I sold my SVS PB-3000 subwoofers with intentions to swap to the PB16 Ultra or even try out the SB16 Ultra as I typically run my subs sealed. Out of curiosity I ordered two D6000 subs to play with. I had 0 intentions of keeping the subs as I thought they may sound bloated and not be a good fit for music.

Ive since thrown out the boxes and will be keeping both D6000 subs and would highly recommend these to anyone looking for new subwoofers.

These are better than my SVS subwoofers. I would say the sound signature is similar to SVS, providing the subwoofers are dialed in to account for the rooms peaks and nulls. However the D6000 has a lot more output and the ability to play at the same volumes effortlessly where as the PB3000s had to be pushed pretty hard to get the same output leading to distortion/ driver noise and port chuffing.

I've run these subs both ported and sealed. The built in DSP accounts for using the port plugs and both profiles work great. After running Dirac a few times and making multiple profiles for sealed and ported, I ended up liking the ported profile just as much as the sealed. Just goes to show that these subs can be gentle giants providing they are set up correctly.

Music is very detailed and the subs blend perfectly with my mains( Kef R11 Metas) which is what I was worried about initially for a budget subwoofer. Budget by no means means compromised sound quality in this case.

Movies these subwoofers shine! The ability to rattle your room if you want or to blend in and hide amongst your speakers with clean impactful bass. These subs can do it all!

Room Dimensions:
20'x20'x8' Slightly Asymmetrical as there is a dry bar to one side. Not closed off to the joining room.

These two subs still pressurize the room and have a lot more gas in the tank.

I previous have a 200 Watt 12" Sub with passive radiator. This is a wonderful upgrade. Should consider getting a pair if want to match cinema level acoustic effectiveness. And yes, be wary about neighbors complain :).

Hi All, yes here I am again ! I saw this sun on Spec of Teck and wanted to see for myself! Yes it truly is a really good sub! , I tried it with music at first, using Dua Lipa , to check the bass out with music! I did not even tweak it, and boy it has great bass! I used it for Apple plus also , it rocked!. Next I used it just for a blueray with music, Burlesk movies! Yes good sub for less than half the price of a pb16 ultra! And yes i have expensive subs as well,, jtr, Captivater ulf, Paradigm xr13! And i have 8 svs subs as well, plus others(7 systems) Thing is if you want a 800 watt rms 15 inch sub! For a great price and powerful, then here it is! Trust me you will love it! Thank you Amir, he's a really good person to deal with! You also can see me on my own Facebook page Audio Video Maniacs, yes im the biggest group Toronto Westwards, with over a hundred countries and over 6300 members! You can say hi , tons of great people! Thank you, so buy this sun,,,,, you won't be disappointed!!!! Boom!!!

I have previously purchased Tonewinner amps and was quite impressed with the build and sound quality. Decided to take the leap and purchased dual D6000 subs and I was pleasantly surprised. They completely transformed my movie watching experience. I can now hear lows that I never thought existed.

I had previously thought of purchasing SVS PB3000s but these subs provide better performance at a fraction of the cost. Totally recommend these subs to all audiophiles out there.

In addition, the customer service offered by Aamir has been stellar. He always picks up the phone and is available to answer any questions I may have. You will not be disappointed in dealing with Summit HiFi.

This is a fantastic subwoofer. I've had numerous subwoofers in the past such as svs,(several including 2 pb3000), velodyne, paradigm, Jbl,
martin logan, klipisch, psb, energy , polk audio, Psa, Kef, Rsl, plus others . This one is definitely my favorite and it's absolutely unbeatable for its price. It plays good quality deep sounding bass and rumbles the couch as well. Also It looks great and the rounded edges i a nice touch . It's an impressive subwoofer and I don't hesitate in recommending it. My advice is buy one before it increases In price because I'm sure it can't stay this cheap forever. Also important note is , Aamir is awesome to deal providing superior customer service.
Highly recommended.

I recently purchased a pair of these subwoofers and have to say they’ve exceeded my expectations in terms of output and low-end extension for the price. Coming from SVS PB-1000s, these subs play far deeper and have a thicker, heavier sound that is amazing for movies. They sound great when listening to music as well, also sounding quick with little overhang. I was initially somewhat sceptical of the rear port for possible complications with placing their back up against a wall, but I currently have them about 6 inches away from the wall and they sound perfect with no port chuffing whatsoever. I would highly recommend these subs for people on a budget who don’t want to compromise on performance. Thanks Aamir as always for your amazing customer service!

Just got 2 of these subs..All I can say is WOW.
I can't take the smile off my face .They exceeded my expectations by large.. I have tonewinner amps and love them, but was not sure about their subs..
After the great communication with Aamir and watching Spec Of Tech YouTube reviews, from Barrett I was hooked..

I had paradigm ,SVS pb,3000, and JL subs..
To my surprise, this 15" was by far the best sounding and powerful in my house...I can't get over the punch in get, and ultra low deep end..
The sub also looks amazing...Looks high quality ..
I can't thank Aamir enough for educating me these subs and about tonewinner.
I'm a believer now and spreading the word .
If you want killer low powerful bass with crazy mid bass punch, look no furthur...

These subs sound like subs much more $$$$

Thanks again....I'm so happy now with real bass.

I was previously using a Denon x3300w receiver and I always found it lacking when it came to dialogue and action scenes. Decided to purchase the TW AD7300 V2 amp from Summit and I have to admit that the my home theatre came to life! Dialogues sound more crisp than ever and audio does not distort during action scenes as it used to with the Denon AVR.

More importantly, Aamir is nothing short of a phenomenon! The customer service he provided was spectacular and I am convinced that I’ll be returning to Summit for future purchases.

Thank you Aamir and Summit HiFi!

This amp is terrific. Built like a tank and gorgeous in the rack. The large VU meter is a beautiful bonus but the powerful clean sound is the showstopper. Aamir has the best customer service in the business. Thanks again.

This sub is a beast. Shakes the house. Deep and loud. Makes my SVS PB 2000 wimper with envy. You can't get a sub anywhere close to this for the money. Thanks Aamir, you are the best.

This is a fantastic amp. I'm impressed with how it looks and sounds . Aamir is awesome to deal with
Providing excellent customer service. Highly recommended.
Thanks Aamir.

I am writing this review so others can have an idea what this "unheard of amplifier" is all about. I took a chance. Aamir highly recommended it. Very very impressive! The AD 5180 is really a "WINNER" :-) Build quality is outstanding, fit and finish, flawless. On receiving the AD 5180, before connecting it in my system, I took it to my (old) go to HiFi store in Calgary. A small high end shop. My friend was skeptic, and unsure, so we connected the Tonewinner AD 5180 into a decent system. A $5.5K Anthem STR Amplifier, very nice! (200w x 2, close to the same power), paired with Paradigm Prestige 75F tower speakers that was set up. Played a few hi res tracks we both know very well, impressive! Then we connected the tonewinner AD 5180 using the Anthem STR pre outs, It woke up the Paradigms with authority and finesse! The sound had better body and dynamics over all in comparison. That impressed us as the Anthem is over 4 times the price and the AD 5180 was as good as, if not better. Ok, good, ....NOT. We paired it with a 7 yr old Yamaha 2 channel Amplifier that was preowned, same speakers, same tracks, same volume to keep things equal. Holy @#%!!! We both were blown away. I had every hair on my body stand up! (my friend also) A wow moment. The soundstage was incredible. Drums, cymbal hits, bass, vocals were something to behold. Cleanest amp I have ever heard. Zero noise, zero distortion at out listening level (-18) Its not easy to impress a Audiophile who has also been in the Audio Hi Fi biz for 30+ yrs, me either! Hats off to the AD 5180!!
Aamir has his finger on a incredible product line. Not only is it a 2 channel high end beast, now I have it in my HT system!!. SVS Prime Pinnacles, Prime center, SVS SB4000 sub, all from Summit Hi Fi. Nad T758 7 ch AV Reciever (pre amp now) Paradigm Monitor SE 6000F towers as surrounds, Definitive tech bipolar rears Sony X800M2 4k Blue Ray. After some set up, No room correction, fired up my go to demo Mad Max Fury Road 4k was my first movie. I was again very impressed. The dynamics, clarity, detail and soundstage this amplifier provides is no joke. Not the slightest hint of distortion, or it ever running out of chest pounding power. It will blow away any AV receiver on the market hands down. (checked for gunshot wounds after John Wick 3!!) I drove it hard until my ears gave out. Class A/B amps run quite hot, but with the AD 5180 I could still place my hand on top of the amplifier!
The AD 5180 I would say is a fairly neutral amplifier. Pair it with different gear and it will reproduce the sonic signature with pinpoint accuracy, plenty of clean ultra low distortion power to drive ANY speaker set up. The spec's as far as I can tell are there. In conclusion, the Tonewinner AD 5180 is an incredible value, build quality, great looks, and solid high end performance. Thank you Aamir!

BLOWN AWAY !!!! This is the first thing I can say ... not only is it insanely powerful, it looks beautiful. I am running the amp with a Macintosh pre-amp and a Marantz NA6006 DAC driving a pair of VERY thirsty flagship Polk 707's and the result is one of the very best sound stages I have ever heard in my life. HUGE thank you to Amir for setting me up with one of these, now I just need the 5 channel to complete my surround room !!

Sincerely
Steve Heck

Was currently running a Denon AVR-X4000 with new KEF Q950’s. These speakers were a great upgrade from 20 year old Polks, however felt they lacked a bit in the mid range. This amp brought these speakers to life. They were brighter, more punch and clarity. Bass and drums really stand out. I would recommend this amp to anyone for value and build quality. The meter was larger than expected, however the light is dimmable and looks fantastic. Aamir was great to deal with and everything promised was fulfilled. A 45 day trial period is a good perk but in this case not required. My wife let me peel the protective plastic off the front within a week.
