I'm using the 6.5 inch ceiling speakers as surround sound for a home theater. In order to minimize sound transfer to the floor above, are there specs for building out a box in the ceiling joists and any recommendations on how to best do that and actually be successful in minimizing sound but not causing the sound quality to suffer? I saw reference in another question related to this and it said specs would be posted, but I could not locate. I know there are boxes monoprice sells but looking for another low cost solution that would assist with this.

I built boxes using rigid foam insulation, cutting a piece as wide as the joist bay, and making two cuts allowing me to "fold" down the sides next to the speakers. I attached and held everything together using spray foam insulation - I was able to do this for the speakers (as well as all my ceiling mounted lights, cans and wafers) because I had access to the attic and wanted to keep loose cellulose from the tops of them. on a ceiling between floors, you could use smaller pieces of rigid foam to build a box from the access hole for the speaker. Just be aware that these speakers are relatively "deep" and be sure to leave room for wiring access etc above the speaker depth.

I can't speak to the noise transfer to an upstairs floor however they are very directional. With them playing television sound at normal listening level while in my attic you really can't hear them much. I used roll insulation to cover when installing and that will help too. Run your wires, cut the whole, stuff that round and a piece of insulation in that whole leaving the cutout round in the attic and wire. No mess and likely minimal noise transfer. I do have a dedicated sub for low frequencies and that will make a difference too. Lower frequencies running through them will likely be heard above but very little if at all.

The best thing to do is to put insulation up into the joists above the speakers if you are finishing out your basement and have the luxury of adding this prior to putting up drywall then you are golden. Otherwise just stuff some batt insulation around the speaker.you may want to stuff a bit more along the sides running parallel with the joists. You won't be able to completely eliminate the sound but it will greatly help.

I've used some thermafider high density soundproofing insulation. I tried to stuff as much as I can with out removing lots of drywall. Theres a huge difference , but you still hear muffled sound but as bad as without. Its cost effective for 15 buck per roll you can't go wrong.

No know specs to build a box but what I’ve done is install mineral wool insulation (Safe&Sound) and i’m grabbed a large empty container of ice cream and glued it to the back of the speaker. It sounds amazing and adds good bass to it.

The specifications on the Alpha Ceiling Speakers 6.5-Inch Carbon Fiber 2-way say the cutout is 8.66" x 3.43" (220 x 87 mm). Shouldn't it be a round hole? If it is should I assume that it would be an 8.66" round hole?

Honestly I'm guessing, but the 3.43" could refer to how "deep" the hole must be into the ceiling. For instance, I have a bulkhead under a heating duct with insufficient depth available.

no you can't really angle anything, You can spin the whole speaker in your ceiling hole to move the tweeter a little, but probably not noticeable.

Is the woofer itself actually 6.5" as listed in the specs? Or is the entire speaker diameter roughly 6.5" (with what, I'm guessing, would be about a 4" woofer)? Because that's what it looks like from the pictures. Also, what are the tweeter and woofers crossed over at?

Maha,
The number in the description is the diameter of the woofer, so for the 6.5" that is the diameter of the woofer and the cutout for mounting is roughly 8-inch diameter. There is a cardstock circle template in the box for the cutout. I however do not know the crossover specs.
Enjoy!

How many of Product # 13684 can be wired in parallel and/or in series per channel?

BEST ANSWER: It depends upon how many Ohms in total you are trying to accomplish. Identical speakers in series (similar to Christmas tree lights) add up with each speaker sharing the applied power. The other method of parallel connection of speakers lowers the total resistance as seen by the driving amplifier - a far more dangerous and damaging type of connection if too many are connected in parallel improperly draws excessive current from the amplifier. This would be the best application for a 'speaker selector/impedance matching" device. Those have 'transformers' that 'upscale' each speaker's impedance so that the driving amplifier is not overloaded. The downside of those devices is the labor and wiring necessary to bring each speaker's cables back to one location - a lot of attic work!

I need to run as many as 8 speakers per zone. How do I make that happen?
- Reply
- Jonathan W on Nov 10, 2017
I just want to confirm 4 speakers can be wired to each zone(or 2 speakers per channel). Each zone has a 4ohms, 70v, or 100v wiring option. 4 of these Alpha speakers wired in parallel would be 2ohms of total impedance, which to much for the 4ohms label. I don't see a connection for both left and right channels on each zones output, so I don't understand your prior answer of "2 left 2 right per channel". Just on the input do I see left and right options. If I understand it correctly, both the left and the right channels are combined on the output. How should I connect 4 of these speakers on a zone when the label says 4ohms is the impedance? In parallel? which terminal, 4ohms, 70v, 100v?

The Cutout dimensions in the full specs are right on. I used the circle cut-out template which came with ALL of my speakers which gave me an exact fit. I mounted my speakers between the joists in my basement with the greatest of ease.

For new construction (2x8, 16-inch on center beams) will the Metal Back Can for 6.5-inch Ceiling Speaker fit in the space and can the Bracket & straps properly mount to the beams? (I had to return the 8-inch speakers and metal brackets because they were too big and straps appeared designed for a drop ceiling).

RR & RL home theatre
I installed these as my rear channels for my 5.1 theatre. They are roughly 9ft from the listening position with the tweeter facing said position as much as possible. For their purpose their great. Clear, bright, decent mid (they'll warm up with break in) and good quality. Pair with a good sub and you won't be disappointed. Easy instal and they look great.

Buy em, don’t hesitate, best round speaker available from Monoprice
Great speaker, great value, could be better. I am really happy with these, but I feel there is a lost opportunity to provide a backer box / rough in ring. Especially, since they have a blocked port, that can be opened to create a fuller sound.

Only had them a few days. Soooooo...........
just installed these Alpha series in ceiling 6 inch speakers. I tied them to the Monoprice 25 watt Hybrid tube amp. I am very pleased with the performance so far. I have not cranked em all the way up yet. I have not had them in long enough for break in period. I have gone half way and they sound remarkable. One thing to note. I have a android phone, the music app I have used for years STINKS. I just tried using a app that is a Equalizer and sound boost in one and it made a HUGE. Difference in sound quality. I am so impressed with these Alpha series speakers paired with the cool looking Hybrid 25 watt Tube amp. Will take them to full power in a week or so. Will try to let you know if there was any clipping.
