipsch RS62 II from Amazon for $340. The chart claims to reach 105 with the wattage I have available. Even if it's close It should be more what I need. I see what you mean about the 500 watts for the 170s. I guess I just need a little less beauty and a little more beast.

Per sound and vision HT labs Measure;
"The RC-62 II’s listening-window response measures +3.39/–3.88 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +3.96/–3.75 dB from 200 Hz to 10 kHz. The –3-dB point is at 72 Hz, and the –6-dB point is at 60 Hz. "

I will let you know how it sounds in a couple of days. Thanks again for your time and advice.

P.S. I may not have been expressing myself properly, the fact is these 170s don't do it for me. My concern was that I may have done something improperly but it seems clear my biggest mistake was to trying to explain these speakers are just not efficient enough for me. I don't have any specific requirements... just loud, clean and decent sounding! Thanks again!

Good luck Jas and I am happy that I was able to provide some insight. No, I don't think you were doing anything wrong with the 170's, just that these are definitely not the type of speaker you are looking for.


The RC-62 II is very similar in size and overall design to your BIC's... I am most curious to know if you find them to be an improvement over the BIC's

It will definitely be an improvement over the FH6-LCR. What are you going to use as mains? You really should get the rf62s.

I'm trying to avoid towers. I'm not sure what I'm going with. I'll use the fh6s for now. I want to make sure I'll be happy with the center channel.

Your avr's reading of 16dB is irrelevant without a calibration with a change of speakers, did you do that? What's halfway? You know a dB scale is logarithmic, not linear, right?

Actually, the klipsch are about 50% larger and twice the weight. They look great and the sound is night and day. Along with the 2x RB-81 II, it came to $1050! For three speakers!

The 340s are better speakers imo and would have been $150 less.

Ummm...I realize this is WAY OT but there are a lot of reasons that Buddhism was never an option for Constantine....For one, there wasn't a substantial community in Rome in the early 300s CE. {EDIT: actually an insignificant number.}

So, an update on the return process. I shipped the 3 speakers back to Ascend on 10/10 and notified them it was shipped and emailed them the shipping info. On 10/22 I emailed them to ask if they received the items since the UPS site said it was delivered on 10/15. Since a week had passed since that date I was expecting some sort of acknowledgement of receipt. I was emailed that the items were received a week earlier and that the items would be inspected and credited on 10/24. That's the last I have heard. Will update when items are officially returned and credited.

Since a week had passed since that date I was expecting some sort of acknowledgement of receipt. I was emailed that the items were received a week earlier and that the items would be inspected and credited on 10/24. That's the last I have heard. Will update when items are officially returned and credited.
No need. Your not the first to return some speakers and the business practices of Ascend have never been in question. Outstanding.

Glad you're enjoying the Kiplish speakers, but Bond is not the only one who thinks you could have done better for less.

Hey guys,
I am considering an upgrade and want some opinions.
I am currently using Klipsch KB15s for front heights in a 7.1 setup in a room that is about 13' x 18'.

http://www.klipsch.com/kb-15-bookshe...s-pair/details

My current system is Yamaha RX-V675. CMT-340 SE mains. CMT-340 SE C center. CBM-170 SE surrounds. Klipsch KB15 front heights. Rhythmik LV12-r subwoofer.
I was wondering if I would hear a significant improvement if I replace the KB15 with another pair of CBM-170 SE.
I wouldnt expect much of a difference with movies but I listen to a lot of music in 7 ch stereo so that's where I'm hoping I would hear the most difference. Also, I live in an apt so I don't ever listen at very high volume. -20 on the master volume is as loud as I ever listen.
Thanks

Anyone know where I can find a wall mount for the CBM-170? The ones at Ascend have been discontinued and unavailable for a long time. I found a couple that I can modify but nothing that will work out of the box.

I have used the Pinpoint variety of these http://www.amazon.com/VideoSecu-Clam...pinpoint+mount

Thanks.
Those are actually the exact mounts I'm using for my KB15s right now. Problem is they only tilt 7 degrees. That's fine for surrounds but not nearly enough for front heights. I'd like something that will tilt about 45 degrees.
Also the 170s have rounded edges so I'm not real confident of the clamps. The side pieces of the clamps don't come up very far.
You say you used them with the 170s with no problems?

Yes, I have used them but didn't need that big a tilt....there used to be a heavier duty Pinpoint ball-type mount (the 30.0?) but don't think they're available any more and IIRC they weren't quite robust enough for the weight of the 170s (tried them with 200SEs and that was problematic). Maybe its time for something creative like flying them using a net or cradle hanging from a ceiling hook or similar? Maybe not the prettiest solution....

lol At this point I may consider it.
Yi, most of the ones I've found wont hold the weight or only have one screw sticking out. Wonder if the 170 would be stressed if I held it in place with just one of the screw holes? Probably need to ask Ascend that one.

The ball mounts I had had a bracket that mounted using both 1/4x20 insert holes on the back of the speakers, enabling a single larger bolt on the mount itself....but I'd think one is sufficient but would tend to tilt/center around that mount....

Curious, where do you sit where a 45 degree tilt is needed on a front wall?

I sit about 7 feet from the wall and the height speakers are about 8 feet from the floor.

15-20 degrees downward and you are good to go. Try these:
